after i try the first example of construt 2,
i decide to use it to make a puzzle bobble game,
when the bobble on collison with another bobble, i set the bullet speed to 0.
but sometimes the two bobbles will overlapped a little.
i think it's the reason that the trigger is a little late.
how Can i solve this problem?
i added the behaviour "solid" as Ubivis says in
and it not works.
thank you, all!
