最紧看论坛大家都在聊游戏八卦段子和岛民们的爱恨情仇那我就来毁一波气氛吧 ———————————————————————————————————————————— 介个特效呢我用这个模型：（模型链接：https://box3.fun/v/124396）然后要做两条龙绕着一个球滚动的特效不说多了，直接上代码 constQuat=newBox3Quaternion(0,0,0,1);//初始旋转 world.onPress(({entity,button,raycast:{direction}/*懒得多写，demo好用*/})=>{//点击事件 if(button==='action0'){//不懂非人 constball=world.createEntity({ mesh:'mesh/火球.vb', position:entity.position, gravity:false, collides:false, fixed:true, }) constdragon_1=world.createEntity({ mesh:'mesh/黄金龙首.vb', gravity:false, collides:false, fixed:true, meshScale:[0.0625,0.0625,0.0625], }) constdragon_2=world.createEntity({ mesh:'mesh/黄金龙首.vb', gravity:false, collides:false, fixed:true, meshScale:[0.0625,0.0625,0.0625], }) constup=Math.atan2(direction.y,Math.sqrt(direction.x**2+direction.z**2));//仰角 constangle=Math.atan2(direction.z,direction.x); conststartTick=world.currentTick;//发射事件 dragon_1.lastPosition=dragon_2.lastPosition=newBox3Vector3(0,0,0);//不用管它，设几都一样 constdragons=[dragon_1,dragon_2];//冷光偷懒 constradius=3;//旋转半径 for(consteofdragons){//API玩家输入信息的demo Object.assign(e,{ particleRate:100, particleLifetime:20, particleSize:[8,6,4,2,0.5], particleColor:[ newBox3RGBColor(1,1,0), newBox3RGBColor(1,1,0), newBox3RGBColor(1,0,0), newBox3RGBColor(1,0,0), newBox3RGBColor(1,1,1), ] }) } constticker=world.onTick(()=>{//如果不能cancel就用clock.js（不是所有人都懂） if(world.currentTick-startTick>200){//超时销毁 ball.destroy(); dragon_1.destroy(); dragon_2.destroy(); ticker.cancel();//统统删掉=) } ball.velocity=dragon_1.velocity=dragon_2.velocity=direction.scale(3); //谁也不懂 dragon_1.position=ball.position.add({ x:Math.cos(angle+Math.PI*0.5)*Math.cos(up+world.currentTick*0.3)*radius, y:Math.sin(up+world.currentTick*0.3)*radius, z:Math.sin(angle+Math.PI*0.5)*Math.cos(up+world.currentTick*0.3)*radius, }) dragon_2.position=ball.position.add({ x:Math.cos(angle+Math.PI*0.5)*Math.cos(up+world.currentTick*0.3+Math.PI)*radius, y:Math.sin(up+world.currentTick*0.3+Math.PI)*radius, z:Math.sin(angle+Math.PI*0.5)*Math.cos(up+world.currentTick*0.3+Math.PI)*radius, }) for(consteofdragons){ constdirection=e.position.sub(e.lastPosition); e.meshOrientation=Quat.rotateY(Math.PI*0.5).rotateX(Math.atan2(direction.y,Math.sqrt(direction.x**2+direction.z**2))).rotateY(Math.atan2(direction.z,direction.x)); e.lastPosition.copy(e.position); } }) } }) 看着有些奇怪不过是俩条龙绕着一个球转就对了 GIF效果图要处理好久就懒得弄了）

排版、。。

牛啊牛啊

冷光，你能不能在2月三日时上武器试验场的空岛，让我们痛痛快快的打吉吉？求求了！imgsr喵demao.cn/emoji/codemao/%E7%BC%96%E7%A8%8B%E7%8C%AB_%E6%BA%9C%E4%BA%86%E6%BA%9C%E4%BA%86.gif"alt="emotion_编程猫_哀求"

我敢打赌冷光不会弄闪电⚡⚡⚡特效
