Question

# Modify function given below to add a second
# player-ant to the game. The second player will be controlled by
# another player. The game must be turn-based (alternates between the
# two players) and the first ant to get to the "food" wins the game.
#
#   1: Make the other ant controlled by the computer. The game
#   should still be turn-based but the computer ant will navigate by
#   itself to the goal.
#   2: Create a list of ants. The user can decide how many
#   ants to add to the stage. Some or all of the ants can be controlled
#   by the computer.

      antY=antY+gridSize
      stepsTaken=stepsTaken+1
    
addRectFilled(stage,antX,antY,gridSize,gridSize,black)

if antX==goalX and antY==goalY:
    addText(stage,antX,antY,"Yum!",red)
    foodLeft=foodLeft-1

if foodLeft>):
    dir=requestString("A:Left, S:Down, D:Right, W:Up, X:Exit")
    dir=dir.upper()
  
addText(stage,50,50,"Steps taken: "+str(stepsTaken))
