Open Source, multiplayer 2D shooter made in Godot

Project FreeGUN

Project FreeGUN is a FOSS 2D shooter made in the Godot Engine. Everything in the game is free and open source; the code, art assests, etc. The goal of the project is to be a framework to be built upon for other games. The game is built around mouse and keyboard controls, and should work on Windows, Linux, and macOS.

project-freegun's Issues

Incorrect synchronization of bullet/gun between peers in multiplayer

Game-breaking Bug 👎 :

In multiplayer whenever a peer's (say, Player1's) ammo is depleted and he/she switches to gun0 (initial gun w/ infinite ammo) via the gun1 button ("1"), the other peer (say, Player2) does not register the weapon switch and no bullets of Player1 are instanced in Player2's game, effectively making Player2 invincible. The same occurs vice-versa - (Player1) becomes invincible, but the difference is that on Player1's game client the bullets of Player1's gun are not instanced/visible when Player1 shoots but, on Player2's client the bullet's can be seen emerging from Player1's gun and Player2 can be damaged and can die from them.

How to recreate the bug:-

1. Start 2 instances of the same game on the same LAN.
2. Start a normal "multiplayer" match.
3. Any one player (say, Player1) should pick a limited-ammo gun pickup (say, gun1 w/ ammo = 5).
4. Player1 should deplete all his ammo of gun1 to zero
5. THEN Player1 should switch to the initial gun (gun0 having infinite ammo) and SHOOT THE GUN normally
6. Notice Player1 on Player2's client, Player1 is not shooting ANYTHING

Therefore there's an error in multiplayer sync which causes gun of enemy peer to not shoot OR his bullets not to be instanced (idk which) AFTER he switches from a depleted gun to the infinite gun.

Dev plz fix @devmcclu
