Unigine::ParticleModifierVector Class

Header: #include <UnigineObjects.h>
Inherits: ParticleModifier

This class is used to represent a particle system modifier, that controls a vector parameter (position, direction, etc.). Modifiers are used to control how various parameters of particle systems change over the particle's life time.

void setConstant ( const Math::vec3 & constant ) #

Sets a new constant vector value for the modifier. In the CONSTANT modifier mode the actual value of the controlled parameter remains equal to this constant throughout the particle's lifetime.

Arguments

  • const Math::vec3 & constant - Constant vector value to be set for the modifier (all components are constant).

Returns the current constant vector value set for the modifier. In the CONSTANT modifier mode the actual value of the controlled parameter remains equal to this constant throughout the particle's lifetime.

Return value

Current constant vector value set for the modifier (all components are constant).
