[soma_cruz20]

how do i create a spell with an hp requirement?
example: can only cast this spell when your hp falls below 40%

• (Percentage life of (Casting unit)) Less than or equal to 40.00

welcome to TH.net
-EDIT, yeah, the trigger in the post below works
or you can

• Untitled Trigger 001
  • 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
        • (Percentage life of (Casting unit)) Less than or equal to 40.00
      • Then - Actions
        • -------- your actions (if you have any triggered ones) --------
      • Else - Actions
        • Unit - Order (Casting unit) to Stop

but yeah, they are basically the same, and iv tested it, and it worked

• Ability
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Ability
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Percentage life of (Casting unit)) Greater than 40.00
      • Then - Actions
        • Unit - Order (Casting unit) to Stop
      • Else - Actions
        • -------- Else - Carry out the actions on another trigger with the event "A Unit Starts the effect of an ability" --------

the problem is that mana will still be affected if you use the ability when you're hp is above 40% is there a solution to this???

 

[keychup]

yes. look at my event: "a unit begins casting an ability"
That's when a unit attempts to cast a spell. I thought it would order your unit to stop before using mana.

You can't change spell mana cost using triggers, the only way is to set mana cost to zero in the ability and then do this

• Events
  • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Ability
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Percentage life of (Casting unit)) Greater than 40.00
      • Then - Actions
        • //Percentage life Greater "no spell casted but add mana cost"
        • Unit - Set mana to (Mana of (Casting unit) - the cost you want)
        • Unit - Order (Casting unit) to Stop
      • Else - Actions
        • //If you add set mana cost ability to zero, you dont have problems sing the ability in low mana mod
        • -------- Else - Carry out the actions on another trigger with the event "A Unit Starts the effect of an ability" --------

This is correct, it stops before cast.

Maybe you could consider showing a text message saying that the ability cannot be used if you have more than 40% of your HP remaining.

Sure, but that's a subject for another problem: more specifically "how can i make the ability look good".

It's called SimError by Vexorian, I believe.
It simulates the yellow text errors at the bottom of your screen.

You can simulate an error message saying "You're above 40% HP!" or something.
Also, this works fine, and doesn't use mana if the spell can't be cast:

• <YourTrigger>
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to <Ability>
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Percentage life of (Triggering unit)) Greater than or equal to 40.01
      • Then - Actions
        • Unit - Order (Triggering unit) to Stop
      • Else - Actions

You don't need anything under 'Else - Actions'.


If you find/want to use the SimError, it's just:

call SimError(GetTriggerPlayer(), "MESSAGE HERE")
