Abilities System​By Paramecium13​ This is a simple script that adds 'abilities' to actors. An ability can be either leveled or not leveled. A leveled ability has a number, its level associated with it (e.g. Smithing: Level 27), whereas an ability that is not leveled does not.

Abilities System​
By Paramecium13​

This is a simple script that adds 'abilities' to actors. An ability can be either leveled or not leveled. A leveled ability has a number, its level associated with it (e.g. Smithing: Level 27), whereas an ability that is not leveled does not. This script has a section where you can add more abilities, using the same format as the example abilities. Abilities must be viewed and modified by script calls, using the methods contained in the script.

Features:

  • Add and remove abilities
  • Enable or disable abilities(this is different than adding or removing, for example, if someone who knows smithing has a broken arm they cannot smith, thus smiting would be disabled, but they could still tell someone how to smith or read about how to smith better),
  • Check if an actor has a specific ability and if it is enabled
  • Get the level of a leveled ability (using this on an ability that is not leveled returns '1')
  • Increase or decrease the level of an ability
  • Check if any actor in the party has an ability
  • Find who has the highest level of an ability in the party and what that level is.
  • Perform an ability check, using a normal distribution, for actors and for parties
  • Perform a simple ability check, which checks if the ability level is at least the difficulty level, for actors and parties
  • Weapons, armors, and states can modify ability levels, by putting <AbilityBonus: abilityId,n> into the notes field in the data base. 'abilityId' should be the ID of the ability you want to affect without a colon in front of it (e.g. 'smithing' instead of ':smithing') and 'n' should be the amount you want to change the ability by.
  • A very simple (i.e. ugly) scene that shows abilities and their levels; accessed from the main menu
  • Crafting abilities, which can be use to craft items.  Crafting abilities can start off with recipes already learned (but which may require a higher ability level) and can have additional recipes added by script calls.
This script requires my core script.

Features Mentioned

  • Add and remove abilities
  • Enable or disable abilities(this is different than adding or removing, for example, if someone who knows smithing has a broken arm they cannot smith, thus smiting would be disabled, but they could still tell someone how to smith or read about how to smith better),
  • Check if an actor has a specific ability and if it is enabled
  • Get the level of a leveled ability (using this on an ability that is not leveled returns &#039;1&#039;)
  • Increase or decrease the level of an ability
  • Check if any actor in the party has an ability
  • Find who has the highest level of an ability in the party and what that level is.
  • Perform an ability check, using a normal distribution, for actors and for parties
  • Perform a simple ability check, which checks if the ability level is at least the difficulty level, for actors and parties
  • Weapons, armors, and states can modify ability levels, by putting  into the notes field in the data base. &#039;abilityId&#039; should be the ID of the ability you want to affect without a colon in front of it (e.g. 'smithing' instead of ':smithing') and 'n' should be the amount you want to change the ability by.
  • A very simple (i.e. ugly) scene that shows abilities and their levels; accessed from the main menu
  • Crafting abilities, which can be use to craft items.  Crafting abilities can start off with recipes already learned (but which may require a higher ability level) and can have additional recipes added by script calls.
  • This script requires my core script.
