GetLightQuality
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
Returns
This function returns an integer indicating the light quality:
0: Low
1: Medium
2: High
The engine normally defaults to medium quality, but will use low quality if Intel graphics are 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()
