This will allow the renderer to randomly choose from more than one texture or sequence at particle birth.
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 SpriteParticleRenderer::set_from_node | ( | const NodePath & | node_path, |
bool | size_from_texels = false |
||
) |
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.
