How do I create a laser line type object?

I need to create a laser type line object which will only bounce off of 1 side of a sprite..

Think of a mirror which if the laser hits the 3 sides which aren't reflective it wont reflect but if it hits the reflective side it will proceed to the next object.

I think I know how to make the laser but not too sure about making the object it reflects off.

Any help would be appreciated!

could you make the reflective side a separate sprite from the other 3 sides with on collision send laser to the next object?

Either separate sprites like spacedoubt suggested or if that is impractical for your artwork you could use invisible collision objects, and make only one of them reflect the ray.

ah both great suggestions, never thought about combining two sprites or the invisible object.

Will implement now thanks for the reply's!
