Hi @m_adam ,

Thanks for your reply, it worked well.

But I still have some doubts about the usage of Node Path, such as how to calculate the port through NodePath instead of concatenating strings (which can easily lead to misoperation).

There are few examples and answers for NodePath on the forum, and it seems that people rarely use it. Do you have any insights on this, or in other words, what usage scenarios do you think NodePath is more suitable for.

Cheers~
