Auto Clicker

A high-precision, lightweight Windows desktop auto clicker written in C# using .NET 8 and WPF.

Features

• Native Windows Mouse Injection: Built on Win32 SendInput API for low latency and reliable input.
• High Precision Timer: Utilizes winmm.dll 1ms system timer precision and Stopwatch microsecond timing.
• Interval Breakdown: Configure click intervals in Hours, Minutes, Seconds, and Milliseconds with automatic CPS calculation.
• Humanized CPS Jitter: Optional Min/Max CPS range using Gaussian normal distribution to simulate natural clicking.
• Click Options: Supports Left, Right, and Middle mouse buttons, as well as Single and Double clicks.
• Repeat Controls: Choose between repeating until stopped manually or stopping automatically after a specified click count.
• Cursor Positioning: Operates at the current mouse cursor location or locks to fixed screen coordinates (X/Y).
• Hotkey Activation Modes:
  • Toggle Mode: Press hotkey once to start, press again to stop.
  • Hold Mode: Active only while holding down the hotkey.
• System-Wide Hotkey Hook: Global low-level keyboard and mouse hooks (SetWindowsHookEx) supporting standard keys (F1-F12, letters) and mouse side buttons (Mouse 4 / Mouse 5).
• Window Filtering: Optional filter to execute clicks only when a targeted process (e.g., Minecraft) is focused.
• Dark Grayscale Interface: Minimalist utility UI with custom-styled dark controls (ComboBoxes, CheckBoxes, RadioButtons, Sliders, and ScrollBars).
