Question

很抱歉感到尴尬，但我可以获得有关如何执行此操作的完整代码：

我希望在我的游戏中每个子弹射击后延迟1秒，以防止子弹垃圾邮件。如果可能的话，如果没有为子弹产生创建单独的函数，就像我在touchesEnded中所做的那样。所以轻拍，拍摄，等待。点击，拍摄，等待。在等待中，如果点击屏幕，则没有任何反应。谢谢，对不起我是初学者

guard let touch = touches.first else {
        return
    }
    let touchLocation = touch.location(in: self)

    //Set up initial location of bullet and properties
    let bullet = SKSpriteNode(imageNamed: "bullet")
    bullet.name = "Bullet"
    bullet.position = player.position
    bullet.setScale(0.75)
    bullet.zPosition = 1
    bullet.physicsBody = SKPhysicsBody(circleOfRadius: bullet.size.width/2)
    bullet.physicsBody?.isDynamic = true
    bullet.physicsBody?.categoryBitMask = PhysicsCategory.Projectile
    bullet.physicsBody?.contactTestBitMask = PhysicsCategory.Monster
    bullet.physicsBody?.collisionBitMask = PhysicsCategory.None
    bullet.physicsBody?.usesPreciseCollisionDetection = true



    //Determine offset of location to bullet
    let offset = touchLocation - bullet.position

    //Stops Bullet from shooting backwards
    if (offset.y < 0) { return }

    addChild(bullet)

    //Get the direction of where to shoot
    let direction = offset.normalized()

    //Make it shoot far enough to be guaranteed off screen
    let shootAmount = direction * 1000

    //Add the shoot amount to the current position
    let realDest = shootAmount + bullet.position

    //Create the actions

    if currentGameState == gameState.inGame {
    let actionMove = SKAction.move(to: realDest, duration: 1.2)
    let actionMoveDone = SKAction.removeFromParent()
    bullet.run(SKAction.sequence([actionMove, actionMoveDone]))
    }

}

试试这个：

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  constructor(private my: string) {}
}

这意味着每次发射子弹时，会发生1秒的计时器，这会阻止子弹代码在时间结束前运行。此时，布尔值切换回false，允许再次运行代码。

Swift Timer检查TouchesEnded
