Problem with my maze
Mar 11^th, 2010, 12:28pm

I am trying to make it so that when you hit the wall of the maze, it will go back to my splash page. Heres the whole code I have so far.
Code:

  PFont font;
  boolean isSplash;
  boolean isDiff;
  int [][] lines = {{102,76,102,0},{76,30,30,30},{102,32,562,32},{65,120,0,120},{447,30,447,120},

first i added a background to the splash, that is needed to refresh the screen and to render the font without aliasing when drawn.
i painted the start and end screen red, but could be anything else just not black as the lines, cause i do a colorcheck at mouse position to reset to splashMode. (if you still want a black line, just use color(1))

Code:

 PFont font;
  boolean isSplash;
  boolean isDiff;
  int [][] lines = {{102,76,102,0},{76,30,30,30},{102,32,562,32},{65,120,0,120},{447,30,447,120},

			  {28,120,28,555},{28,555,485,555},{485,555,485,465},{408,555,408,470},{141,555,141,511},

some might mention that you should use pixels insteadt of get as it is faster. if you want to you can replace it with the equivalent statement to "get(x, y)" using pixels[] is "pixels[y*width+x]".
