How do I make the ball hit the 2 rectangles whenever the ball hits one of them it just goes through it.

function touched(t)
    if math.abs(t.x-r.x)<200 and math.abs(t.y-r.y)<200 then
        r.x=t.x
        
    end
    if math.abs(t.x-r2.x)<200 and math.abs(t.y-r2.y)<200 then
        r2.x=t.x
        end

@Joey720999 You have to set the two bodies to a certain type of physics body. Look at the reference manual under physics to see how to set it and what types you need

@Goatboy76 ok thanks

@Joey72099 I changed your code a little to get it working. You can change it to your liking. I changed the beginning velocity so it bounces from rectangle to rectangle to show it works.
