Raycast Hit raycastHit

Unity中的Layers一共有32个，索引用0到31表示。 public static bool Raycast(Ray ray, out RaycastHit hitInfo, float maxDistance, int layerMask) { return Raycast(ray.origin, ray.direction, out hitInfo, maxDistance, layerMask, QueryTriggerInteraction.UseGlobal); } ray光线的起点和方向 hitInfo 如果返回 true，则 hitInfo 将包含有关最近的碰撞体的命中位置的更多信息 maxDistance 射线应检查碰撞的最大距离 layerMask 层遮罩，用于在投射射线时有选择地忽略碰撞体 参数layerMask int layerMask; layerMask = 1 << 指定检测的层级; layerMask = 0 << 忽略检测的层级; 代码示例 int layerMask; void Start() { layerMask = 1 << 0;...

Today I'm starting a new series of short posts about neat C# features that many Unity game developers are missing on. In this post, you will learn about the improved Unity C# out Parameters feature that is available since C# 7.0. When programming your game, you'll often run into the need of returning multiple values within from a function. Traditionally speaking, you have several ways to return multiple values.
