Is there any plan to add lighting Components inside defold or will it always have to be handled manually?
There used to be some but they were non-functional and have been removed in Editor 2. Maybe they will come back again hopefully if an official lighting model is added.
You can still code your own lights and update your materials with the new light properties yourself.
There is currently no plans to add this but we will add other things that makes it easier to do this in Defold (resource properties, likely to be released in the next release, and multi texturing)
Why not? A lot of games and engines have them, it would really improve the experience as a developer.
Well, for now there is no short term plan to add a Light component. There is however plans to make other things such as configurable resource properties on components (ie replacing textures, materials and more on the fly) as well as a system for multitexturing (ie defining not only a diffuse texture but also normal etc)
Will we still need to send messages to each object to update camera / light positions or will there eventually be a more central way for handling these variables?
