Public Member Functions
	ParticleSystem ()
	Constructs the system and registers component callbacks.
void	Update (const float deltaT) override
	Updates all active particles and spawns new ones.
void	Draw () const override
	Renders all visible particles.

Static Public Member Functions
static void	Burst (const Entity entity, u32 count)
	Instantly spawns a burst of particles.
static void	Stop (const Entity entity)
	Stops automatic spawning on the emitter.
static void	Play (const Entity entity)
	Resumes automatic spawning on the emitter.

Detailed Description

Updates and draws particles emitted by entities.

Requires entities to have a Component::ParticleEmitter and a std::vector<Component::Particle>. Handles spawning, physics, aging, and texture‑sorted rendering.

Member Function Documentation

Burst()

void ParticleSystem::Burst ( const Entity entity, u32 count )

static

Instantly spawns a burst of particles.

Parameters

entity	Entity holding the ParticleEmitter.
count	Number of particles to spawn.

Does nothing if entity lacks ParticleEmitter or Transform.

Draw()

void ParticleSystem::Draw ( ) const

overridevirtual

Renders all visible particles.

Interpolates color and size based on age/lifetime. Uses DrawTexturePro if a valid texture is provided, otherwise falls back to circles.

Reimplemented from System.

Play()

void ParticleSystem::Play ( const Entity entity )

static

Resumes automatic spawning on the emitter.

Parameters

entity

Entity with ParticleEmitter.

Stop()

void ParticleSystem::Stop ( const Entity entity )

static

Stops automatic spawning on the emitter.

Parameters

entity

Entity with ParticleEmitter.

Update()

void ParticleSystem::Update ( const float deltaT )

overridevirtual

Updates all active particles and spawns new ones.

Parameters

deltaT

Time since last update (seconds).

• Applies velocity, gravity, angular velocity and aging.
• Removes expired particles.
• If emitter is playing, spawns particles at the given rate.
• Marks sort dirty when particles change.

Implements System.
