Hey everyone! I've recently started exploring game development, and I'm working on a terminal-based version of Space Invaders. I've run into an annoying issue with keyboard input delay—specifically, the lag that occurs when I hold down a key before it starts repeating. I'm curious why this delay happens in my terminal setup when there's none in web games, which provide a smooth stream of input. Does anyone know how to fix this delay, especially if there are any Rust crates that could help? Thanks a lot!

The keyboard delay might not be an issue with your code but rather a setting in your operating system or terminal emulator. Check the specific instructions for your setup to adjust the key hold delay settings. It’s worth a look!
Instead of just detecting key presses, consider implementing a "button box" approach, similar to what you see in browsers. Use 'key down' and 'key up' events to track when a key is held down, which can provide a smoother experience.
To tackle that keyboard input delay, you should try using RAW input. A great Rust crate for this is 'crossterm'. It helps manage terminal inputs more effectively and reduces the delay you’re experiencing.
You might want to look into scancodes if you're diving deeper into input management. They can offer better control over how your program reacts to key events.
