No damage

[pride2518]

I want to make it so that the unit type Exterminator can't damage any unit type other than fiend, but I can't seem to get it right.

Here's my trigger...

• RestrictExterminator
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Unit-type of (Attacking unit)) Equal to Exterminator
    • (Unit-type of (Attacked unit)) Not equal to Fiend
  • Actions
    • Unit - Set life of (Attacked unit) to ((Life of (Attacked unit)) + (Damage taken))

The problem is that "Unit is Attacked" fires the trigger before damage is dealt.

Try using "A Unit takes damage" instead. (And yes, you're going to have to add the event manually to the trigger for every exterminator that enters the map.)

I suggest getting the GUI Friendly Damage Detection under the Systems, Triggers, and Demo Maps section.

The thing is, that trigger won't work because a unit can be attacked, but that doesn't necessarily mean that he took damage.

Actually the problem is that there's no "Damage taken" in this trigger.

You don't need a GDD (Damage detection system) for this. It's actually better to use unit - a unit is attacked. If you use GDD to detect damage and heal the damage, fatal attacks will still be fatal.

Pride2518:

Easy solution is this. Use the same trigger except for the actions, use this instead:

Unit - Pause (attacking unit)
Unit - Order (attacking unit) to Stop
Unit - Unpause (attacking unit)

 

[Tyman2007]

I never said you needed GDD, I just suggested it.

The problem with your trigger moridin is that if you interrupt the attack, the cooldown has not been set, so he is free to attack directly after being unpaused. If it's a chance that there will be no damage, then that damage that is fatal will just have to be fatal. There is no way beyond that except to create a new unit or find some sort of ability, but it's just how it is.

WC3's current capabilities are limited. Let's just wait for starcraft and see what it has to offer shall we?

I didn't get that :S. Could you explain what you mean by cooldown? :S

Are you using your Suicidal classification? If not, you can use an ability like Demolish and make the ability completely reduce the damage caused (0.01) and able to target only non-suicidal units, then add the suicidal classification to your other unit. Update: Check out this post.

 

[Moridin]

Alternatively, you could prevent the damage caused with a GDD event using the same trigger structure as your example.

I still don't understand why everyone is suggesting GDD..? He doesn't want the attack to happen in the first place, so won't it be better to detect the attack instead of the damage? If you detect the damage then fatal attacks won't be healed....

Really confused about this.

i would say go with bogrims solution but slightly different. use critical strike with negative damage multiplier (damage will be set to 0.00 then) and 100% hit chance. hide this ability in an invisible spellbook, and make it target only "sapper" or "ancient" units. now you just have to add the classification "sapper" or "Ancient" to all your "fiend" units.

Maybe you should expand on my first suggestion and make the unit only able to attack suicidal units.

"A unit is attacked" doesn't detect the attack. The event should be called, "A unit is target by an attack swing" because that's what the event really does. If you stop a unit that's about to swing, it will just swing again and result in a never-ending loop that will crash the game.

I understand what "A unit is attacked" does . I didn't know this infinite loop thing though. Gonna test it out and see...I thought if you paused the unit it worked :S.

Easy solution is this.
Unit - Pause (attacking unit)
Unit - Order (attacking unit) to Stop
Unit - Unpause (attacking unit)

Easier solution

Unit - Order (attacking unit) to Stop

 

[Moridin]

Easy solution is this. Use the same trigger except for the actions, use this instead:

Unit - Pause (attacking unit)
Unit - Order (attacking unit) to Stop
Unit - Unpause (attacking unit)

Tested. My solution works flawlessly . You don't need GDD .
I used this trigger:

• Attack Stop
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to Peasant
    • (Unit-type of (Attacking unit)) Equal to Paladin
  • Actions
    • Unit - Pause (Attacking unit)
    • Unit - Order (Attacking unit) to Stop
    • Unit - Unpause (Attacking unit)

...and my Paladin could attack a footman and a knight but couldn't touch enemy peasants. No half-swing or anything, he just wouldn't attack when the target was a peasant. The solution worked for an attack order, a smart order and no order (where the paladin auto-attacked nearby peasants, he would run upto them but not attack).
Edit: I still don't get what you meant by the infinite loop thing bogrim :S.

 

[Accname]

you dont need to pause the unit.

 

[Moridin]

you dont need to pause the unit.

You might be right. I didn't test it without the pause. I faintly remember something bugging if you don't do the pause, but that might be false memory or outdated information. It's easy enough to change anyway .

Edit: I still don't get what you meant by the infinite loop thing bogrim :S.

Two units stand next to each other, enemy to each other. One unit makes a swing. It's ordered to stop. It stops. It then re-assumes its normal AI behavior, and begins to attack again. It's ordered to stop again, and it goes on infinitely.

The AI isn't going to register the trigger when it chooses an attack target, and each time you order the unit to stop with a trigger you interrupt whichever orders the unit currently has. That makes the unit both hard and annoying to control.

I tested out the solution I posted, and it works just fine. Place a Footman, a Knight and a Goblin Sapper on a test map. Change the Footman's allowed targets to Suicidal only. The Footman will only be able to attack the Sapper, and it will be unable to attack the knight. No triggers needed.

 

[Accname]

but therefor you need precious classifications which can be used for so many other things. did you really try the triggered solution? last time i did it worked pretty fine.

 

[Bogrim]

Actually classifications are best used for something like AI behavior, where spells and abilities are much easier to trigger.

 

[Accname]

whatfor classifications are best used is decided by what kind of map you are making and how complex it is going to be.
by default i would say try to use as little custom value and classifications of units in open systems as possible cause these can be used for many other deeds.
