ParticleType Class Reference

Detailed Description

Represents a particle type. A particle type serves as a definition of the particles on the initial state of a particle simulation.

A particle cloud contains one or more particle type(s). All particle types in a scene can be found under Scene.Particles container.

Member Function Documentation

bool IsA ( siClassID  in_ClassID ) const [virtual]

Returns true if a given class type is compatible with this API class.

in_ClassID class type.
true if the class is compatible, false otherwise.

Reimplemented from Property.

siClassID GetClassID ( ) const [virtual]

Returns the type of the API class.

The class type.

Reimplemented from Property.

ParticleType& operator= ( const ParticleType in_obj )

Creates an object from another object. The newly created object is set to empty if the input object is not compatible.

in_obj constant class object.
The new ParticleType object.
ParticleType& operator= ( const CRef in_ref )

Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.

in_ref constant class object.
The new ParticleType object.

Reimplemented from Property.

LONG GetID ( ) const

Returns the scene index for this particle type, which corresponds to the index of this particle type under the Scene.Particles container.

The ParticleType ID.
CStatus AddAttribute ( const CString in_name,
XSI::siParticleAttributeType  in_type 
) const

Adds a new user-defined attribute to this particle type. You must specify a type (ParticleAttribute.GetAttributeType) and a unique name for the new attribute. This function fails if another user-defined attribute with the same name exists.

in_name name of the defined attribute
in_type type of the defined attribute
CStatus::OK success
CStatus::Fail other failure
CStatus::InvalidArgument if in_type is siPAUndefined
CStatus RemoveAttribute ( const CString in_name ) const

Removes a user-defined attribute from this particle type by specifying the name.

in_name name of the attribute to remove.
CStatus::OK success
CStatus::Fail other failure
CStatus::False the attribute of name in_name was not found on the ParticleType.
CStringArray GetAttributeNames ( ) const

Returns an array containing the names of all user-defined attributes for this particle type.

Array of custom attribute names.
XSI::siParticleAttributeType GetAttributeType ( const CString in_name ) const

Returns the data type of the specified attribute. If no attribute matches the specified name, it returns siPAUndefined.

in_name name of the attribute to remove.
Type of a given attribute.
siPAUndefined if no match is found
