This is an old compound I made for a production. It is just another goal compound, this one gets the point index of an object as goal :
particle 1 goes to point index 1
particle 2 goes to point index 2
particle 3 goes to ...
It suddenly get some interest since I red this topic :
Now it can reorder the goal point Index according to the distance of an object.
I defenetly don't want to take any credit for this. All the hard work made by "Stevegh" and Anto Matkovic.
