this is how I used particles in a Space Invaders clone
_InitBaddieParticles:
make particles 2,1,25,2
color particles 2, 255, 200, 200
set particle emissions 2, 10
set particle speed 2, 0.1
set particle gravity 2, 10
hide particles 2
Return
the image file in the Make Particles (2nd Argument) is just a blank white bitmap loaded in dbp with Load Image, and designated as image 1
then I used Show Particles 2 whenever a baddie got shot, then hid them again with Hide Particles 2 and some timer() stuff to not halt main loop for particle display
hope this helps
