Slowing down

here is the code that moves the objects (in main loop). so the "moving it by 0.1 units insted of 1 units at a time" seems simplest..how would i incorporate this here?

For i=0 To 100
MoveEntity spheres(i), Rnd(-0.5,0.5), 0, Rnd(-1.2,1.2)
 
Next

i really have no idea and really appreciate your help

thanks
