Class ResolutionFileResolver

java.lang.Object

com.badlogic.gdx.assets.loaders.resolvers.ResolutionFileResolver

All Implemented Interfaces:

FileHandleResolver

public class ResolutionFileResolver
extends java.lang.Object
implements FileHandleResolver

This FileHandleResolver uses a given list of ResolutionFileResolver.Resolutions to determine the best match based on the current Screen size. An example of how this resolver works:

Let's assume that we have only a single ResolutionFileResolver.Resolution added to this resolver. This resolution has the following properties:

• portraitWidth = 1920
• portraitHeight = 1080
• folder = "1920x1080"

One would now supply a file to be found to the resolver. For this example, we assume it is "textures/walls/brick.png". Since there is only a single ResolutionFileResolver.Resolution, this will be the best match for any screen size. The resolver will now try to find the file in the following ways:

• "textures/walls/1920x1080/brick.png"
• "textures/walls/brick.png"

The files are ultimately resolved via the given {baseResolver. In case the first version cannot be resolved, the fallback will try to search for the file without the resolution folder.
