| Summary | 0002956: A_Wander online desync |
| Description | A_Wander causes a lot of jittery movement and warping, especially when compared to A_Chase, I'm not sure if this is because of an actual desync, or an error in the movement interpolation. On a side note, when A_Wander is first called, the actor will walk in place for a few seconds. This has been reproduced in 3.0 r161030-2038 |

Provided an example wad. All monster defintions are from ZDoom wiki, with all instances of A_Chase insisted with A_Wander. On a side note, this occurred when testing a mod of mine online with a friend, and I used A_Wander for a subsitute of A_Chase to compensate for the same functionality, but without the missile chance. He claims that he shot an enemy 3 times, and all his shots went through him. I believed him since I was coop-spying him and the enemy was moving erratically and warping. This was with hitscan, however, we haven't tested it with projectiles |

I use a lot A_Wander (half monster use it) in my mod from stable version till ZandroDev3.0-161030-2038linux-x86_64.
Linux zandronum 4.8.0-2-amd64 #1 SMP Debian 4.8.11-1 (2016-12-02) x86_64 GNU/Linux
Never had single problem with this.
Check your code 10x, probably some other thing cause this. |

Understood, but I'm certain of the desync after many tests online and offline. I've provided an example wad where all occurrences of A_Chase has been replaced with A_Wander. Since ZDoom intended A_Wander to function the same as A_Chase, putting it in place of base ZDoom code would be a perfect way to demonstrate proper use of the function |

I support this case. I dont know about problems with regular A_Wander, but I want to notice that using A_Wander through in items does not move the actor at the clientside, but moves it at the serverside, so the actor is "teleporting".
