[ Solved ]Get Sun World Settings?

[Yue]

How can I retrieve the sun from the map to create a night and day effect?

 

[Josh]

The sun will be stored as a directional light in the scene.

Do you have a tag or something similar to get it back?

[Josh]

Just cast each entity in scene->entities to a DirectionalLight. The only one that isn't NULL is the sun.

I'm stuck here.

 

function this:LoadScene(mapName)

        scene = LoadScene(world, mapName)

        mapName = mapName

        Print("[World] Mapa cargado: " .. mapName)

 

        local sun = nil

 

        for i = 0, #scene.entities   do

            local entity = scene.entities[i]

            Print("XXXX"..tostring( entity))

           

            --local light = entity:CastToDirectionalLight()

           -- if light ~= nil then

                --sun = light

               -- break

            --end

        end

       

       

    end

Casting in lua looks like this:

sun = DirectionalLight(entity)

Maybe @Joshdid not yet added it

[Josh]

There is always an easy way to find out what is in the API. Just type the function name into the editor console and press return, and it will tell you the value or type of the variable. When I do this, I can see that DirectionalLight is a function.

[Josh]

@Yue Arrays in Lua start with 1, not 0.

[Yue]

Run but don't get anything back.

 

[Josh]

if sun ~= nil then break end

Put that inside the loop after getting sun.

[Yue]

I'll go to sleep in peace. Today I learned something by brute force, the sun is off in the editor, so that's why nil returned. Thank you all for the patience.

 

function this:LoadScene(mapName)

        scene = LoadScene(world, mapName)

        mapName = mapName

        Print("[World] Mapa cargado: " .. mapName)

 

        local sun = nil

 

        for i = 1, #scene.entities    do

            local entity = scene.entities[i]

         

             sun = DirectionalLight( entity)

 

             if sun ~= nil then break end

         

         

           

        end

 

       sun:SetHidden(true)

       

    end

AI integration could have saved a lot of time here:

fix any errors in this Lua code. Your response should consist only of Lua code. Clearly mark the sections of the code you are changing, and add explanations of your changes in code comments. Do not add any additional information other than pure Lua code.

It makes some comments that make no sense, but it did catch two errors.

function this:LoadScene(mapName)
    scene = LoadScene(world, mapName) -- Changed: Ensure 'scene' is properly defined
    -- mapName = mapName -- Removed: This line is redundant and does nothing
    Print("[World] Mapa cargado: " .. mapName)

    local sun = nil

    for i = 1, #scene.entities do -- Changed: Start loop from 1 instead of 0, as Lua arrays are 1-indexed
        local entity = scene.entities[i]
        local light = DirectionalLight(entity) -- Ensure 'DirectionalLight' is a valid function
    end
end

What if the IDE could send the printed error messages, the stack trace, and the lua code file to Deep Seek for analysis every time a syntax or runtime error occured, and it just automatically corrected the code?
