This function returns the emitter's emission volume, the area in which a particle may spawn.

Syntax

• Vec3 GetEmissionVolume()

Returns

This function returns a Vec3 containing the emitter's emission volume.

Example

#include "Leadwerks.h"

using namespace Leadwerks;

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

    camera->Move(0, 0, -3);
    Light* light = DirectionalLight::Create();
    light->SetRotation(35, 35, 0);

    //Create an emitter
    Emitter* emitter = Emitter::Create(100);
    float sz = 1.0;
    emitter->SetEmissionVolume(sz, sz, sz);

    while (true)

        Leadwerks::Leadwerks::Time::Update();
