This function returns which view mode is currently set.

Syntax

• int GetViewMode()

Returns

This function returns an integer ranging between 0 and 4 containing the specified view mode.

Remarks

0 = billlboard - In this mode each particle will always face the camera.
1 = lock Y-axis - particles will rotate to face the camera in every direction except along the Y-axis.
2 = manual facing direction - particles will always face the direction specified by SetFacingDirection

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, -1, -1);
    camera->SetRotation(-45, 0, 0);

    int viewmode = 0;

    //Create an emitter
    Emitter* emitter = Emitter::Create(100);
    emitter->SetViewMode(viewmode); //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();

        //detect key hits to switch view modes
        if (window->KeyHit(Key::Up) && viewmode < 2)
        {
            ++viewmode;
            emitter->SetViewMode(viewmode);
        }
        else if (window->KeyHit(Key::Down) && viewmode > 0)
        {
            --viewmode;
            emitter->SetViewMode(viewmode);
        }

        context->SetBlendMode(Blend::Alpha);

        {
        case 0:

            break;
        case 1:

            break;
        case 2:
