The program work like this.If I press 'C' button in keypad, a fire image should blow in the screen.But the problem is it is not working as expected.I am not able to figure out what is the issue.

problem wih lights

Post by gamerfan »

somehow I was able to correct it.the image loaded.But now the problem is we can see the square box in which the image has included.I have added transparent to it.Still it is coming a square box.I do not know how to remove that.Please shed some light if any knows it.

Thanks in advance

Please post a minimal compilable snippet which reproduces the problem.
Thousands of 'System.out.println' really make browsing the code harder.

And using code-tags would help to improve readability too.
