VelocityAffector class
#include <nCine/Graphics/ParticleAffectors.h>
Affector that animates the velocity of a particle.
Linearly interpolates a velocity offset between consecutive VelocityStep entries and adds the resulting amount to the particle's velocity each frame.
Base classes
- class ParticleAffector
- Base class for all particle affectors.
Public types
- struct VelocityStep
- A velocity offset keyed to a normalized particle age.
Constructors, destructors, conversion operators
- VelocityAffector()
- VelocityAffector(VelocityAffector&&) defaulted
- Default move constructor.
- VelocityAffector(const VelocityAffector& other) protected defaulted
- Protected default copy constructor used to clone objects.
Public functions
- auto operator=(VelocityAffector&&) -> VelocityAffector& defaulted
- Default move assignment operator.
- auto clone() const -> VelocityAffector
- Returns a copy of this object.
- void affect(Particle* particle, float normalizedAge) override
- Affects a property of the specified particle using a precomputed normalized age.
- void addVelocityStep(float age, float velX, float velY)
- Appends a velocity step at the specified age.
- void addVelocityStep(float age, Vector2f velocity)
- Appends a vector velocity step at the specified age.
- auto steps() -> SmallVectorImpl<VelocityStep>&
- Returns the array of velocity steps.
- auto steps() const -> const SmallVectorImpl<VelocityStep>&
- Returns the array of velocity steps (read-only).
Function documentation
void nCine::
Appends a velocity step at the specified age.
Steps must be added in ascending age order; an out-of-order step is rejected with a warning.
