Client-side Xaero's World Map integration for Shrinkin Zone. Displays the live zone border as a dashed blue outline and the active phase target center as a temporary surface marker.

Purpose

Shrinkin Zone - Xaero's World Map add-on makes the current Shrinkin Zone state visible directly on Xaero's World Map. It is designed for players who need to plan movement around a large battle area without relying only on the in-world boundary wall.

The add-on does not modify zone mechanics, phase timing, target selection, damage, or server state. It reads the synchronized Shrinkin Zone client state and renders an overlay on the full-screen world map.

How it works

1. Shrinkin Zone synchronizes the current and target zone bounds to the client.
2. The add-on registers a custom map-element renderer with Xaero's World Map.
3. The current interpolated zone borders are converted into dashed blue map elements.
4. While the zone is shrinking, the outline moves together with the live zone borders.
5. A temporary marker is placed at the center of the target area for the active phase.
6. The marker's Y coordinate is resolved from available surface data when possible, with a temporary fallback until the surface height can be determined.
7. When the phase target changes, the previous center marker is replaced automatically by the marker for the new target.

Dependencies

All dependencies below are required on the client.

The add-on itself is client-side only and does not need to be installed on a dedicated server.

Configuration

The add-on has no separate configuration file in version 1.0.0.

Its overlay appears automatically when:

• Shrinkin Zone is active;
• the player is viewing the matching dimension;
• Xaero's World Map is available on the client.

Compatibility

• Minecraft 1.21.1
• NeoForge 21.1.243 or newer within the 1.21.1 branch
• Shrinkin Zone 1.0.0
• Xaero's World Map 1.45.0
• Client-side installation only

The add-on uses Xaero's map-element rendering system rather than replacing or patching normal map tiles. Existing explored map data remains unchanged.
