Only call collision handler once during overlap period?

[Boxtufty]

Simple check solved it, sorry for excellent thread. Remove if you like.

Scenario: I have two entities, when they overlap a handler function executes it's statements.

 

Problem: This collision handler keeps getting called every tick for the duration that the entities are overlapping. I only want it to call once, and then chill out.

 

Mindless rambling: I think this is a matter of logic, like a simple boolean check should solve it.

 

edit: Yep.

// on creation

entity.colliding = false;

 

// in collision handler

if(!entity.colliding){

dostuff;

colliding = true;

}

Typically, you solve this by just simply setting a 'overlapped' flag that gets reset as soon as they're NOT overlapping and set when they overlap.

Would be great to have this overlapped flag built into Ph.
