Emit for 3 Frames

[Strooja]

Hi Guys,

 

i have a question.how can i realize that 2 objects after collision emit particles for 3 frames and then stopped. i started with an if statment in the impulse activation but i cant use any attributes.Hope anybody can help me.

 

Many thanks in advance for your help.

Something like this will do the trick.

 

$F > 5 && $F < 8

 

That will only evaluate when both are true.

^^thank you,thats the simple way.The problem is i build an digital asset and  in every scene the collision is on a different frame.so i want detect the collision frame, start emit and 3 Frames later it should stop.

Hmm... so why you don't use something like this:

 

$FF > $COLLISION_FRAME && FF < ($COLLISION_FRAME+3)

 

or you can eg. use vex to modify active attribute.

mhm ok.But how can i create a global variable in a pop .I create a pop wrangle and  write :  addvariablename(1,"age","AGE");

 

and in a pop vop   Activation field  i write: if ($AGE>0.2,0,1)

 

thats for an other example but the same problem.It doesnt work.
