API docs

This is a summary page comparing all the APIs. Click on API name to see its documentation. See what is an API.

Go to the Starter Worlds page to see Starter Worlds for all APIs on one page.

These APIs use specific versions of third-party libraries. These APIs will not change in the future, so that all runs will always work. Rather, new APIs will be added.

"Ancient Brain" APIs

The following APIs include third-party libraries and a useful Ancient Brain framework to make writing Worlds easy and short.

These APIs are useful for writing JS Worlds for this site:


API Version Uses canvas Graphics libraries AB framework Worlds using this API Starter Worlds
Three (AB) 2.0 Yes Three.js Yes 184 Worlds Starter Worlds
Physics (AB) 1.0 Yes Three.js, Physijs Yes 104 Worlds Starter Worlds
P5 (AB) 1.0 Yes P5 Yes 33 Worlds Starter Worlds
Canvas (AB) 1.0 Yes None Yes 44 Worlds Starter Worlds

"Plain" APIs

The following APIs include third-party libraries and nothing else (no useful Ancient Brain framework). The World author has to write everything themselves.

These APIs are useful for porting JS Worlds to this site unchanged:


API Version Uses canvas Graphics libraries AB framework Worlds using this API Starter Worlds
Three 2.0 Yes Three.js No 26 Worlds Starter Worlds
Physics 1.0 Yes Three.js, Physijs No 7 Worlds Starter Worlds
P5 1.0 Yes P5 No 1080 Worlds Starter Worlds
Canvas 1.0 Yes None No 6 Worlds Starter Worlds
Webpage 1.0 No None No 46 Worlds Starter Worlds

Earlier version APIs

Worlds with an earlier version of the API will run fine. Just that a later version of the API exists. These earlier APIs will exist forever, so the Worlds will run forever. And you can go on using the earlier API forever.

Over time, we expect most Worlds on this site to have APIs in this section rather than in the "latest version" section. But this is not a problem.


API Version Uses canvas Graphics libraries AB framework Worlds using this API Starter Worlds
Three (AB) (1.0) 1.0 Yes Three.js Yes 1021 Worlds None
Three (1.0) 1.0 Yes Three.js No 1 World None
