Vjoy Mouse Steering ~upd~ Jun 2026

mouseX = mouse.position.x

Enter (Virtual Joystick). When combined with a feeder tool like FreePIE or JoyToMouse , it transforms the horizontal movement of your mouse into a smooth, proportional steering axis. For many simulation games that are unplayable with a keyboard (e.g., Euro Truck Simulator 2 , Assetto Corsa , GTA V ), vJoy mouse steering offers a budget-friendly, high-precision alternative.

if starting: mouse.position = (screen_width/2, 500) # center mouse update() vjoy mouse steering

Unlike a physical joystick that springs back to center, a mouse has no physical center. If you move the mouse left, the cursor goes left and stays there. For steering, you need the wheel to return to center when you stop moving the mouse.

# Mouse button 4 (forward side button) = Gas if mouse.getButton(4): vJoy[0].axisY = 100 # Full throttle else: vJoy[0].axisY = 0 mouseX = mouse

If you have $60, buy a used Logitech Driving Force GT. But if you have $0, is the best free upgrade for your racing game library.

| Parameter | Effect | Recommended Range | |-----------|--------|-------------------| | | Higher = less mouse movement for full lock | 8–20 (relative mode) | | Smoothing | Low-pass filter on mouse input | 0–2 frames average | | Deadzone | Ignore tiny mouse movements at center | 1–3% of axis range | | Return-to-center | In relative mode, manually drag mouse back | Not auto (use absolute mode for auto-center) | | Non-linearity | S-curve steering response | Use game’s built-in steering curve | if starting: mouse
