长按左键即可使用激光束，松开即结束喵

操作指南

步骤：首先放置一个名为"舰载激光炮"的模型，并添加标签"autogun".

其次，随处放一个模型并将其调整到一个合适的大小（这个大小决定了激光束的粗细），并添加标签"laser".

然后，添加以下代码：

const Quattt = new Box3Quaternion(0, 1, 0, 0);

world.onPress(({button,raycast:{hitPosition}}) => {
    if (button=='action0'){
        world.querySelectorAll(".autogun").forEach(async (e) => {
            var direction = hitPosition.sub(e.position);
            var orientation = Quattt.rotateY(Math.atan2(direction.z, direction.x));
            e.meshOrientation.copy(orientation);
            world.querySelectorAll(".laser").forEach((en)=>{
                en.meshInvisible=true;
                en.position.set(e.position.x,e.position.y+0.9,e.position.z);
                    en.particleLimit = 1000;
                    en.particleRate = 1000;
                    en.particleColor = [new Box3RGBColor(0.2, 0.2, 1), new Box3RGBColor(0.5, 0.5, 1)];
                    en.particleSize = [10, 8]
                    en.particleAcceleration.set(0, -5, 0);
                    en.particleVelocity.set(direction.x*8,direction.y*8,direction.z*8);
                    en.particleLifetime = 2;
            })
           
        })
        

    }

});
world.onRelease(({button})=>{
    if(button=='action0'){
        world.querySelectorAll(".laser").forEach((en)=>{
            en.particleLimit =0;
        })
    }
})

不能攻击？

求导弹代码

你家代码老了，在下改了一下

world.onPress(({button,raycast:{hitPosition}}) => {
    if (button=='action0'){
        world.querySelectorAll(".炮").forEach(async (e) => {
            var direction = hitPosition.sub(e.position);
            var orientation = Quattt.rotateY(Math.atan2(direction.z, direction.x));
            e.meshOrientation.copy(orientation);
            world.querySelectorAll(".激光").forEach((en)=>{
                en.meshInvisible=true;
                en.position.set(e.position.x,e.position.y+0.9,e.position.z);
                    en.particleLimit = 1000;
                    en.particleRate = 1000;
                    en.particleColor = [new Box3RGBColor(0.2, 0.2, 1), new Box3RGBColor(0.5, 0.5, 1)];

            })

    }
