CocosCreator中，生成连续整数数组、打乱数组、生成指定

    // 生成一个连续的整数数组(开始值，长度)
    private createSuccessiveIntArray(beginValue: number, length: number): number[]
    { 
        let array = new Array<number>();
        for (let i = 0; i < length; i++)
        { 
            array.push(beginValue + i);
        }
        return array;
    }
    // 打乱一个数组
    private shuffleArray<T>(currentArray: T[]): T[]
    { 
        // 从数组的最后一个序号开始，依次往前设置各序号对应的值
        let maxIndex:number = currentArray.length - 1;

        while (maxIndex > 0)
        {
            // 随机选得一个序号（已设置过值的序号不再参与抽取）
            const curIndex = randomRangeInt(0, maxIndex);
            // 当前选得的随机值
            const temp:T = currentArray[curIndex];
            // 将要设置值的序号的原值暂存起来
            currentArray[curIndex] = currentArray[maxIndex];
            // 设置当前目标序号的值为随机选得的值
            currentArray[maxIndex] = temp;
            maxIndex--;
        }
        return currentArray;
    }

    // 将原始数组生成指定长度的新数组
    private adjustArrayLength<T>(originalArray: T[], targetLength: number, shouldShuffle :boolean = true): T[]
    { 
        const singleLength = originalArray.length;
        const repeatCnt = Math.floor(targetLength / singleLength);
        const remainCnt = targetLength % singleLength;

        let retArray = new Array<T>();

        for (let i = 0; i < repeatCnt; i++)
        { 
            let curArray = originalArray.slice();
            if (shouldShuffle)
            { 
                curArray = this.shuffleArray(curArray);
            }
            retArray = retArray.concat(curArray);
        }

        let curArray = originalArray.slice();
        if (shouldShuffle) {
            curArray = this.shuffleArray(curArray);
        }
        for (let i = 0; i < remainCnt; i++)
        { 
            retArray.push(curArray[i]);
        }
        return retArray;
    }
