Editor Scripting suggestions

[klepto2]

I don't know exactly if this is the right place for this, but feel free to move it where ever you like,

After the debugging fix in the latest release, I have started to experiment with the Lua extension integration.

Some things I noticed:

• Currently, there is no way to dynamically down cast an entity to its derived class, e.g.: Entity → Model
  • This is not supported by sol out of the box, but might be needed later as well for type checking.
  • Currently, you can access all entities in the world, but not determine if it is something other than an entity.
• Some things are not yet accessible for extensions:
  • The objects in the scene (I found out how to add items, not very hard) but I can't find a way to access the already added items in the scene. (using the world property of the program is not very useful because of the first problem (cast/type check) I have mentioned)
• Currently, there are no advanced extensions available, and as I understand that the focus lies on the release on bug fixing I would appreciate some documentation on how to properly script extensions (usage of the Undo/Redo, scene access) 

It would be nice to see some more advanced scripting options soon.

I especially like some of the syntaxes which are available through sol3:

local ent = world:GetEntitiesInArea(min,max)
for i = 1, #ent do
        local e = ent[i]
        local name = getmetatable(e).__type.name -- unfortunatly only returns "UltraEngine::Entity" and nothing else. No way to cast
        Print(name)
end

To downcast just call Model(entity). This works for most types but since it is a function I have to declare there may be some missing.

program:OpenAsset is the only method to open the AssetEditor

How else would it work? Multiple asset windows can be opened, and they are never empty.

The Model.base member is a class that is an asset, though I am not sure if it is exposed to Lua. I don't see it in the documentation...

model.base is now added to the Lua API and can be used as the asset to open a model.

This is exactly what i meant. I guessed it should be only this one. 

Is the model.base already exposed in the editor? I can't access it after the latest update. 

This is what i have tried so far:

model.base (not available)

model:GetBase() (not available)

Asset(model) or Asset(model.base) (not working)

Sorry about that. This will work now in build 246:

mdl = LoadModel(nil, "models/developer/crate/crate.gltf") program:OpenAsset(mdl.base)

Alternatively, you can just do this:

program:OpenAsset("models/developer/crate/crate.gltf")

that works.

I noticed, that sometimes when using CreateDir in the script, the assetbrowser is not updating the folder structure. Could you add a method which refreshes the nodes, or something like assetbrowser:RefreshFolder(folder) ?

It should detect a file system event. If not it is a bug...

A simple test works correctly:

CreateDir("Models/test")
CreateDir("Models/test/a/b/c", true)
