[Forge 1.8 Eclipse] Issue with keybound-character positioning.

Hey, I'm using forge 1.8 (I'm more familiar in this version, and I'm trying to refresh my knowledge before moving onto newer ones I know little about in comparison) and for some reason everytime I run my keybind post-initialization the game crashes and shuts down... Please help!

    static EntityPlayer player = Minecraft.getMinecraft().thePlayer;
       
    static boolean used;

    static EntityLivingBase entitylivingbase = player;

    public static class KeyInputHandler {
        @SubscribeEvent
        
        public void onKeyInput(InputEvent.KeyInputEvent Event) {
  

            if(activateShikai.isPressed()){
           System.out.println("MODEUP!");
          }
          if(Flashstep.isPressed()){
               System.out.println("FLASHSTEPPED!");
if(used == false) {               
    used = true;
            
    double x = player.getLookVec().xCoord;
                double y = player.getLookVec().yCoord;
                double z = player.getLookVec().zCoord;
                player.setPosition(x, y, z);
}
              }
        }

        }
