----------------------------------- Vertico Thu Apr 14, 2005 5:57 pm Help with whatdotcolor ----------------------------------- trying to make a pacman game, and i am stuck. im trying to get the oval 2 stop when it reaches the blue walls but when i try and do if whatdotcolor (x , y ) = blue then it doesnt understand it and lets the oval go right throught the blue wall. but if i put if whatdotcolor ( x, y ) not= black then it works and stops when it hits the blue wall. this isnt good cuz i want 2 put in coins and warps but if it stops when its not black then that stuff isnt going to work. can someone show me how 2 use this, or maby an easyer and faster way. thz. :D ----------------------------------- Martin Thu Apr 14, 2005 6:14 pm ----------------------------------- Don't use whatdotcolour, and instead use a 2d array to store your map. ----------------------------------- Vertico Thu Apr 14, 2005 6:21 pm ----------------------------------- i dont understand what u mean by 2d array ----------------------------------- Martin Thu Apr 14, 2005 6:34 pm ----------------------------------- Search the forums for a 2d array tutorial. ----------------------------------- Andy Thu Apr 14, 2005 6:50 pm ----------------------------------- martin u sux... go whatdotcolour!! see you have to check the next step, you need to check if (x+1,y) or (x-1,y) or (x,y+1) or (x,y-1) is blue ----------------------------------- Vertico Thu Apr 14, 2005 7:00 pm ----------------------------------- andy can u give me the exact code for that. PLZ :shifty: ----------------------------------- Andy Thu Apr 14, 2005 7:13 pm ----------------------------------- sure... why dont i just do the whole freaking project for you while im at it? use ur brain, thats why you have one, if you cant, then too bad, drop compsci ----------------------------------- Token Thu Apr 14, 2005 7:52 pm ----------------------------------- heres what you have to do, you have to check if 1 pixel in front of your oval is blue, not the center of your oval, because it will obviously be blue.. so do somthing like this if whatdotcolor (x , y+radius ) = blue then %%if your heading up ----------------------------------- jamonathin Fri Apr 15, 2005 7:44 am ----------------------------------- I think you just took away andy's point. ----------------------------------- Martin Fri Apr 15, 2005 8:06 am ----------------------------------- Make sure you don't draw the pacman until AFTER you use the whatdotcolour. ----------------------------------- Vertico Fri Apr 15, 2005 2:29 pm ----------------------------------- i found out what i was doing wrong. the picture was "brightblue" instead of just blue. even thou they look almost the same. ----------------------------------- Token Fri Apr 15, 2005 4:25 pm ----------------------------------- no i didnt give him the exact code i just gave him an idea of what he had to do, if i were to give him all the code like the if statement for all 8 directions then that would be taking away andys point
