when i create a particle
use
particle -n particle1;

and

add runtime expression

vector $pos = position;
vector $vel = velocity/2;
emit -o particle1
-pos ($pos.x) ($pos.y) ($pos.z)
-at velocity -vv ($vel.x) ($vel.y) ($vel.z)

but not effect~

what's wrong

the script 's position wrong?

If you just create a particle node and add a runtime expression, nothing will happen because runtime expression is run for every existing particle. Since you probably didn't connect it to any emitter or use emit command before (MEL script) that would cause the creation of particles, no particles existed beforehard and thus expression didn't run once.

Note that if you already had particles, such runtime expression would double the number of particles every frame.
