Hello guys, I am new to RMXP and I am trying to create my own game, even if I don't know anything about RGSS. I have been trying for hours to create a script that will change a pokemon form during battle if it reaches half of the hp, and then after changing form it will be healed full. Someone advice me to work on the script of Darmanitan and Wishiwashi: I tried but I only got errors. Can you pease explain me how to write a script like this? I'll write down here the sequence:

1 - If the PKMN reaches half of the total hp, it will trigger the transformation

2 - Pokemon transforms

3 - Pokemon gets fully healed, only one time per battle
