I am wondering if it is possible to detect collision between more than 2 objects at a time? I want to be able to create a match three kind of game like the candy crush type.
You can do a collision check and then use the action or condition to count the number of colliding objects:
Conditions: RedCandy collides with RedCandy
Number of RedCandy is >= 3
Actions: Delete object RedCandy
The problem is that if two RedCandy are colliding in some place and other two RedCandy are colliding in another location, GD will pick all of them and the object count will be 4.
