How to detect if a unit is damaged

[Haumin007]

Well, first time ask question here, point me out if I have done something wrong.

Base on my topic, I want to ask that is there any way to detect that if a unit is being damaged instead of being attacked. If I put the event 'a unit is attacked', then my action will start when a unit is 'attempt' to attack another unit, this mean that even I stop the attack, the action will still run.

I am sure that this can be done but I don't know how, whether it need JASS or just GUI will do it.

Hope somebody can help me.

if the unit you want to detect is damaged is already in-game at Map Initialization, you can use the Unit - Specific Unit event. it has a Takes Damage preset field.

if it is not, you should make two triggers. the first one would be a trigger saving that unit you want the damage detected in a variable and making it the event for the damage detecting trigger. the trigger below saves the unit created:

• Actions
  • Unit - Create 1 Footman for Player 1 (Red) at (Center of (Playable map area)) facing Default building facing degrees
  • Set UnitDetect = (Last created unit)
  • Trigger - Add to (Damage Detection Trigger) the event (Unit - UnitDetect Takes damage)

UnitDetect is the unit detected (in this example the footman created)
Damage Detection Trigger is the trigger whose event is that Specific Unit event.

Thanks, now I understand how to do it already. + rep to you.

Hey, I got myself into another trouble, my trigger cannot detects the so-called Damaging unit, how can I detect it?

It can be done in 3 triggers.
First Trigger:

Show

• DamageDetectStartup
  • Events
    • Time - Elapsed game time is 0.00 seconds
  • Conditions
  • Actions
    • Unit Group - Pick every unit in (Units in (Playable map area)) and do (Actions)
      • Loop - Actions
        • Trigger - Add to DamageDetect <gen> the event (Unit - (Picked unit) Takes damage)

Second Trigger:

Show

• DamageDetectStartup2
  • Events
    • Unit - A unit enters (Playable map area)
  • Conditions
  • Actions
    • Trigger - Add to DamageDetect <gen> the event (Unit - (Triggering unit) Takes damage)

Last Trigger:

Show

• DamageDetect
  • Events
  • Conditions
  • Actions
    • ===Attacked_Position, is a Point Variable===
    • Set Attacked_Position = (Position of (Attacked unit))
    • Floating Text - Create floating text that reads (String((Integer((Damage taken))))) at Attacked_Position with Z offset 0.00, using font size 7.00, color (100.00%, 100.00%, 0.00%), and 25.00% transparency
    • Floating Text - Set the velocity of (Last created floating text) to 40.00 towards 90.00 degrees
    • Floating Text - Change (Last created floating text): Disable permanence
    • Floating Text - Change the lifespan of (Last created floating text) to 2.00 seconds
    • Floating Text - Change the fading age of (Last created floating text) to 1.00 seconds
    • Custom script: call RemoveLocation(udg_Attacked_Position)

kaizar's triggers will show you the damage taken of the attacked/damaged unit.

and, there is a unit action Event Response - Damage Source. you can use that action together with the Unit - Unit Takes Damage event to detect which unit deals the damage, or the damaging unit.

GUI Damage Detection System

Go here:

GUI-Friendly Damage Detection System

This system allows you to use the event of a Real Number becoming equal to 0.00 to detect damage from a known source, a known target, and a known amount, all just by pasting this guys triggers into your map. There's a good set of instructions on the forum there that explain how to use the system to get the damaged unit, the source unit, and the amount of damage. It's really easy to implement and fully GUI friendly so if you don't know JASS you don't have to worry : )

You guys with your Trigger - add event actions... are you using WEU for this? It is not in World Editor, so careful when passing this kind of tip to a noob.

 

[Haumin007]

Thanks for all of you, I will try to make my trigger and if I encounter another problem I will ask u all again.

Damaged Unit can also be referred by - Triggering Unit FYI

No, it's in the default Editor. It's the action Trigger - Add New Event. When you go to Actions, press "U" to lead yourself on the Unit actions and then press the Up arrow. There is the action Trigger - Add new event.
