ParticleCtrlEmissionDemo

Overview

This demo controls the emission volume of particles. This demo uses the demo library, demo::ParticleEffect class, and demo::ParticleNode class.

How to Use

• Demo-specific operations
• R Button: Increases the emission volume.
• L Button: Decreases the emission volume.
• Common Operations
• Slide pad: Rotate the camera
• Slide pad + A Button: Move the camera back and forth
• Slide pad + B Button: Move the camera in parallel
• Slide pad + Y Button: Move the camera up and down
• X Button: Reset the camera position
• START Button: Restart the demo.

Description

Particle emission volume can be dynamically controlled using the nw::gfx::ResParticleEmitterParameter::SetEmissionRatio method in the nw::gfx::ResParticleEmitterParameter class.

{
    nw::gfx::ResParticleEmitterParameter resEmitterParameter = particleEmitter->GetResParticleEmitterParameterCopy();
    resEmitterParameter.SetEmissionRatio(1.f);
}

Within demo code, emission volume is controlled using the SetEmissionRatio() method in the ParticleNode class.
