xScal Scaleform API

Version 0.4.34

Functions xScal installs on the Scaleform code object, __SFCodeObj, in Fallout 76 menus. SWF mods call them from ActionScript 3.

The SWF creates the object, usually as this.stage.__SFCodeObj = {}. When the SWF first uses it, xScal installs three members on it:

Results described as String (JSON) are Strings; parse them with JSON.parse before use. The field tables list the parsed object.

Wrap xScal access in try/catch so the mod keeps working when xScal is missing or the game build is not supported:

try {
    var result:* = __SFCodeObj.call("someFunctionName");
} catch (error:Error) {
    // xScal is missing or the function is not available.
}
