Collision One of the most important mechanics in any game is collision—when two objects in your game world interact with each other. In hyperPad, you can set up collision behaviors to detect when your character hits an obstacle, enemy, or collectible. From there, you can trigger actions like losing health, collecting points, or changing scenes. For beginners, collision detection is a must-learn concept. hyperPad makes it easy with drag-and-drop behaviors, helping you create interactive and engaging gameplay without any coding required.
