Help with collision Resolution -SOLVED

Questions

I am having some trouble with resolving collisions. I have a collisions table that collisions are pushed to whenever the script receive’s a contact_point_response message. When the object moves, it travels at a velocity that begins at its initial velocity and is lerped to the velocityGoal, to give a smoother transition. Upon colliding with something, I want it to bounce off at an angle corresponding to the angle that it entered at. The script I have below works for some cases, but other times it passes straight through the collision. Any help? Thanks!

for i = 1, #collisions do
		local collisionNorm = collisions[i]["normal"]
		local collisionDist = collisions[i]["distance"]
		if collisionDist > 0 then
				if (velocity.x > 0 and collisionNorm.x < 0) or (velocity.x < 0 and collisionNorm.x > 0) then
					velocity.x = velocity.x * -1
					velocityGoal.x = velocityGoal.x * -1
				end
				if (velocity.y > 0 and collisionNorm.y < 0) or (velocity.y < 0 and collisionNorm.y > 0) then
					velocity.y = velocity.y * -1
					velocityGoal.y = velocityGoal.y * -1
				end
				local newpos = selfPos + collisionNorm * collisionDist
				go.set_position(newpos)
		end
end
--clears the collision array
collisions = {}

Got it figured out, sorry for the dud post :sweat: The problem was that the initial velocity, which was used as the starting point for the LERP up to the velocityGoal needed to be inverted as well, or the lerp would return unexpected velocities.
