Hello!

I have two `x` and `y` tilemap positions. (A player and a chest the player wants to find.) I want to get the angle between these two tilemap positions.

All I know is that I need to do something like:

```auto
tan(angle) = (chest_x - player_x) / (chest_y - player_y)

```

I need to find `angle`. (Degrees preferably, because I want to make a compass)

Does anyone have code or an idea on how to get `angle` out of the equation I supplied? Or am I completely wrong?

You’re looking for the `atan2` function.

> **[Math.atan2()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/atan2)**
>
> The Math.atan2() function returns the angle in the plane (in radians) between the positive x-axis and the ray from (0,0) to the point (x,y), for Math.atan2(y,x).

Here’s a demo with a duck and some pizza. 🙂

I had a conversation in another thread where I discussed some trig basics: [Game Math](https://forum.makecode.com/t/game-math/2934)

As always, if you have any questions, just holler!
