[Unity]建造放置系统BuildSystem

Build System

下载完毕，导入。

下面这个脚本，直接挂载到一个空物体，新建一个 3D物体 立方体，将其设置为 BuildGameObject变量的值（如下图所示）。新建一个 按钮button，来触发placeBool函数即可 实现放置基本的物体。

using UnityEngine;
using BuildSystem;


public class BuildManage : MonoBehaviour {


    public Material ghostMaterial;//放置物体 时候的 材质
    private Material goMaterial;

    public KeyCode placeKey = KeyCode.Mouse0;


    [Tooltip("Key to press rotate (forward) the object based on snapRotaionDeg")]
    public KeyCode positiveRotateKey = KeyCode.Mouse1;


    [Tooltip("Key to press rotate (backward) the object based on snapRotaionDeg")]
    public KeyCode negativeRotateKey = KeyCode.None;


    [Header("More Settings")]
    [Tooltip("Disable the remover script when placer is active. Note: remover must be next to this script")]
    public bool shouldToggleRemover = true;


    [Tooltip("Max distance from camera where you can place objects")]
    public float maxPlaceDistance = 100f;
