Load models
The simplest way is the model= URL parameter.
Aliases
Play supports a small alias set for demo convenience:
raj(Rajagopal2015)humanoidhumanoid100cardssensor
Examples:
/index.html?model=raj
/index.html?model=cards
Paths under model/
You can also pass a relative MJCF path under model/ (or local_model/ for
local-only files):
/index.html?model=model/cards/cards.xml
If you omit the .xml suffix, Play adds it.
Assets and file references
The default loader supports relative, local file references that can be bundled from the static host (meshes, textures, etc).
Remote or absolute file references are intentionally rejected by the default loader. If you need custom asset handling (remote fetch, authenticated endpoints, custom mapping), use the developer API:
host.backend.loadXmlBundle(...)
See JavaScript API for backend methods.
