Monsters!

It was surprisingly easy to get the monsters in and animated, and facing the correct direction in relation to the player. Basically the player has one of 4 directions (0, 1, 2 and 3) and the monster has 1 of 4 directions (0, 1, 2 and 3) and you subtract the monsters direction from the players direction to give you which sprite to plot. If the result is less than 0 you add 4.

E.g. if player is facing East (1) and enemy facing South (2)

1-2 = -1
-1+4 = 3

Plot monster sprite 3. Repeat!

Looking good! Also, I believe Gazillion's optimization should be more like ((Pd - Md) + 4) % 4.

Sorry I mixed up the two parameters, I meant (Md - Pd) % 4 which will give you the same results as adding +4 to negative numbers and leave the positive ones unchanged.

Looks like the editor doesn't like me pasting from excel, but the math is good (or am I really that tired? :P)[s]
