Hello world,

I create a new “Timers” extension: [https://github.com/darzu/arcade-timers](https://github.com/darzu/arcade-timers)  
Early beta.

Sample: [https://makecode.com/\_c57bYTea0RFV](https://makecode.com/_c57bYTea0RFV)

## Blocks

## Examples

#### “After X do” / aka setTimeout:

Oooh. These look nice! I’m curious if there are many implementation differences between your `setTimeout` equivalent and @peli’s recently posted `setTimeout`-sounding block:

> This is a single block extension that allows to schedule code execution after a delay, in the game update. [https://pelikhan.github.io/arcade-clock/](https://pelikhan.github.io/arcade-clock/) [image]

My APIs are integrated into the arcade runtime, eg they will run at the same priority as the “on game update” handler.

Ah. I should probably learn more about this.

Is this documentation still mostly relevant? [https://arcade.makecode.com/developer/game-loop](https://arcade.makecode.com/developer/game-loop) … the version number mentioned in the beginning looks to be a bit behind the current release.

Yes it’s pretty good. This part has not changed much.
