Summary

0003272: Error message appears in Multiplayer due to a looping projectile

Description

During a multiplayer game when a projectile uses a user_x based condition for limiting a looping state a error message appears:
"Warning: Breaking infinite loop in actor LauncherGasGrenade.
Current offset from spawn state is 11"

The error message does not appear all the time so it takes a while for it to show up, also no gameplay breaking bug happens as in the game will continue normally despite the error message. I tried changing the Projectile actor a few times to fix it somehow but all it does is that the number reported is not very large anymore.

Offending actor: LauncherGasGrenade

Steps To Reproduce

1. Load the loopingbug.pk3 mod
2. Host a server and connect to it
3. Keep firing till the error message appears

Notes
(0018360) Dusk (developer) 2017-09-23 16:46	The client doesn't predict the A_JumpIf call so it assumes it to not jump until the server instructs the client otherwise. So the client can get stuck in the loop. This is not a bug but rather an unfortunate limitation of the client-side prediction involved. Since the GasCloud actor appears to be decorative, I suggest to split the gas-spawning code into a new CLIENTSIDEONLY actor. That way there's no networking involved in the loop and it should work fine.
