SpriteKit MouseMoved无效

Question

我知道之前已经问过这个问题，但我认为答案可能需要更新，因为它目前在使用Xcode 8.3.3 for Mac OS的SpriteKit中无效。在阅读了这个post之后，我意识到在AppDelegate中曾经可以完成的任务现在应该在ViewController中完成，但是它不起作用。任何人都有任何建议，为什么这不起作用？这是我的各种类的样子：

ViewController.m

#import "ViewController.h"
#import "GameScene.h"

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Load the SKScene from 'GameScene.sks'
    GameScene *scene = (GameScene *)[SKScene nodeWithFileNamed:@"GameScene"];

    // Set the scale mode to scale to fit the window
    scene.scaleMode = SKSceneScaleModeAspectFill;

    // Present the scene
    [self.skView presentScene:scene];

    self.skView.showsFPS = YES;
    self.skView.showsNodeCount = YES;

    //added in hopes that mouse moved events would be captured
    [self.skView.window setAcceptsMouseMovedEvents:YES];
    [self.skView.window setInitialFirstResponder:self.skView];
}

@end

GameScene.m

#import "GameScene.h"

@implementation GameScene

- (void)didMoveToView:(SKView *)view {

}

-(void) mouseMoved:(NSEvent *)event {
    NSLog(@"blah");
}

-(void)update:(CFTimeInterval)currentTime {
    // Called before each frame is rendered
}

@end

您要将第一响应者设置为skView，您需要将其设置为skView.scene，以便鼠标响应您的场景实例，而不是您的视图实例。

第1步：将您的窗口代码移至viewDidAppear

第2步：使用[self.skView.window makeFirstResponder:self.skView.scene];

将第一响应者更改为场景

您需要在viewDidAppear事件中执行此操作的原因是因为window SKView nil期间viewDidLoad self.skView.window!.setsAcceptedMouseMovements = true #import "ViewController.h" #import "GameScene.h" @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Load the SKScene from 'GameScene.sks' GameScene *scene = (GameScene *)[SKScene nodeWithFileNamed:@"GameScene"]; // Set the scale mode to scale to fit the window scene.scaleMode = SKSceneScaleModeAspectFill; // Present the scene [self.skView presentScene:scene]; self.skView.showsFPS = YES; self.skView.showsNodeCount = YES; } - (void) viewDidAppear { //added in hopes that mouse moved events would be captured [self.skView.window setAcceptsMouseMovedEvents:YES]; [self.skView.window setInitialFirstResponder:self.skView]; [self.skView.window makeFirstResponder:self.skView.scene]; } @end {{1}}如果你在Swift中做到这一点，那么{{1}}就会失败（Swift是一种优秀的语言，我建议使用它）
