spelunky-psp's Issues

Android PPSSPP: could not find executable

PPSSPP v1.15.4
spelunky-psp v0.5 (*.pbp)

Pick up the closest item, not some "first in order"

In this situation, I cannot pick up a rock if there's a flare in range. In HD, at least, you would pick up the closest item, and only resort to random order if their coordinates are the same.

(Configuration?) option to use HD/HD 2 keymappings

Some players (most fans, I believe) already got used to HD or 2 keymapping. It makes sense to give them the option to use it.

Building for PSP failes upon linking libSDL_mixed

I'm trying to usepspdev/pspdev:latest docker image to build the project, this includes the psp toolchain required in the building instructions. The image, along with the psp toolchain is based upon alpine linux, however I get linking errors when calling ./scripts/build-psp.sh.

[100%] Linking CXX executable Spelunky_PSP

gmake: *** [Makefile:136: all] Error 2

It looks like alpine doesn't define sigprocmask, waitpid functions used in libSDL_mixer. What can I do with this and how this is supposed to be built? I have no idea, since switching to any other linux distributive would be a very time-consuming task as it requires to recursively modify all the images used in the pspdev build.

Tutorial area?

Hi, on PSP version, the start screen shows a tutorial area but I can’t access it.

Cannot climb to the very top of the ladder

This is the highest I could climb.
The player must be able to climb to the very top (and then walk to a side).

Crawling from a cliff should leave the player hanging from it

It's a critical mechanic that allows for more precise control.

Configuration file or arguments for certain parameters

I'd love to tune the music volume. On my hardware, even the lowest global volume setting is too loud when the program is at 100% volume.

Spawn location should be safe

Before a character takes a single step, they should not be attacked by mobs or traps.
I got a bat and a skeleton on me right off the bat.

Player should not be able to cling in this position

Putting down an item immediately picks up another one with the same keystroke

Reproduced on a flare and a rock.

Whip hitbox

I was able to whip a bat behind my back and a spider that was falling on me from the top (in the second case, I was standing half a tile away from spider's tile). IIRC, it's not possible in the original.
I might be biased, though, as I play a lot of HD recently.

Player falls when walking (or pressing Down) on top of a ladder

Instead, ladder should count as a platform for the purpose of walking sideways.
When pressing Down, the PC should cling and climb down, not drop all the way down.

Display a level seed

Jupiter Hell does a great diagnostic thing: they have a deterministic level generator, which depends on a single random seed.
Thus, in order to report a level generation problem, one only has to tell the level name and its seed number.

Migrate SDL_mixer to SDL2_mixer

The mixer library is still on SDL1 version.

Jumping while holding Down from ladders and from cliff-hanging should drop directly down

Now, the PC jumps 1 block up anyway.

This is an important technique that lets the player reduce the height of a fall and evade losing a hit point.

Hotkey to cancel the current wielded item

Original Spelunky had a C key rotate the wielded item through: bomb, rope, nothing.
Now, I cannot stop wielding a bomb if I mistakenly took it.

Building gets stuck while compiling AudioBank.cpp (Linux aarch64)

I'm trying to build Spelunky-PSP on Linux aarch64
My OS is Fedora 34 AArch64
My CPU is RK3399 (6 cores ARM 64 bits) and have 4 GB of RAM

I have followed the instructions, running first ./scripts/config-linux.sh, and then ./scripts/build-linux.sh

Building process starts fast, but then gets stuck on 20%, after:

[ 20%] Linking CXX static library libCollisions.a
[ 20%] Built target Collisions

It stays there for hours without making any progress. One of the CPU cores stays working at 100% while the other ones are not doing any hard work.

On the system monitor I see the process cc1plus (gcc c++ compiler?) is the one using 100% of one core and 1.3 GB of RAM. After examining it's command line I see it's trying to compile src/audio/src/AudioBank.cpp. When viewing it's opened files, the last one is 'src/audio/include/generated/title.wav.hpp', which is a 13MB source file containing raw data in the form of a char array.

It has been there by 5 hours without making any progress.

Maybe 13 MB is too heavy for being parsed and compiled by g++? Is there any way to import the WAV binary files without compiling them as sources? I know in some ASM dialects there is an incbin command which just import a a binary raw file, but I don't know if c++ has something similar.

SDL2 desktop port

This project is such a great news, thank you for all your work!
I looked into building it on Mac. SDL1 is holding me back, as it is known to be broken on the latest MacOS.
SDL2 would be great to have.

PSP issues

I ran the game on my PSP 1000. Here are some issues I had, maybe you will find it useful to know about them:

• Music doesn't loop
• Can't throw items upwards (probably because the same input is for opening chests)
• There is no way of cycling through items afaik, so they can't be put away (once you take out a bomb/rope, you have to throw it)
• A chest glitched into a ceiling when being put down; they generally don't have gravity when put down
• I also had the whole console reboot after putting it to sleep with the game running
• Taking the golden idol didn't trigger the boulder trap
• I was able to blow up a part of the menu 😝

Input documentation would be nice, I wrote down what I was able to figure out:

• Dpad to move
• Circle to crouch (why isn't Dpad down used for this?)
• Hold L to sprint
• R is action (also whip or throw item in hand)
• Square to equip a rope
• Triangle to equip a bomb
  Usual Spelunky input combos apply (e.g. crouch+action to pick up items).

Asides from that, amazing job, it's very nice to have this game on a PSP, and in such a small file size too 😁

Pressing "Action" on a ladder should not drop the player down

It should whip/use carried item and leave the player where they were.

Freeze in damage resolution

Sorry, cannot post a text call stack.
This was a complicated situation involving a bat, a skeleton and a bomb.

Walking into a 1-high block and jumping leaves PC hanging on it

It should let you jump on top of it instead. Only 2 tiles high walls should leave the player clinging.

This will delay the player when running away from monsters.

Android: cropped and no controls

And controls don't work (no touch controls visible, no Bluetooth gamepad response).
