✨ EdgeRender — Block Outline Highlighting Library

Glowing edge outlines for selected blocks — powered by RPC

EdgeRender is a library addon for Minecraft Bedrock that renders glowing wireframe outlines around selected blocks. Designed for other addons to use via RPC and Service Discovery, it provides per-player block highlighting with smart edge culling — inner edges between adjacent blocks are hidden automatically.

This addon does nothing by itself. It must be installed alongside other addons that support it (such as OrePop or ChopPop) to provide visual feedback.

Features

Per-Player Outlines: Each player sees only their own block selections
Smart Edge Culling: Inner edges between adjacent selected blocks are hidden automatically — only outer edges glow
Glow-Through-Walls: Edges remain visible behind blocks
Lighting Independent: Emissive texture for consistent brightness in any lighting
Zero-Collision: Outlines don't block movement or interaction
RPC-Driven: Other addons communicate with EdgeRender via @mcbe-mods/rpc
Service Discovery: Automatically discoverable via @mcbe-mods/discover

Installation

Download the .mcaddon file
Open the file with Minecraft Bedrock Edition to import it
Create or edit a world, go to Settings → Behavior Packs and Resource Packs
Apply EdgeRender to both Behavior Packs and Resource Packs
Ensure at least one addon that supports EdgeRender (such as OrePop or ChopPop) is also installed
Enter the world — outlines will appear automatically when supported addons detect blocks

Compatibility

Minecraft 1.21.80 and above
Uses stable @minecraft/server@1.18.0
Requires both Behavior Pack and Resource Pack to be applied
Achievements supported

For Addon Developers

Addons can communicate with EdgeRender using @mcbe-mods/rpc and @mcbe-mods/discover:

const rpc = new RPC({ namespace: 'edge_render' })

// Show outlines
await rpc.invoke('create', {
  playerIds: [player.id],
  locations: [{ x: 10, y: 64, z: 10 }]
})

// Remove outlines
await rpc.invoke('remove', { playerIds: [player.id] })

See the GitHub repository for detailed developer documentation.
