Hi,

here is a hip file, please download it first.

I make some particles and replace them to debris(I used a ball here.), then use these balls to emit other particles which I wanna replace to sprite.

it should be exploded and fall down on floor, then stop emit sprites.

my problem is : what attribute should i make, it can call another node's attribute for kill the useless particles(which replaced by sprite.)?

I tried use add an attribute node and give it $TY value, and set it : if $TY is going to be 0, then const. birth rate =0. If not, the const. rate is 1000.). But it didnt work.
