So if I'm understanding it correctly you want the Pokédex of the female character have a different looking Pokédex than the male character.
If that's the case do the following:
1. You
select a graphic you want to replace.
2. You
create the graphics you want to use(or placeholders) and put them into the same folder as the original
3. You
go to the script you wanna change (i.e. PScreen_PokedexMenu)
4. You
crtl + f and search for the
name of the graphic. Whenever there is line mentioning that graphic as a string(there are Quotationmarks before and behind the path) you
copy that path. Remember every
path is represented by a string which has
Quotationmarks before and behind it!
5.
One line above the one you just copied the path from you
insert the following code:
path = what you copied before comes here
if $Trainer.gender == 0 #male
path = put your male pic path here
elsif $Trainer.gender == 1 #female
path = put you female pic path in here
end
you could also do stuff like $Trainer.trainertype which will give the number from the pbs file or other stuff that is listed here:
Essentials Docs Player Character entry
6. You
replace the path in the original line including the Quotationmarks with
7.
Repeat step 4-6 until you replaced all the paths in that script.
The Pokédex has 3 scripts so you might want to look in all 3 of them (they are right below each other).
I'm not sure how it works with ruby if you could just go like:
$Trainer.gender == 0 ? "path1" : "path2"
which would make this entire thing so much shorter and more
Btw:
I haven't tested this out ... if I mistyped or the essentials docs aren't up to date there will probably be errors.
