Hi.
On collision store the object, then use 'Array Contains' (or 'Array List Contains' if you use Array Maker)
and store the index.
Then you could use a Array Get Next and use the Index as the Start Index.
If you reuse this, you should also set a variable on the 'Reset Flag'
and Before(!) you Array Get Next (in a previous state not in the same state)
Set That variable to true.
