Hi , I begin on RPG maker and I've got a problem with a thing : I create a special skill class called ultimates. One of this spell is a transformation. So I put buffs ( using base option of rpg maker mv ) and create a common event for some "cinematic" things ( I remove things like music from the code here because it's not the problem) . But when I try the skill, the character manage to transform but at the end of the battle he is still in his upgraded form. I want an automatic for this transformation and not doing all event in Troops for returning the hero to normal from. Can you help me ? Hero appearance : Héros,ssj(0),hero(0),ssj if: Script : $gameTroop.isAllDead() Hero appearance : Héros,hero(0),hero(0),hero end
