edward850: if you can tell me what to change, I'll throw it in here.

Controls the fade out of each tic, basically. Internally it's usually set to 255/lifetime. Also I noticed you changed startalpha to fixed, but never changed what that means to P_SpawnParticle, which still takes a byte (because the particle internally takes a byte).

You completely forgot the ACS function.

As for fadestep, change ACTION_PARAM_INT(fadestep, 11) to a fixed and scale it just like startalpha. Perhaps the same should be done for the ACS function for consistency.

Uh, what?

Code: Select all

	BYTE startalpha = (BYTE)Scale(clamp(startalphaf, 0, FRACUNIT), 255, FRACUNIT);

Somehow I completely missed that despite looking right at it. Silly me.

Actually I specified it's for DECORATE only. The relativity is only for actors, and the ACS version has none to deal with. Just a set of coordinates.

Okay, doing that now. Not sure what to do for the ACS version though, for changing that.

I am completely off the ball this morning or something. Perhaps I shouldn't have changed my coffee...

I took a gander at the ACS version for changing the alpha and fadestep... No idea on how to handle those.

Let's put all future discussion here.
