Question

how do I get my object (while programing) from point B to point A

Answer 1

Answer:

In your main loop, before you call Draw you change the position of the zombie. Make its position (on X or Y axis) one step closer to the player.

This can easily be done since you know the current position of the player. If zombie-X is higher than player-X, then decrease zombie-X. Or if opposite then increase zombie-X. Same with the Y position.

To not make the zombie just walk up-down (or left-right) you adjust the X position of the zombie every second time in the main loop, and the Y position every second time. Or you could select X or Y randomly.

In short, your "point B" is always the players current position.
