Detailed Description

TextureInfo holds a Texture2D object and caches associated tile UV data.

The source region for tiling is not necesseraly the entire texture, it can be any oriented box in UV domain. TextureInfo takes ownership of the Texture2D object passed to it, and disposes of it in its Dispose function.

Constructor & Destructor Documentation

TextureInfo

(

Texture2D

texture

)

TextureInfo constructor.

Note: TextureInfo takes ownership of the Texture2D passed to this constructor, and disposes of it in Dispose.

TextureInfo	(	Texture2D	texture,
		Vector2i	num_tiles
	)

TextureInfo constructor.

Note: TextureInfo takes ownership of the Texture2D passed to this constructor, and disposes of it in Dispose.

Parameters:

texture	The source texture.
num_tiles	The number of tile subdivisions on x and y.

TextureInfo	(	Texture2D	texture,
		Vector2i	num_tiles,
		TRS	source_area
	)

TextureInfo constructor.

Note: TextureInfo takes ownership of the Texture2D passed to this constructor, and disposes of it in Dispose.

Parameters:

texture	The source texture.
num_tiles	The number of tile subdivisions on x and y.
source_area	The source rectangle, in UV domain, on which we are going to build the tiles (bottom left is 0,0).

Member Function Documentation

void Initialize	(	Texture2D	texture,
		Vector2i	num_tiles,
		TRS	source_area
	)

The actual init function called by TextureInfo constructors.

Parameters:

texture	The source texture.
num_tiles	The number of tiles/cells, horitonally and vertically.
source_area	The source rectangle, in UV domain, on which we are going to build the tiles (bottom left is 0,0).

Property Documentation

Vector2 TileSizeInPixelsf [get]

Return tile size in pixels as a Vector2.

All tiles have the same size.
