General Unit Event - A unit is attacked pre-executing!

[komapatient]

Okay, I need some help. Currently I am working on a project where barrack-type units gain XP by either attacking or killing enemy units.

I got the basic triggers working and doing fine with one small issue I noticed.

To detect if a unit attacks another unit and earns itself a bit of XP I use the General Unit event 'A unit is attacked'.

The issue I discovered is whenever a unit has a respectively long charge attack time (fiends or mountain giants take a long time to actually finish their attack) a player is able to retreat the unit from attacking in the last part of the striking blow so that the General unit event trigger rolls but actually no damage is dealt. Good players can abuse this to level up their units on a simple level 1 creep with no effort and I bet they will and this would render my map unplayable!

The event says: 'A unit is attacked'. So I assumed it will be damaged - unfortunately it seems to mean: 'A unit is about to be attacked'.

How can I check if a unit actually got hurted by a strike of an attacker so my trigger can pay XP to the attacker only when actually damage was dealt?

Oh yeah, it's like that.


Anyway, the only way you can solve it is using Specific Unit takes Damage.

If you need more help, tell me.

You'll have to create a damage detection system so you can use the event A unit is damaged. Remove your event from you xp system trigger and Create the following trigger.

Events:
Map Initialization
Actions:
Select all Units in Playable Map Area and do actions.
Add the Event Picked unit is Dealt damage to <your xp trigger>.

And

Events:
A unit enters Playable map area
Actions:
Add the Event Triggering unit is Dealt damage to <your xp trigger>

You'll need to alter your xp trigger so that it uses damaging unit rather than attacking unit as well.

Edit: Note I freehanded this so you'll have to find the exact lines yourself.

Ah - okay! This is a good hint. Yet I seem to have trouble to specify a variable for it.

Which type of variable would apply to Specific Unit Event? I tried Unit and Unit Group which both of them would not show up

WOW! This is pure awesomeness.. I'm so sorry my give away rep supply has gone out last 24 hrs - but as soon I am able to go again be sure you're my #1 priority !!!

Umm. I was about to say that.

Anyway, that's how you make a Specific Unit event only into a Generic Unit. :thup:

Anyways it works now Both of you many thanks!!! xD

I already thought of throwing my map into the trash bin ;D

There is one error with that though. Heroes will get added after each revival, which means they will fire the trigger multiple times. Add a unit group add and a unit is in group == false condition.
