SPARK Collision with 2D Object? Empty
PostSubject: SPARK Collision with 2D Object?   SPARK Collision with 2D Object? Icon_minitimeMon Oct 17, 2011 10:46 am

Hello,

My Problem:
I don't understand how to check a Collision between two SPARK Systems and how to check a Collision
between an System and an SFML Sprite...

I tried many many things and look in the examples, but I dont unterstand it, really...

My last try was this:
Code:
if(    System_1->GetPosition().x +  System_1->getAABBMax().x    >  System_2->GetPosition().x + System_2->getAABBMin().x
    && System_1->GetPosition().x + System_1->getAABBMax().x      <  System_2->GetPosition().x + System_2->getAABBMax().x
    && System_1->GetPosition().y + System_1->getAABBMax().y      >  System_2->GetPosition().y + System_2->getAABBMin().y
    && System_1->GetPosition().y + System_1->getAABBMax().y      <  System_2->GetPosition().y + System_2->getAABBMax().y)
{
//Collision
}
But I think this is very wrong...
Thanks for all help!

If your spawning particles in system space and use only translation (no rotation) of systems, your code is ok (there s a little error though... I let you find it)
What you need to do is priorly enabling aabb computing for every systems and underlying groups (using enableAABBComputing(true))
