嗨,我目前正试图创建一个程序,移动光标从一个给定的点到另一个平滑的随机运动。我目前使用CoreGraphics创建了以下内容,它可以工作,但鼠标移动变得非常不稳定。对如何解决这个问题有什么想法吗?感谢。我在我的Mac OS X应用程序开始时在applicationDidFinishLaunching中调用以下代码:
var pos = NSEvent.mouseLocation()
pos.y = NSScreen.mainScreen()!.frame.height - pos.y
moveMouse(CGPoint(x:200,y:200), from: pos)
这些是我创建的函数:
func transMouse(point:CGPoint) {
let move = CGEventCreateMouseEvent(nil, CGEventType.MouseMoved, point, CGMouseButton.Left)
CGEventPost(CGEventTapLocation.CGHIDEventTap, move)
}
func moveMouseOne(direction:Character, _ currentPos:CGPoint) -> CGPoint {
var newPos = currentPos
if direction == "r" {
newPos.x = currentPos.x + 1
} else if direction == "l" {
newPos.x = currentPos.x - 1
} else if direction == "u" {
newPos.y = currentPos.y - 1
} else if direction == "d" {
newPos.y = currentPos.y + 1
}
transMouse(newPos)
return newPos
}
func moveMouse(to:CGPoint, from:CGPoint) -> CGPoint {
let dx:Int = Int(to.x - from.x)
let dy:Int = Int(to.y - from.y)
var moves = Array<Character>()
if dx > 0 {
for _ in 0..<dx {
moves.append("r")
}
} else {
for _ in 0..<(-dx) {
moves.append("l")
}
}
if dy > 0 {
for _ in 0..<dy {
moves.append("d")
}
} else {
for _ in 0..<(-dy) {
moves.append("u")
}
}
var pos = from
let delay:Double = 0.0008
let startTime = DISPATCH_TIME_NOW
for var i = 0; i < moves.count; ++i {
let time = dispatch_time(startTime, Int64(delay * Double(i) * Double(NSEC_PER_SEC)))
dispatch_after(time, dispatch_get_main_queue()) {
let count = moves.count
let random = Int(arc4random_uniform(UInt32(count)))
pos = self.moveMouseOne(moves[random], pos)
if random == count - 1 {
moves.popLast()
} else {
moves[random] = moves.popLast()!
}
}
}
return to
}
我非常推荐使用Core Animation来做这样的事情,这会节省你很多的时间和精力。
