Enemy projectiles not spawning

[OmDr]

I'm having a strange issue;
A custom monster will sometimes fail to create missiles during its missile state, despite the sound and animation going through.
This is the monster:

And this is the Missile:

This issue does not occur on vanilla maps (when summoned or spawned), and only seems to affect custom maps (both maps I did and didn't create). Would anyone know what I am doing wrong?

only seems to affect custom maps

If that's the case, then uploading a test WAD which demonstrates the problem would be a good idea, as it's easier to debug that way.

Ok, I have uploaded an example .wad here

There are two monsters to test it on: one you'll see when you start, and another down on the lower floor. I may have put it on a bad spot, so if the upper one gets stuck you'll have to find the lower one.
Watch the monster shoot at you for a little bit, you'll start to notice it doing the animation but no attack happening.

After some fiddling around, the issue seems to be these two lines:

Code: Select all

TROO A 0 Thing_Hate(1,3,3)

TROO G 6 A_MonsterRefire(130, "See")

Commenting out either of those let the monster behave normally.
The monster seems to be acting like it has two targets at once due to Thing_Hate, so A_MonsterRefire is checking sight for a non-existant target and causing the monster to stop attacking. For some reason this is making the monster further freak out and attempt to also attack the target that doesn't exist, thus spawning nothing. This sounds more like a bug than a mistake on your part.

Commenting out the thing_hate part does indeed let it function properly again. Frustrating, but it isn't required as long as they have QUICKTORETALIATE.
Thank you for your help.
