|
|
*
|
|
* Note that as a video editor, the node graph has to work across time. Depending on the purpose of your node, it may
|
|
* output different values depending on the time, and even if not, it will likely be receiving different input
|
|
* depending on the time. Most of the difficult work here is handled by NodeInput::get_value() which you should pass
|
|
* the `time` parameter to. It will return its value (at that time, if it's keyframed), or pass the time to a
|
|
* corresponding output if it's connected to one. If your node doesn't directly deal with time, the default behavior
|
|
* of the NodeParam objects will handle everything related to it automatically.
