How does SWEPT AABB collision work in 3D space with objects of different sizes?

In the case of small round objects (bullets, hand grenades, etc) here's what I did:

  • Rather than a true AABB, i used a structure like this
  • XMFLOAT3 vCenter
  • float XScalar, float YScalar, float ZScalar
  • This gives you the center of AABB, and then three vectors that can be stretched on each axis (X,Y,Z). …

    Do you maybe have a suggestion on how I can check if the simplex GJK returns is correct?

    Store your minkowski vertices as point A and vector (A-B), rather than only A-B like you do now. Then, you can know the points on shape A and B in world space that make up the simplex on each obje…

    I need it to get my game working for my school project.

    Thread locked. We have a “no homework” policy here. We may need to institute a “no Pascal” rule too. :p

    Arkanoid and PyGame Collision Detection
    Background

    I chose to write an Arkanoid-like clone (see the original below), assuming this would be a relatively simple place to start with PyGame.

    Arkanoid. Fresh outta the 80s.

    So I coded away and felt joy and satisfaction as I quickly implemented a sprite sheet loader, platform movement, block an…
