多个预制体的时候，随机生成某个预制体

Creator 2.x
#1

小白求助，我有多个预制体的时候，怎么随机生成某个预制物体

#2

如果是放在resource里的，建个文件夹，预制体全部命名成prefab1，prefab2这样，那你随机一个数然后拼接一下去加载预制体不就号了

const { ccclass, property } = cc._decorator;

@ccclass
export default class RandomInstance extends cc.Component {

@property(cc.Prefab)
allPre = [];

@property(cc.Node)
allPreFa;


Probability = 0.5;

onLoad() {

}

start() {
    this.onRandomInstanPre()
}

onRandomInstanPre() {
    let self = this;
    let allGl = this.allPre.length;//总共有多少个
    if (allGl < 1) return;
    //赋值每个概率范围
    let current = [,];
    let currentNum = 0;
    for (let i = 0; i < allGl; i++) {
        current[i] = [currentNum, (currentNum += (100 / allGl))];
    }
    cc.log(current, '-所有概率');
    for (let i = 0; i < 10; i++) {
        let num = Math.random() * (101 - 1)// + 1
        cc.log('随机数：',num)
        for (let j = 0; j < current.length; j++) {
            if(num >= current[j][0] && num <current[j][1]){
                //在这个范围内
                //cc.log(current[j],'用的第几组数据');
                let tNode:cc.Node = cc.instantiate(self.allPre[j])
                tNode.parent = self.allPreFa;
                continue;
            }

        }
    }
}
// update (dt) {}

}

代码不是很会写，请问有例子吗？

你好，有js版的吗？
