Hardon Collider Help

[Ethan-Taylor]

In your custom border collision code, you are dividing the circle radius by 2 as if it were the diameter. There will be no shape intersection if you use 30 (half the width of your circle) instead of 30/2.

Also you should have player:draw('line') instead of player:draw('line',50) on main.lua:103

Ahh I see, so the value of 30 is the radius, not the diameter. Thank you.

I did, the wall collision worked fine?

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

[FruityLark]

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.

Code: Select all

function onCollide(dt, shape_a, shape_b, dx, dy)
if shape_a.type == "player" then
	--movement.yvel = 0
	--movement.xvel = 0
	shape_a:move(dx, dy)
end
end

end
end

How do I calculate dx and dy?
The player just seems to go right past the sqaure

[FruityLark]

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.

Code: Select all

player = collider:addCircle(movement.x, movement.y, 30)
player.type = "player"

Hmm, still the problem ...

Code: Select all

function onCollide(dt, a, b, dx, dy)
	if a.type == "player" then
	--	movement.yvel = 0
	--	movement.xvel = 0
		a:move(dx,dy)
	end
end

Everything else is working fine.

I can't see what you're missing without the code. Try the attached version.

just set the velocity to 0 now?
