Usage

Example of getting key state (even if current window is inactive)

package main

import (
	"github.com/Numenorean/keypresses"
	"time"
	"fmt"
)

func main() {
  for true {
    // 0x50 is virtualKeyCode, char "P" in human format
    fmt.Println(keypresses.IsKeyPressed(0x50))
    // Sleeping to prevent 100% CPU usage
    time.Sleep(1 * time.Microsecond)
  }
}

Example of getting key state only if current window is active

package main

import (
	"github.com/Numenorean/keypresses"
	"time"
	"fmt"
)

func main() {
  for true {
    // "false" argument means that to get key state, window should be active
    // "true" argument means that to get key state, window might not be active. The same as an IsKeyPressed function
    fmt.Println(keypresses.IsKeyPressedGlobal(0x50, false))
    // Sleeping to prevent 100% CPU usage
    time.Sleep(1 * time.Microsecond)
  }
}
