Method Detail

load

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

Specified by:

load in class SynchronousAssetLoader<PolygonRegion,PolygonRegionLoader.PolygonRegionParameters>

getDependencies

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

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.

Specified by:

getDependencies in class AssetLoader<PolygonRegion,PolygonRegionLoader.PolygonRegionParameters>

Parameters:

fileName - name of the asset to load

file - the resolved file to load

params - parameters for loading the asset

Returns:

other assets that the asset depends on and need to be loaded first or null if there are no dependencies.

load

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:
https://code.google.com/p/libgdx-polygoneditor/
http://www.codeandweb.com/physicseditor/

Parameters:

file - file handle to the shape definition file
