for any location where the user is, or wants to go (x,y) you look up if it's a valid location/move on your map (true/false). |

I could be wrong from what you guys mean, but you are looking at doing Multidimental Arrays? Mackie tried to discuss this, I believe. |

You don't have to have a 1x1px resolution, you could use larger boxes for a smaller array map. You also don't have to enter it all manually -- you can load it from a data file, possible the image that you already have. This is just how "whatdotcolour" works, except that it's more stable since you don't share the space with the screen, and you have a better idea of what you are doing. |

so i would have 'if whatdotcolor = white then"... basically? where would the 'whatdotcolor' be located? on the cursor itself? |

Yes, the int whatdotcolour (int, int) function should have as arguments the position of the mouse. If the point is a wall, then the whatdotcolour of that point will return the number of white, and you will know that it is a wall. |

i did something along these lines once. Each picture had a corresponding data file. It would contain lines like this (1,10,40,30) the program would store these coordinates as x and y values and the character would not be able to go within those areas. To make it so that i didn't have to write every area by hand, i wrote a short program that would display the image and allow you to draw red boxes where you do not want the user to go. here's a copy of the map editor that i wrote. In the main program you would have it read the lines and store them as x1, y1, x2, y2 then just have the program check if the user is within that area and move them out if they are. |

Almost. Except that instead of
You will do
Which could be shortened to simply if map(x,y) then X and Y will likely be the position of your mouse or character |
