Making AI for fighting sidescroller style, with a hint of 3d illusion

i hav my main characters and then my enemies… wat i want is for my enemies to always be facing my player, and always moving toward the players** X **postion only.

FOR EG

|PLAYER X| <<--------- |ENEMY|

OR

|ENEMY| --------->> |PLAYER X|

hav a look at the link, that enemy i want to move toward mi character wen they move, with good AI similar to the old-school fighter games…
