Gamer wanna be

Question

k i'll try to describe what i'm looking to do in the most understandable fashion i can manage. in many games there are screens (mostly map screens) where the user moves the mouse to the screen edge and the map scrolls that way. 2 questions. #1. how does one get such a map for instance on a screen and #2. how does one get the mouse to scroll the screen across it. would 'love' to answer these questions if possible. thanks roderus

OK first you'll need a really big map of something. Something that doesn't take up a lot of memory preferably. You will want to load the entire map into memory somewhere. Personally I've used a hidden form that display the ENTIRE map (usually shrunk down a bit) but not neessarily. I then generate a rectangular region (my view screen) and then map appropriate coordinates from my picture to my view screen. You can perform some isomorphic mapping if you want to sort of blow up the image a bit (like a magnifying glass) for display purposes. But essentially you just take a chunk of a picture and display it in a viewscreen. Then in comes your mouse. There are all kinds of mouse functions you can use xPos and yPos properties for the position of the mouse. Based on the position of the mouse and the position of you viewscreen window you can determine the viewscreen threshhold. While the mouse is within a specified distance from the edge you move the view screen over by 2 pixels or 4 pixels at a time until the mouse leaves the region or you cannot scroll any further.
