我们都知道,7.1问答会上,J. ALLEN BRACK(暴雪副总裁)曝光了橙装掉落机制,现在,根据他的回答,小编简单计算了一下橙装的掉落机制,附上详细的计算过程,望大家早日出橙装;
先上懒人包:
1.只要肝的猛,橙装是必出的,没有脸黑不出橙装的事情。(后文有详细论证过程)
2.根据数据曲线,如果你每周必打一次普通翡翠、一次H翡翠,每天做完箱子任务,每天打2次以上大米,最多最多你将在第94天的时候出橙装,只可能小于这个值,不可能大于这个值(除非程序BUG);
3.每一次出橙装都会重置“脸黑指数”,重新开始循环(重新计数94天);
计算过程:
一、引入期望概念
这里要引入期望的概率,这个很好理解,假定我们每天出橙的概率一直是恒定的2%(实际上这个值在不断的变动,每一次没有出橙都会使这个值上升),我们每一次的拾取,出橙的概率是如何计算的呢?按照表一进行计算(表格见附录):
第一张表的计算是最简单的:公式:1-第一抽不中概率*第二抽不中概率……
第一张表的结论(横轴是天数,纵轴是几率):如果出橙概率恒定(假定值为0,04%,0.04%是游戏公司最常用的概率数值之一,因为分布较均匀,这里用这个做假设),出橙的比率为:
结论:正常情况下,如果没有防脸黑机制……
(1)我们玩游戏的第三十天(第一个月结束),我们出橙的概率只有可怜的11%
(2)我们玩游戏的第六十天(第二个月结束),我们出橙的概率只有可怜的21%
二、引入防脸黑概念
防脸黑概念其实非常简单,就是每一次摸橙,只要没有出橙,就会增加下一次摸橙的概率,简单的来说,每一次失败都会增加成功的几率,我们需要引入一个计算的表格,详见表二:
注:这里引入了假定,每次行为增加的概率都是一致的,但是实际情况并不是这样,因为根据行为的不同,增加的概率必然是不一样的,我们的几种典型活动为:
| 分类 |
| PT团本 |
| H团本 |
| 卡拉赞 |
| 10M |
| 世界任务箱子 |
| 大米 |
| 战场 |
| H本 |
| 采集/小怪 |
这几种活动一定有自己的增加概率对应表,这里简化计算,计算比例和为0.02%,按比例增加抽中概率(详见表三):
直接看图形:
可以直观的看到,防脸黑大大的增加了出橙装的概率,总结为:
(1)我们玩游戏的第三十天(第一个月结束),我们出橙的概率有52%
(2)我们玩游戏的第六十天(第二个月结束),我们出橙的概率有77%
概率上期望值破70%,已经可以视为必出了,第94天达到90%
