[Pokemon Red] Adding a trainer

Hello everyone,

I am very new to ASM so apologies in advance if this question is silly.

The pokered version I am working with: https://github.com/pret/pokered (downloaded on Dec 1st, 2020)

What I wanted to do: Add another OPP_LASS trainer on route 3.

Where I added to:

1. data\maps\objects\Route3.asm
2. data\trainers\parties.asm
3. scripts\Route3.asm
4. constants\event_constants.asm
5. text\Route3.asm

Successful Outcome:
-The additional lass is there (Screenshot)
-She battles me using the Pokemon I defined

Unexpected Outcome:
-She only fights me when I talk to her but she doesn't see me (i.e. doesn't walk up to me)
-After I fight her, I can talk to her again and the fight starts all over
-With other trainers, I now have the same problem, that I can fight them again and again

My ideas where the problem might be:
-In the TalkToTrainer script in home\trainers.asm

Also, if I repeat the 5 steps from the list above using an older version of pokered (11th of July 2020), it works and I don't see the unexpected problems. I compared scripts and macros between the two versions (and of course there are differences) but I couldn't pinpoint where the error is.

Any help would be appreciated :)

Hi, I've moved this over to Decomp & Disassembly Help! :)

Ok thank you :)

Hey, did you managed to find a solution to your problem? I was trying to add new trainer in my game (its a room with the 8 gym leaders, so you can rematch them as many times as you want) but i couldnt find any proper tutorial on this. And wasnt able to do it on my own
