上期我们讲了如何做出鸡块旋转的效果

链接：https://shequ.codemao.cn/wiki/forum/530959

但是生成出来的鸡块并不能像MC里的掉落物一样可拾取

这期我就来教大家

如何做出像MC一样的拾取物品

 

这期代码需配合上期代码使用

附上上期代码：

var velocity=7
var velocity2=16
function spawn(x,y,z) {
    const e = world.createEntity({
        mesh: 'mesh/只因块.vb',
        collides: true, 
        friction: 0, 
        scale: new Box3Vector3(2, 2, 2),
        position: [x,y+1,z],
    });
    setInterval(() => {
        e.meshOrientation.copy(e.meshOrientation.rotateY(Math.PI / 180))
    }, velocity)
    const startPos = [e.position.x, e.position.y + 0.3, e.position.z]
    const endPos = [e.position.x, e.position.y, e.position.z]

    const ani = e.animate([
        { position: startPos, duration: 1 },
        { position: endPos, duration: 1 },
    ], {
        duration: velocity2 * 2, 
        iterations: 1,
        direction: Box3AnimationDirection.WRAP,
    })
    ani.play({
        duration: velocity2 * 2, 
        iterations: Infinity,
        direction: Box3AnimationDirection.WRAP,
    })
}
spawn(喵,8,喵 )

我这个方法可能会有一点点卡（真的就一点点，没喵），如果你的地图本身就很卡，有好多onTick那不建议使用

给经验添加标签

var velocity=7
var velocity2=16
function spawn(x,y,z) {
    const e = world.createEntity({
        mesh: 'mesh/只因块.vb',
        collides: true, 
        friction: 0, 
        scale: new Box3Vector3(2, 2, 2),
        position: [x,y+1,z],
    });
    e.addTag('jk')
    setInterval(() => {
        e.meshOrientation.copy(e.meshOrientation.rotateY(Math.PI / 180))
    }, velocity)
    const startPos = [e.position.x, e.position.y + 0.3, e.position.z]
    const endPos = [e.position.x, e.position.y, e.position.z]

    const ani = e.animate([
        { position: startPos, duration: 1 },
        { position: endPos, duration: 1 },
    ], {
        duration: velocity2 * 2, 
        iterations: 1,
        direction: Box3AnimationDirection.WRAP,
    })
    ani.play({
        duration: velocity2 * 2, 
        iterations: Infinity,
        direction: Box3AnimationDirection.WRAP,
    })
}
spawn(喵,8,喵 )

再定个循环）

setInterval(() => {
    
},100)

不停判断所有玩家位置

setInterval(() => {
    world.querySelectorAll('player').forEach(async (entity) => {
        world.querySelectorAll('.jk').forEach(async (e) => {
            if(Math.floor(entity.position.y)==Math.floor(e.position.y)){//如果鸡块和玩家在一层，也就是y坐标相等，那么执行以下代码
                if(Math.floor(entity.position.x)==Math.floor(e.position.x)){//如果x坐标差不多
                    if(Math.floor(entity.position.z)==Math.floor(e.position.z)){//如果z坐标也差不多
                    }
                }
            }
        })
    })
},100)

最后给玩家提示就行啦

setInterval(() => {
    world.querySelectorAll('player').forEach(async (entity) => {
        world.querySelectorAll('.jk').forEach(async (e) => {
            if(Math.floor(entity.position.y)==Math.floor(e.position.y)){//如果鸡块和玩家在一层，也就是y坐标相等，那么执行以下代码
                if(Math.floor(entity.position.x)==Math.floor(e.position.x)){//如果x坐标差不多
                    if(Math.floor(entity.position.z)==Math.floor(e.position.z)){//如果z坐标也差不多
                        e.destroy()//消除鸡块
                        entity.player.directMessage('你获得了一个鸡块')//提示玩家
                    }
                }
            }
        })
    })
},100)

全部代码：

var velocity=7
var velocity2=16
function spawn(x,y,z) {
    const e = world.createEntity({
        mesh: 'mesh/只因块.vb',
        collides: true, 
        friction: 0, 
        scale: new Box3Vector3(2, 2, 2),
        position: [x,y+1,z],
    });
    e.addTag('jk')
    setInterval(() => {
        e.meshOrientation.copy(e.meshOrientation.rotateY(Math.PI / 180))
    }, velocity)
    const startPos = [e.position.x, e.position.y + 0.3, e.position.z]
    const endPos = [e.position.x, e.position.y, e.position.z]

    const ani = e.animate([
        { position: startPos, duration: 1 },
        { position: endPos, duration: 1 },
    ], {
        duration: velocity2 * 2, 
        iterations: 1,
        direction: Box3AnimationDirection.WRAP,
    })
    ani.play({
        duration: velocity2 * 2, 
        iterations: Infinity,
        direction: Box3AnimationDirection.WRAP,
    })
}
spawn(喵,8,喵 )
setInterval(() => {
    world.querySelectorAll('player').forEach(async (entity) => {
        world.querySelectorAll('.jk').forEach(async (e) => {
            if(Math.floor(entity.position.y)==Math.floor(e.position.y)){
                if(Math.floor(entity.position.x)==Math.floor(e.position.x)){
                    if(Math.floor(entity.position.z)==Math.floor(e.position.z)){
                        e.destroy()
                        entity.player.directMessage('你获得了一个鸡块')
                    }
                }
            }
        })
    })
},100)
