Pointer Lock Mouse Test
An advanced diagnostic arena utilizing the Pointer Lock API to capture continuous, unconstrained relative coordinate deltas without screen edge collisions.
Click Inside to Lock Pointer
Allows continuous movement without edge boundaries. Press ESC to unlock.
2. How the Pointer Lock API Works
Normal web applications track the cursor via absolute screen pixels (clientX, clientY). When your cursor reaches the edge of your screen, absolute position stops changing. Pointer Lock hides the cursor, locks it to a fixed position, and delivers pure infinite relative deltas (Δx, Δy).
3. Why 3D Games Require Pointer Lock
First-person shooters (CS2, Valorant, Apex) require infinite continuous 360-degree rotation. WebGL 3D games and web-based aim trainers use this exact API to ensure that moving your mouse 30 cm across your mousepad continuously rotates your 3D perspective without interruption.
