Get/set metatable in GDScript

[OvercookedBeef]

Hi, I'm wondering how I set a metatable for a LuaTable in GDScript. In Lua, it's done with the getmetatable and setmetatable functions, but I don't see an equivalent in GDScript.

Thanks!

Right now there's no mechanism for that in GDScript. We should totally implement it!

What you can do for now is open the LUA_BASE library in your LuaState, then invoke getmetatable and setmetatable functions directly, like this:

var lua = LuaState.new()
lua.open_libraries()

var some_table = lua.create_table()
var metatable = lua.globals.getmetatable.invoke(some_table)
assert(metatable == null)

lua.globals.setmetatable.invoke(some_table, some_table)	
metatable = lua.globals.getmetatable.invoke(some_table)
assert(metatable == some_table)

Just created Issue #112 to track the metatable feature request.

Hey @OvercookedBeef, so I implemented LuaTable.get_metatable and LuaTable.set_metatable methods that can be called from GDScript, you can download the newly released version 0.5.0 to use these new methods!
