【不用找素材】ECS 游戏Demo制作教程（3） 1.17

本文主要是介绍【不用找素材】ECS 游戏Demo制作教程（3） 1.17，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、生成墓碑

新建脚本如下：

using Unity.Entities;
using Unity.Mathematics;namespace ECSdemo
{public struct GraveyardRandom : IComponentData{public Random Value;}}

扩充GraveyardMono如下：

using Unity.Entities;
using Unity.Mathematics;
using UnityEngine;
using Random = Unity.Mathematics.Random;namespace ECSdemo
{public class GraveyardMono : MonoBehaviour{public float2 FieldDimensions;//float2 结构体表示一个包含两个 float 字段的结构体，记得引用命名空间public int NumberTombstonesToSpawn;//想要跟踪的数量public GameObject TombstonePrefab;//墓碑预制件public uint RandomSeed;}public class GraveyardBaker : Baker<GraveyardMono>{public override void Bake(GraveyardMono authoring){AddComponent(new GraveyardProperties{FieldDimensions = authoring.FieldDimensions,NumberTombstonesToSpawn = authoring.NumberTombstonesToSpawn,TombstonePrefab = GetEntity(authoring.TombstonePrefab)//GetEntity:把GameObject变成Entity});AddComponent(new GraveyardRandom{Value = Random.CreateFromIndex(authoring.RandomSeed)}) ;}}}

赋个值

这边也能看到了

再写个新脚本

using Unity.Entities;
using Unity.Transforms;namespace ECSdemo
{public readonly partial struct GraveyardAspect:IAspect{public readonly Entity Entity;private readonly TransformAspect transformAspect;private readonly RefRO<GraveyardProperties> _graveyardProperties;private readonly RefRW<GraveyardRandom> _graveyardRandom;}
}

二、生成僵尸

添加新脚本

using Unity.Burst;
using Unity.Entities;namespace ECSdemo
{[BurstCompile][UpdateInGroup(typeof(InitializationSystemGroup))]public partial struct SpawnTombstoneSystem : ISystem{[BurstCompile]void ISystem.OnCreate(ref SystemState state){}[BurstCompile]void ISystem.OnDestroy(ref SystemState state){}[BurstCompile]void ISystem.OnUpdate(ref SystemState state){state.Enabled = false;}}
}
