Plugin Help [1.8] Custom Entity Control [Help needed]

Hello,

For my test server I am trying to make a Plugin, like whenever you type /test a Blaze will spawn and you will be set as a passenger of the Blaze.

What I have working so far:
- Adding the CustomEntity
- Spawning the CustomEntity
- And set the player as passenger

I found a peace of code on the intenet to control a Custom Entity by using the WASD Keys on your keyboard.
But like the Speed of the Entity is too high! And like the controls are not working properly like when I try to go forward (By pressing W) it will go backwards and same for the side movements A is Right and D is Left. And it isn't going up aswell.

Custom Entity (Blaze):

Code:

public class RideAbleBlaze extends EntityBat {
   
    Player rider = null;
   
    public RideAbleBlaze(net.minecraft.server.v1_8_R3.World world, Player player) {
        super(world);
        this.rider = player;
        this.setSize(10, 10);
    }

   
    @SuppressWarnings("unused")
   
   
    @Override
    public void g(float sideMot, float forMot)
    {
      if ((this.passenger == null) || (!(this.passenger instanceof EntityHuman)))
      {
        super.g(sideMot, forMot);
        this.S = 0.5F;
        return;
      }
      EntityHuman human = (EntityHuman)this.passenger;
      this.lastYaw = (this.yaw = this.passenger.yaw);
      this.pitch = (this.passenger.pitch * 0.5F);
      this.setYawPitch(this.yaw, this.pitch);
      this.aK = (this.aM = this.yaw);
      this.S = 1.0F;
   
      sideMot = ((EntityLiving)this.passenger).aZ - 0.00001F; //backwards
      forMot = ((EntityLiving)this.passenger).ba;
      if (forMot <= 0.0F) {
          forMot *= 0.25F;    // Make backwards slower
      }
      sideMot *= 0.35F;    // Also make sideways slower
   
//      float speed = 0.35F;    // 0.2 is the default entity speed. I made it slightly faster so that riding is better than walking
//      this.f(speed);    // Apply the speed
      super.e(sideMot, forMot);    // Apply the motion to the entity
     

      super.g(sideMot, forMot);
      try
      {
        Field jump = null;
        jump = EntityLiving.class.getDeclaredField("aY");
        jump.setAccessible(true);
        if ((jump != null) && (this.onGround)) {
          if (jump.getBoolean(this.passenger))
          {
            Logger log = Logger.getLogger("minecraft");
            log.info("Nu");
            double jumpHeight = 0.5D;
            this.motY = motY + jumpHeight;
          }
        }
      }
      catch (Exception e)
      {
        e.printStackTrace();
      }
    }
}

    }

Hopefully someone could help me understand the code and how to solve the problem.
If you need any more information just ask me!
