Warning: Legacy code ahead

This page has been written for the legacy Sphere 1.x API. While this API is supported in miniSphere, it is generally recommended to use the new Sphere 2 API.

You can mix old and new API functions, but please be aware that Sphere 2 objects are different from Sphere 1 objects, so they cannot be used interchangeably.

This is a definitive reference of the **legacy** Sphere 1.5 API. In other words, the functions that Sphere 1.5 uses in its JavaScript engine.

For the newer Sphere 2 API, please check API:Functions.

Alternatively, the whole Sphere API, sorted by category, with brief descriptions of the functions is available in the API text file mirror itself.

For assistance with using JavaScript itself, consult these links:

Making new function/object pages

Simple steps:

Click a red link.
Place the following code in the empty edit box: {{subst:functemp}} for a new function, or {{subst:objecttemp}} for a new object.
Check the minor edit flag and save.
Click 'edit' at the top of the page to add content.
Try to be objective when writing, and save when you're done.
Remove description from this page, add page link to list at the top of the matching section.

-= Sphere objects =
-Besides the above, Sphere has a set of built-in objects for more generalized use within projects. Most are loaded from external resource files, but a few (Color, ColorMatrix) are defined solely in script and remain only in-memory during the running of the project.
