物体拾取
1.世界构筑的起始篇章-编辑器
- Unity 2022.3.62f2：
- Visual Studio 2022
2.光芒汇聚之所-章节目标
- 射线检测拾取物体
- 鼠标点击拾取物体
3.光流影卷-演示视频
4.初始祭坛-前置准备
导入资源(天空球，描边，道具模型)
5.勇者行迹录-章节任务
5.1 创建StudyCase3
- 复制场景和脚本改名为StudyCase3
- 修改控制器的命名空间
5.2 道具
- 把导入的道具模型放到场景中
- 新建道具层级
- 在
Assets\Scripts\StudyCase3下创建道具脚本Item.cs
using UnityEngine;
namespace StudyCase3
{
public class Item : MonoBehaviour
{
Outline outline;
bool pick;
ThirdCharacterController player;
private void Awake()
{
player = FindAnyObjectByType<ThirdCharacterController>();
if (outline == null)
outline = gameObject.AddComponent<Outline>();
else
outline = GetComponent<Outline>();
outline.enabled = false;
outline.OutlineMode = Outline.Mode.OutlineVisible;
outline.OutlineColor = new Color(0, 1, 1);
outline.OutlineWidth = 10f;
gameObject.layer = LayerMask.NameToLayer("Item");
}
public void Select()
{
if(!pick)
outline.enabled = true;
}
public void UnSelect()
{
if (!pick)
outline.enabled = false;
}
public void PickUp(Transform root)
{
if (pick) return;
pick = true;
transform.SetParent(root);
outline.OutlineWidth = 2f;
gameObject.layer = LayerMask.NameToLayer("Default");
player.SetItems();
}
private void OnMouseEnter()
{
if (player.pickMode == PickMode.Mouse)
Select();
}
private void OnMouseExit()
{
if (player.pickMode == PickMode.Mouse)
UnSelect();
}
private void OnMouseDown()
{
if (player.pickMode == PickMode.Mouse)
PickUp(player.itemRoot);
}
}
}
- 道具挂载脚本
- 创建Pick输入事件，绑定按键F
5.3 Player脚本和设置

- 玩家挂载脚本，创建ItemRoot节点，设置射线检测层级
