How? without having to create the character so I spawn with those things on my first one
When you create the world, wait before spawning in. Click the pause button, and change the spawn items (view this thread if you need help figuring out how to do that). Then, you can spawn in as normal with your new spawn items.
If 1.8 is ever released (highly unlikely), this is the first thing on my wishlist. The whole process should be made easier!
I know you did, but that isn’t made obvious unless somebody actually tells you. Some players don’t seem to know about that.
