Member Function Documentation

ParticleRendererAlphaMode getAlphaMode ( ) [inherited]
VBase4 const getHeadColor ( )
bool getIgnoreScale ( ) [inherited]

Returns the "ignore scale" flag.

See set_ignore_scale().

float getLineScaleFactor ( )

accessor

GeomNode getRenderNode ( ) [inherited]

Query the geomnode pointer.

NodePath getRenderNodePath ( ) [inherited]

Query the geomnode pointer.

VBase4 const getTailColor ( )
float getUserAlpha ( ) [inherited]

gets alpha for "user" alpha mode

output ( ostream  out) [inherited]

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

setAlphaMode ( ParticleRendererAlphaMode  am) [inherited]
setColorBlendMode ( Mode  bm) [inherited]

sets the ColorBlendAttrib on the _render_node

setColorBlendMode ( Mode  bm,
Operand  oa,
Operand  ob 
) [inherited]

sets the ColorBlendAttrib on the _render_node

setColorBlendMode ( Mode  bm,
Operand  oa 
) [inherited]

sets the ColorBlendAttrib on the _render_node

setHeadColor ( VBase4 const  c)
setIgnoreScale ( bool  ignore_scale) [inherited]

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.

setLineScaleFactor ( float  sf)

accessor

setTailColor ( VBase4 const  c)
setUserAlpha ( float  ua) [inherited]

sets alpha for "user" alpha mode

write ( ostream  out) [inherited]

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

write ( ostream  out,
int  indent 
) [inherited]

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