Effect

INTRODUCTION

The Effect module allows you to access all the data of particle effects. An effect can modify a mesh object using particles, where vertex of the mesh emits particles, which can themselves emit new particles.

In the Blender internals, the effect object is just a placeholder for the particle effect. Prior to v2.39 build and wave effects were also supported by Blender, and the Python API supported all three types of effects. They were removed in v2.39 when the build and wave modifiers were implemented.

Example:

 import Blender
   listffects = Blender.Effect.Get()
   print listeffects
   eff = listeffects[0]
   #we suppose the first effect is a build effect
   print eff.getLen()
   eff.setLen(500)

New(name)

source code

Creates a new particle effect and attaches to an object.

Parameters:

name (string) - The name of object to associate with the effect. Only mesh objects are supported.

Returns: Blender Effect

the new effect

Get(name=None, position=None)

source code

Get an Effect from Blender.

Parameters:

name (string) - The name of object linked to the effect.
position (int) - The position of the effect in the list of effects linked to the object.

Returns: Blender Effect or a list of Blender Effects

It depends on the 'objname, position' parameters:

(): A list with all Effects in the current scene;
(name): A list with all Effects linked to the given object;
(name, position): The Effect linked to the given object at the given position

Flags

The particle effect flags. Values can be ORed.

SELECTED: The particle effect is selected in the UI. (Read-only)
BSPLINE: Use a B-spline formula for particle interpolation
STATIC: Make static particles
ANIMATED: Recalculate static particles for each rendered frame
VERTS: Emit particles from vertices
FACES: Emit particles from faces
EVENDIST: Use even distribution based on face area (requires FACES)
TRUERAND: Use true random distribution based on face area (requires FACES)
UNBORN: Make particles appear before they are emitted
DIED: Make particles appear after they have died
EMESH: Render emitter mesh

Type:: read-only dictionary

SpeedTypes

The available settings for selecting particle speed vectors. Only one setting is active at a time.

INTENSITY: Use texture intensity
RGB: Use RGB values
GRADIENT: Use texture gradient
