RAF

FrameRequestCallback

type FrameRequestCallback = float -> unit

createRAF

let createRAF(
    callback: FrameRequestCallback
    ): running: Accessor<bool> * start: VoidFunction * stop: VoidFunction

A primitive for creating reactive window.requestAnimationFrame that is automatically disposed onCleanup.

targetFPS

let targetFPS(
    callback: FrameRequestCallback,
    fps: float | Accessor<float>
    ): FrameRequestCallback

A primitive for wrapping a window.requestAnimationFrame callback function to limit the execution of the callback to the specified number of frames per second.

Keep in mind that limiting FPS is achieved by not executing a callback if the frames are above the defined limit. This can lead to inconsistent frame durations.

createMs

let createMs(
    fps: float | Accessor<float>,
    ?limit: float | Accessor<float>
    ): MsCounter

A primitive that creates a signal counting up milliseconds with a given frame rate to base your animations on.

MsCounter

type MsCounter = interface

member current: int

This calls the MsCounter in the runtime: msCounter().

member reset(): unit

Manually reset the counter.

member running(): bool

Returns if the counter is currently running.

member start(): unit

Restarts the counter if stopped.

member stop(): unit

Stops the counter if running.
