void add_from_node(NodePath const &node_path, bool size_from_texels = false, bool resize = false)

void add_from_node(NodePath const &node_path, std::string const &model, std::string const &node, bool size_from_texels = false, bool resize = false)

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)

void add_texture(Texture *tex, PN_stdfloat texels_per_unit = 1.0, bool resize = false)

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().

void set_from_node(NodePath const &node_path, bool size_from_texels = false)

void set_from_node(NodePath const &node_path, std::string const &model, std::string const &node, bool size_from_texels = false)

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.

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 set_initial_x_scale(PN_stdfloat initial_x_scale)

void set_initial_y_scale(PN_stdfloat initial_y_scale)

void set_ll_uv(LTexCoord const &ll_uv)

void set_ll_uv(LTexCoord const &ll_uv, int const anim, int const frame)

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.

void set_nonanimated_theta(PN_stdfloat theta)

void set_size(PN_stdfloat width, PN_stdfloat height)

Sets the size of each particle in world units.

void set_texture(Texture *tex, PN_stdfloat texels_per_unit = 1.0)

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.

void set_ur_uv(LTexCoord const &ur_uv)

void set_ur_uv(LTexCoord const &ur_uv, int const anim, int const frame)

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.
