What is GlymeraHolo?

GlymeraHolo lets you place floating 3D text in your world by looking at any surface and typing a command. Each letter is rendered as a visible entity with its own texture. Text automatically faces towards you when placed, supports multiple lines, and can be scaled from tiny to huge. Choose from 10 vibrant colors.

Point, type, done.

How It Works

1. Look at a wall, floor, or any surface
2. Type /gholo set <color> <text> - text appears instantly, facing you
3. Multi-line - use | for line breaks (e.g. WELCOME|TO|SHOP)
4. Scale - add a size value between color and text (e.g. /gholo set Red 2.0 BIG)
5. Remove with /gholo remove <id>, /gholo remove all, or /gholo remove nearest
6. Realign with /gholo realign <id> to face your new position

Commands

*Non-OPs can create text if allowNonOps is enabled in config.

Permissions

• Players can only remove and realign their own texts
• OPs can remove any text (including other players'), and have no character/count limits
• /gholo remove nearest finds closest text (own for players, any for OPs)
• Text IDs are globally unique across all players
• Text creation is OP-only by default (configurable via allowNonOps)

Technical Details

• Each letter is an individual NPC entity with a custom quad model and colored texture
• Text persists across server restarts and chunk unload/reload
• Entity-based approach means zero world corruption risk - removing the plugin leaves no traces
• 490 pre-generated textures (49 characters x 10 colors) embedded in the JAR
• No external dependencies
