Animated enemy

Hi, can someone help me with this problem?
I am making a game in blender and i have a working enemy.
The problem is that the enemy is only a cube who follows me and kills me.
How do i change the cube to an animated monster, who walks, attacks and stuff?.

You will need to first create the monster model and then rig it, create a set of different actions using the action editor, then you will need to use the game engine nodes to call the actions based on what you want the monster to do when you want it to do it. Sorry if that’s a bit confusing.
