3.6.3 Snake Movements Whenever the Player makes a valid movement, the Snake will also move for one grid on the map. However, the Snake's movement is randomized. You have to use the random number generator function for the Snake to decide 1 out of 8 possible directions. If the Snake is at the edge of the map OR near the Walls, then some movements will be restricted. (Please be careful here. Moving the Snake outside the map might crash your program due to unauthorized out of bound memory access) * * * **** Figure 3: The Snake can move to 1 out of 8 directions. * *** Figure 4: If the Snake is at the edge/border of the map OR near the Walls, then the choice of movements will be reduced. Please ensure that the Snake does not move out of bound of the map. UCP Assignment Page 7 of 14 Semester 2, 2024 However, if the Player moves to a grid on which it is exactly ONE grid away from the Snake, then the Snake will just move to eat the Player without any random movement. P- (a) Player moves closer to the Snake. (b) Snake moves to eat the Player. Figure 5: The Snake will move in the direction of the Player only if the Player is one grid away from the Snake.

CAN YOU HELP ME WITH MAKING THE SNAKE MOVEMENT LOGIC MORE REFINED INSTEAD USING RANDOM DIRECTIONS I WANT IT TO USE A LOGIC TO CHASE THE PLAYER AND ALSO CAN YOU MAKE IT LOOK LIKE THE OUTPUT OF THIS PICTURE?
