Task

Simulate mouse input via Input System in Unity PlayMode, or dry-run a Game View coordinate against 3D physics without injecting input.

Workflow

1. When checking what a screenshot coordinate would hit in 3D physics before clicking, run uloop simulate-mouse-input --dry-run --x <x> --y <y> first (EditMode is fine; no Input System required)
2. Ensure Unity is in PlayMode (use uloop control-play-mode --action Play if not) before injecting real mouse input
3. For Click/LongPress: determine the target Game View input position from annotated SimX/SimY, raycast-grid InputX/InputY, or raw image pixels converted with ScreenshotToInputFormula
4. Execute the needed uloop simulate-mouse-input commands
5. Inspect the result with the lightest useful evidence: runtime state, logs, or a screenshot
6. When this input verifies a state transition, use Pause Point inspection from the section below as the standard frame proof
7. Report what happened and which evidence was used

Two rules while verifying:

• Do not touch the physical mouse or keyboard, and keep the OS pointer off the Unity window — real device input mixes into the same Mouse.current state this tool injects.
• Read the starting values you will assert against immediately before firing the input; a value measured earlier in the session may have changed.
