Moddio is a Multiplayer-First Game Engine. It has a built-in server-authoritative netcode, including snapshot interpolation and client-side reconciliation. It can support 50+ concurrent players or 300+ moving entities hosted on a $5/month VM. Join us on Discord

Running the game

Make sure you have Node 16 or later. First, setup the repo

git clone https://github.com/moddio/moddio2.git
cd moddio2
npm install
npm run tsc

Then, to start the server run:

npm run server

You can now play the game at http://localhost:8080

How do I create a new game from scratch?

Moddio games are created & edited using Moddio Game Editor available at https://www.modd.io. To learn how to use the game editor, visit https://learn.modd.io.

After creating your game, you can export the game.json file for use in your local installation. To do this, navigate to Menu in the Moddio Game Editor and click Export Game.

Next, rename the downloaded Game JSON file to game.json and move it into the src directory.

To load your game file, simply start the server by running:

npm run server

You will be presented with a dropdown menu, where you can use the arrow keys to select your game file. Alternatively, you can pre-select your game file by running:

npm run server --game=game.json

moddio2's Issues

add projectile type comparison

hideChat and showChat features

Hides the chat box or shows the chat box

Hidden units display chat bubble

Even if a unit is hidden to other units, the chat bubble from it still shows to everyone

Command unit to move not working with CSP

ai units' facing angles are not updating unless they move

prize

The prize is no longer working like it isn't giving modd coins anymore, idk if it was a limited time event or what but either way nobody is receiving modd coins anymore even though I was receiving modd coins some hours ago

Visual bug: "<=" in comparators renders wrong

while (( number of units of Box )) <= style="color:blue">10</=>)
should render as
while (( number of units of Box )) <= 10)

make sure same is the case for if, for etc.

deleting game does not shut down servers of that game

I deleted a game and i was ingame, but it didn't unpublish the server, it stayed open

new action: "convert [number] to large number notation" (returns string)

uses the same code as "prettify leaderboard" in game UI settings takes a number input and returns it as string like 4.01K or 6.90M

undo button not working in ingame map editor

I filled in everything on the wall layer on accident and was unable to undo it

Set entity variable loads previous content and cant be changed

When you open the interaction window from the 'set entity variable' script it loads the previous content if you used it before.
On reopening that script the setter value can't be selected/changed.
Reloading the page solves that issue temporarily until a second 'set entity variable' script is created again.

entity width/ height returns undefined

getting an entity width or height via script returns as undefined

Item description attribute doesn't update

The item's description doesn't update the attributes it displays unless something else calls an update

add transparency, hue, saturation, brightness for units, projectiles, entities; more

if a player is experiencing less than 15 fps for over 5 seconds consistently, then suggest them to use canvas rendering instead (prompt a window)

action for "draw a line between <position> and <position> colored with <color> for <player>"

Pay to win bug

Dialogue Softlock

editing a dialogue's option's following dialogue and then pressing that option without republishing softlocks you

Minimal Repro:
add dialogue 2 as an option for dialogue 1. Press E to open dialogue 1
https://www.modd.io/play/HMTE9k9yM/
Game JSON:
https://mega.nz/file/uQE0XSAa#65h39d7xmhJ-xui0W69a7wT8XUiWQ3B8qSmKh-47CMk

Camera moved in map mode

The function to make a player's camera look at a specific place still moves the camera while in the map editor (i assume other editors too, like entity editor, etc)

gun is not shooting projectile if only one bullet left with CSP

only happens when "ignore server-streamed fire event" is false

add changeProjectileType feature

Chat doesn't work properly on standalone

it seems like the latest chat update caused some issues with the chat when hosting the game locally

projectiles are not destroying on wall contact

The projectiles are sometimes not getting destroyed upon wall contact.
example game: https://www.modd.io/play/dZoXA2DPe

Glitch outside game map

It’s possible to glitch outside of the map if you teleport out of it, and you will be able to stay in the void until you move, and when you move you will be pushed back into the map

Messages not being shown when multiple are sent at once

when multiple chat messages are sent at once only the latest seems to be displayed.

Error in 'send post request' causes script to stop

https://github.com/moddio/taro2/blob/7dfb0b98bdf44194421a446ef8e26ea6d0e1ff57/src/gameClasses/components/script/ActionComponent.js#L226-L231
Failure to parse the object results in the rest of the script's execution within that block to be broken. Additionally, no error is logged in the dev console making debugging very difficult.
Minimal game for example: https://www.modd.io/play/2dCYCmUVW/

Select item crashs the game

When i select a item in any slot, my game crashs, this only happens when i press the number of the slot
(Example: if i press [4] Kebind to select the slot 4, if that slot has a item, the game crashs only for me)
This is the console when this bug happens

Also i can't use the mouse cursor to select a slot with a item

Custom input on top of menu

Custom input appearing on top of menu

Gravity does not work with CSP disabled on Planck physics

Make sure gravity works on all physics engines.

fix: hide <unit> from <player type>

Needs more bug documentation.

Projectile created with OnDestroy effect is spawned at source position

minimal repro: https://www.modd.io/play/W0iZK8pFM

throw grenade, wait for it to explode. The explosion will be rendered at origin point of the throw instead of the destruction point.

Physics Engine: PlanckJS (Less Performant, but stable)
Client Physics Engine: Box2Dweb (Performant, but has memory leak issues)
Client-side predicted movement : No

getPingOfPlayer feature

Returns the ping of the provided player

add setVolumeForPlayer feature

Could be for specific sounds or for everything

Join glitch

Theres a problem it wont let me join any games and idk why?
Can y’all try and fix it.

Tiledsheet bug and map button bugged

When I join any game, I see the game tiledsheet on the left of my screen.
Also, when I press the map button (when I’m making a game)
my whole Ui dissapears…

This is a example of the tiledsheet bug...

This is the console thing...

Dont forget that when i press the map button my whole Ui dissapears!

Pick tile triggering at wrong time

In the ingame editor if holding right click and then pressing the middle mouse button (scroll wheel) it will select the tile as if you stopped pressing the right click button

Chat: change server text color feature

Make it so you can set the default color of text sent by the server instead of making it always yellow, and also allow specific messages to have different colors

send current animation of units to new players joining game

issue: new players joining see the 0th frame despite the current animation of a unit being not 0

create a test game first which has an NPC unit with a non-0th index animation frame set. me joining the game should display the correct, non-0th frame.

new trigger “when this entity enters a unit’s sensor”

not to confuse with docs/triggers/unitEntersSensor

changing scripts in json view doesn't update code

Changing scripts while in the json view of a script does not update the code shown on screen

Creating game starts with plays

When creating a game it doesn't have 0 plays but usually starts with 2

floating text has no chat filter

remove rubberbanding for teleporting units

https://www.reddit.com/r/explainlikeimfive/comments/22dv4n/eli5_bf4_and_rubber_banding_also_net_code/

instead of instantly teleporting to the new position, units are moved there. This causes them 'fly' over the screen.

Cancel making region broken

When making a new region in the ingame editor, while making a region if you click the cancel button it won’t actually cancel anything it will just create the region anyway. This is the same if you press the X and exit out of the region, it shouldn’t create it if you do that.
