Help with game applet
Hey,
i have made an applet game which uses multiple classes. when i run it via eclipse with applet viewer it works perfectly, but when i try to open it using a html page, it shows the graphics, but the animation or the mouse listener doesnt work.
What have i done wrong, am i forgetting anything? have i done my HTML wrong? please edit my code and help me
