This engine is created to have a funtion that tells you whether a point is inside a polygon. No variables used To demonstrate you can drag the points and add them. I also put the python code inside in a comment -HOW TO USE THIS ENGINE? Look inside in the engine sprite and backpack the "Is inside" block. The two first inputs are the lists of the coordinates (leave the second empty if they're alternated in only one list) and the third and fourth inputs are for the coords of the point. The output will be the list itself, so you can create an if condition like: if<(inside)=true> than.. -HOW DOES THIS ENGINE WORK? The engine is pretty straight forward, just coding it isn't that easy. Basically you have to count how many sides you intersect in a certain direction from the point. The easiest direction to code this is a horizontal half-line at the right of the point (y is constant and x grows). It counts how many sides the half-line intersects and if the number is odd the point is inside the polygon, otherwise it is outside.
