	Since TTD is a palette-based game, you have to be careful that the graphics program you use can deal with that properly. Also, TTD uses some palette entries for palette cycling to do some colour-animation, don't use these as regular colours. These entries are often called "action colours".

	TTD internally uses a 3D engine, which ~~then~~ uses an isometric projection to display graphics on a 2D screen. The 3D engine uses so-called "bounding boxes" for each sprite, which are ~~then~~ sorted by the sprite sorter to get drawn in (what it thinks is) the right order.		TTD internally uses a pseudo-3D or [http://en.wikipedia.org/wiki/2.5D 2.5D engine], which uses an [http://en.wikipedia.org/wiki/Isometric_graphics_in_video_games isometric projection] to display graphics on a 2D screen. The graphics engine uses so-called "bounding boxes" for each sprite, which are sorted by the sprite sorter to get drawn in (what it thinks is) the right order.

	To get a certain sprite drawn at the right place, it needs to have a proper bounding box (which is provided by the game for the most part), and the correct 2D offsets, here called "xofs" and "yofs" (see [[RealSprites]] for more information). The following picture by Oskar Eisemuth should help in figuring out how the 3D and 2D coordinates relate to each other:		To get a certain sprite drawn at the right place, it needs to have a proper bounding box (which is provided by the game for the most part), and the correct 2D offsets, here called "xofs" and "yofs" (see [[RealSprites]] for more information).
