Thermals

Introduction

Thermals is a Bukkit plugin for logging redstone events located in a world. The user can then request the generation of heat maps for an area, showing the redstone activity. Higher activity means hotter regions, lower, cooler. No activity is colorless, and the background is visible.

Installation

Drop the Thermals.jar into your plugins folder. Start up the server to generate the plugins/Thermals/ folder and the config.yml configuration in it.

Configuration

This will be explained section by section.

Database connection information

database:
    type: MySQL
    host: localhost
    port: '3306'
    name: minecraft
    user: root
    password: password

Change this information to match your database information.
Here are the supported types:

  • MySQL
  • More to come!

Some databse types might not require all of the information under the database section.
Here is the list of the necessary information for each type:

  • MySQL: all of the information

Logger

logger:
    world: world
    delay: 30000
    run-threshold: -1
    suppress-info: false

These are the settings for the logger, which records the information to the database. It will run periodically, processing all or a limited number of records, called "heats".

The first setting is the world. The logger will log all of the redstone change events in the specified world only. An invalid world will lead to a partially loaded and not functional plugin.

You can change the delay between each run. It is milliseconds. The default is 30 seconds.

The run threshold is the maximum of heats to process during each run. -1 represents no maximum. It is the recommended default.

You can suppress the logging to the console of the information for each run by changing the suppress-info value to true.

The generator is a process responsible for generating the heat map images from the information stored in the database.

The heat generator will ignore any values bellow the minimum bound. Any above the maximum will be treated as being equal to this value. The minimum bound represents no heat, and the maximum, maximum heat

The heat gradient is used to map integer values to colors. It is ordered from coolest to hotest. Colors are expressed in the standard RGB way, with each color component ranging from 0 to 255. You can add as many colors as you want to the list. The default gradient is the thermographic one, with, from coolest to hotest: black, dark purple, redish pink, orange, yellow and white.

The heat maps have a configurable background color, with optional grids and coordinates. The background color is, by default, a dark grey. A green grid, with lines spaced 16 blocks apart is also drawn. Coordinates too are added every 3 grid lines, at intersections. These points of intersection will be marked in red. The font used is "Myriad Pro", size 10, in black.

Heat maps are overlayed on the background, and might mask some of the grid and coordinates.

Formatting key

This is the meaning of the formatting used in the documentation bellow.

[(type) value]

  • User defined arguments are between brackets.
  • The types for the arguments are between paranthesis.
  • Floating words are constants, and shouldn't be altered.

Argument Types

Integer

Represents an integer (whole) number with a value range of about -2 to 2 billion.
Decimal places are not accepted.

Location

Represents a 2D location in a world.

Format:

[(integer) x],[(integer) z] OR here OR there

here represents the player's current location (x and z).
there represents the player's target location (x and z of the block being looked at, up to 500 blocks away).
here and there can only be used in game.

Example:

-32,76

There is no space after the coma separator!

String

A simple chain of alphanumeric characters without any whitespace.

Example:

string_example1
