Nodes how to make and use them?

Thanks for the help but how do asigh things as nodes and what exactly do you use nodes for? I’m new to making anything other than static models and while I’ve been working through a lot of tutorials to figure out how to do thing I havent found out much info on nodes besides that they’re markers.

Thanks for any help in advance you guys have been very helpfull.

Did you ever heard something about graphs or graph theory?
A node is just a point in a graph/tree.
If you load a model

model= loader.loadModel( 'model.egg' )

model is a NodePath to display it you call


render is a node. every thing in the render tree will be rendered.
reparentTo tells the node that render is his parent its now below the render node and render knows that model is a child of it.

Hope you understand it
