This is a simulation of a fire evacuation where the workers run towards the excits when the building is under fire. They have to move around barriers if walls ti reach the exits. The problem is whenever these points take corners they overlap the walls eventhough I have cleartly stated a condition to stop that. I can't figure out why. The condition is if the coordinates of the point in the grid equals 1 the loop is excecuted again. Can someone please help.

There is also an error that comes from time to time when I run the code. It says: IndexError: index 24 is out of bounds for axis 0 with size 24
