Hello,

After balancing the stats and working out the skills and talents for my rmxp game during the past couple of days, I am running into a bump.
For many of the skills my actors use, I want to have a cooldown function. Meaning they cannot use specific skills for X number of turns (I use the default battle system).

Example:
Skill 1 has no cooldown
Skill 2 has a cooldown of 3 turns
Skill 3 has a cooldown of 10 turns

Ideally these skills will be greyed-out when on cooldown.

I suppose this can be done with eventing, but I think it would be far more efficient with a script.
When I looked for one, I could not find anything for rmxp.

I am hoping someone can refer me to a working script or help me tweaking one to make it work in the way I'm looking for.

As mentioned, I do not use a custom battle system, but I do use some scripts that influence battle/skills which I'll post just in case:
Threat system by Fantasist, reflection by Blizzard, hots dots by Shdwlink1993.

You could try this script.
Sadly I don't know who made this anymore

Code:
   #==============================================================================

    module Config

      Cooldown = {} # Do not touch

      Cooldown[1] = 10 # Skill with ID 1 has a cooldown of 10 turns.

      alias cooldown_skill_can_use skill_can_use?

      def skill_can_use?(skill_id)

        return false if @cooldown[skill_id] != nil and @cooldown[skill_id] > 0

        return cooldown_skill_can_use(skill_id)

      end

      #--------------------------------------------------------------------------

      #

      #--------------------------------------------------------------------------

      def update_cooldowns

        @cooldown.keys.each {|id|

          @cooldown[id] = [@cooldown[id] - 1, 0].max if @cooldown[id] != nil

        }

      end

      #--------------------------------------------------------------------------

      #

      #--------------------------------------------------------------------------

      def cooldown_clear

        @cooldown.keys.each {|id| @cooldown[id] = 0}

      end

      #--------------------------------------------------------------------------

      #--------------------------------------------------------------------------

      alias cooldown_battle_end battle_end

      def battle_end(result)

        for actor in $game_party.actors

          actor.cooldown_clear

Thanks for the script!

But, when I tested, the skill was still available after the first turn.
When I used it again in turn 2, it became grey in turn 3 though.

Any idea why?

EDIT: it doesn't seem to be working at all now. I'm using a fresh project without scripts to test.

Hmm it works for me.
If I start a fresh project and give Aluxes' Cross Cut Skill a cooldown of 3 turns, it greys out once he uses the skill.

It might have been because I used a healing skill, I will try again tomorrow morning.

Hey, guys. That script is by Victor Sant. He wrote that back in 2011 when he was still known as Atoa.

Alright, I'll put his name in the script so I won't forget to credit him if I ever share it.

Also, it seems to be pretty glitchy with healing spells (I need to use a spell twice in a row to trigger the cooldown and it will be one turn less than supposed to).
Could it be that the script will have trouble with such skills because of their scope or occasion?

I figured out what the problem is.
Whenever a skill has a negative number or 0 as power value, the script won't work as intended.

Problem is, I mostly want to use cooldowns for utility skills (buffs, disabling abilities, etc.).
Meaning I can not use the script this way.

Anybody willing to help me fix this?

There's a part of the script that says "if effective"... Why don't you comment it out? That means placing a # pound symbol right in front of it... Check out if it now works as expected.

Thanks, that did the trick!
It works now, so long as a skill doesn't have scope "none", which is fine.

This should make the combat much more interesting, by having to use rotations and timing your "once in a battle" skills.
