help with walk cycle

I’ve tried some tutorials of making an in-game walk cycle but every time I tried it just don’t work. I’ve made an action for the animation of 20 frames where my model is attached to the armature (parent --> armature). The logic bricks are : ALWAYS ___________> AND _____________> ACTION : LOOP STOP. When I press the P key to see the GE result, my model don’t move. I guess I’ve done something wrong but I don’t know what…

Does your armature have any constraints? If so - not every constraint is supported by game engine.

no my armature is really really basic

If you could post the blend file it would be easier. Its hard to tell right now what is wrong.

very very basic ^^
