Construction tools for large building projects

What’s in here

This will end up being a collection of tools, to make it easier to build large buildings or other structures. The tools are intended to be ephemeral tools, like the scaffolding block: you use them for as long as you need them, and then you get rid of them.

The first tool is a _datum_.

Datum

In real life, architects and builders always start with a reference point, a zero-zero point in the project. Everything else is measured from that starting point. Sometimes this is called a _benchmark_, and sometimes it’s called a _datum_. I’m going to use the term _datum_ because it’s fewer letters.

During development, I discovered that the datum also works as a “home” marker when you’re exploring a world.

How to use it

In version 0.0.1, you must have commands enabled to use the datum. A future version will eliminate the need for commands.

Create a datum

The command /datum will place a datum where the player is standing.

The command /datum xxx yyy zzz will place a datum at the coordinates (xxx, yyy, zzz). For example, /datum 240 80 -35 will place a datum at (240, 80, -35).

The datum block cannot be destroyed using left click or right click. Players can walk through it. It can hang in the air. There’s really no way to interact with the datum block. It only exists to show you where the datum point is.

When a datum point exists, an overlay in the upper right shows you the following items:

• The datum x, y, and z coordinates.
• The player’s distance from the datum, in directions x, y, and z. The distances also show north, south, east, west, up, and down.
• The player’s horizontal distance from the datum. (You know, a circular radius in x and z.)
• The player’s 3D distance from the datum. This is a spherical radius.
• The compass heading from the datum to the player. _Note from the author: I don’t like this. I think it’s clumsy and almost useless. I will replace it with something better._

Remove the datum

The command /datum remove removes the datum block and erases the overlay.

Move the datum

You don’t have to remove the datum in order to place a new one somewhere else. Simply using the command \datum or \datum xxx yyy zzz will remove the existing datum and create a new one in the new location, essentially moving the datum.

Use the remote

In version 0.0.2, a datum remote is added that allows players to use the datum in survival mode – that is, without having to enable commands or cheats.

The datum remote is crafted from two mithril ingots and a magichite crystal. Mithril ore is a brilliant white ore, so brilliant that it glows in the dark. Magichite is a multicolored crystal. The remote can be treated just like any other item.

With the remote in the right hand, right-click to see a gui with three buttons:

• Create datum
• Move datum
• Remove datum

These buttons work identical to the /datum and /datum remove commands. The /datum xxx yyy zzz command is not accessible (yet) from the remote.

What about having multiple datums?

I thought of adding support for multiple datums, but that’s more complicated than what I need. I don’t think that the additional functionality of having multiple datums is worth the additional effort required to support multiple datums.

One datum at a time.

Yeah, but what about multiple players with datums?

So far, this is a one-player project. I would need to add an “owner” attribute to the datum block, so that each player’s datum would be unique, and one player couldn’t mess with another player’s datum. For now, just one datum at a time.

Datum behavior in a multiplayer environment, for version 0.0.1 is unknown, unpredictable, and unsupported. For now, it’s one datum, one player.

Other tools

In version 0.0.1, the datum is the only tool. I had to start somewhere. Other tools will follow. Suggestions are welcome.

Version 0.0.2 is a collaboration with my grandson to all the datum to be used in survival mode.

Why did you bother doing this?

I wanted to build a giant sphere. A freakin’ huge, spherical, Death Star. I wrote a little Python program that would calculate integer (x, y) coordinates for a sphere of a given radius, and I tried to place the blocks according to the printed list of (x, y) coordinates, slice by slice. I thought, _”Man, there has to be a better way to do this.”_ The datum is the better way — it makes it so much easier.
