npx --yes uloop-cli@2.2.0 raycast

Check what a top-left Game View coordinate hits in 3D physics.

Usage

npx --yes uloop-cli@2.2.0 raycast --x <x> --y <y> [--layer-mask <mask>] [--max-distance <distance>]

Parameters

Parameter	Type	Default	Description
--x	number	0	Target X position in Game View pixels (origin: top-left). Use AnnotatedElements[].SimX, RaycastGridPoints[].InputX, or raw image pixels converted with ScreenshotToInputFormula.
--y	number	0	Target Y position in Game View pixels (origin: top-left). Use AnnotatedElements[].SimY, RaycastGridPoints[].InputY, or raw image pixels converted with ScreenshotToInputFormula.
--layer-mask	number	Unity default raycast layers	Physics layer mask used by the raycast.
--max-distance	number	1000	Maximum raycast distance in world units.

Coordinate System

• --x / --y use the same top-left Game View input coordinates as simulate-mouse-input.
• Raw image pixels from npx --yes uloop-cli@2.2.0 screenshot --capture-mode rendering must be converted with ScreenshotToInputFormula.
• AnnotatedElements[].SimX/SimY and RaycastGridPoints[].InputX/InputY can be passed directly to this tool.
• Do not flip Y in the caller. The tool converts internally:

unity_x = input_x
unity_y = gameViewHeight - input_y

Examples

# Check what is under a screenshot coordinate
npx --yes uloop-cli@2.2.0 raycast --x 960 --y 540

# Check only specific layers
npx --yes uloop-cli@2.2.0 raycast --x 960 --y 540 --layer-mask 1

Output

Returns JSON with:

• Success: Whether the command completed
• Message: Status message
• Hit: Whether physics hit anything
• HitGameObjectName / HitGameObjectPath: Hit object identity when Hit is true
• HitLayer / HitLayerName: Hit object layer when Hit is true
• Distance, HitPointX/Y/Z, HitNormalX/Y/Z: Hit details when Hit is true
• InputCoordinateSystem, UnityCoordinateSystem, GameViewWidth/Height, InputPositionX/Y, InjectedUnityPositionX/Y, CoordinateConversionFormula: Coordinate conversion details

Notes

• Requires an active Camera.main.
• Uses Unity Physics raycasts, not UI EventSystem raycasts.
