Changing radiusPP
 

Hi there,

I have this simply excpression but i can't figure what's wrong:

Runtime Expression Before Dynamics mapped on radiusPP of my ParticleShape2 (blobby Surface)
here's :

float $raggio=.05;
if($raggio<.2)
{

$raggio=.05+(time/20);
particleShape2.radiusPP=$raggio;
}

i want my blobbies start from .05 size and grow up 'til .2 but in some case blobbies grow time after time without stopping in other case they won't grow. What's wrong? What's the correct implementation?
thnx

ok you need to do this first:

create a creation expression first (in the same way you made a runtime one) but do this:

//this is your start value
particleShape2.radiusPP == 0.05;

then change your runtime expression to something like this:

//get the value of the radiusPP
float $raggio = particleShape1.radiusPP;

//compare it to the max value you want them to grow to
if($raggio < 1)
{
//add a value on this can be anything you want it to be
$raggio+=0.001;
//set the value of the radiusPP
particleShape1.radiusPP=$raggio;
}

That should work.
