I am writing a Parabolic Movement Applet. It is going fine, but I have a big problem. The applet simulates the movement by obtaining the values of x and y in every 0.01 m of the movement. However... when it finishes being drawn... it is drawn again.
The same thing happens to the animation of the tower being hit ... it happens twice!
I don't know what to do... :/ I have tried / read everything I can but i can't come up with an answer. Does anyone know?
If you wish to view the applet it is here:
