Get the path to a demo resource — raylibr

The demos use textures, fonts, sounds, shaders and a 3D model that are not part of the installed package, to keep it small. The first time a resource is needed it is downloaded from the raylibr GitHub repository into a cache directory (see tools::R_user_dir()), and later calls use the cached copy.

Usage

raylibr_resource(name)

Arguments

name: Path of a resource relative to the resource directory, e.g. "space.png" or "model/grayscale.fs". A directory such as "beatbox-samples" gives all resources in it.

Value

The full path to the resource file or directory.

Details

Resources are looked up in this order:

The package's demo_resources directory, which the webR build includes.
The directory in the RAYLIBR_ASSETS environment variable, if set, e.g. the assets directory of a raylibr checkout.
The cache, downloading the resource first if needed.

Examples

if (FALSE) { # interactive()
texture_file <- raylibr_resource("space.png")
shader_dir <- raylibr_resource("model")
list.files(shader_dir)
}
