This function manually sets a direction that all particles will face.

Syntax

• void SetFacingDirection(float x, float y, float z)

Remarks

The most common application of this function is to draw particles on the ground facing up. Make sure to change the view mode to manual facing direction 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();
    }
}
