So I got most of what I wanted in this particular room to work - mostly.
But there is one major problem I'm not sure how to solve, except to redesign the whole thing. And I don't want to redesign, I like this idea
So my problem is with the poison cloud spell - of course. It lasts too long, overlaps with itself and contains too many particles.
I want to gradually fill up a room with poison gas as if it was coming out of 2 demon heads. It starts out in 1-1 squares in front of the heads, then 2x2, 3x3 etc. A poison cloud lingers for about 10 seconds [btw, is there any documentation on exactly how long it lasts?] so I need to wait about 10 sec between spawns or they will overlap and lag badly. And that is a bit harmful for the tension I wanted to build :S
Is there anything to be done to reduce the duration of the spells (with a custom spell for example)? I searched the forums, but what I found looked pretty intimidating. Also can something be done about the particle effects? I know my laptop is kinda old, so maybe better PCs would lag less, but I don't want to rely on that.
There isn't anything about spell duration in the asset definitions. I have found the particle definition for poison_cloud but I wouldn't dare fiddling with it on my own.
If it would be too complicated, I guess I can re-work the spreading part and code it so new spawns wouldn't overlap with the old ones that still linger; and this way I could speed up the process of filling up the room. But I'd prefer not to...
