How do I negatize the screen in DECORATE?

In DOOM when you got the Invulnerability or when you fired the sigil in strife, the all the colors on the screen would flip, as though in a film negative. Is there any way to replicate this effect in Decorate? (I apologize for all the "How do I" questions, but I think I may have bit off more than I can swallow with this wad)

Involves palette shifting, not a straight inversion. So this is a really good request! Perhaps if we could set up any palette shifting, slow ramping, and so on, we could have Unreal-like weapon flashes. Happy happy fun.

For weapons you can use the A_LightInverse code pointer. But that's all that can be done so far (Unofficial build only!)

What does that do, internally? Does it actually do a true inversion of the palette, or the sector light level mapwide, or does it create a new palette based on an inversion of the original?

It uses a palette translation. No new palette is loaded for this effect.

Less complicated, then, but requires more specific user input.

Seems like it might be more open-ended, though.

WHat are the parameters for A_LightInverse? I think it's just duration in tics.

D'oh. Critical misunderstanding on my part.

None. It's like A_Light1 etc. and has to be reset explicitly by calling A_Light0.
