I've been trying for awhile now to figure this out. All I want to do is make particles emit from one object then goto another one and crawl across it from say point 0-10 to point 9-90. I can get a particle to go from point 0 to 1 but theres a few problems. All the particles that emit from the emitting object seem to jump to where ever the first particle is. Also I want them to go across a grid so the first edge is number 0-10 but the particles will only goto point 0. Any help at all will be much appreciated.
