Original Post
I got a tile mapping engine (well, borrowed) it uses Andre LaMothe's method (as per his book) with his BOB engine (I need to get around to making my own someday - although my engine does have modifications in it)
Im able to go just about anywhere Out of Bounds (of the map) without the thing crashing (yay for me!)
However, if I go OB on the X axis the tile's still get drawn (IE: whatever th last row is, that will be filled in as i go along) No problem on the Y axis
Any ideas to get this to stop?
("world" is a 20x20 char.)
inline void TNW_Engine(void)
{
int start_x, start_y;
int end_x, end_y;
int offset_x, offset_y;
int texture_x, texture_y;
start_x = world_x / 64;
start_y = world_y / 64;
end_x = start_x + 9;
end_y = start_y + 6;
offset_x = -(world_x % 64);
offset_y = -(world_y % 64);
if (offset_x)
end_x++;
if (offset_y)
end_y++;
texture_x = offset_x;
texture_y = offset_y;
for (int y = start_y; y <= end_y; y++)
{
for (int x = start_x; x <= end_x; x++)
{
textures.x = texture_x;
textures.y = texture_y;
textures.curr_frame = world[y][x];
if (textures.curr_frame != NULL)
Draw_BOB(&textures,lpddsback);
texture_x += TILE_SIZE;
}
texture_x = offset_x;
texture_y += TILE_SIZE;
}
}
