• Create and register a new ScriptType. It returns new class type (constructor function), which is auto-registered to ScriptRegistry using its name. This is the main interface to create Script Types, to define custom logic using JavaScript, that is used to create interaction for entities.

    Parameters

    • name: string

      Unique Name of a Script Type. If a Script Type with the same name has already been registered and the new one has a swap method defined in its prototype, then it will perform hot swapping of existing Script Instances on entities using this new Script Type. Note: There is a reserved list of names that cannot be used, such as list below as well as some starting from _ (underscore): system, entity, create, destroy, swap, move, scripts, onEnable, onDisable, onPostStateChange, has, on, off, fire, once, hasEvent.

    • Optional app: AppBase

      Optional application handler, to choose which ScriptRegistry to add a script to. By default it will use Application.getApplication() to get current AppBase.

    Returns typeof ScriptType

    A class type (constructor function) that inherits ScriptType, which the developer is meant to further extend by adding attributes and prototype methods. Returns null if there was an error.

    Example

    var Turning = pc.createScript('turn');

    // define 'speed' attribute that is available in Editor UI
    Turning.attributes.add('speed', {
    type: 'number',
    default: 180,
    placeholder: 'deg/s'
    });

    // runs every tick
    Turning.prototype.update = function (dt) {
    this.entity.rotate(0, this.speed * dt, 0);
    };
