[Suggestion] Colorful Flames

This is a great idea, I will put this on our to-do list!

Good idea. I know that from ARK. Looks really good.

Maybe you could change the light intensity on flames and torches.

I really love it. I hope we are be able to use such features later.

I can't create plugins, or have never tried it.

Basically it would be indeed quite useful if there was a way to access built-in game objects The only problem would be to implement that in a consistent and reliable way... objects like furniture are bound to a chunk, so if the chunk is regenerated (e.g. if the player comes back after walking away), the object prefab would be loaded again (missing any changes you've done to it in the meantime)

But probably it would work if the game always keeps track of all modifications that had been done through the API - if the game then reloads the object prefab, it would have to go through that list again and re-apply all changes. This approach may have some minor performance implications (especially when doing lots of modifications)... but we'll think about adding such a feature

However, in the meantime, you could load the object you're looking for as Prefab: You could load the asset from the game files (for the brazier, it would be PrefabAsset.loadFromGame("Models/Objects/Brazier/brazier1.prefab"); - but you could also get the relevant paths from the definitions). You could then disable the childs manually with prefab.setActive() (the brazier has two childs called "fire" and "light") and add your own, custom childs

This is actually how it works now - I'm creating a new prefab from object prefab path and destroy original object. The thing is that the child count is always zero, so I can't control anything inside brazier prefab (iterating over child list also does nothing since there are always zero childs). Another thing is that while torch prefab don't have flame and light source (it is in deactivated state) the brazier always have both flame and light

Yes, unfortunately you can't iterate over prefab childs (i.e. childs which are part of the prefab asset) The API only provides direct access to childs for user-created game objects (i.e. only elements which were created through the API and added as child to a parent manually). Actually the API isn't aware of the actual prefab asset hierarchy (because prefabs are and other assets are only loaded clientside). This may change in the long run, but we don't have an ETA for that yet...

To overcome this limitation, the Prefab class accepts a path for most methods - you can optionally provide the path to a child element there (i.e. a child which is part of the prefab asset itself). In case of the brazier, the childs are called "fire" and "light", so you could disable them that way:

Prefab prefab = new Prefab(PrefabAsset.loadFromGame("Models/Objects/Brazier/brazier1.prefab"));
prefab.setLocalPosition(player.getPosition());

//Disable fire
prefab.setActive("fire", false);

//Disable light
prefab.setActive("light", false);

player.addGameObject(prefab);

This is a small oversight, basically it doesn't matter too much because the game overrides the state anyway when spawning the prefab
