Template:Schematic

Documentation

This template uses Module:Schematic, a script written in the Lua programming language. Please see wp:Lua and mw:Extension:Scribunto to learn more about Lua.

Schematic of 3-clock

This template displays a grid of block sprites to symbolically represent a Minecraft structure (primarily redstone circuits and mechanisms).

Usage

Schematic uses unnamed parameters to define the sprites used in the schematic, and named parameters to modify the schematic's default appearance:

{{Schematic
|caption=<caption>
|captionstyle=<captionstyle>
|clear=<clear>
|float=<float>
|size=<size>
|style=<style>
|tablestyle=<tablestyle>
|<param1>|<param2>|…
}}

caption: The optional caption parameter may be added to create a caption under the schematic. Adding a caption automatically also creates a box surrounding the schematic and caption, and floats the box to page right. An icon link to the schematic help page is automatically added to all captions.

captionstyle: The optional captionstyle parameter may be added to change the appearance of the caption area and contents. Its value should be a css declaration or declaration group with no surrounding braces or quotes (e.g., captionstyle=color: red; text-align: center;). This parameter has no effect if caption and float are not specified.

clear: The optional clear parameter may be added to force the schematic to drop below other floated elements. Its value may be left (to drop below only left-floated elements), right (to drop below only right-floated elements), both (to drop below all floated elements), or none (the default).

float: The optional float parameter may be added to change the side to which the schematic floats if a caption is added. The only value recognized is left -- anything else defaults back to floating to the right.

A schematic with no caption or float parameters acts like any other wiki table, ending the previous line and pushing subsequent text to a new line.

size: The optional size parameter may be added to specify the width and height of the sprite cells in pixels. Its value should be a simple number with no units added (e.g., size=16). If omitted, size defaults to 32.

style: The optional style parameter may be added to change the appearance of the schematic's surrounding box. Its value should be a css declaration or declaration group with no surrounding braces or quotes (e.g., style=background-color: yellow;). This parameter has no effect if caption and float are not specified.

tablestyle: The optional tablestyle parameter may be added to change the appearance of the schematic table. Its value should be a css declaration or declaration group with no surrounding braces or quotes (e.g., tablestyle=background-color: green;).

param: The param parameters specify the content of the schematic. When multiple params are defined, the resulting sprites or text are displayed in individual table cells, one after the other, unless a plus sign is used to stack them in the same cell.

Sprite sheet for Schematic

A sprite identifier (see list below) displays a sprite from the image on the right.
A dash (-) starts a new row.
Anything else is simply displayed as center-aligned text within the cell's bounding box (empty parameters or whitespace parameters are displayed as empty cells).
- Overflow text is not displayed, so this is primarily intended to be used to display one or two characters in a schematic (such as input and output locations, feature markers to be referenced in text, numbers representing light levels or distance, etc.).
- HTML character entity references may be needed for some characters, such as | for the pipe character: |, = for an equals sign, + for a plus sign (to be displayed as text rather than stacking the next param), or - for a dash (to be displayed as text rather than starting a new row). ̅ after a letter will provide a "combining overline" over the letter (used to indicate an inverse signal such as Q̅).

Multiple sprites and text may be stacked in the same cell by separating them with a plus sign (+), lower layers before upper layers.

Considerations

Overuse of the schematic template can create a high server load, resulting in long page generation times or even a time-out failure. This server load is proportional to the number of schematic cells on a page (for example, one 100-cell schematic and ten 10-cell schematics produce roughly the same server load). When the number of schematic cells on a page start to exceed a few hundred (or fewer, with other high-load templates), consider using {{LoadBox}} or {{LoadPage}} to offload some or all schematics into user-requested subpages.

List of identifiers

A sprite identifier is a string of characters that specify which sprite to display.

Some conventions to remember:

Directions are indicated by n (north), s (south), e (east), w (west), u (up), and d (down). Directions are relative to the schematic, not the Minecraft world.
$ indicates a side view sprite.
! indicates a powered/activated component.
