Disappearing Gas?

Archive: 7 posts


Is there a way to make gas disappear? I have apart of a level where I want gas to disappear from the level so it becomes accessible.2008-11-21 06:08:00

i didn't try yet but maybe it's possible to turn dissolve material in to gas and then make it dissappear??2008-11-21 06:46:00

Edit: Apparently I need to do more research before talking.2008-11-21 13:14:00

In my experience, you cannot trigger dissolve material if it is turned into gas.

a) If you attempt to attach a switch to a gaseous dissolve material, it will refuse to attach.
b) If you attach a switch to a dissolve material and then make it gaseous, the line will turn "red" indicating that it will not activate, and it indeed does not activate.

Your best bet would be to use an emitter to create the gaseous material where you want it. Set it up so that the lifetime and frequency values are the same (you could set the frequency value a bit lower than the lifetime) and attach an inverted switch to it (so that the emitter is ON by default until whatever point you decide to want it turned off). Once your switch is activated, it may take some time before the gas disappears, so try not to set a lifetime too long.

Hope this helps

New here but hope I can be of use. Gas objects can pass through other objects. I've made a level where a 'block' of gas is stuck to a hidden motorised car, all you see as the player is a wall of gas advancing forcing you to move forward. The gas passes through the floor and platforms.
I'd imagine a similar system could work here. Attach the gas to a piston that pulls it out of the way when you need. I can't remember if you can attach a piston to gas so you may need to attach the gas to a sliver of glass and the piston to that (technically you'd do the attaching before you converted the material to gas).
Hope that makes sense.

this idea is great, its what i would do, except for one thing, i would put the emitter on a piece of dissolve material and a sensor switch to dissolve the material and the emitter so the gaseous cloud will vanish right when you need it to. unless the lifetime lasts even though the emitter is gone? not sure about that.

I questioned this on Oni's Volcano level - they have it set up so that your ballon has to be near the floor when you jump out, otherwise there is a black gas that kills you. They have there 2 sensors visible on the floor and one on the ballon, but how they did it exactly, I haven't been able to complrehend >.<2008-11-21 16:42:00
