This function sets the rotation speed in degrees per second of released particles.

Syntax

• void SetRotationSpeed(float speed=0.0f)

Parameters

• peed: - Specifies the rotation speed in degrees per second.

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);
    World* world = World::Create();
    Camera* camera = Camera::Create();
    camera->Move(0, 0, -3);

    float rotationspeed = 90;

    //Create an emitter
    Emitter* emitter = Emitter::Create(500);
    Material* material = Material::Load("Materials/Effects/spark.mat");
    if (material)

        emitter->SetMaterial(material);
        material->Release();
    }

    emitter->SetRotationSpeed(rotationspeed);
    emitter->SetVelocity(0, 0, 0, 0); //set base velocity to 0

    while (true)
