Leveled List Rare Drop ?

[hexef]

Hi.

 

I am trying to make a legendary weapon drop system like in Fallout 4 through leveled lists. The problem I encounter is that I don't know how to make my legendary weapon have a 5% drop chance. For example, let's say I have a legendary laser rifle with a 5% drop chance. I've created a new leveled list with the legendary laser rifle with chance none of 95 ( which means the legendary LR will have a 5% drop chance ).

 

The problem now is how can I make it so that if the game doesn't roll the legendary LR ( which is a 95 out of 100 chance ), the leveled list generates a normal vanilla LR ? A badly optimized solution is creating a leveled list containing 95 instances of the vanilla LR and 5 instances of the legendary LR, but this is very dirty and messy in terms of optimization.

 

Another solution is making 2 leveled lists. The first one contains only the legendary LR with a chance none of 95. The second one ( with chance none of 0 ) contains 2 elements: the vanilla LR and the first leveled list previously mentioned. So now if the game doesn't roll the 5% of the legendary LR, it will generate a vanilla LR. But there is another problem: if the game rolls the 5% chance of the legendary LR, then the game will also generate the vanilla LR, which means it will generate both of the weapons for the same NPC/container.

 

Any other solutions ? Thanks for the help.

I'd go for a fancy scripted solution which wouldn't use levelled lists but instead check an actor or container's weapons, roll a 5% chance in each to be legendary, then replace the items accordingly. Then again I'm me, so I would do that.

 

But no, your only simple option is to go for a levelled list with the 1 in 20 ratio in order to result in a 5% chance of a legendary. You'd also need to make a "Cond" levelled list for each legendary weapon, and use that when making the weighted list, so that they have varying condition when they spawn, too.

I'm almost certain I will go with the 1:20 ratio solution because it is easier to make. Also, thanks for mentioning this, I've forgot about fraction simplifications, lol. The reason I was thinking about making a list of 95 instances of common weapons and 5 of legendary was because I forgot about fraction simplifying... So a 5:95 ratio is equal to 1:19 ratio, which is much, much easier to implement. Thanks a lot for clearing this up for me.
