BABYLON.PointerEventTypes.POINTERTAP is triggered independently if the user clicked in a mobile device, or a computer, that’s ok but there is any chance to know if the user pressed left or right mouse click on PC?

Thank you in advance.

It seems these **PointerEventTypes** are not available yet in the Babylon API.  
You could use the `event.button`-property:

```
 scene.onPointerObservable.add((pointerInfo) => {
		switch (pointerInfo.type) {
			case BABYLON.PointerEventTypes.POINTERTAP:
                switch (pointerInfo.event.button) {
                    case 0: 
                        console.log("LEFT");
                        break;
                    case 1: 
                        console.log("MIDDLE");
                        break;
                    case 2: 
                        console.log("RIGHT");
                        break;
                }
            break;
        }
    });

```

Consider that `event.which` property also works, but is **deprecated**!

It seems that pointerInfo.event.button returns a number but thank you so much!

Did you try the provided code above? 🤔

Thats why I used a switch clause 😉  
You have to interpret the returned numbers with some sort of condition!

> **[MouseEvent.button](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/button)**
>
> The MouseEvent.button read-only property indicates which button was pressed on the mouse to trigger the event.

The PointerEventTypes are also just static constants, containing a number (like Enums)

Sorry my bad! I just copied pointerInfo.event.button and compared with “LEFT” 🙄
