VR Expansion Plugin

Hi,I’m new for leaning it, I just want to realize the function of grabbing objects. I read your example template. Sorry, I’m just a novice. In my opinion, there are many irrelevant contents that make it difficult for me to understand part of the code. I also read the function introduction in your plug-in, but it doesn’t give an example, which makes it difficult for me to understand. I want to ask you what advice you have for achieving just grabbing objects. Thank you.
