Add a private variable to the particle objects, and assign a different value to each.
+>if partcles.value("num") = 1
-> particle's set position to object.imagepointx ,object.imagpointy("a")
+>if partcles.value("num") = 2
-> particle's set position to object.imagepointx ,object.imagpointy("b")
But there's only 1 particle object. If so, how could I duplicate the first object?
