Type Aliases​

RefsProperty​

type RefsPropertyTValue = TValue extends public () ? TReference : never

Type Parameters

Variables​

DEG2RAD​

const DEG2RAD: number = ...

A constant for converting degrees to radians

Examples

RAD2DEG​

const RAD2DEG: number = ...

A constant for converting radians to degrees

Examples

Functions​

beginSlide​

public beginSlidename: string: ThreadGenerator

Parameters

capitalize​

public capitalizeT extends stringvalue: T: CapitalizeT

Type Parameters

  • T extends string

Parameters

createRef​

public createRefT(): ReferenceT

Type Parameters

debug​

public debugpayload: any: void

Logs a debug message with an arbitrary payload.

This method is a shortcut for calling useLogger().debug() which allows you to more easily log non-string values as well.

Examples

Parameters

deprecate​

public deprecateTArgs extends any[]TReturnfn: public ()message: stringremarks?: string: public ()

Mark the given function as deprecated.

Type Parameters

Parameters

  • fn: public ()

    The function to deprecate.

  • message: string

    The log message.

  • remarks?: string

    The optional log remarks.

endPlayback​

public endPlaybackplayback: PlaybackStatus: void

Parameters

endScene​

public endScenescene: Sceneunknown: void

Parameters

endThread​

public endThreadthread: Thread: void

Parameters

errorToLog​

public errorToLogerror: any: LogPayload

Parameters

finishScene​

public finishScene(): void

Mark the current scene as ready to transition out.

Usually used together with transitions. When a scene is marked as finished, the transition will start but the scene generator will continue running.

getContext​

public getContextoptions?: CanvasRenderingContext2DSettingscanvas: HTMLCanvasElement = ...: CanvasRenderingContext2D

Parameters

isProxyEnabled​

public isProxyEnabled(): boolean

Check if the proxy is enabled via the plugin by checking for import.meta.env.VITE_MC_PROXY_ENABLED

The value can either be 'true' of 'false' (as strings) if present, or be undefined if not run from a vite context or run without the MC Plugin.

makeRef​

public makeRefTObjectTKey extends stringnumbersymbolobject: TObjectkey: TKey: ReferenceReceiverTObject[TKey]

Type Parameters

Parameters

makeRefs​

public makeRefsT extends public ()(): RefsPropertyT

Type Parameters

  • T extends public ()

range​

public rangelength: number: number[]
public rangefrom: numberto: number: number[]
public rangefrom: numberto: numberstep: number: number[]

Create an array containing a range of numbers.

Examples

Parameters

  • length: number

    The length of the array.

startPlayback​

public startPlaybackplayback: PlaybackStatus: void

Parameters

startScene​

public startScenescene: Sceneunknown: void

Parameters

startThread​

public startThreadthread: Thread: void

Parameters

useContext​

public useContextcallback: public (): public ()

Provide a function to access the Context2D before the scene is rendered.

Parameters

  • callback: public ()

    The function that will be provided the context before render.

useContextAfter​

public useContextAftercallback: public (): public ()

Provide a function to access the Context2D after the scene is rendered.

Parameters

  • callback: public ()
