get mana cost

[Chrome Stylus]

In a trigger I need a function to be able to return (in integer or real) the mana cost value of a spell. The spell being refered can be any spell (spell cast by casting unit). What do i do?

 

[Warlord_HU]

First make an dummy unit that has the spell.

• Warlords trigger
  • Events
    • Time - Elapsed game time is 0.01 seconds
  • Conditions
  • Actions
    • Unit - Set mana of Dummy unit <gen> to 100.00%
    • Unit - Order Dummy unit to Your spell
    • Wait Xcasting timeX seconds
    • Set Mana_cost = ((Integer((Max mana of Dummy unit))) - (Integer((Dummy unit))))
    • Unit - Set mana of Dummy unit to 100.00%

If you still don`t know what to do just ask.

(Mana_cost is an integer)

I'm a little confused, you want the mana cost of a spell to be 0, virtually?

 

[Warlord_HU]

And i would recommend to use this

• Warlords trigger
  • Events
    • Time - Elapsed game time is 0.00 seconds
  • Conditions
  • Actions
    • Unit Group - Pick every unit in (Units of type Dummy unit) and do (Actions)
      • Loop - Actions
        • Animation - Change (Picked unit)'s vertex coloring to (100.00%, 100.00%, 100.00%) with 100.00% transparency

trigger,

and add to your dummy unit locust.

The first post answered my question, i was planning on doing it that way, I just wanted to know if there was a function for Integer values to find the exact cost of a spell without going through all of that; also making a dummy unit will force me to retool how the mechanic works for this particular spell

ask in the JASS section, the JASS maker had probably already done this function (because your sure not the first one who need this)

Warlord's first post is (one of) the best ways to do that. Ideally, you would use a gamecache with all of the mana costs stored in it, but for GUI, the above suffices. There's no magic JASS function to get mana cost

Another way to do it, though, would be to set one of the ability's fields that it doesn't use (eg: Art - Area of Effect) to its value (eg "100") (must be an art field), then retrieve that value with GetAbilityEffect and I2S. However, this isn't a GUI thing, so if you don't want to muddle with JASS then Warlord's way is ideal.

 

[YoshiRyu]

doesn't JASS allow user to read each object field?

 

[PurplePoot]

Nope, only art fields <as I said>

I'll post the natives some time, if you want them.

 

[YoshiRyu]

That's a swindling!
pay me back! pay me back! pay me back!
...
oh sorry, i don't use JASS in fact

 

[Mechanical Man]

So you can access some fields from object editor? Excellent!

 

[YoshiRyu]

You can't access all fields! that stingy
does JASS allow recursivity?
