TestWalkingChar

Im trying to get shooting working in my game and I’ve been poking around. TestWalkingChar has been mentioned a lot in terms of getting a direction of a projectile relative to the players direction which is the problem im trying to solve. However this is a lot of errors in the file, fore example:

package:com.jme3.terrain.jbullet does not exist.
or
package com.jme3.bullet.nodes does not exist.

Is there any newer files where when you shoot something it goes in the direction of your character?
