Hi, everybody, i got a problem of goal.
The situation is that i would like to emit particles from a geometry, and then i wanna those particles goal to the postion of that geometry exactly the position when those particles created. Therefore, when i move this object, the particles can be attached to the object. I really got no idea to do this. anyone could give me some ideas, let said samplerInfo or expression can help? thank you!!

hey Yin.

Its pretty easy to set up. Make the emission surface a goal object. On the emitter, check on the Need Parent UV option (it is a few options below the emission rate).
Then add the following PP attributes: goalU, goalV, parentU,parentV (you can find them all in the particle tab of the particle's add attribute editor.

Then set those attributes as followed in a creation expression:

particleShape1.goalU = particleShape1.parentU;
particleShape1.goalV = particleShape1.parentV;


Good Luck!
