Group-group collision without physics

[Ynozzar]

Hi,

 

First of all, I'd like to apologize beforehand if this topic was already asked. I searched for it, but found none.

 

So, I'd like to know if there is any way to check for collisions between groups, but without actually using physics. Maybe you'll ask, why would you do that? Well, as physics collision takes quite a bit of memory, I'm trying to find the best possible way to check for collisions, while maintaining the best performance I can.

 

 

Thanks a lot beforehand!
