This function determines a particle's starting or ending color.

Syntax

• void SetParticleColor(float r, float g, float b, const float & a, int mode)

Parameters

• r: - a float between 0.0 and 1.0 stating how red a particle should be.
• g: - a float between 0.0 and 1.0 stating how green a particle should be.
• b: - a float between 0.0 and 1.0 stating how blue a particle should be.
• a: - a float between 0.0 and 1.0 stating the alpha value, 0 being transparent and 1 being fully opaque.
• mode: - states whether the initial or final color is being set. 0 = starting color, 1 = final color.

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(50);
    emitter->SetParticleColor(1, 0, 0, 1, 0); //inital color: red
    emitter->SetParticleColor(0, 1, 0, 1, 1); //final color: green
    
    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("Initial Color: " + (emitter->GetParticleColor(0)).ToString(), 2, 2);
        context->DrawText("Final Color: " + (emitter->GetParticleColor(1)).ToString(), 2, 22);
        context->SetBlendMode(Blend::Solid);
        
        context->Sync();
    }
