Cannot cast EntityPlayerMP to EntityClientPlayerMP

[Briggybros]

Hello, I'm trying to make a horse which is controllable by default movements when the character has mounted it. The EntityCientPlayerMP has the movementInput whereas EntityPlayerMP doesn't and that is the player. How I make this work, my code is;

package net.minecraft.src;

     * sprinting.
