particles terrain

have you evere seen some destructable terrains made by particles? i tried to program it, but the program is too slow...
the code is very simple: some functions create particles, some other delete them and some other update them...
can anyone help me?

I think you may be talking about Voxels (Volumetric pixels)

thanks for the help, but i don't mean these terrains...
i mean 2D destructable terrains, that seem made by particles as a normal 2D particle effect.
View some examples:

They simply modify the image and allow the worms to go anywhere the image is "cleared". The particles are simply spawned where a hole is made.

thanks, but are you sure the terrain is just an image?
in my second example there is gravity for each image's pixel and it behave as made by particles...

That's the way the old worms where made. Although you could grab the pixels that are blown away and then insert them into a particle system if you where feeling frisky :)

I made a game like worms once where I had a scrolling background and then an image with 0 representing the color key (so the background showed through) and then when some of the image was blown away I simply filled it with 0. When moving my soldiers I simply tested the image for color 0 to see if they could move there. (Their bounding box that was).

Hope it helps.

Where can I find the game represented by the last screenshot? It looks cool :)

Hello.

Someone else posted about this kind of game recently. Search the fora for 'Scorch', 'Scorched Earth', 'Worms' and you should find something.

Goodbye.

thanks very much!



it's Atomic Cannon, from www.isotope244.com, ;D

i found it!
