Summary0002956: A_Wander online desync
DescriptionA_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

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".
