Can A-frame 'look-at' component look at the default camera?


Can A-frame 'look-at' component look at the default camera?



Is it possible to get the a-frame look-at component to look at the default camera? Since it does not have an ID or a class by default I don't know how to target it.


look-at



I have tried adding [camera] as the selector value as per the docs like so;


[camera]


<a-text
value="Look at test"
look-at="[camera]">
</a-text>



but it does not seem to work for me. I feel I am missing something obvious here.



Any help appreciated

What you are doing is correct, but at the time the look-at component is initialized, the camera is not yet on the scene.


look-at



Try creating a component, which will wait until the scene is loaded,


this.el.sceneEl.addEventListener("loaded", (e)=>{....



or at least for window.onload.


window.onload



Check it out here.





Thank you Piotr, that does work. It seems a shame you cannot use the component in that way without writing a script. Thanks for the explanation. If anyone is looking for a way to do this without writing a script, this similar component will do it github.com/blairmacintyre/aframe-look-at-billboard-component

<a-text value="Look at test" look-at="#cam"></a-text>
<a-camera id="cam"></a-camera>



this should work.....





Hi Karan, thanks for your answer but that does not work, the default camera does not have an ID. I have just found another very similar component that can look at the default camera github.com/blairmacintyre/aframe-look-at-billboard-component. I'm not going to post that as an answer just in case there is a way to do it with the original mentioned in the question.
