touchesBegan Swift 2 custom SKSpriteKit Nodes

Question

I am new to creating games and such so as a practice I am making a silly game currently. This game has a briefcase which contains buttons (0-9) I would like to save the value of the number that was pressed in an array. I am unsure of how to use touches began to do a specific action if a specific type is pressed. ButtonInput:

class ButtonInput: SKSpriteNode{

var value: Int = 0

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

}
}

loadView():

let briefcase = ButtonInput(imageNamed: "briefcase")
    let Button0 = ButtonInput(imageNamed: "Button0")
    let Button1 = ButtonInput(imageNamed: "Button1")
    let Button2 = ButtonInput(imageNamed: "Button2")
    let Button3 = ButtonInput(imageNamed: "Button3")
    let Button4 = ButtonInput(imageNamed: "Button4")
    let Button5 = ButtonInput(imageNamed: "Button5")
    let Button6 = ButtonInput(imageNamed: "Button6")
    let Button7 = ButtonInput(imageNamed: "Button7")
    let Button8 = ButtonInput(imageNamed: "Button8")
    let Button9 = ButtonInput(imageNamed: "Button9")


    Button0.value = 0
    Button1.value = 1
    Button2.value = 2
    Button3.value = 3
    Button4.value = 4
    Button5.value = 5
    Button6.value = 6
    Button7.value = 7
    Button8.value = 8
    Button9.value = 9

UPDATE:

I tried making a touches began after hours of research and I came up with this:

    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {


    for touch: AnyObject! in touches {
        let touchLocation = touch.locationInNode(self)
        let touchedNode = self.nodeAtPoint(touchLocation)
        let name = touchedNode.name

            if name == "Button0"
            {
                userSequence.append(Button0.value)
                print("Button0 pressed")
            }
            if name == "Button1"
            {
                userSequence.append(Button1.getValue())
                print("Button1 pressed")
            }
            if name == "Button2"
            {
                userSequence.append(Button2.value)
            }
            if name == "Button3"
            {
                userSequence.append(Button3.value)
            }
            if name == "Button4"
            {
                userSequence.append(Button4.value)
            }
            if name == "Button5"
            {
                userSequence.append(Button5.value)
            }
            if name == "Button6"
            {
                userSequence.append(Button6.value)
            }
            if name == "Button7"
            {
                userSequence.append(Button7.value)
            }
            if name == "Button8"
            {
                userSequence.append(Button8.value)
            }
            if name == "Button9"
            {
                userSequence.append(Button9.value)
            }
            if name == "ButtonEnter"
            {
                compareSequences()
            }
    }


}

Answer 1

You should make buttons in the mainstoryboard, and connect them to the view controller. Then you can write the func for each button inside the connected actions

hope this helps

Answer 2

If you use SpriteKit, I would do something like this:

import SpriteKit

var _button = [SKSpriteNode]()

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

    for touch in touches {
        let location = touch.locationInNode(self)

        if(self.nodeAtPoint(location).name != nil && self.nodeAtPoint().name != "enter") {
            _array.append(self.nodeAtPoint(location).name)
        }
    }
}

func loadView() {

    for(var i = 0; i < 10; i++) {
        let tempButton = SKSpriteNode(imageNamed: "Button\(i)")
        tempButton.position = CGPoint(x: yourValue, y: yourValue)
        tempButton.size = CGSize(width: yourValue, height: yourValue)
        tempButton.name = "\(i)"
        temButton.zPosition = 2
        _button.append(tempButton)
        self.addChild(_button.last!)
    }

}

This will work if you have no other SKSpriteNode in the game because in the touches began I assume that the sprite touched has a number (0-9). To counter this problem, you could add an if statement to verify that the name is between 0-9.

Hope this help!
