How would I work with Gui Collision?

Here's a function to check for GUI collision. You call it like this:

if isColliding(enemy, player) then --blah end

function isColliding(body1, body2)
	local b1x = body1.Position.X.Scale + body1.Position.X.Offset
	local b1y = body1.Position.Y.Scale + body1.Position.Y.Offset
	local b1sx = body1.Size.X.Scale + body1.Size.X.Offset
	local b1sy = body1.Size.Y.Scale + body1.Size.Y.Offset

	local b2x = body2.Position.X.Scale + body2.Position.X.Offset
	local b2y = body2.Position.Y.Scale + body2.Position.Y.Offset
	local b2sx = body2.Size.X.Scale + body2.Size.X.Offset
	local b2sy = body2.Size.Y.Scale + body2.Size.Y.Offset
	
	return (
		b1x + b1sx > b2x and
		b1x < b2x + b2sx and
		b1y + b1sy > b2y and
		b1y < b2y + b2sy
	)
end

GUI collision is actually really simple once you wrap your head around it. It's just simple comparisons using > and <. If you want an in-depth explanation, just ask.
