This function sets a light's range. You can retrieve the light range with the Camera::GetRange() function.

Syntax

• void SetRange(const float farrange)
• void SetRange(const float nearrange, const float farrange)

Parameters

• nearrange: the distance of the near plane of the shadowmap projection.
• farrange: the distance at which the light stops having any visible effect.

Example

#include "Leadwerks.h"

using namespace Leadwerks;

Light* 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();
    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 = PointLight::Create();
        light->SetPosition(0,1,0);

    while (true)
    {
        if (window->Closed() || window->KeyDown(Key::Escape)) return false;
        
        float deltarange = (window->KeyDown(Key::Up) - window->KeyDown(Key::Down)) * Leadwerks::Time::GetSpeed() * 0.1;
        float range = light->GetRange().y;
        range += deltarange;
        range = Math::Max(range,0.7);
        light->SetRange(range);
        
        Leadwerks::Time::Update();
        world->Update();
        world->Render();
        
        context->SetBlendMode(Blend::Alpha);
        context->DrawText("Light range: "+String(light->GetRange(.y)),2,2);
        
        context->Sync();
    }
    return 0;
