# Interface: operator

The operator Interface is exposed in all Particle Flow Operator Classes.

Methods:

    <bool><PF_Operator>.proceed <IObject>container <time>timeStart <time>timeEnd <object>particleSystem <node>particleSystemNode <node>actionNode <Interface>integrator

Proceeds the Operator. Lets you calls the Proceed method of an Operator from inside a Script_Operator’s on Proceed... handler.

For an example, see Speed Operator in Script Operator Example

This Interface is available in:

Birth : Helper Birth_Group : Helper BirthGrid : Helper Birth_Paint : Helper Birth_Script : Helper Birth_Texture : Helper Cache : Helper Cache_Disk : Helper Cache_Selective : Helper Camera_Culling : Helper Camera_IMBlur : Helper | Data_Icon : Helper Data_Operator : Helper DeleteParticles : Helper displayParticles : Helper Force : Helper Go_To_Rotation : Helper Initial_State : Helper Keep_Apart : Helper mapping : Helper Material_Dynamic : Helper Material_Frequency : Helper | Material_Static : Helper mP_Buoyancy : Helper mP_Drag : Helper mP_Force : Helper mP_Shape : Helper mP_Solvent : Helper mP_Switch : Helper Notes : Helper Position_Icon : Helper Position_Object : Helper renderParticles : Helper | rotation : Helper scaleParticles : Helper Script_Operator : Helper shapeStandard : Helper Shape_Facing : Helper Shape_Instance : Helper Shape_Mark : Helper speed : Helper SpeedByIcon : Helper Speed_By_Surface : Helper Spin : Helper
