Code	/** * Use the arrow keys to move Hopper through the maze. * * Start at the safe green square on the left. * Finish at the checkered flag on the right. * * Blue areas are impassable water. * * Guards patrol the area along a set route. * If you run into them you will lose a heart and * and must return to the beginning square. * The beginning square and finish square are safe from guards. * The game is over when you lose all hearts. * * Small red guards patrol areas farther from the exit. * Small green guards patrol areas closer to the exit. * Large red guards patrol areas mainly farther from the exit * and will venture closer. * Large green guards patrol areas mainly close to the exit * and will venture farther. * * Guards will appear depending on maze configuration. * * Press H to activate a blue crystal. * Blue crystals show you the exit route. * * Press K to activate a key. * Keys let you pass through an eastern wall * that you are touching. * * Press I to activate a green crystal. * Green crystals make you invisible to green guards * for 5 seconds. * * Press N at any time to go to the next maze. * * Press R at any time to restart the game. / /* * Help Hopper Escape * * Troy Cook / / This program uses a recursive routine to fill in an area with a random branching path. It does not calculate walls, but determines if a path can be made to an adjacent block. It starts with the exit block and completely fills in the area. Any block can be used as the beginning. Help will also solve the maze and draw the exit route on the path. 3/23 Added more guards with different patrol areas and speed. Corrected pathRandom routine. Beginning square is now safe. Invisibility to green guards. Updated Hopper movement. 3/19 Updated maze algorithm to increase difficulty. Start on the left and finish on the right. Water barriers. Health hearts. Game ends when you reach 0. Keys let you pass through an eastern wall. Added useful shortcut. 3/18 Added depth property to determine how far away each block is from the exit. Will use this for future features. / var bug = false; randomSeed(hour()+minute()+second()); var fonts = { serif: createFont("serif",null), sans: createFont("sans serif",null), curs: createFont("cursive",null), };
