在前面的阶段实现了：3D地图、2D地图、视角控制、创建炮塔、创建怪物、怪物移动、怪物连续刷新等功能。下面也是最后的一个阶段：炮塔攻击、怪物死亡、信息展示这3个方面的介绍。

今天来介绍3D炮塔能攻击了：

修改原“TurretMesh.ais”脚本

LoadImage("TurretImg",":/Wooyoo/tower/turret01.jpg");  //炮塔纹理
//炮塔模型
LoadModel("TurretA1model",":/Wooyoo/tower/flame_thrower_01.obj","obj");
//炮弹模型
BulletA=IncludeAisx(":/Wooyoo/window7/ROCKETMOUNT3.aisx");
BulletA.action="WALK";//炮弹动画
BulletA.Scale={,,};//缩放炮弹模型
//炮塔模型数据
TurretBaseMesh=   
{
    type:"mesh";   //类型  mesh
    model:"TurretA1model"; //模型为炮塔A
    texture:"TurretImg";   //模型的纹理
    SimplerState:"wrap";   
    Shader:"phong";
    Scale:{,,};   //缩放下模型大小
    leftName:"";           //存储左炮弹名称

    x:;
    y:;

    OldXZ:{};  //保存炮弹的初始XZ坐标 
    //isloaded为创建后执行一次的事件，这里为创建左右炮弹

        PX1=-;  //左炮弹X平移
