Applies a translational acceleration to particles over time.
Affector class that applies an acceleration vector to each particle. A popular use case is gravity.
| thor::ForceAffector::ForceAffector | ( | sf::Vector2f | acceleration | ) | [explicit] |
Constructor.
| acceleration | The acceleration vector. The particle's velocity changes by this vector each second. |
| virtual void thor::ForceAffector::Affect | ( | Particle & | particle, |
| sf::Time | dt | ||
| ) | [virtual] |
Affects particles.
| particle | The particle currently being affected. |
| dt | Time interval during which particles are affected. |
Implements thor::Affector.
| static Ptr thor::ForceAffector::Create | ( | sf::Vector2f | acceleration | ) | [static] |
Creates an affector that accelerates particles continuously.
| acceleration | The acceleration vector. The particle's velocity changes by this vector each second. |
