js to c# conversion problem (im a noob sorry)

Hi all, this is my first time on these forums so forgive me if im being stupid or anything.
Last night I started to try andconvert a youtube tut trying to explain and show one how to code a minecraft scenario wherby block can be instantiated by a left mouseclick and a range of block types could be coded and changed via right mousecllick.
Me being me, had to NOT just follow his javascript example but try and change it to a C# implementation.
This is where im having a bit of bother. Below is the code , and i know its something really silly like i am missing a simple typecast or i havent set up my raycast correctly or i havent filled enough arguements into my new Transform instantiaition.
ANyway, hoope this is soo obvious a mistake to make for a noob, I dont get flamed too much form not knowing already.
Thanks for reading :slight_smile:

I removed my previous answer to unclutter this page a bit. I’ve converted things to work in the way I’m thinking you wanted them to. Keep your original project. Start a new project in Unity, then import this package I have uploaded. You should see your voxelTest scene in the assets folder. I have removed some unnecessary things and added a couple optional things you may or may not wish to use. Tweak this however you wish. If you need more help, let me know, and explain what you’re wanting to do with certain things because some of the commented out code was a bit puzzling lol. Here is C47 Conversion.unitypackage
