我正在使用swift構建一款遊戲遊戲。目標是避免進入的寶石，並隨着關卡的增加獲得儘可能多的積分。石頭撞向船隻的方向相反。但我無法察覺船與石之間的碰撞，石頭穿過船。船可以向左或向右移動。我正在用swift構建一個遊戲遊戲。無法檢測到衝突
我用rect1.interects（rect2）作爲交集。
謝謝。
這裏是ViewController.swift
import UIKit

boat.frame = CGRect(x: 0, y: 0, width: 60, height: 90)
boat.frame.origin.y = self.view.bounds.height - boat.frame.size.height - 10

self.view.insertSubview(boat, aboveSubview: moveWater)

func movingStone() {

有許多問題，我可以在你的方法見： - 缺少遊戲主循環，每個遊戲的實體將關於獲得至少更新到位置 - 混合幀座標 - 碰撞將不得不從頭開始做的， uiview.bounds不一定與用戶體驗視角衝突盒中的優化重疊 我推薦的是： - 查找一些教程如何設計遊戲 - 切換到SpriteKit，它會給你「物理」免費 –
爲什麼我不能使用碰撞檢測。我不知道爲什麼我無法檢測到碰撞！ –
使用框架，您只能輕鬆檢測到矩形碰撞，如果您將碰撞矩形設置得很小（比我認爲的小），但無法檢測到以此方式相交的自定義形狀。 –
