Okay, you see in the second video the moving circle on the floor? that's "center" or "origin" in the animation. Wherever that center goes is where the game thinks your character is at any given moment. This is also typically called "root".

Select the animation file.
In the inspector  open the Animation tab.

There should be a 3 drop down menus.

I forget the exact wording
But you want these drop downs to all be set to Original. And to check the box that says bake into pose under each drop down

Amazing bro . it is working perfectly now . you are awesome. thank you very much

@ xFTLxKingPhoenix one question more . hope u can help me in this, or i can hire you .both way am happy

I want to ask on what class should I open to make modification on the movement of the character. I already tried to check the PhysicsScript, MoveInfo, MoveSetScript, and ControlsScript and did some modifications but I cannot seems to find the actual code for movement? I found the "Move" method in PhysicsScript and tried to edit but no changes. What I'm aiming is to edit the movement of the characters to move around from x,y,z not just only in x and y. I want the character to move like in wrestling match, boxing, or UFC.

Looking forward to your answer. Thank you!
