Description

The TextureRegion class specifies a texture and a rectangular region in it. It is used to define independent texture regions within a texture atlas (a large image which contains many smaller sub-images).

Example

<syntaxhighlight lang="lua"> local texture = Texture.new("atlas.png")

-- define 4 equal regions of size 100x100 from "atlas.png" local region1 = TextureRegion.new(texture, 0, 0, 100, 100) local region2 = TextureRegion.new(texture, 100, 0, 100, 100) local region3 = TextureRegion.new(texture, 100, 100, 100, 100) local region4 = TextureRegion.new(texture, 0, 100, 100, 100)

-- add these regions to scene tree local bitmap1 = Bitmap.new(region1) local bitmap2 = Bitmap.new(region2) local bitmap3 = Bitmap.new(region3) local bitmap4 = Bitmap.new(region4)

stage:addChild(bitmap1) stage:addChild(bitmap2) stage:addChild(bitmap3) stage:addChild(bitmap4) </source>

Methods

TextureRegion.new creates a new TextureRegion object
TextureRegion.new
TextureRegion:getRegion returns the coordinates of the region
TextureRegion:getScale returns the scale ratio of the underlying atlas
TextureRegion:setRegion sets the coordinates of the region
