What did you try? I could help get it working. It doesn't look like it needs a lot of customizability, but maybe a frequency option (args[0] in the chance property in A_SpawnItemEx. The higher the first argument is, the lower the frequency of the bubbles).

The plan was to allow the mapper to set the frequency of bubbles spawned, the extent of the area in which they are spawned, and the speed at which they are 'shot' upwards. I stumbled on a problem though, the values I would enter in Doombuilder were not having the same effect as if the same values were 'hardcoded' into the Decorate lump. I was tired so I gave up.

If you can get it working feel free, it can be a joint-entry

Oh, and I noticed strangely that with additive or translucent rendering, the bubbles always remain grey despite being in a coloured sector which looks odd. Dunno why it does this. Gez's HPack foggy projectile fix?

Nah, I won't claim credit for just fixing something like this. You already had the idea to do it anyway.

Did you use the existing spawners on the SFX Shoppe as an example when you tried?

Edit: By the way, the warping REALLY bogs down my machine, for some reason.

Well I might as well make a suggestion at least. Going back to one of my older post, one of my ideas, and I think the only SFX idea I have ever had, how about a "tornado" Make it so that you can change the speed of which it travels, how strong the winds are, and how much damage it deals if you get sucked in. Maybe also have some twigs and leaves and stuff blowing around that can also hurt you or something.

sfx that harms the player doesn't really seem like a good idea imo.
You could make a dust-devil though, like those in Fallout3.

I don't know, I was considering making a spawner of those Quake 1 lavaball things.

True dat.

I made a similar thing for Super Mario Deathmatch

Yet another! I'll probably do the aforementioned Quake 1 lavaball, too, but that's it.

Well maybe have two different types? One that just pushes you around and stuff and the other have it harm the player. At least then you give the player the choice of having one or the other. Has the same functions to each but one deals damage while the other doesn't is all.

A tornado is not something easy to make. Atleast not on the epic scale i tried to do it in. But theres been a lot of cool features added to zdoom latley that would help this quite a lot, I might give this a shot actually.
