I’m trying to make a space invaders game using Processing Python but for some reason when a barrier is destroyed and I try to repopulate it after the player tries to play again, the entire code just freezes I think. The barriers are stored in a global list called barrierlist and I use global barrierlist to try to tell that I’m trying to modify the global variable.
Below is the actual code written, please excuse the numerous print statements as they were mostly for debugging purposes. I believe that all the global variables are correctly defined but for some reason, I still cannot repopulate the barrierlist in the “elif (gameOver == True and victory == False):” and “elif (gameOver == True and victory == True):” sections.
