Script Update!

Starting from version 1.1.0 you can now use or abuse of its brand new feature:   skill cooldowns!

NEW NOTE TAG:

Code:

<cooldown 1>
<cooldown 4>

If you want to clear the cooldowns ingame, use this:

Code:

$game_party.clear_skill_cooldowns!

Skill Updated Once Again!

In version 1.2.0 you can now change the color of the skill name and its SP cost at will!
At least while it is still cooling down.

Just go to the SkillColor module and edit its CD_COLORS hash.

This is how the module looks like in its default state:

Code:

module SkillColor
  CD_COLORS = {} # Leave this line alone!
  # CD_COLORS[TurnsMin..TurnsMax] = [Red, Green, Blue]
  # Example: CD_COLORS[1..1] = [255, 255, 255] # For a Single Turn
  CD_COLORS[1..2] = [255, 255, 0]
  CD_COLORS[3..4] = [255, 165, 0]
  CD_COLORS[5..8] = [255, 60, 0]
  CD_COLOR_KEYS = CD_COLORS.keys.sort{|a, b| a.min <=> b.min }.reverse
end

Game Development is ALL About Nerfing!

Well, this time I've come back to update the normal version and its colored counterpart.

 What new feature does it include now?

It now lets  cast a skill twice only!

Just leave this note in the skill's note box:

Code:

<cast_only_twice>

 Not really what you were expecting, is it?
 Who cares? Somebody else might need that brand new feature at some point.
