lookat component doesn't work with spotlight

[FrederickDesimpel]

A spotlight entity doesn't orient itself with a lookat component.

Looks like the threejs spotlight has a .target object by itself. That also explains why you can't set a spotlight's orientation.

Either the orientation and lookat components will have to take this into account ( which would nicely abstract this away from the user), or an additional component that sets this target is required.

Or maybe the light system can keep track of them.

been playing a bit with a quick spottarget component... if the spotlight.target is added as a child of the light, and it's pos set to 0 0 -1 orientation works as expected ( with the spot pointed along it's -z axis)

I've been having some of these same issues when using SpotLight from THREE, in general. There seems to be a lot of confusion and discussion about using targets and both @BenJenkinson and @WestLangley left comments detailing a history of these issues here and here, respectively.

I don't know if that's going to be of any help, however.

by adding the light.target to a given object, you get tracking for free :-)

I'm almost done with a component for (spot) light targets. Will have to check if it works for directional lights too, which also have a .target.

@FrederickDesimpel Would love if you could add a target property (type selector) for the light component.

[FrederickDesimpel]

I'll look into it. To have all the options you need a seperate component, but maybe the basics of it can be included in the light component yes.

Maybe tagetobject (selector) and a targetoffset, so you can also give a coordinate in worldpos (relative to scene if you don't specify an object.

And have it default to be added to the light itself, with an offset of (0 0 -1), so it looks down -Z ? and regular rotation works

been a while i worked on that... will have to see if all that can be added to light component in a clear way

All that being said, there is also still this issue

[FrederickDesimpel]

or scratch that... just being able to set the target object is sufficient. You can always create an a-entity , hook that up and set the world position or any offset with that.

Works like a charm now: #1728

spotlight.target added, thanks!
