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

• void SetLightQuality(const int 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

#include "Leadwerks.h"

using namespace Leadwerks;

SpotLight* light = NULL;
int main(int argc, const char *argv[])
{
    Leadwerks::Window* window = Leadwerks::Window::Create();
    Context* context = Context::Create(window);
    World* world = World::Create();
    Camera* camera = Camera::Create();
    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
    Model* 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)
        {
            if (window->Closed() || window->KeyDown(Key::Escape)) return false;

            float delta = (window->KeyDown(Key::Up) - window->KeyDown(Key::Down)) * Leadwerks::Time::GetSpeed() * 0.1;
            Vec2 angles = light->GetConeAngles();
            angles.x += delta;
            angles.x = Math::Clamp(angles.x, 1, 45);
            angles.y = angles.x * 0.75;
            light->SetConeAngles(angles.x, angles.y);

            Leadwerks::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, 20);

            context->Sync();

        }
    return 0;
