-
Creates a new Texture using the given config values.
Generated textures consist of a Canvas element to which the texture data is drawn.
Generates a texture based on the given Create configuration object.
The texture is drawn using a fixed-size indexed palette of 16 colors, where the hex value in the data cells map to a single color. For example, if the texture config looked like this:
var star = [ '.....828.....', '....72227....', '....82228....', '...7222227...', '2222222222222', '8222222222228', '.72222222227.', '..787777787..', '..877777778..', '.78778887787.', '.27887.78872.', '.787.....787.' ]; this.textures.generate('star', { data: star, pixelWidth: 4 });Then it would generate a texture that is 52 x 48 pixels in size, because each cell of the data array represents 1 pixel multiplied by the
pixelWidthvalue. The cell values, such as8, maps to color number 8 in the palette. If a cell contains a period character.then it is transparent.The default palette is Arne16, but you can specify your own using the
paletteproperty.Parameters:
Name Type Description keystring The unique string-based key of the Texture.
configPhaser.Types.Create.GenerateTextureConfig The configuration object needed to generate the texture.
