 |  Subject: SPARK Collision with 2D Object?  Mon 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)) | |
