A single GLSL File suitable for loading by the Loader.

These are created when you use the Phaser.Loader.LoaderPlugin#glsl method and are not typically created directly.

For documentation about what all the arguments and configuration options mean please see Phaser.Loader.LoaderPlugin#glsl.

Constructor

new GLSLFile(loader, key, [url], [shaderType], [xhrSettings])

retryAttempts

retryAttempts: number

You can set this value via the Game Config, or you can adjust the LoaderPlugin property at any point after the Loader has started. However, it will not apply to files that have already been added to the Loader, only those added after this value is changed.
