Combining projectiles?

    MISL C 6 bright

    stop
   
}

Okay...this idea is to make projectiles that kill each other and spawn another projectile in the direction of the second projectile (the one that is fired into the first one) for more powerful or defensive effects. Players (and monsters) could time their attacks and produce powerful combination moves, not unlike Chrono Trigger techniques.

I am having problems with the new projectile unpredictably spawning or not spawning at all. This is my original iteration of my code.

[Ivan]

Try to give the death state 1 tic delay instead of 0. Also, I think it will fail to spawn it right with the original missile's pitch, which I guess will require ACS for you to do it properly at the moment. (SXF_Transferpointers would be good to have here !)

[Ijon Tichy]

Try SXF_NOCHECKPOSITION with A_SpawnItemEx, and +PUFFGETSOWNER on the new projectile. It's not documented, but +PUFFGETSOWNER works with projectiles spawned through A_SpawnItemEx. It's also probably not supposed to work like that, but hey.

Okay..this one is goofy, I know..but the superimpball doesn't spawn at all, even with A_Explode. I'm positively stumped here. The only thing I can think of is that the projectile just plain doesn't use custom death states. I will try a roundabout code.

[Ivan]

Why aren't you using inheritance for your doom imp ball ?

[Spottswoode]

For this particular case, it doesn't make any noticeable difference.

[Ivan]

Well, I really haven't played around with custom death states for projectiles, so I don't really know if it should work in first place. Inheritance was the only thing that came to mind. Try inheriting from BaronBall instead?

[Spottswoode]

Also doesn't make a substantial difference. http://www.youtube.com/watch?v=BdDDKSaQ ... e=youtu.be This is the end result. The projectile is set to explode when it dies, so it should be killing the other ball.

[Ivan]

You know it might just as well be a bug right ? Do you know if it actually goes to the death.imp state ? Try renaming your damagetype maybe ?

Okay...after some more testing the damage type does not spawn the new projectile. Also apparently colliding any other projectile against the fireball causes it to phase through actors until it hits the wall...however with this code..two fireball projectiles die at the same time. This probably has something to do with the internal collision code in regard to projectiles. I could probably work around this by making the projectile a monster and giving it custom death states that way.
Edit: Apparently it was a bug of some type.

Edit: Apparently it was a bug of some type.

Does this mean the issue is resolved now?

[Spottswoode]

I'm fairly sure. Reported it to Graf and he said didn't have the problem with his current update.

It is a Zdoom bug...so it's resolved for the time being.

Thank you for your time Torr.
