Method Summary

Modifier and TypeMethod and Description
public Array<AssetDescriptor<T>>
getDependencies(String fileName, FileHandle file, PolygonRegionLoader.PolygonRegionParameters params)

Implements abstract com.badlogic.gdx.assets.loaders.AssetLoader.getDependencies.

If the PSH file contains a line starting with params.texturePrefix, an AssetDescriptor for the file referenced on that line will be added to the returned Array.

public PolygonRegion
load(AssetManager manager, String fileName, FileHandle file, PolygonRegionLoader.PolygonRegionParameters parameter)

Implements abstract com.badlogic.gdx.assets.loaders.SynchronousAssetLoader.load.

public PolygonRegion
load(TextureRegion textureRegion, FileHandle
file handle to the shape definition file
file)

Loads a PolygonRegion from a PSH (Polygon SHape) file.

public Array<AssetDescriptor<T>> getDependencies(String fileName, FileHandle file, PolygonRegionLoader.PolygonRegionParameters params)

Implements abstract com.badlogic.gdx.assets.loaders.AssetLoader.getDependencies.

If the PSH file contains a line starting with params.texturePrefix, an AssetDescriptor for the file referenced on that line will be added to the returned Array. Otherwise a sibling of the given file with the same name and the first found extension in params.textureExtensions will be used. If no suitable file is found, the returned Array will be empty.

public PolygonRegion load(TextureRegion textureRegion, FileHandle file)

Loads a PolygonRegion from a PSH (Polygon SHape) file. The PSH file format defines the polygon vertices before triangulation:

s 200.0, 100.0, ...

Lines not prefixed with "s" are ignored. PSH files can be created with external tools, eg:

Parameters
file:FileHandle

file handle to the shape definition file
