Changes!
- I finished writing up Part 0 and Part 1 of the tutorial. It involves no rolling circles though.
- There are now point-in-shape and ray-intersection tests.
- Tweaks for huge (or mediocre) performance gains
- Point Shapes
- Part 2 of the tutorial
- Part 3 of the tutorial
- Something else? (Any feature you wish for?)

Note: for love compiled with luajit2, the pure lua implementation actually will be faster than using C++ because it is expensive to cross lua/C++ boundary.Robin wrote:It would probably make the most sense to make it Lua-only, because more lovers are familiar with Lua than with C++ and more importantly, if we do use C++ and want to gain any traction, it would have to be included in the LÖVE core, and I don't know how the devs feel about that. If they do want to include it, the heavy stuff and inner loops could probably be done in C++.kikito wrote:Maybe it's a little early to ask this, but - will it be Lua & C++, or Lua-only?

Welcome to the future:
HardonCollider now has point shapes (useful for (slow) bullets and stuff)
I've also fixed this bug and another bug with collisions between circles.

That *is* crazy! (Everyone who doesn't know what I'm talking about: let the ball roll down and wait. Perpetual motion FTW!)vrld wrote:I can offer you one rolling (and bouncing) circle:

I humbly want to request a feature for Hardon Collider.
There is a shape:move() and a shape:moveTo() function. The moveTo sets the position.
There is also a shape:rotate() function. But not a rotate function that sets the rotation. I would really like that.

Done. you can set the rotation with shape:setRotation(). As a by-product, you can get the shape's rotation with shape:rotation().chris wrote:I humbly want to request a feature for Hardon Collider.

Nice 
Another question:
Why is it that if I make a rectangle:
box.x = 5
box.y = 6
box.box = HC.addRectangle(box.x,box.y,50,50)
And I want to move it 3 pixels to the right, I have to write this:
box.box:moveTo(box.x+25+3,box.y+25)
