I am having trouble loading in a map i made with mappy32 and displaying it using opengl. I appear to get rubbish instead of my map i created. here is my map loading function and rendering function. If someone could tell me where i am going wrong it would be greatly appreciated! map loading
	int value1=0;
	ifstream load;
	load.open("maze1.map", ios::binary);
	if (load.fail())
		return false;
	// map size info above...

		for (int i = 0; i <28; i++) 
			for (int j = 0; j <25; j++) 
				load.read((char*)&value1, 1);
				mapdata[i][j] = value1;
		// map data is now in mapdata[x][y]

	for (int j=0;j<28;j++)
		for (int k=24;k>-1;k--)
			glBindTexture(GL_TEXTURE_2D, texture[(mapdata[j][k])].texID);
				glVertex3f(j-0.5f, -k+0.5f, 0.0f);
				glVertex3f(j+0.5f, -k+0.5f, 0.0f);
				glVertex3f(j+0.5f, -k-0.5f, 0.0f);
				glVertex3f(j-0.5f, -k-0.5f, 0.0f);
mapdata[28][25] is an array i create. I am sticking with the one size map for the time being. the map file is just saved with mappy32 and each byte represents a tile. At this stage there are only 2 tiles. So its either 0 or 1 that gets passed into mapdata[][]. If u need more code just ask! Werdy666
