一、创建地形
1、gameobject ->3d object-> terrain，创建带有地形属性的平面
2、terrain-〉最后一个工具(terrain settings)->set resolution-〉setheightmap resolution ，把地形设置为500*500
3、调整视图
- hierarchy->camera，选择默认的摄像机
- hierarchy->camera->inspector->position->x=250,y=100,z=-250, game中能看到一个梯形状的平面(以后随时调整xyz值得到最佳效果)
4、设置地形高度
setheight
height->200
5、设置地形背景
二、应用资源包
1、下载资源
从unity官网中下载好所需要的资源包
“third person controller - basic locomotion free.unitypackage”
“environment pack free forest sample.unitypackage”
2、导入资源
assets->import package->custom package->依次选中package包
3、project ->all prefabs->将显示人像的thirdpersoncontroller_lite预制件拖拉到scene窗口中的地面上（参数可以选用默认值），同时将与thirdpersoncontroller_lite相隔3个的vthirdpersoncamera_lite预制件拖拉到scene窗口中(该预制件能跟踪人体的运动，替代默认的camera）。
4、选中hierarchy-〉untitled->main camera，在inspector下的main camera左边的小框中的勾选去掉，让main camera失效。
三、制作手雷
1、导入sceneshot.unitypackage
2、将grenade置入场景中
3、collisions.cs脚本程序(1) //拖拽到thirdpersoncontroller_lite上
using system.collections;
using system.collections.generic;
using unityengine;
public class collisions : monobehaviour
{
public static int grenade_ammo = 0;
// start is called before the first frame update
void start()
{
}
// update is called once per frame
void update()
{
raycasthit hit;
//check if we are collidering
float raycastlength = 5;
vector3 offset = new vector3(0,0.5f,0);
if (physics.raycast(transform.position+offset, transform.forward,out hit ,raycastlength ))
{
//...with a door
if (hit.collider.gameobject.tag == "door")
{
//open the door
hit.collider.gameobject.getcomponent<animation>().play("door-open");
}
}
debug.drawray(transform.position + offset, transform.forward, color.red);
}
void ontriggerenter(collider hit)
{
if (hit.gameobject.tag == "crategrenades")
{
debug.log("hit");
//destory the ammo box
destroy(hit.gameobject);
//add ammo to inventory
grenade_ammo += 200;
print("you now have " + grenade_ammo + " grenades");
}
}
}
4、shooting.cs脚本程序 //拖拽到thirdpersoncontroller_lite上
using system.collections;
using system.collections.generic;
using unityengine;
public class shooting : monobehaviour
{
// start is called before the first frame update
float speed = 3;
vector3 offset = new vector3(0, 1.0f, 0f);
[tooltip("gp")]
public gameobject grenadeprefab;
void start()
{
}
// update is called once per frame
void update()
{
screen.lockcursor = true;
//find out if a fire button is pressed
if (input.getmousebuttondown(0))
{
debug.log("shoot");
if (collisions.grenade_ammo > 0)
{
//create the prefab
gameobject grenade = instantiate(grenadeprefab, this.transform.localposition+ offset+ transform.forward, quaternion.identity);
//add force to the prefab
grenade.getcomponent<rigidbody>().addforce(transform.forward * 20, forcemode.impulse);
collisions.grenade_ammo--;
print("you now have " + collisions.grenade_ammo + " grenades");
}
}
}
}
5、grenadescript.cs脚本程序 //将脚本拖拽到grenade预制体上
using system;
using system.collections;
using system.collections.generic;
using unityengine;
public class grenadescript:monobehaviour
{
private float creationtime;
public gameobject explosionprefab;
int lifetime = 3;
// start is called before the first frame update
void start()
{
}
void awake()
{
debug.log("count");
creationtime = time.time;
}
// update is called once per frame
void update()
{
if (time.time > (creationtime + lifetime))
{
//destroy(this.gameobject);
instantiate(explosionprefab, transform.position, quaternion.identity);
}
}
}
6、在当前工程文件的assets目录下，建一个audio文件夹，将手榴弹爆炸音效文件grenade.mp3，拷贝到audio文件夹中
点击project->assets->audio->grenade音乐文件，在inspector面板最下方有一个运行按钮（右下方的grenade栏右边的箭头），可以倾听音效
project-〉prefabs-〉explosion- >在inspector中点击add component ->audio->audio source，在inspector中的audio source下有audioclip，
选grenade音乐组件单击hierarchy-〉vthirdpersoncamera_lite，查看inspector面板上的组件属性，audio listener起到在游戏运行时侦听场景中的音乐效果
运行，按键盘的左健，发射手榴弹，手榴弹落地后消失，在产生火焰爆炸特效的同时，可以侦听到手榴弹爆炸的声音特效
7、最终效果
