it's an output, first field is the radius, 2nd the outward force, 3rd not to sure (i just put it at 10 or 15, snaily said something to me about upward force)
onactivate>self>radiusimpulse[25][-150][10]
when you click it, it will pull you in once, for it to keep pulling, you'll need to loop it
onactivate>self>radiusimpulse[25][150][10]
and that will push you out
