cinemachine-set-aim	Add or replace the rotation-control (Aim) component of a `CinemachineCamera`, chosen by `AimType` (RotationComposer, HardLookAt, PanTilt, or None). Applies common params (screen X/Y, damping) to RotationComposer where applicable.	generated-by mcp-plugin-dotnet

Cinemachine / Set Aim

Add or replace the Aim (rotation-control) component of a CinemachineCamera. Any existing Aim component is removed first, then the chosen one is added — so this is destructive to the previous Aim component.

Inputs

• gameObjectRef — the GameObject hosting the CinemachineCamera (required).
• aimType — AimType enum: RotationComposer, HardLookAt, PanTilt, or None (removes the Aim component).
• screenX, screenY — optional normalized on-screen target position for RotationComposer (Composition.ScreenPosition). Typically in the range -0.5..0.5 (0,0 = center).
• damping — optional uniform damping value (applies to RotationComposer.Damping).

Behavior

Removes every existing CinemachineRotationComposer, CinemachineHardLookAt, and CinemachinePanTilt on the GameObject, then adds the requested one and applies the optional params. Marks the scene dirty and repaints. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool cinemachine-set-aim --input '{
  "gameObjectRef": "string_value",
  "aimType": "string_value",
  "screenX": "string_value",
  "screenY": "string_value",
  "damping": "string_value"
}'

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

unity-mcp-cli run-tool cinemachine-set-aim --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool cinemachine-set-aim --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 containing the CinemachineCamera component.
aimType	string	Yes	Which rotation-control (Aim) component to use.
screenX	any	No	Normalized on-screen X target position for RotationComposer (Composition.ScreenPosition.x).
screenY	any	No	Normalized on-screen Y target position for RotationComposer (Composition.ScreenPosition.y).
damping	any	No	Uniform damping value applied where the component supports damping (RotationComposer).
