Simple Crosshair Overlay

A simple native crosshair overlay without unnecessary bloat. Free and open-source software.

Features

• Works on any application that's not fullscreen exclusive. You must use windowed or borderless-windowed mode on your game. This was an intentional design choice, as rendering into a fullscreen-exclusive game is not anticheat-compatible.
• Performant: the overlay is only redrawn when you change the crosshair. CPU and memory usage are minimal, and the GPU isn't used at all.
• Minimal UI: managed via a tray icon and hotkeys.
• Comes with a simple default crosshair that can be scaled and recolored to your preference.
• Can use custom PNG images as crosshairs.
• No installer. The application is completely portable. The only file this program creates is small configuration saved in %appdata%\simple-crosshair-overlay.

Installation

1. Download simple-crosshair-overlay.exe from the latest release, and save it to a location of your choice
2. Run simple-crosshair-overlay.exe
3. Optionally, if you want a start menu shortcut you can make one yourself! Simply right-click simple-crosshair-overlay.exe and select "Pin to Start". This will automatically create a shortcut in %appdata%\Microsoft\Windows\Start Menu\Programs.

Binaries are also provided for MacOS, although they are untested. If you're interested in helping test see issue #3.

Linux is presently unsupported. See issue #6.

Usage

Use the tray icon to:

• Toggle crosshair visibility (you can also use Ctrl+H)
• Toggle Adjust Mode (you can also use Ctrl+J)
• Pick a color for the default crosshair (you can also use Ctrl+K).
• Load a PNG image as your crosshair
• Reset crosshair to default settings
• Safely exit the application and save your settings

In Adjust Mode:

• Arrow keys to move the crosshair
• PageUp/PageDown to increase/decrease the crosshair scale
• Ctrl+M to cycle through your monitors

Custom PNG Crosshairs

Your PNG file must use RGBA pixel format. Most PNGs are already saved this way, but you may need to specifically save it with an alpha channel if Simple Crosshair Overlay is giving you an error.

Also note that changing the color of the built-in crosshair has no effect on custom PNG crosshairs. If you want your custom crosshair in a different color you'll have to make that change in an image editor.

Changing Hotkeys

Hotkeys cannot currently be changed in-application. To edit your hotkeys, do the following:

1. Open the config file %appdata%\simple-crosshair-overlay\config\config.toml. If this file does not exist, starting and exiting the program once will create it.
2. Change hotkeys in the key_bindings section by referencing the Keycode values defined in keycode.rs
