Maya mel script (particles attach on the obj vertex)

[vectoreffect]

create a polygon sphere with 400 vertex, and then using particle tool to create 400 particles without space. Finally, you can add the following script into the particle position area (choose creation expression).

float $verticeX, $verticeY, $verticeZ;

$sel = `pointPosition -w pSphere1.vtx[particleShape1.particleId]`;

$verticeX = $sel[0];
$verticeY = $sel[1];
$verticeZ = $sel[2];

particleShape1.position = <<$verticeX, $verticeY, $verticeZ>>;

[hehehaha]

Why don't you using Goal or Softbody?
It's more simple.

my mel script is difference from goal and softbody. Goal can't attach on the object when the object is moving. The particles on the softbody object can't move away from the object.

My mel script is used to attach particles on the object surface, then you can use any force to move the particles away from the object.

"Goal can't attach on the object when the object is moving." ??:roll:
When you connect the particles to the object by using Goal, please untick the use transform as goal. And also test the conserve value of the particles.
