camera tracking empty

I have been trying to figure out a way to make my camera follow the movement of an empty without moving, but it doesn’t work, i tried the trackto constraint, but doesn’t work in GE… so i’m kind of lost, i know there is a way to go get the constraint for the bones with an actuator set on run armature, but is there a way to do it for a camera, or something like that?

if you know a way to do it, it would be appreciated if you could help me out, or send me in the right direction, thank you

always sensor + AND + actuator[edit object][trackTo] ?
