navigation-link-add	Add and configure a `NavMeshLink` on a GameObject. A NavMeshLink connects two points on (or off) the NavMesh — e.g. a jump-across or a doorway — so agents can traverse gaps the baked mesh does not cover. Points are local to the GameObject's transform.	generated-by mcp-plugin-dotnet

Navigation / Add NavMeshLink

Add a NavMeshLink to a GameObject. The link bridges startPoint and endPoint (in the GameObject's local space), letting agents cross between otherwise-disconnected NavMesh regions.

Inputs

• gameObjectRef — the GameObject to add the link to (required).
• startPoint — local-space start of the link (default 0,0,-2.5).
• endPoint — local-space end of the link (default 0,0,2.5).
• width — link width in meters (default 0).
• bidirectional — when true, the link is traversable both ways (default true).
• costModifier — cost override; negative means use the default cost (default -1).
• area — NavMesh area index of the link (default 2 = Jump).

Behavior

Adds (or reuses) a NavMeshLink, assigns the configured fields (which auto-rebuild the link), marks the scene dirty, and repaints. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool navigation-link-add --input '{
  "gameObjectRef": "string_value",
  "startPoint": "string_value",
  "endPoint": "string_value",
  "width": 0,
  "bidirectional": false,
  "costModifier": 0,
  "area": 0
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool navigation-link-add --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool navigation-link-add --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input

Name	Type	Required	Description
gameObjectRef	any	Yes	Reference to the GameObject to add the NavMeshLink to.
startPoint	any	No	Local-space start point of the link.
endPoint	any	No	Local-space end point of the link.
width	number	No	Link width in meters.
bidirectional	boolean	No	If true, the link is traversable in both directions.
costModifier	integer	No	Cost modifier for traversing the link; negative uses the default cost.
area	integer	No	NavMesh area index of the link (2 = Jump by default).
