Maybe I'm just having a brain fart or some such, and as best I can figure this bit of code should work.

Background:
This code takes world chunks arranged in a 10x10 grid (0-9). Each chunk is a 96x96 tiled map. The display area of the map is 13x13 This code should read parts from other world chunks if the player is on the edge of a particular world chunk. However, when the player walks into another world chunk it seems to forget to read the chunk they just came from. Any help would be appreciated.

Could you show a screen shot of the problem?

Correct me if I'm wrong, you want the world chunks that the player is not on to be darker but when you cross to a different chunk nothing happens to the previous chunk?

A screenshot by itself isn't very revealing unless its in motion.

Let me clarify a bit:

Lets say player is on World Chunk 3X 2Y and moves north onto 3X 1Y (After stepping from Map Coordinate Y 0. It seems once the player crosses onto the new world chunk and onto Y 96 the above code seems to forget to update anything south of him (in the old Chunk)...until the old chunk is completely out of view (out of the 13x13 display area). Once the player heads back south though, the chunk that he came from before (at 3X 2Y) seems to read again fine.

Nothing to do with making the tiles around him darker.

Took your post long enough to show up.

I get a better understanding of your problem now. I took a look at your code again and might have found something.

Is this suppose to be "OR iModChunkY > 9" or "OR iModChunkY > 96"?

I think this 'IF' line is the culprit...



I think the last iModChunk variable is missing the 'X' (should read "iModChunkX" just before the final "> 96")

And like Ashingda 27 said.., is the second iModChunkY supposed to be "> 96" (since you mention that "the player crosses onto the new world chunk and onto Y 96")

Anyways I think this line in the code is where the problem is, it looks wonky.

Cheers!
