Well I'm currently away from home, and will be for a week. As for where I am, well I'm in a city called Leicester and living in my brothers house.

Because of this I doubt I'll get any programming done because:
1. I didn't bring my laptop
2. I'm on a mac

However there is a chance that I will do something. If I can get xCode installed then maybe I could get my engine/game working on a mac. Of course this will take a lot of time so then again maybe not.

Anyway here is some code which I converted from blitzMax to c++

void LightMap(int x, int y, int radius){	float a1, a2;	int tx, ty, k;	for (a1 = 0.0f; a1 < 90.0f; a1 += 0.5f)	{		a2 = a1 * 4.0f;		for (k = 0; k < radius; k ++)		{			tx = x + (cos(a2) * k) + (tileset.width / 2.0f); // Needs to be centred so add  1/2  tile width/height			ty = y - (sin(a2) * k) + (tileset.height / 2.0f);			tx = tx / tileset.width;		        ty = ty / tileset.height;			if (tx > 0 && tx < width && ty > 0 && ty < height)			{			tile[tx][ty].explored = true;					if (tile[tx][ty].vBlock == true)				{					break;			        }				else				{					tile[tx][ty].fogged = false;			        }		        }		}	}}

-- Not sure if it works, this is just a rough interpretation of the code. I have a working version at home.
