I really don't know any real Scratch application of this...but I made it anyway -- Instructions -- - Click and drag the dot - It tests if the dot is inside the weird alien shape - FPS is there to show the inefficiency of my programming (you can backpack my code it but I don't recommend it) -- Explanation -- There's a point that goes along the x-axis of the draggable dot and counts the number of collisions with the shape until it reaches the dot. If it is even, the dot isn't in the polygon. If the number is odd, then the dot is in the polygon. -- Credits -- - I figured the formula out by myself, but it isn't an original idea - @Zinnea for the tutorial on shape opacity in the editor
