This function gets the outer and inner cone angles of a spotlight.

Syntax

• Vec2 GetConeAngles()

Returns

The spotlight outer and inner cone angles in the X and Y components of the returned Vec2, respectively.

Example

#include "Leadwerks.h"

using namespace Leadwerks;
int main(int argc, const char *argv[])
{
    Leadwerks::Window* window = Leadwerks::Window::Create();
    Context* context = Context::Create(window);

    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);

    SpotLight* light = SpotLight::Create();
    light->SetPosition(0, 3, 0);
    light->Turn(90, 0, 0);
    light->SetConeAngles(10, 7.5);

        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();
