| _type_ | |
| Type of effect : defines the type of effect among the following :
- EFFECT_CONSTANT : This effect allows to apply a constant force on particles. It can therefore be useful for creating gravity or wind.
| vectors | meaning |
| '_vectorA_' | Force applied on the particles |
| '_vectorB_' | - |
| '_vectorC_' | - |
- EFFECT_ELECTRIC : This effect simulates an electrically charged entity. This charge creates an electric field which acts on the particles according to their polarity.
Warning : this effect applies only to particles which do not have a null value for their mass.
| vectors | meaning |
| '_vectorA_' | Position of the electric charge, expressed in the global space |
| '_vectorB_' | First coordinate : value of the electric charge |
- EFFECT_MAGNETIC : This effect simulates a uniform magnetic field. This field creates a force whose direction is given by the vector product between the direction of the magnetic field and the velocity of the particle.
Warning : this effect applies only to particles which do not have a null value for their mass.
| vectors | meaning |
| '_vectorA_' | Magnetic field |
| '_vectorB_' | First coordinate : polarity of the field |
- EFFECT_CHAOTIC0 : This effect attributes a completely random and independent force to each particle. A maxima and a minima can however be specified :
| vectors | meaning |
| '_vectorA_' | Minimum force |
| '_vectorB_' | Maximum force |
- EFFECT_CHAOTIC1 : This effect is similar to that above except that the force is identical for all the particles.
- EFFECT_HELICOID : This effect gives the particles a helicoidal trajectory.
| vectors | meaning |
| '_vectorA_' | Direction of the helicoïdal trajectory |
| '_vectorB_' | First and second coordinate : x and y radius
Third coordinate : rotational speed |
|
| _vectorA_ | |
| Depends on the '_type_' parameter. |
| _vectorB_ | |
| Depends on the '_type_' parameter. |
| _vectorC_ | |
| Reserved for future effects.. |
