首先大家应该都知道视角这个《东西》，那么今天我们就讲讲视角的所有的代码  * 1.第一视角(这个很简单并且API都有就不再讲述)

world.onPlayerJoin(({entity})=>{
entity.player.cameraMode = Box3CameraMode.FPS;
})

 * 2.第三视角(这个很简单并且API都有就不再讲述)

world.onPlayerJoin(({entity})=>{
entity.player.cameraMode = Box3CameraMode.FOLLOW;
})

* 3.隐藏API:2D视角(横面)

world.onPlayerJoin(async function({entity}){        
        entity.player.cameraMode=Box3CameraMode.RELATIVE;
        entity.player.cameraPosition=new Box3Vector3(-0.01,40,0);
        entity.player.swapInputDirection=true;
        entity.player.reverseInputDirection=Box3InputDirection.HORIZONTAL;
        entity.player.cameraFreezedAxis=Box3CameraFreezedAxis.Y;
        entity.player.freezedForwardDirection=new Box3Vector3(0,0,1);
});

效果图：

 * 4.隐藏API:2D视角(竖面)

world.onPlayerJoin(async({ entity })=> {
    //设置视角
    entity.player.cameraMode = "relative"
    entity.player.cameraTarget.y = 1
    entity.player.cameraPosition.set(0, 0, -15)//3个数随便调，假设是a1,a2,a3，那么这一行的意思就是指从x+a1,y+a2,z+a3的地方看你（）
    //禁用WS
    entity.player.disableInputDirection = Box3InputDirection.VERTICAL;//这东西是禁止ws的
    entity.player.swapInputDirection = true//把这一行注释了后就可以搞事情了（？）
    //防止移动出错
    entity.player.freezedForwardDirection = new Box3Vector3(1, 0, 0);
    entity.collides.boolean = false
})

效果图：

 * 5.视角的缩放

world.onPlayerJoin(async({ entity })=> {
    entity.player.cameraFovY += 0.25;
})

 * 相信大家用了第4，5的代码后再切换第一视角，第三视角会出现锁视角的《特性》，所以：  * 6.解除锁视角

entity.player.swapInputDirection = false;
entity.player.freezedForwardDirection = null
entity.player.reverseInputDirection = Box3InputDirection.NONE

 * 下面就是神奇的fixed的用法  * 首先我先讲解一下fixed与4，5的区别哈  * 他与4，5的区别就是：4，5能够随着玩家的移动垂直于玩家的锁视角也随之移动，而fixed就有所不同，fixed是不随着玩家的移动而移动  * 那么我们知道区别了就开始fixed的用法  * (1)与4，5近似(2D) 首先我先讲一个 entity.player.cameraPosition，entity.player.cameraTarget的作用哈 entity.player.cameraPosition 是固定视角(FIXED)下，镜头的眼睛位置，entity.player.cameraTarget是固定视角(FIXED)下镜头所朝向的目标点，当然还有 cameraUp，cameraUp是固定视角(FIXED)下，镜头向上的矢量

world.onPlayerJoin(({entity})=>{
    entity.player.cameraMode=Box3CameraMode.FIXED;
    entity.player.cameraPosition = new Box3Vector3(44, 0, 144)
    entity.player.cameraTarget = new Box3Vector3(44, 0, 144)
    
})

数值的话大家自己调吧(作者懒)

* (2)《大片》视角的移动(重重之重)

world.onPlayerJoin(async function({entity}){       
                entity.player.directMessage('看完后自动关闭')
                entity.player.enableAction0 = false;
                entity.player.enableAction1 = false;
                entity.player.cameraMode = Box3CameraMode.FIXED;
                entity.player.animate([
                    { cameraPosition: new Box3Vector3(-22, 128, -22), cameraTarget: new Box3Vector3(-22, 20, -22), duration: 1 },
                    { cameraPosition: new Box3Vector3(150, 128, 150), cameraTarget: new Box3Vector3(0, 20, 0), duration: 1 },
                    { cameraPosition: new Box3Vector3(30, 128, 150), cameraTarget: new Box3Vector3(128, 20, 0), duration: 1 },
                    { cameraPosition: new Box3Vector3(30, 30, 150), cameraTarget: new Box3Vector3(128, 20, 0), duration: 1 },
                    { cameraPosition: new Box3Vector3(150, 30, 150), cameraTarget: new Box3Vector3(0, 20, 0), duration: 1 },
                    { cameraPosition: new Box3Vector3(150, 30, -22), cameraTarget: new Box3Vector3(0, 20, 128), duration: 1 },
                    { cameraPosition: new Box3Vector3(-22, 30, -22), cameraTarget: new Box3Vector3(128, 20, 128), duration: 1 },
                    { cameraPosition: new Box3Vector3(150, 128, 150), cameraTarget: new Box3Vector3(0, 20, 0), duration: 1 },
                    { cameraPosition: new Box3Vector3(172, 59, 209), cameraTarget: new Box3Vector3(28, 50, 150), duration: 1 },
                    { cameraPosition: new Box3Vector3(entity.position.x, entity.position.y + 1, entity.position.z), cameraTarget: new Box3Vector3(entity.position.x, entity.position.y, entity.position.z), duration: 1 },
                ], {
                    iterations: 1,
                    duration: 16 * 50,
                })
                await sleep(50 * 1000)
                entity.player.cameraMode = Box3CameraMode.FOLLOW;
                entity.player.enableAction0 = true;
                entity.player.enableAction1 = true;
})

好了，这一期的视角的应用就到此为止了

在最后我想问大家，你学废了么
