Yea, I didn't word it properly, I meant reversing the bullet's velocity. And yes, as davis mentioned, stationary objects have velocity of 0, where 0 doesn't affect the equation: relative_velocity = object1_velocity - object2_velocity How do we convert the original code into v.xvel and v.yvel? Sorry...

Hello Ethan, It depends if you're going for 'realistic' physics, in which case you can't just reverse the velocity during a collision. For example, imagine a bullet hitting a wall. If the wall is perpendicular to the bullet's path, then you can reverse its velocity: How can the wall have velocity?!

Hey guys, I'm using Hardon Collider for my project. At the moment I'm using it for everything including bullets that the player shoots. function ammo.update(dt) for i,v in ipairs(ammo) do if v.id == nil then v.id = ammo.id ammo.id = ammo.id + 1 end v.bullet.type = v.id v.xvel = v.xvel + 12000 * dt *...

This is not a Hardon Collider Glitch, this is a problem in your collission resolution code. Please attach a .love so we can look at your full code. I've got it now. All you had to do is find the opposite of dx and dy when the obsacle is shape_a. That's because Hardon Collider always finds those val...

I don't think you realize what you are asking. It has taken me years (literally) to get boxes working just right. The amount of math and time it would take to get circles and triangles working as they should is beyond me. Also, the library's interface would have to become more complex to allow for ...

Hey everyone, I'm having another Hardon Collider glitch. Most of the time the collision is flawless, but sometimes it does this: https://love2d.org/imgmirrur/F85et5J.gif and that can get really annoying XD Here's the code: function onCollide(dt, shape_a, shape_b, dx, dy) if shape_a.type == "pla...

just set the velocity to 0 now?

Declare your onCollide function exactly the same as I showed, and you can just use them. HC provides these values (dx, dy) for you to resolve the collision. You also need to add the property 'type' or 'name' or whatever to your player shape, else the if statement in onCollide won't fire. player = c...

Since the square is a collider shape, you need to fix the onCollide function. When you fix this, you will have an interesting situation where the ball jumps to the other side of the square as you continue to force the camera past the square. function onCollide(dt, shape_a, shape_b, dx, dy) if shape...

Don't worry I've fixed it now.
But from this another problem has arised.
The collision with the sqaure is also offset.
