2D Map Is Not Fully Being Drawn

[GreenTiger]

Okay a friend of mine is working on a 2-D Strategy Game (Like C&C Red Alert) He is trying to create a map that you'll be able to scroll across when you move the mouse to the edge. Currently, his map doesn't even finish getting made. He has map files slightly similar to my isometric ones, reads them and draws a sprite for each tile on the map so that he can scroll across it.

But right now, it only draws a section of the map, and we don't know why. It's still processing for the full time (we PUTed the values to the screen and when it reaches a certain number, the values continue to increase, but it simply stops drawing sprites.

Do you have any idea what could be causing this problem?

(He is willing to give me the code to post here if you need to take a gander)

the code for drawing loop would help

otherwise it should be two forloops

code:

for x:screenLocationX .. screenWidth + screenLocationX     for y:screenLocationY .. screenHeight + screenLocationY          Draw(x,y)     end for end for

should be getting code from him soonish
