Class

Source: ParticleEmitter.h

Inherits from: Entity

Description

Manages a pool of particles to create visual effects.

Participates in the scene update/draw loop. Uses a fixed-size array for particles to avoid dynamic allocation during runtime.

Methods

void update(unsigned long deltaTime)

Description:

Updates all active particles. Applies physics (gravity, friction) and updates lifetime.

Parameters:

• deltaTime: Time elapsed since last frame.

void draw(pixelroot32::graphics::Renderer& renderer)

Description:

Renders all active particles.

Parameters:

• renderer: The renderer instance.

void burst(pixelroot32::math::Vector2 position, int count)

Description:

Emits a burst of particles from a specific location.

Parameters:

• position: Emission origin.
• count: Number of particles to spawn.

inline uint16_t lerpColor(uint16_t c1, uint16_t c2, pixelroot32::math::Scalar t)

Description:

Linear interpolation between two 16-bit RGB565 colors.

Parameters:

• c1: Start color.
• c2: End color.
• t: Interpolation factor (0.0 - 1.0).

Returns: Interpolated RGB565 color.
