How does one make mesh animations?

How does one make mesh animations work in the blender game engine?

It’s quite easy:
You animate your mesh in a normal way, then select the desired mesh, and add a Ipo or Action Actuator with the desired frames values and motion
To fire/control the animation you can use whatever: A keyboard sensor, or a collision, or link it to another object
Is this clear?

vertex key [absolute or relative] do not work in the game engine

armature animations do, you play them using an action actuator on the armature object

thanx for the imput, z3r0 d…
I thought they weren’t supported.
