Hero Choosing - Choose a Hero with a "Choose" Ability

by .Ragnaros

Introduction

Very Easy 2/10

This tutorial consists in teaching you how to make a hero choosing system where the soul or the choosing unit has an custom ability called "Choose" or whatever you want, it doesn't need to be the same ability I'm using.

Here I'm gonna use a Banshee with a custom spell called Choose (I based myself in Storm Bolt ability and edited it in order to make the perfect "Choose" ability ^^)

The Triggers

• Choose the Hero
  • Events
    • Unit - A unit Finishes casting an ability
  • Conditions
    • Multiple ConditionsOr - Any (Conditions) are true
      • Conditions
        • (Unit-type of (Target unit of the ability being cast)) Equal to (==) Paladin
        • (Unit-type of (Target unit of the ability being cast)) Equal to (==) Blood Mage
        • (Unit-type of (TTarget unit of the ability being cast)) Equal to (==) Archmage
  • Actions
    • Unit - Create 1 (Unit-type of (Target unit of the ability being cast)) for (Owner of (Casting unit)) at (Center of Here <gen>) facing Default building facing (270.0) degrees

See below the explanation...

Triggers Explanation

*The Events*

On the First Trigger ("Choose the Hero") we've...

• Unit - A unit Finishes casting an ability

This event makes the actions run only when a unit finishes casting an ability checking conditions (conditions explained below)

*The Conditions*

• (Ability being cast) Equal to (==) Choose Hero
  • Multiple ConditionsOr - Any (Conditions) are true
    • Conditions
      • (Unit-type of (Target unit of the ability being cast)) Equal to (==) Paladin
      • (Unit-type of (Target unit of the ability being cast)) Equal to (==) Blood Mage
      • (Unit-type of (Target unit of the ability being cast)) Equal to (==) Archmage

Ok, here's one of the most important part of the trigger, without this, your chooser could just cast the "Hero Choose" on any unit randomly and it would provoke chaos! Now explaining each single condition:

• (Ability being cast) Equal to (==) Choose Hero

This condition makes sure that the event ability being cast is Choose Hero. If it is, it'll check the other condition:

• Multiple ConditionsOr - Any (Conditions) are true
  • Conditions
    • (Unit-type of (Target unit of the ability being cast)) Equal to (==) Paladin
    • (Unit-type of (Target unit of the ability being cast)) Equal to (==) Blood Mage
    • (Unit-type of (Target unit of the ability being cast)) Equal to (==) Archmage

This "OR" condition makes sure that the hero you targeted with the "Choose Hero" spell is Paladin, Blood Mage OR Archmage (You can customize it for your own heroes), if it wasn't an OR condition it would check if the targeted hero was Paladin, Blood Mage AND Archmage. Choosing the right condition type is very important, because it could screw up your map.

*The Action*

• Unit - Create 1 (Unit-type of (Target unit of the ability being cast)) for (Owner of (Casting unit)) at (Center of Here <gen>) facing Default building facing (270.0) degrees

If every condition fits the situation then this action will be ran, it creates an Hero of the same type of the hero you targeted with your "Choose Hero" in the middle of region "Here" (You can change the region "Here" to whatever you want).

Seems superfluous for such an easy task. Scope is extremely narrow. You use unit finishes cast when you should be using starts effect, and you leak a location when you create the unit.

 

[.Ragnaros]

Beep, Where's the leak? I mean... I'm not using variables, I create an unit directly in the center of the region...

The finish the effect of an ability means that the unit will do the ability animation before picking the hero, if It was begins the effect of an ability it would be instantly and without special effects.

 

[aznricepuff]

Center of Region creates a new location that needs to be destroyed.

 

[.Ragnaros]

Hmm I see... but what's the newly created location called? So I can use the call RemoveLocation

 

[aznricepuff]

It's not called anything. You would need to save it in a variable separately then use it, then destroy it.

 

[.Ragnaros]

Hmm I see... instead of moving it directly to the center of a determined region, first set a variable to that region, moving the unit to the variable and then destroying the variable, am I right?

 

[aznricepuff]

set the variable to the location (i.e. center of region).

 

[.Ragnaros]

Yep I see. I'll fix it when I have time. Thanks for reporting me and explaining how to fix the leak.

 

[M4stah]

Storm bolt is a bad abilty for these things due to it always stunning. Use channel for these things, its also more configurable and made for these things.

Also, instead of making a condition for every hero(Imagine if you have 50 heroes), just make a condition

• Conditions
• (Unit type of (Triggering unit) is not equal to Hero Chooser

 

[.Ragnaros]

Yep I see... but I'm 100% sure you wouldn't make like 50 heroes in 1 day, you would make like 1 hero then change to trigger editor and add a new condition for the brand new created hero, I guess. Checking if the targeted unit is a certain hero is more secure.

 

[Zack1996]

Perhaps it would be simpler if you just based the spell off the Banshee's Possess and allow hero targetting?
You can then simply use "Unit- Changes Owner" or whatever and move the unit to the place you want.

Not really a very useful tutorial IMO, but if you add different stuff, you could consider it a "Snippet" kind of tutorial, which includes different kinds of small systems and stuff.

Good luck with this tutorial, it's ok so far.

 

[.Ragnaros]

But the objective isn't to change the owner of the neutral targeted unit, the objective is to create an unit of the same type of the targeted unit...

 

[M4stah]

Also think about the speed. Whats faster, checking 50 things or 1?
Also, you haven't fixed the location leaks yet
