Forgive me if I do some things wrong with this, it is my first time posting on a forums board (I don't know how to create spoilers, and other things like that).
I recently got very bored and decided I wanted to try to create something hardcoded, because I have never made a client 100% hardcoded, my custom hacked client was actually nearly opposite. I decided that an Xray would be a perfect thing to test my ability, and it worked very well.
Features of this Xray:
Cape(Only shows to you)
Make the Xray blocks customizable
Make the cape customizable(Or maybe even have an uploading site so it's like a proper cape mod as well)
This was just exported straight through eclipse, so if you want to customize the cape or the xray blocks(and know how to) go right ahead.
That being said, please do not edit it and redistribute claiming it as yours
Other than that, I couldn't care less what you do with it.
