Introduction
By default, RPG Maker MZ doesn't allow for dynamic changes to traits during gameplay, with the exception of the typical parameters. However, with this plugin, that is now a possibility for all traits!

This is a very simple plugin, with one feature - the ability to dynamically enable/disable/modify traits during gameplay.

Plugin Commands / Script Calls
Modify Trait
  • Class - The class whose trait you want to modify.
  • Trait - The trait that you want to modify, from the class's list of already assigned traits. This starts from 0, so Trait ID 0 would be the first trait in the list, Trait ID 1 would be the second, and so on. (The plugin cannot modify a trait which is not already on that list. If you wish to modify a 'new' trait, enter it initially with a value of e.g. zero or 100% depending on what the neutral figure is. An example of a new trait might be 5% Magic Reflect which the actor did not have before.)
  • Code - This is the number that determines what type of trait is being modified. Unless you're very familiar with the source code of RMMZ, I recommend that you just use the dropdown.
  • Data ID - Some of the traits prompt you to select from a dropdown menu. If this is one such trait, the Data ID is the index for that dropdown. This starts from 0, so Data ID 0 would be the first item in the dropdown, Data ID 1 would be the second, and so on. For example, Evasion Rate would be Data ID 1, Magic Reflect ID 5, and so on.
  • Modifier Type - Overwrite, Add, or Subtract. Overwrite will replace the existing value of the trait, Add will add to its existing value, and subtract will subtract from it. Add and Subtract will only work for traits which involve number inputs.
  • Value - Some of the traits prompt you to input a numerical value. If this is one such trait, the Value is the number you enter in that box (i.e. the number will be the new value, not the difference between the old value and the new). For percentages, this is a decimal value, but for everything else this is a whole number.
