source.python's Issues

temp_entities.beam_points

Hi there SourcePython developing team!

First off I'd like to thank you all for all your effort and energy that you have put into this project and all the tools you have provided us with, it's very much appreciated.
That being said I think I have found a bug, whether it is the code for the temp entities, or the engine in CS:GO itself, I do not actually know.

The bug that I have encountered is when you are trying to use temp_entities.beam_points and setting the start and end width to be two different values.
I've previously worked with ES:S in CS:S and when defining 2 different kinds of width it worked just fine.

However I am now trying out the same thing in source python, in CS:GO and it does not seem to work as I intend it to.
It is supposed to make the line get bigger/wider in one of the ends, however that is not the case, no matter which values you put in the start and end width the line always stay the same as one of the values.

E.g. a start width of 5 and an end width of 20 will then be a straight line with no change, probably using the start and end width of either 5 or 20.
If you guys want a look at it for yourself here is the example I used when noticing this:

laser = model('sprites/laser.vmt')

    location1 = defender.origin
    location2 = defender.origin
    location1.z += 5
    location2.z += 140
    temp_entities.beam_points(self._recipients, 0, location1, location2, laser.index, laser.index, 10, 10, 1, 5, 50, 0, 0, 255, 150, 150, 170, 1)

I hope this information is detailed and explained well enough, I did my best to explain it in the best way I could.
I hope you guys will be able to fix this issue as it will open up for a lot more of opportunities when it comes to working with effects in SourcePython.

Sincerely

Incorrect debug message level in CSourcePython::OnQueryCvarValueFinished

A debug message is printed to the console when OnQueryCvarValueFinished is called if you have level set to 1 or higher in core_settings.ini.

To reproduce:

from engines.server import engine_server
from events import Event
from players.helpers import edict_from_userid

@Event
def player_say(event):
    userid = event.get_int('userid')
    engine_server.start_query_cvar_value(edict_from_userid(userid), 'net_fakejitter')

Results in something like:
Cvar query (cookie: 143, status: 0) - name: net_fakejitter, value: 0

May 21st release.

Not working player.give_named_item

Please check the next code:

from events import Event
from players.entity import PlayerEntity
from players.helpers import index_from_userid

@Event('player_activate')
def player_activate(game_event):
    player = PlayerEntity(index_from_userid(game_event.get_int('userid')))
    player.give_named_item('weapon_shotgun', 0, None, False)

This code should give the player chosen weapon. But now it's not working.

Steps to reproduce:

• Send a menu to connected client
• Change to another map, then rapidly disconnect the client

ConfigManager.execute doesn't execute the config file

Assuming the config file is called 'testplugin.cfg' and I have a ConfigManager object referring to it like this somewhere:

config = ConfigManager(CFG_PATH.joinpath("testplugin"))

... and this in load():
config.write()
config.execute()

It writes the config file.
Everytime I try to execute it (from a script) the console echoes 'source-python doesn't exist, not executing'. But when I execute the config file manually using the server command "exec source-python/testplugin" it works and does't output any error. ConfigManager doesn't do anything else than what I do manually, so I don't have a clue lol.

CSS: Windows server crashes when sending a double quotation mark to chat.

Bare CSS server, map; de_dust2, only SourcePython is loaded, no plugins for SP are loaded, type anything which includes one or more of: " , send the message and the server crashes. Replicated on a live server and on a test server running on LAN only. With both the last Py3.3 commits and the newest released Py3.4 build from the zip download.

menus.PagedMenu() close option to button 9. in csgo

For PagedMenu() I would like to have the buttons Back, Next and Close set to 7, 8 and 9 respectively because the 0 button is not bound by default in csgo (so stupid...).

engines.sound.Sound defaults to PitchTypes.HIGH

I'm assuming it should be PitchTypes.NORMAL

Unable to add hardcoded keyvalues

Currently, only keyvalues are added, which are part of a datamap. But there are keyvalues, which are hardcoded in CBaseEntity::KeyValue(). E.g. renderamt: https://github.com/alliedmodders/hl2sdk/blob/28b43b06249837c1517db1468af14678080715f6/game/shared/baseentity_shared.cpp#L339

Should we loop through keyvalue_contents and add them regardless of the datamap?.

CSS: Server crashes when sending only one or more spaces to chat [chr(32)].

Very similar to my last issue, but now with another character (I bet it's related to SP splitting commands by space?), typing one or more spaces crashes the server. Sending " to chat also crashes the server. (I'm running the build that fixed my last issue.)

get_color, set_color function throws an exception

I think this is due to that render_color is Color type and return object itself but not 4byte integer value as expected in code. Also set_color function throws a similar exception.

(CS:S) ShowMenu with lengthy message results in error

The following error appears in the server console when trying to send a menu that is longer than 240 bytes or so in length:

DLL_MessageEnd: Refusing to send user message ShowMenu of 256 bytes to client, user message size limit is 255 bytes

PagedMenu's top seperator can't be None, check missing

PagedMenu's attribute top_seperator raises an error if set to None due to a missing check in /packages/source-python/menus/radio.py on line 199 and 200:

<StringTable>.__iter__() causes infinite loop

When iterating over items in a StringTable instance, the items are iterated over infinitely. When testing for "item in", iter is used, causing an infinite loop if the item is not found in the StringTable.

from stringtables import StringTables

sounds = StringTables.soundprecache
for x in sounds:
    print(x)

from stringtables import StringTables

sounds = StringTables.soundprecache

sound_name = 'physics/plastic/plastic_box_impact_soft4.wav'
index = sounds[sound_name]
print(index)
print(sounds[index])
print(sound_name in sounds)

invalid_name = 'this/wont/work.wav'
index = sounds[invalid_name]
print(index)
print(sounds[index])
print(invalid_name in sounds)

Crash on server exit when calling entity input in unload()

To reproduce (TF2 Linux, May 21st release):

from entities.entity import Entity

entity = None

def load():
    global entity
    entity = Entity.create('trigger_multiple')
    entity.spawn()

def unload():
    global entity
    entity.call_input('Kill')

I've also tested the Ignite input resulting in a crash. I was running Sourcemod and Metamod at the time, but the crash also occurs with only Source.Python loaded.

RuntimeError: access violation - no RTTI data

It was though to find code that actually replicates this issue, because at first it seemed to happen quite randomly. There might be more cases then this one.

It seems to happen when passing/storing playerinfo objects to multiple functions; I'm guessing they go out of scope when the first function finishes execution:

import command_c

def h(playerinfo, command):
    test(playerinfo)
    test(playerinfo)

def test(playerinfo):
    e = playerinfo.get_edict()
    e.get_index()
    print(e)

def load():
    command_c.register_client_command_filter(h)

def unload():
    command_c.unregister_client_command_filter(h)

Running this code will result in:

<entity_c.CEdict object at 0x12345678>
(Traceback here)
RuntimeError: access violation - no RTTI data

Expose CSteamID

Any chance that CSteamID (returned by engine_server.get_client_steamid(edict) could be exposed? I'd like to use it to generate Steam3/SteamID64 (community/Account ID) tokens in a more future-proof manner than blindly transforming the client's authstring. Ex. https://github.com/alliedmodders/sourcemod/blob/ff27484527344ec3c5d591bd9610e07f00ff31de/core/PlayerManager.cpp#L1992-L2098

mathlib's Vector long float issue

I came across an issue where I precalculate long floats, and after initializing a Vector object, the x y z values differed from the original ones.
It looks like after the 9th number, mathlib.Vector() has a calculation error.

Example:

from mathlib import Vector

x, y, z = (-14.49353846153846, -10.87015384615385, 0.31507692307692)
vec = Vector(x, y, z)

print(x, y, z)
print(vec.x, vec.y, vec.z)

Result is this (on every 9th number it starts to differ):
-14.49353846153846, -10.87015384615385, 0.31507692307692
-14.493538856506348, -10.870153427124023, 0.31507691740989685

Add dump_datamaps to core/dumps.py

The function should require a datamap_t argument. This should be used to dump the datamap and all of its base maps.

Unable to find some properties

There are properties which can't be found by < Entity >.get/set_property_< type >(). E.g. this little script will cause an error, although the property exists (CBaseEntity.m_flGravity).

player = PlayerEntity(1)

UnicodeDecodeError when retrieving engine string that contains invalid bytes

It appears that this can happen in a number of places. Here are some easily reproducible situations:

from commands.say import SayFilter
from events import Event
from players.helpers import playerinfo_from_userid

@SayFilter
def say_filter(playerinfo, teamonly, command):
    command.get_arg_string()

@Event
def player_changename(event):
    event.get_string('newname')

@Event
def player_activate(event):
    playerinfo = playerinfo_from_userid(event.get_int('userid'))
    playerinfo.get_name()

Running the above example, the following steps will raise a UnicodeEncodeError:

VGUIMenu issues

This was first reported here.

So, I did some testing, and it seems there are a few issues. First, in this line, if you pass any more than 2 parameters, since we have "length" set to 2, only 2 parameters are iterated over, not all of them.

Also, in that same line, since we iterate over parameter_values, we are only iterating over the keys themselves and we never account for the values.

Also, we never seem to set the 'length'. I do see where we account for length. However, this seems to just be setting the length to 1 (and it never specifies "length", though I don't think we really have to on the OrangeBox). The length should be set to the number of subkeys.

Here is my test code:

from events import Event
from messages import VGUIMenu
from messages import SayText2
from players.helpers import index_from_userid


motd = VGUIMenu(name='info', show=True, subkeys={
    'title': 'GunGame Winner', 'type': '2',
    'msg': 'http://gungame.net/gg5_win.php?winningTeam=Terrorist',})

chat = SayText2(message='This is a test.')


@Event
def player_say(game_event):
    motd.send(index_from_userid(game_event.get_int('userid')))

    # Make sure I didn't break other messages with special parameters
    chat.send(index_from_userid(game_event.get_int('userid')))

Emit Sound does not work correctly (attenuation)

Hi Guys,

I noticed that the Emit sound function of SP isn't work correctly.

If i change attenuation > 0 it does not work. No Sound gets played. But if its zero it works.

Tried this:

cheer = Sound((), SOUND_FROM_WORLD, "source-python/zombiemod/fz_scream1.mp3", volume= 0.6, attenuation = 0.9)

also this

cheer = Sound((), SOUND_FROM_LOCAL_PLAYER, "source-python/zombiemod/fz_scream1.mp3", volume= 1.0 , attenuation = 0.9)

I want to play a sound from a Player but the volume should be set by distance to the Player.

Like ES did:

es.emitsound('player', userid, sound, 1.0, 0.9) # 1.0 = Volume , 0,9 attenuation

Thanks :)

menus.PagedMenu() idea of "back" option

It would be really nice if we could bind the "Back"-button in the first page of a PagedMenu() manually in our scripts. Example script of how it could look in usage:

def some_menu(index):
    menu = SimpleMenu()
    menu.append(SimpleOption(1, "some other menu", 1)
    menu.select_callback = some_menu_callback
    menu.send(index)

def some_menu_callback(menu, index, option):
    if option.value == 1:
        some_other_menu(index)

def some_other_menu(index):
    # create a paged menu with 2 pages
    menu = PagedMenu()
    for x in range(1, 10):
        menu.append(PagedOption(x, x))

    # this would tell the PagedMenu that we want to bind the "Back"-button on the first page on ourselves
    # the argument is what would be passed as option.value in the callback
    menu.add_back_option('go_back')

    menu.select_callback = some_other_menu_callback
    menu.send(index)

def some_other_menu_callback(menu, index, option):
    if option.value == "go_back":
        # would be only called if we are in the first page of the menu, otherwise behave normally
        return some_menu(index)

    print(option.value)

Might not be the best way to do this, but it's just an idea so you know what I mean.

NullPointers with several wraps

Several wraps may use a null pointer internally; thus causing a server crash when trying to call member functions.

This can probably happen for more wraps then the examples, and this is an problem that should be fixed as a whole when wrapping the game's interfaces.

It should either mimic the behaviour and simply return a python None object, so you can work with a nonetype error, or raise a python exception or so.
As an extend, this also becomes problem if a pointer becomes null for some reason, in the original SP write this wasn't as much of an issue, as it would be simply none then, but since all the methods are abstracted, it might just crash when trying to call member functions.

CPlayerInfo
player_connect: IPlayerInfo does not work so early on, i.e. the object returned is NULL, but you can create an instance of CPlayerInfo, and once you call any member function the server crashes

CNetChannelInfo
-> INetChanneInfo returns NULL for bots, so if you use it on bots, server will crash

PlayerEntity "cash" error

If you change the player's cash. The cash attribute doesn't update when they gain cash due to round start or on player kill. The value just stays at whatever it was set at.

PlayerWeapons class issues in CSGO

I was playing around with setting the clips/ammo of weapons and when setting the clip of weapon_knife, I'm getting this error:

PlayerEntity(1).set_ammo('weapon_knife', 1)

  File '..\addons\source-python\packages\source-python\players\weapons\__init__.py', line 117, in set_ammo
    self._set_weapon_ammo(value, classname)
  File '..\addons\source-python\packages\source-python\players\weapons\__init__.py', line 150, in _set_weapon_ammo
    weapon_manager.ammoprop + '%03d' % weapon.ammoprop, value)
  File '..\addons\source-python\packages\source-python\entities\entity.py', line 434, in set_property_int
    self._set_property(name, 'int', value)
  File '..\addons\source-python\packages\source-python\entities\entity.py', line 502, in _set_property
    name, self.classname))

ValueError: Property 'm_iAmmo.-01' not found for entity type 'player'

Furthermore I found a weird behaviour when setting the ammo of other weapons. For example, I've set the ammo of weapon_awp to 10, and after I reloaded the gun it resetted back to it's previous value, before I set it in my script.

Test script:

from events import Event

from players.entity import PlayerEntity
from players.helpers import index_from_userid

@Event
def player_jump(game_event):
    userid = game_event.get_int('userid')
    index = index_from_userid(userid)
    player = PlayerEntity(index)
    player.set_ammo('weapon_awp', 10)

If you test this, jump, then shoot once or more, then reload. Ammo will set back to the value it had before setting it.

EDIT
First bug can be ignored, as answered by satoon.
Second bug was just a temporary game bug, I had sv_inifinite_ammo set to 1 before I tested this, setting it back to 0 created this weird behavior. I restarted my server with default value 0 and it worked fine.
And by doing this, I discovered another bug: For example, if I manually set the ammo to 10, then shoot 10 times and reload, I should have now 0 ammo. But instead the game sets it back to the default value (awp 30).

And this bug still exists:
Setting the ammo to 0 does nothing.

PlayerEntity.set_model causes AttributeError

I'm using the May 21, 2015 release

Edit: I should also mention that it's orangebox/css.

Whenever I want to set a player's model to another one, it raises an AttributeError:

File '../addons/source-python/packages/source-python/menus/radio.py', line 343, in _select 
    return super(PagedRadioMenu, self)._select(player_index, choice_index) 
  File '../addons/source-python/packages/source-python/menus/radio.py', line 97, in _select 
    self._player_pages[player_index].options[choice_index]) 
  File '../addons/source-python/packages/source-python/menus/base.py', line 124, in _select 
    return self.select_callback(self, player_index, choice_index) 
  File '../addons/source-python/plugins/seekme/models.py', line 48, in model_menu_callback 
    player.model = option.value 
  File '../addons/source-python/packages/source-python/entities/entity.py', line 118, in __setattr__ 
    super(Entity, self).__setattr__(attr, value) 
  File '../addons/source-python/packages/source-python/entities/entity.py', line 335, in set_model 
    self.edict.set_model_index(model.index) 

AttributeError: 'Edict' object has no attribute 'set_model_index' 

The model's index definitely exists because it's a server-side model and has been instantiated with engines.prechache.Model.

Code which handles setting the player's model:
https://github.com/backraw/seekme/blob/master/addons/source-python/plugins/seekme/models.py#L48

Code which instantiates the model:
https://github.com/backraw/seekme/blob/master/addons/source-python/plugins/seekme/models.py#L99

PagedMenu select_callback raises AttributeError

This code:

from players.entity import PlayerEntity

player_models = dict()


def menu_callback(menu, index, option):
    """Called by a player selecting an option from the Models menu."""
    # Get a PlayerEntity instance
    player = PlayerEntity(index)

    # Tell what's happened
    player.say('model changed to {0}'.format(option.value.name))

    # Save what has been chosen
    player_models[player.userid] = option.value

    # Is the player alive and on a team?
    if not player.isdead and not player.dead_flag and player.team > 1:

        # If yes, change their model to the one chosen
        player.model = option.value.path


class _Models(dict):

    """Extends dict to map models to Model instances by their basenames."""

    def __init__(self):
        """Called on instantiation."""
        # Call dict's constructor
        super(_Models, self).__init__()

        # Create a PagedMenu instance
        self._menu = PagedMenu(
            select_callback=menu_callback,
            title='{0}: Models'.format(info.name),
            description='Choose a model below.'
        )

        # .........

raises the error as soon as I choose the first option I get when the menu is sent to me.

PlayerEntity.run_command & BotCmd bug

I tried hooking run_command in CSGO and came up with an issue.
The attributes in BotCmd are not working or are mixed. What should be BotCmd.buttons is actually BotCmd.weaponsubtype. The most attributes are not giving correct values.

import memory

from entities.hooks import EntityPreHook
from entities.hooks import EntityCondition
from entities.helpers import index_from_pointer

from players.bots import BotCmd
from players.entity import PlayerEntity

@EntityPreHook(EntityCondition.is_player, 'run_command')
def pre_player_run_command(args):
    index = index_from_pointer(args[0])
    cmd = memory.make_object(BotCmd, args[1])
    player = PlayerEntity(index)
    print(cmd.weaponsubtype)

Warnings printing more than once

Using warnings.warn should only show the first time a specific warning is given. However, each warning currently shows every time it is called.

I tested this prior to the new hooks.warnings.WarningHooks implementation and saw the exact same result. Doing the same thing in IDLE on both Python 3.4 and even back on 2.7 only show each warning once, as it should.

Test script:

import warnings
warnings.warn('This is a test')
warnings.warn('This is another test')
warnings.warn('This is a test')

PlayerEntity (BaseEntity) doesn't update itself

If you save PlayerEntity of some player (BaseEntity of some entity), then all it's properties will not be updated if something "outside" will change them. Before recent entities update it works fine...

Here is a simple plugin, which gives player 100HP when he uses a game chat:

from events import Event
from players.entity import PlayerEntity

player = None

@Event
def player_say(event):
    global player

    if player is None:
        player = PlayerEntity(index_from_userid(event.get_int('userid')))

    player.health += 100

Let's say player got 300HP (in total) and died, but then when he will use the chat dor only one time after respawn, he will recieve 400HP in total (300 that he got before death + 100 new) instead of 200HP (100 from spawn + 100 new). Same for all other properties (tested with speed, gravity and cash).

CS:GO Protobuf crashes

See http://www.sourcepython.com/showthread.php?542-%28protobuf-%29-messages-crashes

Apparent memory leak in output listener manager

This one was a little tricky to track down. It seems to only happen (or at least with a much higher rate) on maps with func_tracktrain. Memory usage will steadily increase with at least one player connected to the server (tested in CS:S and TF2 on Debian).

It's possible to reproduce on this map: http://files.gamebanana.com/maps/surf_fast.7z

Commenting out this line seems to stop the leak: https://github.com/Source-Python-Dev-Team/Source.Python/blob/master/addons/source-python/packages/source-python/listeners/_entity_output.py#L40

ValueError in PlayerIter when server is full

I was able to reproduce this in CS:S and TF2 on Debian. September 14 2015 build.

To reproduce:

• Run SRCDS with +maxplayers 2
• Get someone else to join the server
• Load this test plugin:

from filters.players import PlayerIter

def load():
    for x in PlayerIter(return_types='userid'):
        pass

[SP] Caught an Exception:
Traceback (most recent call last):
  File '../addons/source-python/packages/source-python/plugins/manager.py', line 78, in __missing__
    instance.globals['load']()
  File '../addons/source-python/plugins/sandbox/sandbox.py', line 4, in load
    for x in PlayerIter(return_types='userid'):
  File '../addons/source-python/packages/source-python/filters/iterator.py', line 48, in __iter__
    yield self.manager._return_types[self.return_types](item)

ValueError: Unable to get a UserID from the given Edict instance (eab43058).

Add iterators for server, say and client commands

This will also give you the ability to check if a command already exists.

Gravity not resetting

PlayerEntity.gravity attribute's value is not resetting on player death or round end (needs to be reset to 1.0 manually on spawn to avoid stacking gravity values).

Downloadables error on plugin_load

Loading a plugin via the autoexec that contains a Downloadables instance, causes an error, since string_tables.downloadables returns None.

Add the ability to get command line arguments

I could definitely use the ability to get the command lines options, similar to: https://sm.alliedmods.net/new-api/commandline. Seems incredibly easy to add, preferably accessible through the standard sys.argv so that libraries like argparse work correctly.

mathlib's Vector.normalize() returns false result

I am getting the exact same result as Vector.get_length() (a float), but it should return a Vector, like this:

def normalize_vector(vec):
    x, y, z = tuple(vec)
    length = vec.get_lenght()
    return Vector(x / length, y / length, z / length)
