[WIP] Tracking guide

On our Brawl Survival server you are able to build "trackers". These are structures that you build inside the world that can be used to find the coordinates of a player, and (hopefully) the location of the wonderful base which that player has. I will try to make this guide as in-depth as possible, but this is a WIP so there may be missing information.

In the picture below we see a basic Emerald Tracker. The center of the tracker is a emerald block, the arms are iron blocks and the ends are gold blocks.


Basics
The basic idea of trackers is you build a structure, and you can use it to figure out players that are within a certain distance. There are arms on the tracker, and those arms determine how far in that direction you will be able to track. For example, if one of your arms have a tracking distance of 500 blocks, typing '/track all' will show you all players within 500 blocks of that tracking distance in that specific direction. Trackers do not need to have arms in all 4 directions. To be a valid tracker, all you need is an arm in at least 1 direction. Here is a image to sort of clarify this concept (thanks @Reptoid44):


- Tracker Types -
There are 3 types of trackers each type being slightly different. Every tracker has a specific scenario that it is useful in. To start, lets first clarify the parts of a tracker:
Temporary Tracker
Middle -> Obsidian Block
Arms -> Cobblestone Block
End -> Stone Block
Tracking Distance -> 25 + (25 * Arm Length)
Notes -> This tracker will delete itself after 1 use. This tracker is great for quickly building a tracker when you know you are near the location of a players base. I recommend you use a permanent tracker to track the rough area of someone, then use temporary trackers once you get near that player.

Diamond Tracker
Middle -> Diamond Block
Arms -> Obsidian Block
End -> Gold Block
Tracking Distance -> 25 + (25 * Arm Length)
Notes -> This tracker will take a long time to create and your arms will have to be quite long if you want to track long distances. The plus side of that though is if someone raids a diamond tracker, it will take them a very long time to mine all the obsidian arms.

Emerald Tracker
Middle -> Emerald Block
Arms -> Iron Block
End -> Gold Block
Tracking Distance -> 50 + (50 * Arm Length)
Notes -> I like to consider this tracker as the high risk - high reward tracker. It is really expensive to create a tracker of this type, but once you have one tracking people will be faster. The downside of this though is that if someone finds the location of your Emerald tracker, since the tracker's arms don't need to be as big and it isn't made out of obsidian, stealing the items from the tracker will be very easy.

- Techniques to using a tracker -
The basic technique to using a tracker is pretty simple, but also extremely time consuming. The more you practice, the better you will be at tracking others. To improve speed, I recommend you track players with at least 1 other person to help you. To use trackers effectively, what you want to do is first figure out who your target is. Stand on the center block of your tracker while it is set to maximum range and type '/track all'. This will show you all players that are in range. Pick one of these players and now it is time to start tracking. What you want to do is move the end block of your tracker around the arm of the tracker. Each time you move the block type '/track <player>'. The point of this is to try and pinpoint as accurate as you can the position of the player. Keep moving around that end point until you are at a situation where moving it one block closer to the center of the tracker will cause the player to not show up on the tracker anymore. Congratulations, you now know where that player is in the direction you were tracking accurate to 25 or 50 blocks. (Use the command feedback to figure out the distance you are tracking). Now you need to do this in 2 different directions, one to figure out where the player is on the X axis, and another to figure out where the player is on the Z axis. Once you have those distances from the tracker, do a little bit of math with minecraft coordinates and you will be able to pinpoint almost exactly where a player is. Gear up and head out to where you believe the person is. If you have trouble finding them use temp trackers to your advantage to look around the nearby area quickly. Remember that trackers ignore the Y-Coordinate so they can be as high or as low as Minecraft will allow them.

- How to avoid being tracked -
The best way to avoid being tracked is to never stay in the same location for too long. Don't go AFK while standing in your base and if possible don't store your items all in the same place on the map. Remember, tracking takes quite a bit of time, so the more you don't stay in one location the harder it will be for others to pinpoint your location.

- Conclusion -
If you have any suggestions or questions, please post a reply to this thread. Tracking is a complicated and often tricky process, but the more you practice and get the hang of it, the better you will learn and come up with your own tricks to tracking other players.
