i am brand new to swift and i am trying to program a pacman. i am trying to move the pacman to the direction of the swipe, so far i have managed to move it to the edges of the screen, the problem is that when i try to move it not from the edge of the screen but in the middle of the swipe action, it just goes to the edge of the screen and moves to the swipe direction, here is the code for one direction:
var x = view.center.x
for var i = x; i > 17; i--
{
var origin: CGPoint = self.view.center
var move = CABasicAnimation(keyPath:"position.x")
move.speed = 0.13
move.fromValue = NSValue(nonretainedObject: view.center.x)
move.toValue = NSValue(nonretainedObject: i)
view.layer.addAnimation(move, forKey: "position")
view.center.x = i
}
the thing is that i know the problem which is when i swipe to the direction that i want the for loop will not wait for the animation to stop but it will finish the loop in less than a second and i need sort of delay here or other code.
This was an interesting question, so I decided to make an example in SpriteKit. There isn't any collision detection, path finding or indeed even paths. It is merely an example of how to make 'Pac-Man' change direction when a swipe occurs.
I have included the GameScene below:
