Summary

0004031: Weapon desync when spectating

Description

Happens in 3.2 test version also.
Weapons that use an Inventory item and A_JumpIfInventory to jump to another state desync if the person spectating is not present when the player picks up the inventory item.

Steps To Reproduce

load and create a server:
Complex-Doom.v26a2.pk3
LCA-v1.5.9.6.pk3
randomons-v1.2.5.1.pk3
Have Client A join the server. Give "Demon Tech Devastator", give CommanderDevUpgrade in console window.
Have Client B join the server and spectate client A. He'll still see the sprites for Demon Tech Devastator.
Client B Give "Demon Tech Devastator", give CommanderDevUpgrade in console window.
Have Client A spectate Client B he will see the correct sprites.
If Client A reconnects he will see the wrong sprites when spectating.
Changing map will break it for both clients.

Additional Information

Not sure if this can be fixed due to the current net code and the way inventory items/weapons work.

(0022398) Mr. Satan (reporter) 2022-09-16 05:04 edited on: 2022-09-17 06:13	Uploaded WeaponDesyncTest.pk3 When upgraded, it uses RocketLauncher sprites and Beta BFG firing mode. Also A_FireOldBFG uses 40 ammo per shot instead of 1 which causes ammo amount to desync between players. In Console Use NewBFG900 Give BFGUpgrade
