[MBF21] A_MonsterProjectile 'hoffset' oddity?

[SavebearingBoss]

Using "A_MonsterProjectile(PlasmaBall, 0.0, 0.0, 10.0, 0.0)" should make the monster fire a plasma ball from the side but the projectile spawns in front of it instead. Is that intended behavior? If so, is there a way to get a proper left/right offset?

It should spawn to the side (I never learned left or right) though 10 isn't a lot of distance so it might not be noticable. MonsterProjectile doesn't have forward offset at all.

Never heard of "A_MonsterProjectile" before.

Maybe you mean to use A_SpawnProjectile? 

You are probably thinking of DECORATE or zScript instead of MBF21.

It's because the values are in fixed point. You have to multiply the value you want by 65536. So the 'correct' value for 10 would be 655360. Passing 10 would make the offset 0.000152587890625 to the left.

From the context, I'm assuming Decohack utility is used, so it's not really the case.

Like I said before, 10 units isn't very much, it might be a good idea to have 2 projectiles one with positive and one with negative effect fire simultaneously, see if they fly side by side.

I downloaded DSDA-Doom and tested my wad there, and it works as intended - spawning two projectiles (one with positive offset, one w/ negative), both appear side-by-side rather than one in front of the other, so I guess GZDoom's implementation of A_MonsterProjectile is bugged as of version 4.11.3.

If there's something broken in GZDoom, it's best to leave a bug report so it gets fixed.

I've tried to post but I just get "The solution you provided was incorrect." I've tried disabling uBlock Origin, to no avail.
