UIButtons
はSKScene
ではうまく機能しないことがわかっているので、SKNode
にボタンを作成するためにSpriteKit
をサブクラス化しようとしています。
SKScene
でボタンを初期化し、タッチイベントを有効にすると、ボタンは押されたときにSKScene
でメソッドを呼び出します。
この問題の解決策を見つけるためのアドバイスをいただければ幸いです。ありがとう。
sKSpriteNodeをボタンとして使用し、ユーザーがタッチしたときに、そのノードがタッチされたかどうかを確認できます。 SKSpriteNodeのnameプロパティを使用して、ノードを識別します。
//fire button
- (SKSpriteNode *)fireButtonNode
{
SKSpriteNode *fireNode = [SKSpriteNode spriteNodeWithImageNamed:@"fireButton.png"];
fireNode.position = CGPointMake(fireButtonX,fireButtonY);
fireNode.name = @"fireButtonNode";//how the node is identified later
fireNode.zPosition = 1.0;
return fireNode;
}
シーンにノードを追加します。
[self addChild: [self fireButtonNode]];
ハンドルタッチ:
//handle touch events
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
//if fire button touched, bring the rain
if ([node.name isEqualToString:@"fireButtonNode"]) {
//do whatever...
}
}
作業している独自のButton-Classを作成しました。 SKButton.h:

例:ボタンを初期化するには、次の行を記述します。
SKButton *backButton = [[SKButton alloc] initWithImageNamedNormal:@"buttonNormal" selected:@"buttonSelected"];
[backButton setPosition:CGPointMake(100, 100)];
[backButton.title setText:@"Button"];
[backButton.title setFontName:@"Chalkduster"];
[backButton.title setFontSize:20.0];
[backButton setTouchUpInsideTarget:self action:@selector(buttonAction)];
[self addChild:backButton];
さらに、クラスに「buttonAction」メソッドが必要です。 *このクラスがすべての場合に正しく機能するという保証はありません。私はまだObjective-cにまったく新しいです。*
これを行うのは面倒で無意味だと思う場合は、「objc_msgSend Calls'
の厳密なチェックを有効にする」を「No
」に設定して、ビルド設定のチェックを無効にできます。
Swiftでゲームを書いている人のために! Grafのソリューションの重要な部分をSwiftクラスに書き直しました。それが役に立てば幸い:

必要に応じて、can UIButton(または他のUIView)を使用します。
SKScene
が作成されたとき、SKView
にはまだ存在していません。 SKScene
サブクラスにdidMoveToView:
を実装する必要があります。この時点で、シーンが配置されているSKView
にアクセスでき、UIKit
オブジェクトを追加できます。可愛さのために、私はそれらをフェードインしました…
- (void)didMoveToView:(SKView *)view {
UIView *b = [self _createButton]; // <-- performs [self.view addSubview:button]
// create other UI elements, also add them to the list to remove …
self.customSubviews = @[b];
b.alpha = 0;
[UIView animateWithDuration:0.4
delay:2.4
options:UIViewAnimationOptionCurveEaseIn
animations:^{
b.alpha = 1;
} completion:^(BOOL finished) {
;
}];
}
もちろん、それらがそこにとどまることが完全に理にかなっていない限り、移行するときにそれらを意図的にシーンから削除する必要があります。
- (void)removeCustomSubviews {
for (UIView *v in self.customSubviews) {
[UIView animateWithDuration:0.2
delay:0
options:UIViewAnimationOptionCurveEaseIn
animations:^{
v.alpha = 0;
} completion:^(BOOL finished) {
[v removeFromSuperview];
}];
}
}
プログラムでUIButton
を作成することに慣れていない人のために、ここに1つの例(ここでは100のことを別の方法で行うことができます)…
- (UIButton *)_createButton {
UIButton *b = [UIButton buttonWithType:UIButtonTypeCustom];
[b setTitle:@"Continue" forState:UIControlStateNormal];
[b setBackgroundImage:[UIImage imageNamed:@"GreenButton"] forState:UIControlStateNormal];
[b setBackgroundImage:[UIImage imageNamed:@"GreenButtonSelected"] forState:UIControlStateHighlighted];
b.titleLabel.adjustsFontSizeToFitWidth = YES;
b.titleLabel.font = [UIFont fontWithName:@"HelveticaNeue-Bold" size:36];
b.frame = CGRectMake(self.size.width * .7, self.size.height * .2, self.size.width * .2, self.size.height * .1);
[b addTarget:self action:@selector(continuePlay) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:b];
return b;
}
注意:UIView
Originは左上にあり、SKScene
Originは左下にあります。
Graf でSKButtonクラスを使用しました。
SKButtonを使用してシーンナビゲーションを行います。つまり、ユーザーがSKButtonを押したときに別のシーンを表示します。 EXC_BAD_ACCESS
でtouchesEnded->[self setIsSelected:NO]
エラーが発生します。これは、高速のCPUを搭載した最新のiPadで特に頻繁に発生します。
確認とトラブルシューティングを行った後、setIsSelected
関数が呼び出されたときにSKButtonオブジェクトが既に「割り当て解除されている」ことに気付きました。これは、SKButtonを使用して次のシーンに移動するためです。これは、現在のシーンの割り当てをいつでも解除できることも意味します。
次のように「else」部分にsetIsSelectedを配置することで、小さな変更を加えました。
これが、同じエラーを見ている他の開発者にも役立つことを願っています。
(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint touchPoint = [touch locationInNode:self.parent];
if ([self isEnabled] && CGRectContainsPoint(self.frame, touchPoint)) {
objc_msgSend(_targetTouchUpInside, _actionTouchUpInside);
} else {
[self setIsSelected:NO];
}
objc_msgSend(_targetTouchUp, _actionTouchUp);
}
編集:SKButtonNodeのgithubリポジトリを作成し、Swiftの進化に合わせて最新の状態に保ち、更新することを期待しています。
残念ながら、SwiftでのSKButtonのFilipのSwift実装についてはまだコメントできません。彼がSwiftでこれを作ったことをとても嬉しく思います!しかし、ボタンにテキストを追加する機能が含まれていないことに気付きました。これは私にとって非常に大きな機能です。そのため、ボタンごとに個別のアセットを作成する必要はなく、背景だけでダイナミックテキストを追加する必要があります。
テキストラベルをSKButtonに追加する簡単な関数を追加しました。それは完璧ではない可能性が高いです。私はSwiftが初めてで、他のみんなと同じです!気軽にコメントして、これをできる限り更新するのを手伝ってください。皆さんのように!

この問題に対するなんと素晴らしい解決策でしょう!ここまでやってくるハードコアなスクローラーには、お楽しみに!私はSKScene

let data = ButtonData(button: node, actionToPerform: handler)
eligibleButtons.append(data)

//TODO: make a dictionary with ()->() as the value and SKNode as the key.
//Then refactor this class!

let actionToPerform:()->()

let button:SKNode
let originalButtonFrame:CGRect

for touch in touches {
let touchLocation = touch.location(in: self)
let touchedNode = atPoint(touchLocation)
for buttonData in eligibleButtons {
if touchedNode === buttonData.button {
//then this touch needs to be tracked, as it touched down on an eligible button!
for (t, bD) in trackedTouches {
if bD.button === buttonData.button {
//then this button was already being tracked by a previous touch, disable the previous touch
trackedTouches[t] = nil
}
}
//start tracking this touch
trackedTouches[touch] = TouchTrackingData(button: touchedNode, originalButtonFrame: touchedNode.frameInScene)
applyTouchedDownEffectToNode(node: buttonData.button)
}
}
}
}
//------------------------------------------------------------------------------------

}
これにはまだ実装していない多くのアイデアとコードの説明が含まれていますが、コピーしてプロジェクトに貼り付けるだけで、自分のシーンでそのまま使用できます。完全な使用例は次のとおりです。
class GameScene : KCScene {
var playButton:SKSpriteNode
override init(size:CGSize) {
playButton = SKSpriteNode(color: SKColor.red, size: CGSize(width:200,height:200))
playButton.position.x = size.width/2
playButton.position.y = size.height*0.75
super.init(size: size)
}
override func didMove(to view: SKView) {
addChild(playButton)
addButton(playButton, withCompletionHandler: playButtonPushed)
}
func playButtonPushed() {
let scene = GameScene(size: CGSize(width: 768, height: 1024))
scene.scaleMode = .aspectFill
view!.presentScene(scene)
}
}
1つの注意点は、touchesBegan
、touchesMoved
、touchesEnded
、および/またはtouchesCancelled
を実装する場合、スーパーを呼び出す必要があることです。それ以外の場合は動作しません。
そして、その例では、NODE UIButton
特性を与えるために必要なコードは実際には1行だけであることに注意してください。次の行でした:
addButton(playButton, withCompletionHandler: playButtonPushed)
私は常にアイデアや提案を受け付けています。コメントとハッピーコーディングに残してください!!
おっと、この気の利いた拡張機能を使用していることを忘れていました。 (おそらくすべてのノードで必要ではないので)拡張機能からそれを取り出して、私のクラスに組み込むことができます。私は1か所でしか使用しません。
extension SKNode {
var frameInScene:CGRect {
if let scene = scene, let parent = parent {
let rectOriginInScene = scene.convert(frame.Origin, from: parent)
return CGRect(Origin: rectOriginInScene, size: frame.size)
}
return frame
}
}
これは、FilipのSwiftコードに基づいた別のバージョンです。私はそれを少し単純化し、セレクターだけでなくブロックを取ることを許可しました:

callTarget(act)
}
}
override func touchesMoved(touches: NSSet, withEvent event: UIEvent) {
if (!isEnabled) {
return
}
let touch: AnyObject! = touches.anyObject()
let touchLocation = touch.locationInNode(parent)
if (CGRectContainsPoint(frame, touchLocation)) {
isSelected = true
} else {
isSelected = false
}
}
override func touchesEnded(touches: NSSet, withEvent event: UIEvent) {
if (!isEnabled) {
return
}
isSelected = false
let touch: AnyObject! = touches.anyObject()
let touchLocation = touch.locationInNode(parent)
if (CGRectContainsPoint(frame, touchLocation) ) {
if let act = actionTouchUpInside {
callTarget(act)
}
}
if let act = actionTouchUp {
callTarget(act)
}
}
}
次のように使用します。
aFTButton.actionTouchUpInside = FTButtonTarget.aBlock({ () -> Void in
println("button touched")
})
お役に立てれば。
クロージャーを使用して、Swiftで完全に記述されたこの問題を解決するための私のソリューション。
使い方はとても簡単です! https://github.com/txaidw/TWControls
class Test {
var testProperty = "Default String"
init() {
let control = TWButton(normalColor: SKColor.blueColor(), highlightedColor: SKColor.redColor(), size: CGSize(width: 160, height: 80))
control.position = CGPoint(x: CGRectGetMidX(self.frame), y: CGRectGetMidY(self.frame))
control.position.allStatesLabelText = "PLAY"
control.addClosureFor(.TouchUpInside, target: self, closure: { (scene, sender) -> () in
scene.testProperty = "Changed Property"
})
}
deinit { println("Class Released..") }
}
かなり前に、SKSpriteNodeをボタンとして使用するためのクラスを作成していました。 GitHubで見つけることができます。
実装はUIButtonに基づいているため、すでにiOSに精通している場合は、簡単に操作できるはずです。
ボタンを押したときに実行されるブロックまたはSKActionを割り当てることもできます。
ラベルを設定する方法も含まれています。
通常、ボタンは次のように宣言されます。
AGSpriteButton *button = [AGSpriteButton buttonWithColor:[UIColor redColor] andSize:CGSizeMake(300, 100)];
[button setLabelWithText:@"Button Text" andFont:nil withColor:nil];
button.position = CGPointMake(self.size.width / 2, self.size.height / 3);
[button addTarget:self selector:@selector(someSelector) withObject:nil forControlEvent:AGButtonControlEventTouchUpInside];
[self addChild:button];
以上です。あなたは行ってもいいです。
私は上記のオプションのいずれも確信していなかったので、私が作成した最新のSwift4に基づいて 自分のソリューション を作成しました。
以下は、最新のSwift(4.1.2)で書かれたシンプルなボタンです。
特徴
touchBeganCallback
およびtouchEndedCallback
クロージャーを設定してカスタム動作を追加できますimport SpriteKit
class SpriteKitButton: SKSpriteNode {
private let textureDefault: SKTexture
private let textureActive: SKTexture
init(defaultImageNamed: String, activeImageNamed:String) {
textureDefault = SKTexture(imageNamed: defaultImageNamed)
textureActive = SKTexture(imageNamed: activeImageNamed)
super.init(texture: textureDefault, color: .clear, size: textureDefault.size())
self.isUserInteractionEnabled = true
}
required init?(coder aDecoder: NSCoder) {
fatalError("Not implemented")
}
var touchBeganCallback: (() -> Void)?
var touchEndedCallback: (() -> Void)?
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
self.texture = textureActive
touchBeganCallback?()
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
self.texture = textureDefault
touchEndedCallback?()
}
}
class GameScene: SKScene {
override func didMove(to view: SKView) {
// 1. create the button
let button = SpriteKitButton(defaultImageNamed: "default", activeImageNamed: "active")
// 2. write what should happen when the button is tapped
button.touchBeganCallback = {
print("Touch began")
}
// 3. write what should happen when the button is released
button.touchEndedCallback = {
print("Touch ended")
}
// 4. add the button to the scene
addChild(button)
}
}
実際、これはSwift 2.2でうまく機能しますXcode 7.3
FTButtonNode( richy486/FTButtonNode.Swift )が好きですが、別のサイズを指定することはできません(デフォルトのテクスチャサイズではありません)初期化中に直接、この簡単なメソッドを追加しました:
公式のカスタムinitメソッド(これに似ています)の下でそれをコピーして、使用する別のinitメソッドを用意する必要があります。
init(normalTexture defaultTexture: SKTexture!, selectedTexture:SKTexture!, disabledTexture: SKTexture?, size:CGSize) {
self.defaultTexture = defaultTexture
self.selectedTexture = selectedTexture
self.disabledTexture = disabledTexture
self.label = SKLabelNode(fontNamed: "Helvetica");
super.init(texture: defaultTexture, color: UIColor.whiteColor(), size: size)
userInteractionEnabled = true
//Creating and adding a blank label, centered on the button
self.label.verticalAlignmentMode = SKLabelVerticalAlignmentMode.Center;
self.label.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.Center;
addChild(self.label)
// Adding this node as an empty layer. Without it the touch functions are not being called
// The reason for this is unknown when this was implemented...?
let bugFixLayerNode = SKSpriteNode(texture: nil, color: UIColor.clearColor(), size: size)
bugFixLayerNode.position = self.position
addChild(bugFixLayerNode)
}
もう1つの重要なことは「選択時間」です。新しいデバイス(iPhone 6)では、touchesBegan
とtouchesEnded
の間の時間が速すぎて、defaultTexture
およびselectedTexture
。
この機能では:
func dispatchDelay(delay:Double, closure:()->()) {
dispatch_after(
dispatch_time(
DISPATCH_TIME_NOW,
Int64(delay * Double(NSEC_PER_SEC))
),
dispatch_get_main_queue(), closure)
}
touchesEnded
メソッドを書き直して、テクスチャのバリエーションを正しく表示できます。
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
if (!isEnabled) {
return
}
dispatchDelay(0.2) {
self.isSelected = false
}
if (targetTouchUpInside != nil && targetTouchUpInside!.respondsToSelector(actionTouchUpInside!)) {
let touch: AnyObject! = touches.first
let touchLocation = touch.locationInNode(parent!)
if (CGRectContainsPoint(frame, touchLocation) ) {
UIApplication.sharedApplication().sendAction(actionTouchUpInside!, to: targetTouchUpInside, from: self, forEvent: nil)
}
}
if (targetTouchUp != nil && targetTouchUp!.respondsToSelector(actionTouchUp!)) {
UIApplication.sharedApplication().sendAction(actionTouchUp!, to: targetTouchUp, from: self, forEvent: nil)
}
}
そして、私たち全員がiOSをターゲットにしているわけではないので、ここでMacでのマウスインタラクションを処理するために書いたコードの一部を紹介します。
教祖への質問:トラックパッドを使用する場合、MacOSはタッチイベントを提供しますか?または、これらはマウスイベントとしてSpriteKitに送信されますか?
教祖への別の質問です。このクラスを適切にSKButtonと呼ぶべきではありませんNode?
とにかく、これを試してください...
#if os(iOS)
override func touchesBegan(touches: NSSet!, withEvent event: UIEvent!) {
let touch: AnyObject! = touches.anyObject()
let touchLocation = touch.locationInNode(parent)
if (!isEnabled) { return }
isSelected = true
if (targetTouchDown != nil && targetTouchDown!.respondsToSelector(actionTouchDown!)) {
UIApplication.sharedApplication().sendAction(actionTouchDown!, to: targetTouchDown, from: self, forEvent: nil)
}
}
override func touchesMoved(touches: NSSet!, withEvent event: UIEvent!) {
if (!isEnabled) { return }
let touch: AnyObject! = touches.anyObject()
let touchLocation = touch.locationInNode(parent)
if (CGRectContainsPoint(frame, touchLocation)) {
isSelected = true
} else {
isSelected = false
}
}
override func touchesEnded(touches: NSSet!, withEvent event: UIEvent!) {
if (!isEnabled) { return }
isSelected = false
if (targetTouchUpInside != nil && targetTouchUpInside!.respondsToSelector(actionTouchUpInside!)) {
let touch: AnyObject! = touches.anyObject()
let touchLocation = touch.locationInNode(parent)
if (CGRectContainsPoint(frame, touchLocation) ) {
UIApplication.sharedApplication().sendAction(actionTouchUpInside!, to: targetTouchUpInside, from: self, forEvent: nil)
}
}
if (targetTouchUp != nil && targetTouchUp!.respondsToSelector(actionTouchUp!)) {
UIApplication.sharedApplication().sendAction(actionTouchUp!, to: targetTouchUp, from: self, forEvent: nil)
}
}
#else
// FIXME: needs support for mouse enter and leave, turning on and off selection
override func mouseDown(event: NSEvent) {
if (!isEnabled) { return }
if (targetTouchDown != nil && targetTouchDown!.respondsToSelector(actionTouchDown!)) {
NSApplication.sharedApplication().sendAction(actionTouchDown!, to: targetTouchDown, from: self)
}
}
override func mouseUp(event: NSEvent) {
if (!isEnabled) { return }
if (targetTouchUpInside != nil && targetTouchUpInside!.respondsToSelector(actionTouchUpInside!)) {
let touchLocation = event.locationInNode(parent)
if (CGRectContainsPoint(frame, touchLocation) ) {
NSApplication.sharedApplication().sendAction(actionTouchUpInside!, to: targetTouchUpInside, from: self)
}
}
if (targetTouchUp != nil && targetTouchUp!.respondsToSelector(actionTouchUp!)) {
NSApplication.sharedApplication().sendAction(actionTouchUp!, to: targetTouchUp, from: self)
}
}

残念ながら、SpriteKitにはボタンノードがありません。非常に便利なコントロールなので、理由はわかりません。だから、CocoaPods経由で自分で作成して共有することにしました。それを使用してください OOButtonNode 。ボタンは、Swiftで書かれたテキスト/背景または画像を使用できます4。
私はSKScene
クラスをサブクラス化し、このプロジェクトでボタンタップを解決する問題を達成しました。
https://github.com/Prasad9/SpriteKitButton
その中で、タップ時に知る必要があるすべてのノードに名前を付ける必要があります。
このプロジェクトでは、ボタンタップの検出に加えて、特定のノードのタッチが開始または終了したかどうかを検出することもできます。
タップアクションを取得するには、シーンファイルで次のメソッドをオーバーライドします。
- (void)touchUpInsideOnNodeName:(NSString *)nodeName atPoint:(CGPoint)touchPoint {
// Your code here.
}
特定のボディのタッチの開始を知るには、シーンファイルで次のメソッドをオーバーライドします。
- (void)touchBeginOnNodeName:(NSString *)nodeName {
// Your code here.
}
特定のボディのタッチの終わりを知るには、Sceneファイルで次のメソッドをオーバーライドします。
- (void)touchEndedOnNodeName:(NSString *)nodeName {
// Your code here.
}
Grafのソリューションには1つの問題があります。例えば:
self.pauseButton = [[AGSKBButtonNode alloc] initWithImageNamed:@"ButtonPause"];
self.pauseButton.position = CGPointMake(0, 0);
[self.pauseButton setTouchUpInsideTarget:self action:@selector(pauseButtonPressed)];
[_hudLayer addChild:_pauseButton];
_hudLayerは、私のシーンのプロパティであるSKNodeです。したがって、SKButtonのメソッドtouchesEndedにより、例外が発生します。シーンではなく[SKSpriteNode pauseButtonPressed]を呼び出します。
Self.parentをタッチターゲットに変更するソリューション:
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint touchPoint = [touch locationInNode:self.parent];
if ([self isEnabled] && CGRectContainsPoint(self.frame, touchPoint)) {
if (_actionTouchUpInside){
[_targetTouchUpInside performSelectorOnMainThread:_actionTouchUpInside withObject:_targetTouchUpInside waitUntilDone:YES];
}
}
[self setIsSelected:NO];
if (_actionTouchUp){
[_targetTouchUp performSelectorOnMainThread:_actionTouchUp withObject:_targetTouchUp waitUntilDone:YES];
}}
