I have some code where a tank is positioned at the screen and the tank will move to the location you specify by the right mouse click, the tank is a class called Tank. However i've run into a weird problem, when i load the tank outside of the while loop (before the while loop) everything works fine, but if i load the object inside the while loop, the object will only move when you hold your right mouse button in, (it will not move to the specified location unless you hold in your right mouse click all the time).
This is the piece of the with the object loading outside of the while loop.
The problematic code is marked with stars.

This is the code if i place the object loading inside the while loop, the object will only move when i hold the right mouse button in.
