Web14. mar 2014 · The simple code looks like this: copiedDisplayObject.scaleY = -1; copiedDisplayObject.alpha = 0.4; That is really a specific example of reflection over a line, where the line happens to be the x axis. (ie y = 0x + 0) If you want to reflect over another line, you can use a matrix. WebReflection across a line of given angle Let x,y 𝐱, 𝐲 be perpendicular unit vectors in the plane. Suppose we want to reflect vectors (perpendicularly) over a line that makes an angle θ θ with the positive x 𝐱 axis. More precisely, we are given a direction direction vector u =cosθx+sinθy 𝐮 = cos θ 𝐱 + sin θ 𝐲 for the line of reflection .
