[Trigger] Miniature damage detection system and Backstab

[StaberFire]

I have a problem with a quick non-MUI damage detection system I made in GUI. I have a Backstab Ability that works just fine and triggers when the attacked unit takes damage from the back.

• Backstab Setup
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Level of Dual Agility for (Attacking unit)) Greater than or equal to 1
  • Actions
    • Set tempAttacker = (Attacking unit)
    • Set tempAttacked = (Attacked unit)
    • Trigger - Add to Backstab Damage <gen> the event (Unit - tempAttacked's life becomes Less than (Life of tempAttacked))

• Backstab Damage
  • Events
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • And - All (Conditions) are true
          • Conditions
            • (Facing of tempAttacked) Less than or equal to ((Facing of tempAttacker) + 15.00)
            • (Facing of tempAttacked) Greater than or equal to ((Facing of tempAttacker) - 15.00)
      • Then - Actions
        • Unit - Cause tempAttacker to damage tempAttacked, dealing 25.00 damage of attack type Pierce and damage type Acid
        • Special Effect - Create a special effect attached to the chest of tempAttacked using Abilities\Weapons\HydraliskImpact\HydraliskImpact.mdl
        • Special Effect - Destroy (Last created special effect)
        • Floating Text - Create floating text that reads Backstab! above tempAttacked with Z offset 0.00, using font size 7.50, color (100.00%, 50.00%, 0.00%), and 0.00% transparency
        • Floating Text - Change (Last created floating text): Disable permanence
        • Floating Text - Set the velocity of (Last created floating text) to 32.00 towards 90.00 degrees
        • Floating Text - Change the lifespan of (Last created floating text) to 3.00 seconds
        • Floating Text - Change the fading age of (Last created floating text) to 0.20 seconds
      • Else - Actions
        • Do nothing

Then I have another ability that causes the unit's next attack to deal additional damage. This is where the problem is. The buff has infinite (-1) duration and is only removed when the unit's attack hits. This uses the same system as the Backstab ability, but does not work. It triggers upon the unit's second attack, rather than its first.

• Stealth effect setup
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • ((Attacking unit) has buff Stealth Technique ) Equal to True
  • Actions
    • Set tempAttacker2 = (Attacking unit)
    • Set tempAttacked2 = (Attacked unit)
    • Trigger - Add to Stealth effect <gen> the event (Unit - tempAttacked2's life becomes Less than (Life of tempAttacked2))

• Stealth effect
  • Events
  • Conditions
  • Actions
    • Unit - Cause tempAttacker2 to damage tempAttacked2, dealing 50.00 damage of attack type Pierce and damage type Poison
    • Unit - Remove Stealth Technique buff from tempAttacker2
    • Animation - Change tempAttacker2's vertex coloring to (100.00%, 100.00%, 100.00%) with 0.00% transparency
    • Floating Text - Create floating text that reads 50! above tempAttacked2 with Z offset 0.00, using font size 7.50, color (100.00%, 25.00%, 0.00%), and 0.00% transparency
    • Floating Text - Change (Last created floating text): Disable permanence
    • Floating Text - Set the velocity of (Last created floating text) to 32.00 towards 90.00 degrees
    • Floating Text - Change the lifespan of (Last created floating text) to 3.00 seconds
    • Floating Text - Change the fading age of (Last created floating text) to 0.20 seconds

Why does it trigger on the second attack instead of the first, and how can I fix it?

• Trigger - Add to Stealth effect <gen> the event (Unit - tempAttacked2's life becomes Less than (Life of tempAttacked2))

This means that if the life of the attacked unit, is less than the life of the attacked unit.
And cause it gets less before, this event was added, its the second attack.

(Why dont you just

• Trigger - Add to Stealth effect <gen> the event (Unit - tempAttacked2 is attacked

1) Remove 'Do Nothing'
2) I´ll take a look.

Edit: Btw the spell could bug if a unit damages the target while the backstaber is still attacking.

 

[StaberFire]

Because that will execute before damage is dealt. I guess I didn't notice that with Backstab because it's hard to tell if it's the right facing angle, so it could have been the same problem. Anyways, that makes alot of sense, thank you. I'll try to find a way around it.

 

[Paladon]

Solved, gj blood. That makes sense for me.

 

[StaberFire]

The problem has been identified, but that doesn't mean it was solved. =P
Tried storing the attacked unit's life in a variable beforehand, but it presented the same problem.

 

[raft_pl]

I guess its because your first trigger adds the event to the second trigger, which deals the real damage... Thats why it bugs, first attack adds event, second attack triggers damage.

Solution? Merge these two triggers into one... If you bother about the delay, just add a short wait and use some variables.

(may be plotting shi-, im kinda sleepy now, cant even read what i wrote... duh)

 

[StaberFire]

Alright, I made the event for the trigger "A unit is attacked" and used waits based on animation properties to make it look good. The Stealth ability works fine now, but I still have the same problem with the Backstab. It doesn't work the first time the Hero attacks a new unit, only on the second attack.

[TheBlooddancer]

Why didn't you just use the line i said? It should work.

 

[Eccho]

I am not 100% sure that (attacking unit) stays after waits... Neither goes to attacked unit. Replace attacked unit with triggering unit (thats a start well...)

 

[StaberFire]

They do work after waits. If they didn't, the trigger wouldn't work at all.

And @TheBlooddancer, that would basically just be the same event, I don't really see the point in using two triggers for that.
