Crystal Noel · Nov 26, 2016

This script allows for the player to assign moves to be learned upon evolution as there is in Pokémon Sun and Moon.

To use, simply place this script above Main and below everything else.

# The 7th generation of Pokémon introduced the feature of evolution moves, a   #
# feature where a Pokémon would learn a move upon evolving reguardless of what #
# level it evolved at. The game defines these as being learned at level 0,     #
# which is not possible with the compiler, so they are defined here and upon   #
# evolving a species will check the list and learn the move. Do note that      #
# moves are not automatically added to the learn list, thus can't be relearned #
# through the move relearner, unless the move is also part of the Pokémon's    #
# learnset.                                                                    #

For people using this script, might want to double-check the Pokemon names. The Gen V mummy Pokemon gets part of its name censored, and it causes a syntax error.

EDIT: This is fixed by clicking "show printable version" in thread tools to the upper right

rigbycwts · Feb 25, 2017

There are some Pokemon who have a different move learned upon evolving if its form is an alternate form (e.g. Lycanroc). Perhaps this should be incorporated in some way.

zerokid · Aug 27, 2017

Sorry to necropost, but hopefully this will be useful to people who got here through Google.

I wanted the same features as rigbycwts and so I've made some edits to the original script, as well as corrected various errors that I found.

I added every move found here serebii.net/sunmoon/evolutionmoves.shtml, but I notice they made quite a few mistakes. There may be more than this, so let me know if you find any:

Kantonian Sandslash learns Crush Claw
Nuzleaf, not Lombre, learns Razor Leaf
Probopass learns Tri-Attack
Boldore, not Gigalith, learns Power Gem
Eelektrik, not Eelektross, learns Crunch

Alolan forms are considered to be form 1 here.

Note: as Rot8er_ConeX suggests, a certain Pokemon name is censored. This is fixed by clicking "show printable version" in thread tools to the upper right.

# evolving a species will check the list and learn the move. Do note that      #
