Hi,
A long time ago I was playing TerraFirmaCraft (TFC) which was also my first experience with Minecraft. I found that 1) I didn't have a map and 2) mixing alloys was a pain. That's why I setup this site for myself and my friend.
I never intended for this to be public so it's kinda rough and has no comment, feedback or even facebook integration :) However, after watching some of Modii101 and HeatherReneeB's episodes of TerraFirmaPunk I decided I might start playing it and thought others might find my pages useful.
The 3 input fields are: name, x and z; enter all 3 and click Add to store a new coordinate. The name Home will mark this as your home location and place it at the top of the list.
Use the coordinaes to calculate a route which will tell you how many blocks you need to travel in which direction.
The coordinates are stored in your browser's storage and will be remembered next time you visit the page.
This will help you mix metals in the right ratio to make the alloy you need. It will tell you if you have too much or too little of one of the metals.
If you have all metals required, it will show you how many units of alloy it will make (based on the type of nugget). Each ingot or tool uses 100 units (or a multiple, I don't remember) and it will show you how many remainder you'll have that you will no be able to extract from the jar.
