Attraction particles without Python

By adding Track to actuator to an object and applying local force to it, it is possible to make that object to follow other object. Then just multiple them and you have particles that are attracted to some object!

Curious and shy

You can make particles behave differently with Ray sensor. Then when particle is close enough target object, other force is applied to it. Just add Ray sensor to the particle and connect it to a Motion actuator. If you define negative Y-axis force in the Motion actuator, then you get sort of "shy" particles.

Here is a example file. Just press P to play and press space key to add particles. You can move target with arrow keys.
