AOR concept: 199+ AOR with just 8 resources

[Kiliç Alì]

This tutorial explains only a concept that may be used when making AORs

In order to make an unit recruitable only in one (or another) settlement you put an hidden resource in it, and then you use the presence of the resource as a condition in EDB.

Now, the hardcoded limit for those resources is about 64, meaning "only" 64 AORs are avaiable, if you use all hidden_resources for this purpose. But hidden resources can be used also for others purposes, and waste them (at least, lot of them) in AORs is evil.
To bypass this limit, the hidden resource Power set must be used, meaning that with n resources, you can make up 2ⁿ AORs.
Example

Spoiler Alert, click show to read: 

with just 4 resources (A, B, C, D) you can make 16 differents AOR:
1 - nothing
2 - only A
3 - only B
4 - only C
5 - only D
6 - A & B
7 - A & C
8 - A & D
9 - B & C
10 - B & D
11 - C & D
12 - A, B & C
13 - A, B & D
14 - A, C & D
15 - B, C & D
16 - A, B, C & D

with just 9 hidden resources put in this way, you can make 512 AOR - far more than the EDU possibility, since hard-coded units limit is 500.
and, remembering hard-coded region limit is 199, you will need only 8 of them (256 AORs) - leaving the other 56 for other purposes.

Hope this to be useful

Hey bud, I think you meant to post this in the tutorials section

Indeed... please can an admin move this?

This is hardly unknown, its called binary encoding of the regions and has been used in RTW. The major drawback of course is that to identify a particular region takes 9 hidden resource conditions, hardly ideal for quick coding. The easier way to do it is to use ~29 hidden resources, which allows you identify a region uniquely with only 2 hidden resource conditions, much more ideal for ease of coding while still leaving plenty of hidden resources for other things. The basic concept is the same, split the map into 15 zones each of which has no more than 14 regions in it. Each zone has a corresponding hidden resource (15 HRs), also create 14 hidden resources to uniquely identify regions within each zone. Now each region in a zone gets the zone specific hidden resource and one of the 14 region specifying hidden resources. So a condition to uniquely specify a region would consist of the zone hidden resource and the region hidden resource.

Isn't it easier to do a combination?
10C4 gives you 210 possible combinations, no repetition, combinations with same numbers but different order are unaccounted. So you have all regions with a specific and unique set.

It's not useful when you are using it for large groups of regions. But it's the most easier to code (You always write 4 hidden region ids and you can do it like a binary count).

And with the one you posted, there's the problem that the sets 2,6,7,8,etc. contain A, but the first one only has one hidden region, so you have to check if it has A, and if it doesn't have B, C or D.
