In the logic buttons, add a sensor. Change the type to keyboard. Set the key to “Up”(do this by clicking on the box and pressing the up button). Add a controller and connect it to the sensor. Now add an actuator and set the type to “Motion”. Play around with the force values. The three values correspond to the 3 axises(axises?). You have to use trial and error to get it right. So try a value, press P, then press up to try it out. If it moves along the wrong axis, try putting the speed in a different box. If it moves on the right axis, but the wrong direction, change the value to a negative number. Do the same thing for the right and left buttons, but instead change the “Torque” values instead of Force.
