[General] Damage Detection function

[Fakuspakus]

I heard that newest patch added a way to detect damage like GDD does, but I can't find it anywhere.
Could anyone show me an example?

Likely they did not add new event to GUI yet, you can find here:
Patch 1.31.1 Live Update

Yes, there are no GUI equivalents for the new natives. Even though there are now new natives by Blizzard for damage detection, I'd still suggest to use Damage Engine or something, since it's a lot easier to use than to make your own triggers. Also Damage Engine for example has a lot of other features too.

My fear is that those might break in future wc3 patches.

They won't. They use just the same coding that you would have to do yourself anyway. They are not some third-party-tools, they are just JASS code made ready for you to use.

I would recommend using Damage Engine 5.4.2.0. Yeah the events aren't public to GUI yet, but you wouldn't believe the hurdles that need to be gone over in order to compensate of the glitchy and complex rhythm of WarCraft 3's damage processing. In the end you'd want to use a system as flushed out as Damage Engine if you want to take advantage of all the game has to offer - there's no other system like it.

A basic damage detection trigger looks like this:

• On Damage
  • Events
    • Game - Value of DamageEvent becomes Equal to 1.00
  • Conditions
  • Actions
    • Game - Display to (All Players) the text (Name of DamageEventSource) + Damaged + (Name of DamageEventTarget) + for (DamageEventAmount)

Basic modification to double the damage looks like this:

• Mod Damage
  • Events
    • Game - Value of DamageModifierEvent becomes Equal to 1.00
  • Conditions
  • Actions
    • Set DamageEventAmount = (DamageEventAmount x 2)

Those cover really simple scenarios. Here's how you detect things like Ranged or Spell Damage:

• Ranged Damage
  • Events
    • Game - Value of DamageEvent becomes Equal to 1.00
  • Conditions
    • IsDamageRanged Equal to True
  • Actions

• Spell Damage
  • Events
    • Game - Value of DamageEvent becomes Equal to 1.00
  • Conditions
    • IsDamageSpell Equal to True
  • Actions

And here's a more complex feature recently added about how you can "deflect" an attack from the target back at the source:

• Deflect Damage
  • Events
    • Game - Value of DamageModifierEvent becomes Equal to 1.00
  • Conditions
  • Actions
    • Unit - Cause DamageEventTarget to damage DamageEventSource for DamageEventAmount using attack type CONVERTED_ATTACK_TYPE[DamageEventAttackT] and damage type CONVERTED_DAMAGE_TYPE[DamageEventDamageT]
    • Set DamageEventAmount = 0.00

Here's "dodging" damage (no impact sound is played):

• Dodge Damage
  • Events
    • Game - Value of DamageModifierEvent becomes Equal to 1.00
  • Conditions
  • Actions
    • Set DamageEventWeaponT = WEAPON_TYPE_NONE
    • Set DamageEventArmorT = ARMOR_TYPE_NONE
    • Set DamageEventAmount = 0.00
