# Basic Usage of Signs | MishangUC

This mod adds sign blocks with various textures.

# I. Sign Categories

Signs in the MishangUC mod are mainly divided into the following three types:

# 1. Hanging Signs

This type of sign should be hung below a block, and text can be entered on both sides. If a solid block or a sign pole block is connected above, a sign pole will be displayed.
The text on the sign is bound to its placement direction; direct rotation is not currently supported. If you need to place a block with NBT data, ensure the placement direction matches the direction it was obtained in; otherwise, text will not appear on the corresponding side. For example, if you obtain a sign facing north/south and place it facing east/west, the original text on the north/south sides will not display.

# 2. Wall Signs

This type of sign can be placed on any surface of a block (side, top, bottom), with only one writable face.
Wall signs have two special variants: Invisible Sign and Invisible Glow Sign. The models of these two sign types are invisible, with only text visible. When a player holds either type, placed invisible signs will show an outline for easy identification.

# 3. Standing Signs

Placed on the ground or floating, supporting the original 16 directions. Like hanging signs, both sides can have text input.
A pole will appear when a block is placed underneath. While empty-handed, hold Shift and click the sign to manually toggle the pole visibility.

# II. Basic Text Editing

When a player right-clicks a sign, the editing interface opens (click the corresponding side for hanging/standing signs). The sign supports multi-line text, with each line independently configurable for the following properties:

# 1. Basic Styles

Bold, italic, underline, strikethrough, random text, etc.

# 2. Text Size

Default value: 6. Full-size signs (including both invisible variants) have a default of 8.

# 3. Offset (X/Y/Z)

Adjusts text offset along the three axes.

⚠️ Adjust the Z-axis carefully, as it may cause text to float off the plane or clip behind the sign and become invisible.

# 4. Scale (X/Y)

Stacks with text size. Setting scale to 0 will hide the text.

There is no Z-axis scaling, as it serves no purpose on a 2D plane.

# 5. Rotation

Supports rotation around the X, Y, and Z axes.

# 6. Alignment

Supports horizontal and vertical alignment.

# 7. Color & Outline

Text Color: Built-in 16 colors / custom color.
Outline Color: Disabled, auto-match text color (vanilla glow behavior), built-in color, glowing variant of built-in color / custom color.

# 8. Shadow

⚠️ Not recommended. Enabling shadows for multi-directional text may cause rendering order issues.

# 9. Absolute Mode

When enabled, this line will be ignored during the "Rearrange" function.

# III. Advanced Typography & Editing Features

# 1. Button & Value Adjustment

# Basic Controls

Left-click: Adjust
Right-click / Shift+Left-click: Reverse adjust
Middle mouse wheel / Alt+Shift+Left-click: Reset to default

Mouse wheel scrolling can also be used directly.

# Speed Multipliers

Hold Ctrl for ×8 speed
Hold Alt for 1/8 speed

# Custom Value Input

Click "Set Custom Value" then the target button, or press Tab to focus and Ctrl+E to enter a value.

Color support: color name (e.g., red) or hex code (#rgb, #rgba, #rrggbb, #rrggbbaa). For outline, enter none (disabled) or auto (automatic).

# 2. Text Layout & Multi-Selection

# Auto Layout

Click "Adjust Position" to arrange lines from top to bottom based on text size (with 1/8 line spacing, excluding lines with Absolute Mode enabled). Different vertical alignments operate independently.

# Multi-Selection

Hold Ctrl or Shift to select multiple lines for batch settings or input. Button increments apply relative changes; custom values or defaults apply uniformly to all selected lines.

# Cross-Block Overflow

Text remains visible beyond the sign area. To center text between two single-block signs, type on the left sign, set center alignment, and offset right by 8 units.

# 3. Back Side Copy & Flip

# Copy from Back Side

Hanging/standing signs can directly copy text from the opposite side. During copying, X offset, horizontal alignment, and in-text arrows (e.g., →) are automatically reversed, ideal for double-sided signs.

# Flip

Select a single line and click "Flip" to reverse its X offset, alignment, and arrows. Hold Ctrl and click "Flip" to apply to all lines.

# 4. Rendering Notes

# Z-Fighting

Easily occurs with translucent text + bold / translucent outline.

# Opacity Behavior

When outline color is set to "auto", its opacity follows the text. If a specific color is chosen, it is unaffected by text opacity.

# Transparency Occlusion

Translucent text may prevent translucent content behind it (stained glass, water, clouds) from rendering.

# IV. Keyboard Shortcuts (1.19.4+)

Tab switches between text area and button area; arrow keys navigate between buttons/text lines.

Example: Press Tab to select "Bold", press Enter to toggle, press Right Arrow to "Italic" and Enter to toggle.

# 2. Quick Styles

Shortcut	Action
`Ctrl + I`	Italic
`Ctrl + S`	Strikethrough
`Ctrl + U`	Underline
`Ctrl + O`	Obfuscated

Note: Ctrl+B conflicts with narrator and is not used for bold.

# 3. Line Operations

Action	Shortcut
New line	`Ctrl+Shift+=` or `Ctrl+Numpad+`
Delete line	`Ctrl+-` or `Ctrl+Numpad-`
Move line	`Ctrl+Shift+Up/Down Arrow`

# V. Special Format Commands

Enter the following special commands in text lines to insert custom content:

# 1. Data Components & Graphics

-json <code>: Custom JSON text (lenient mode, quotes for keys/values optional).
- Example: -json {text:Some Text, color:red, bold:true}
-nbt <component>: Use NBT for text (1.21.5+ only).
-rect <width> <height>: Draws a rectangle of specified size (affected by text size and scale).
-texture <path>: Displays a texture (resource pack dependent; online images not supported). Using -nbt {sprite: 'block/lava_still'} is recommended for stability and animated texture support.

# 2. Built-in Patterns (-pattern)

Using built-in pattern names avoids alignment/size inconsistencies from fonts or Unicode.

# Basic Arrows & Directions

(empty)	`-pattern empty`
←	`-pattern arrow-left` or `-pattern al`

⚠️ Note: Custom styles are not supported for patterns. For complex styling, use the -texture format or vanilla sprite components (example: -nbt {sprite: xxx}).

# VI. Item Interaction Features

# 1. Waxing & Dewaxing (Honeycomb)

Using a honeycomb on a sign applies wax, which locks editing and glow state.

Dewaxing with honeycomb is only available in Creative mode (not Survival).

# 2. Glow Effect (Glow Ink Sac / Ink Sac)

Glow Ink Sac: Makes text glow (brightest in darkness, no effect on outline or block light level).
Ink Sac: Removes text glow.

For hanging and standing signs, waxing and glowing are applied independently to each side. In non-Creative modes, each successful wax/glow action consumes the corresponding item.
