I can't seem to use models or understand controls

I am sort of new to Babylon.js . I longed to learn how to place models. I tried to place a bunny many times but it finds a error that didn’t exist in my other code that actually worked. Later on, I wanted to advance my knowledge of my way around Babylon.js by creating a game. I thought to make a Minecraft based game. I couldn’t make controls because I don’t understand mouse controls. I looked through some voxel engines and they have files scattered therefore it would be hard for me to copy and use in my code and tweak. I honestly am lost in Babylon.js and I don’t know why it doesn’t work. I’m just trying to make games so I can learn to make better games.

Have you got a look at the documentation to understand the rudiments of Babylon. It can really help you understand how it works.
