Use new vars

[JapaBijou]

Hi

I'm using pokefirered C decompilated code and I want to add some new vars usable in scripts

In var.h file, every var from 0x4000 to 0x40FF is already defined

How can I add a custom var? Can I change "VARS_END" (wich is set to 40FF) in order to use vars from 0x4100?

Thanks

Yeah, I think that's pretty much all there is to it.
You just add in new vars after 0x40FF following the lead of the previous ones, and adjust VARS_END accordingly.

Before adding in new vars, you should make use of all the unused vars the game has by default though, imo.
Vars that lack a proper label and are simply defined as "VAR_" followed by their internal ID are more often than not unused.
For a quick example, every var from VAR_0x408C to VAR_0x40A9 is unused.
A quick git grep will show that they're defined in the same file where the rest of the vars are, but without being actually used anywhere else in the code.
