First question:
How do I find my coordinates in the world?
I use ender's client. Have a key command that shows my coordinates?
Second question:
I wanted to make an edit in the texture of the game, I downloaded a texture pack that I just liked the texture, but I just did not know how to put it, I looked in the folder where I downloaded that texture, I found files. Res
I downloaded a Resource Editor to open the files to see what was what I wanted, but appeared several letters which I did not understand, I know it's a java programming language for the file, but the question is:
How do I make a texture for the game?
And where I think and how I open the files of the current texture of the game?
Respond quickly please, I'm a little impatient
