"homing" missiles?

BlitzPlus Forums/BlitzPlus Programming/"homing" missiles?

I've been trying to do this for a while now....Basically, what I need is an algorythm that points an enemy or enemy's missile towards the player each frame. I thought it would be something to do with sin/tan and the player's x and y position, but I can't get my head around it...:S

Can anyone help me with this?
