## Member Function Documentation

virtual const core::vector3df& irr::scene::IParticleGravityAffector::getGravity | ( |  | ) | const`[pure virtual]`

Get the direction and force of gravity.

virtual f32 irr::scene::IParticleGravityAffector::getTimeForceLost | ( |  | ) | const`[pure virtual]`

Get the time in milliseconds when the gravity force is totally lost.

virtual E_PARTICLE_AFFECTOR_TYPE irr::scene::IParticleGravityAffector::getType | ( |  | ) | const`[inline, virtual]`

Get emitter type.

Implements irr::scene::IParticleAffector.

References irr::scene::EPAT_GRAVITY.

virtual void irr::scene::IParticleGravityAffector::setGravity | ( | const core::vector3df & | gravity | ) | `[pure virtual]`

Set the direction and force of gravity in all 3 dimensions.

virtual void irr::scene::IParticleGravityAffector::setTimeForceLost | ( | f32 | timeForceLost | ) | `[pure virtual]`

Set the time in milliseconds when the gravity force is totally lost.

At that point the particle does not move any more.
