Tow truck is not towed #2

Closed Adrian400811 closed 4 months ago

Adrian400811 commented 4 months ago

Sometimes a tow truck is not being towed after crashing. Probably getting null as "tower"

Adrian400811 commented 4 months ago

Separate it from the drive method. make it "move to towtruck.getX() - (some distance)" instead. Tow truck disappear will cause null pointer. Make it self-destruct if tow truck = null.
