Confetti::PointParticle::PointParticle	(	float	lifetime,
		float	age,
		glm::vec3 const &	position,
		glm::vec3 const &	velocity,
		glm::vec4 const &	color
	)

velocity	Velocity at birth.
color	Color at birth.

Member Function Documentation

draw()

void Confetti::PointParticle::draw ( std::shared_ptr< Vkx::Device >  device ) const

overridevirtual

Draws the particle.

Note

This method must be overridden.

Implements Confetti::Particle.

update()

bool Confetti::PointParticle::update ( float  dt )

overridevirtual

Updates the particle. Returns true if the particle was reborn.

Parameters

dt	The amount of time that has passed since the last update.

Note

Methods overriding this method must call this first in order to determine the particle's age and if it has been reborn or not.

Reimplemented from Confetti::Particle.
