SetLightQuality

This function sets the world's light quality setting. This will effect the softness of shadow edges, and will also affect how far in the distance directional light shadows are visible.

Syntax

SetLightQuality(number quality)

Parameters

quality: allowed values are 0, 1, and 2, with 0 being lowest quality and 2 being the highest. The engine normally defaults to a setting of 1 (medium) quality, but will use 0 if an integrated graphics chip is detected.

Example

--Create a window
window = Window:Create()
context = Context:Create(window)
world = World:Create()
camera = Camera:Create()
camera:SetRotation(35,0,0)
camera:Move(0,0,-8)

--Create a model
local model = Model:Box() 
model:SetColor(0.0,1.0,0.0) 
model:SetScale(10,1,10) 
        
light = SpotLight:Create() 
light:SetPosition(0,3,0) 
light:Turn(90,0,0) 
light:SetConeAngles(10,7.5) 
                
world:SetLightQuality(1)

while true do        
        if window:Closed() or window:KeyHit(Key.Escape) then return false end

        local delta = ((window:KeyDown(Key.Up)and 1 or 0) - (window:KeyDown(Key.Down) and 1 or 0)) * Time:GetSpeed() * 0.1 
        local angles = light:GetConeAngles() 
        angles.x = angles.x + delta 
        angles.x = Math:Clamp(angles.x,1,45) 
        angles.y = angles.x * 0.75 
        light:SetConeAngles(angles.x,angles.y) 

        Time:Update()
        world:Update()
        world:Render()

        context:SetBlendMode(Blend.Alpha) 
        context:DrawText("Cone angles: "..angles:ToString(),2,2) 
                 context:DrawText("Light quality: "..world:GetLightQuality(),2,25) 

        context:Sync()
