Catch an ability level up

[DaneTheBeast]

Is there a way to know when a hero has leveled up an ability? (NOT when he first learns it)
If not, what are the best workarounds?

Perhaps you could use a periodic events that checks the current ability level, using a integer condition?

• Conditions
  • (Level of <Some Ability> for (<Some Hero>)) Equal to X

It looks like the best option is to use

• Unit - A unit Learns a skill

and then just check which level it is or just use it directly since it must be bigger than 0.

With the event Dane posted, there is the event response Learned Hero Skill. And when the event fires the skill has already been leveled up, so if it was being learned the first time its level will be 1, and it's being leveled up the first time (second click) it will be level 2+.

From common.j:

// EVENT_PLAYER_HERO_SKILL
// EVENT_UNIT_HERO_SKILL
constant native GetLearningUnit     takes nothing returns unit
constant native GetLearnedSkill     takes nothing returns integer // ability id
constant native GetLearnedSkillLevel takes nothing returns integer // new ability level

An alternative approach is to make your system recreate the state when levelling up rather than tracking deltas. This means that when you level from level 1 to level 2 you destroy the level 1 state and then create a level 2 state instead. This is useful as you can apply the logic directly if the ability level gets set, eg by trigger, instead of having to iterate through all levels up to the appropriate one.
