GRATS!!!
Thank you, guys!

Sounds like you might benefit from this project: https://github.com/oniietzschan/bump-3dpd It's a fork of bump, prepared to work with 3D. There is also a 2d branch: https://github.com/oniietzschan/bump-3dpd/tree/2d with reduced memory consumption and garbage generation with respect to original bump...

I'm migrating from the Bump and HC collision detection libs. (they are a bottle neck in my project. they take ~40% of CPU) Physics and collisions are almost never a bottleneck in my games, 99% of the time it's love.draw or when I'm blatantly misusing another library. :megagrin: I use some Pie Profi...

Bump uses the closely related Minkowski difference method, both to detect and to resolve collisions.

Yep. I used it. It was nice. Now I'm switching to my own simple functions.

I even recorded 3 long video lessons on how to use Bump. https://youtu.be/caK_BBMum0k

Seems like a roundabout way to do regular AABB collision testing. Instead of testing coordinates against each other directly, it computes differential between coordinates and tests all of them against zero. the pros is it returns the PENETRATION vector (like HC Collider does). It helps u resolving ...

Yo! Has anyone tried to implement this to resolve collisions yet? I found a rather nice & fast algorithm Minkowski Sums . It has been used in RiverCityRansomUnderground game. I translated it into Lua. Now testing Upd: I've hecked up the vectors stuff.... :halloween: function MinkowskiCheckCollision(...

Here is a simple solution of your problem.
At least there is an idea and its implementation in C++

Yo! Cool library.
I was going to use many ifthenS for the same result.

update: I've checked your sources. Well, it is not our case.
I use "push" library and it has all the stretching modes, including the pixel-perfect one.

I had to invent a wheel )))
But it looks pretty the same as yours.

It looks brilliant and produces well self explaining code.
Thank you.
