First thing that I did was to create a small circle which will represent the hero in the labirynth. The size is 28x28,
I’ve converted it into an MC (instance name “man” on stage) and within the MC, I’ve created another MC (instance name
“mask” withing the man MC) with the same center, but smaller radius, to be used as the mask for detecting collisions
later on. This allows for greater precision when going through the labirynth around the walls.
