[Spell] Certain conditions make a spell usable

[Veritas 117]

I searched for an answer to this but couldn't find one

Basically I am wondering if there is a way to make an ability that shows up as disabled until a units health gets below a certain point. The spell I want to make is one where it becomes active once the heroes health is below 25% and then deals damage to nearby units equal to the difference between the max life of the hero and the current life while increasing armor and healing over time.

The only problem is that I don't know how to prevent the ability from being used until the Heroes health is below 25%. Any thoughts?

 if GetUnitLifePercent(yourunit) == 25 then

 if GetUnitLifePercent(yourunit) == 25 then

I know how to use a life percentage as a condition, but I don't know how to make an ability not usable until the condition is met

Use a DDS to find out when the hero takes damage. If health below 25%, do your actions. I recommend Bribe's Damage Engine

Its the actions that is the problem. I can make the ability do what I want with triggers I just want the ability to be inactive as if I didn't have enough mana except instead of checking the mana it would check to see if my health was low enough before becoming clickable.

Here is one that may help

• Untitled Trigger 002
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to <Your ability>
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (% Life of (Triggering unit)) Greater than 25.00
      • Then - Actions
        • Unit - Pause (Triggering unit)
        • Unit - Order (Triggering unit) to Stop
        • Unit - Unpause (Triggering unit)
        • Game - Display Message "Cannot use ability until HP is lower than 25%"
      • Else - Actions
        • Your ability code

Afaik there is no way to disable an ability as if the unit has no mana or is silenced.

However you can utilize Engineering Upgrade to replace a dummy ability with the real one when the unit's HP becomes lower than 25%.

 

[gorillabull]

just trigger the whole thing thats why the language exists ANOTHER option is to have one dummy ability and when the units health drops add your ability by replacing the dummy

Try this.

I made it so that you can not level the ability when under 25% hp.

only 1 trick exist for this what look cool and dont need dummy ability add/remove what screw up the spellbook opening, just a dummy unit....

make ability unit depend (techtree requiment a dummy unit with "25% hp" name)
check ur unit hp when going lower than 25% and create a dummy unit for player if dont exist already one, when ur hp going higher then remove the unit and null the variable

dummy unit must be with: no attack, no model file, non visiable in minimap, non movespeed, with locust ability, flying movement, 0 food cost. - this need onyl for make unable too cast the ability and if u check the ability then u can see with yellow letters the unit name (what could be anything like "low hp requiment" or what u want)
