Public Member Functions

ParticleRendererAlphaMode getAlphaMode ()
bool getIgnoreScale ()
 Returns the "ignore scale" flag. See set_ignore_scale().
GeomNode getRenderNode ()
 Query the geomnode pointer.
NodePath getRenderNodePath ()
 Query the geomnode pointer.
float getUserAlpha ()
 gets alpha for "user" alpha mode
 output (ostream out)
 Write a string representation of this instance to <out>.
 setAlphaMode (ParticleRendererAlphaMode am)
 setColorBlendMode (Mode bm, Operand oa, Operand ob)
 sets the ColorBlendAttrib on the _render_node
 setColorBlendMode (Mode bm, Operand oa)
 sets the ColorBlendAttrib on the _render_node
 setColorBlendMode (Mode bm)
 sets the ColorBlendAttrib on the _render_node
 setIgnoreScale (bool ignore_scale)
 Sets the "ignore scale" flag. When this is true, particles will be drawn as if they had no scale, regardless of whatever scale might be inherited from above the render node in the scene graph.
 setUserAlpha (float ua)
 sets alpha for "user" alpha mode
 write (ostream out, int indent)
 Write a string representation of this instance to <out>.
 write (ostream out)
 Write a string representation of this instance to <out>.

Member Function Documentation

bool getIgnoreScale ( )

Returns the "ignore scale" flag. See set_ignore_scale().

GeomNode getRenderNode ( )

Query the geomnode pointer.

NodePath getRenderNodePath ( )

Query the geomnode pointer.

float getUserAlpha ( )

gets alpha for "user" alpha mode

output ( ostream  out)

Write a string representation of this instance to <out>.

setColorBlendMode ( Mode  bm,
Operand  oa,
Operand  ob 
)

sets the ColorBlendAttrib on the _render_node

setColorBlendMode ( Mode  bm,
Operand  oa 
)

sets the ColorBlendAttrib on the _render_node

setColorBlendMode ( Mode  bm)

sets the ColorBlendAttrib on the _render_node

setIgnoreScale ( bool  ignore_scale)

Sets the "ignore scale" flag. When this is true, particles will be drawn as if they had no scale, regardless of whatever scale might be inherited from above the render node in the scene graph.

This flag is mainly useful to support legacy code that was written for a very early version of Panda, whose sprite particle renderer had a bug that incorrectly ignored the inherited scale.

setUserAlpha ( float  ua)

sets alpha for "user" alpha mode

write ( ostream  out,
int  indent 
)

Write a string representation of this instance to <out>.

write ( ostream  out)

Write a string representation of this instance to <out>.
