I try this but it dose not work.

+ Code Snippet

phy set emitter end color 1, rgb ( rnd ( 255 ), rnd ( 255 ), rnd ( 255 ) )

-Win XP SP3 -P4 3go/Ge Force 9600 GT driver 177.92
PhysX 08.09.04

Because the RGB commands are meant to be put separately in the command.

phy set emitter end color ID, red, green, blue

ok then red=rnd(255), green=rnd(255) ok. I was trying by that model.

Sorry for the double post
Thanks, I place the variable red=rnd(255)...

I want to make a change every 10 sec. Here is my codes so far, got some flahings.

Note: the fire.png can be found in the Dark Physic project folder
ProjectsDark PhysicsInformation
if you have the latest version of DP.

Thanks

Hi Random color object

Your timer code was setting the emitter color every time in the loop

here is some changed code, I set the timer to 1000 to see the change more frequently.
