Master R0J0hound, I'm using the Canvas plugin (which is definitely the solution for this case), but I still cannot solve this problem.
I'm trying to draw a line with the canvas whenthe player touch the screen, so the beginning of the line should amend it in order to involve an object. This "circle" must be filled by the canvas, creating a temporary object to be detected for collisions.
I tried with Path, Move Pen, Draw Path and other with the Touch behavior, but I had no success.
Sorry to bother you, but I'm just asking for help because I am not familiar with this great plugin.
In advance thank you for your attention and collaboration.
