This function returns the facing direction that is manually set using SetFacingDirection.

Syntax

• Vec3 GetFacingDirection()

Returns

This function returns a Vec3 containing the manually set particle facing direction.

Remarks

This function is meant to be used in conjunction with SetFacingDirection, if the particle facing mode is set to billboarded then GetFacingDirection will be of no use. Remember that the view mode must be set to manual direction, see SetViewMode.

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);

    //Create an emitter
    Emitter* emitter = Emitter::Create(1000);
    emitter->SetViewMode(2); //set the view mode to manual facing direction
    emitter->SetFacingDirection(0, 1, 0); //set particles to always face up

    while (true)
    {
        if (window->Closed() || window->KeyDown(Key::Escape)) return false;

        Leadwerks::Leadwerks::Time::Update();
        world->Update();
        world->Render();

        context->SetBlendMode(Blend::Alpha);
        context->DrawText("facing direction: " + (emitter->GetFacingDirection()).ToString(), 2, 2);
        context->SetBlendMode(Blend::Solid);

        context->Sync();
    }
