Animate character doesn't work

I decided to try and animate, but regardless it doesn’t do anything, and the character always floats. Dynamic or static.

It looks like you’re keyframing at a different z axis then your object’s initial z axis. Make sure the pose origin is the same as the object origin, e.g. if z axis in object mode is at 0.0, make sure in pose mode you keyframe the z axis at 0.0 as well.

your dude is set to static

The existing Ai goes through any new objects added, as well the player can’t get past them if they are there once not active in the scene. Static won’t work for the AI model object as that physics option creates a barrier, so what exactly is the solution for that?

The new AI floats around, it is a dynamic. Just locking the Z help with that?
