def getSourceNodeName(self)

Undocumented function.

def getSourceTextureName(self)

Undocumented function.

def setSourceFileName(self, name)

Undocumented function.

Undocumented function.

addFromNode
void SpriteParticleRenderer::add_from_node(NodePath const &node_path, bool size_from_texels = (1), bool resize = (0));

Description : This will allow the renderer to randomly choose from more than one texture or sequence at particle birth.
If the source type is important, use this one.
model and node should lead to node_path like this: node_path = loader.loadModel(model).find(node)
If resize is true, or if there are no textures currently on the renderer, it will force the renderer to use the size information from this node from now on. (Default is false)

addTexture
void SpriteParticleRenderer::add_texture(Texture *tex, float texels_per_unit = (1), bool resize = (0));

Description : Adds texture to image pool, effectively creating a single frame animation that can be selected at particle birth. This should only be called after a previous call to set_texture().

setFromNode
void SpriteParticleRenderer::set_from_node(NodePath const &node_path, bool size_from_texels = (1));

Description : If the source type is important, use this one.
model and node should lead to node_path like this: node_path = loader.loadModel(model).find(node)
This will remove all previously add textures and resize the renderer to match the new geometry.
Description : Sets the properties on this renderer from the geometry referenced by the indicated NodePath. This should be a reference to a GeomNode or a SequenceNode; it extracts out the texture and UV range from the node.
This will remove all previously added textures and animations. It will also resize the renderer to match this new geometry.
If node_path refers to a GeomNode(or has one beneath it) the texture, its size, and UV data will be extracted from that.
If node_path references a SequenceNode(or has one beneath it) with multiple GeomNodes beneath it, the size data will correspond only to the first GeomNode found with a valid texture, while the texture and UV information will be stored for each individual node.
If size_from_texels is true, the particle size is based on the number of texels in the source image; otherwise, it is based on the size of the first polygon found in the node.
model and node are the two items used to construct node_path. If the source type is important, use set_from_node(NodePath,string,string,bool) instead.

void SpriteParticleRenderer::set_initial_x_scale(float initial_x_scale);

Undocumented function.

setLlUv
void SpriteParticleRenderer::set_ll_uv(LPoint2f const &ll_uv);

Description : Sets the UV coordinate of the lower-left corner of all the sprites generated by this renderer. Normally this is (0, 0), but it might be set to something else to use only a portion of the texture.

setNonanimatedTheta
void SpriteParticleRenderer::set_nonanimated_theta(float theta);

Undocumented function.

setSize
void SpriteParticleRenderer::set_size(float width, float height);

Description : Sets the size of each particle in world units.

Description : Sets the renderer up to render the entire texture image. The scale of each particle is based on the size of the texture in each dimension, modified by texels_per_unit.
Used to set the size of the particles. Will clear all previously loaded textures and animations.

setUrUv
void SpriteParticleRenderer::set_ur_uv(LPoint2f const &ur_uv);

Description : Sets the UV coordinate of the upper-right corner of all the sprites generated by this renderer. Normally this is (1, 1), but it might be set to something else to use only a portion of the texture.

Undocumented function.

setYScaleFlag
void SpriteParticleRenderer::set_y_scale_flag(bool animate_y_ratio);

Class : Published
Description : Query the geomnode pointer

getUserAlpha
float BaseParticleRenderer::get_user_alpha(void) const;

Description : gets alpha for "user" alpha mode

output
virtual void BaseParticleRenderer::output(ostream &out) const;

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

setAlphaMode
void BaseParticleRenderer::set_alpha_mode(BaseParticleRenderer::ParticleRendererAlphaMode am);

Undocumented function.

setColorBlendMode
void BaseParticleRenderer::set_color_blend_mode(ColorBlendAttrib::Mode bm, ColorBlendAttrib::Operand oa = (O_zero), ColorBlendAttrib::Operand ob = (O_zero));

Description : sets the ColorBlendAttrib on the _render_node

setIgnoreScale
void BaseParticleRenderer::set_ignore_scale(bool ignore_scale);

Description : 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
void BaseParticleRenderer::set_user_alpha(float ua);

Description : sets alpha for "user" alpha mode

write
virtual void BaseParticleRenderer::write(ostream &out, int indent = (0)) const;

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

getClassType
static TypeHandle ReferenceCount::get_class_type(void);

Undocumented function.

getRefCount
int ReferenceCount::get_ref_count(void) const;

Description: Returns the current reference count.

ref
int ReferenceCount::ref(void) const;

Description: Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is the new reference count.

testRefCountIntegrity
bool ReferenceCount::test_ref_count_integrity(void) const;

Description: Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise.

unref
int ReferenceCount::unref(void) const;

Description: Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().
