Custom Armor Reduction Ability!

[AlwaysAndForever]

I have 3 different tiers of a tower with 3 abilities, each can reduce a different amount of armor!
Reduces a target enemy hero's armor by 1 per hit (unlimited).
Reduces a target enemy hero's armor by 2 per hit (unlimited).
Reduces a target enemy hero's armor by 3 per hit (unlimited).
If I don't attack the target after 5 seconds, the effect will be lost.

I looked at this thread
how to create Attack Modifier?
and came up with these two triggers
And it works but instead of reducing/adding negative bonus armor it reduces base armor!

You could probably add an Item Armor Bonus ability to the target with negative values. That should stack and affect both base armor and bonus armor the way you'd expect it to.

Alternatively, you could modify Inner Fire to apply the negative armor. Just use the Set Ability Field actions along with some Unit Indexing to track the Armor loss over time:

• Events
  • Unit - A unit Takes damage
• Conditions
  • (Level of Armor Reduction Toggle for (Damage source)) Greater than 0
  • (Damage From Normal Attack) Equal to True
  • ((Damage Target) is A Hero) Equal to True
  • ((Damage Target) belongs to an enemy of (Owner of (Damage source)).) Equal to True
  • ((Damage source) is in AR_UnitGroup.) Equal to True
• Actions
  • Custom script: local unit target
  • Custom script: local integer armorLoss
  • -------- --------
  • -------- Get the damage source and target --------
  • Set Variable AR_Source = (Damage source)
  • Set Variable AR_Target = (Damage Target)
  • Set Variable AR_Target_CV = (Custom value of AR_Target)
  • -------- --------
  • -------- Get the amount of armor reduction --------
  • If (Unit-type of AR_Source) Equal to Blood Tower then Set Variable AR_Amount[0] = 1
  • If (Unit-type of AR_Source) Equal to Blood Tower (Super) then Set Variable AR_Amount[0] = 2
  • If (Unit-type of AR_Source) Equal to Blood Tower (Ultra) then Set Variable AR_Amount[0] = 3
  • -------- --------
  • -------- Track this data locally --------
  • Custom script: set armorLoss = udg_AR_Amount[0]
  • Custom script: set target = udg_AR_Target
  • -------- --------
  • -------- Track the total amount of reduced armor --------
  • Set Variable AR_Amount[AR_Target_CV] = AR_Amount[AR_Target_CV] - AR_Amount[0]
  • -------- --------
  • -------- Apply the reduced armor --------
  • Ability - Set Ability: (Unit: AR_Dummy's Ability with Ability Code: Inner Fire (Armor Reduction))'s Integer Level Field: Defense Increase ('Inf2') of Level: 0 to AR_Amount[AR_Target_CV]
  • Unit - Increase level of Inner Fire (Armor Reduction) for AR_Dummy
  • Unit - Decrease level of Inner Fire (Armor Reduction) for AR_Dummy
  • Unit - Order AR_Dummy to Inner Fire AR_Target
  • -------- --------
  • Wait 5.00 seconds
  • -------- --------
  • -------- Get the data safely using the local variables from before --------
  • Custom script: set udg_AR_Amount[0] = armorLoss
  • Custom script: set udg_AR_Target = target
  • Set Variable AR_Target_CV = (Custom value of AR_Target)
  • -------- --------
  • -------- Undo the armor reduction from before --------
  • Set Variable AR_Amount[AR_Target_CV] = AR_Amount[AR_Target_CV] + AR_Amount[0]
  • -------- --------
  • -------- Apply the updated armor --------
  • Ability - Set Ability: (Unit: AR_Dummy's Ability with Ability Code: Inner Fire (Armor Reduction))'s Integer Level Field: Defense Increase ('Inf2') of Level: 0 to AR_Amount[AR_Target_CV]
  • Unit - Increase level of Inner Fire (Armor Reduction) for AR_Dummy
  • Unit - Decrease level of Inner Fire (Armor Reduction) for AR_Dummy
  • Unit - Order AR_Dummy to Inner Fire AR_Target
  • -------- --------
  • Custom script: set target = null

You can create the Dummy once and keep track of it all game:

• Events
  • Time - Elapsed game time is 0.01 seconds
• Conditions
• Actions
  • Unit - Create 1 Dummy for Player 1 (Red) at (Center of (playable map area))
  • Set Variable AR_Dummy = (Last created unit)
  • Unit - Add Inner Fire (Armor Reduction) to AR_Dummy

Armor was used in BonusMod so probably has the same issue with setting values not updating when changed but only when the ability is removed as bonus health/mana do.

IMO recasting Inner Fire is a better way to go. @AlwaysAndForever, do you intend for this armor reduction to affect to the attack that applies it? If so you’ll need to do some DamageEngine fuckery.

 

[AlwaysAndForever]

The problem was/is that the stack gets stuck after the first few hits and when I toggled off the ability, each hit reduced the negative bonus armor back to whatever it was!

This was the problem that prevented the stacking!
Set VariableSet AR_Amount[AR_TargetCV] = (AR_Amount[AR_TargetCV] + AR_Amount[0])

However, if I toggle the ability on and off, it starts counting from the previous remaining number!
For example, if I hit a hero 10 times and toggle the ability off and then on again, it starts counting from 10 and not 0!

you’ll need to do some DamageEngine fuckery.

Yeah sure with the knowledge I have!

 

[Pyrogasm]

I don’t think you’ve described your objective properly, and as a result Uncle crafted something for you that doesn’t exactly do what you expected it to.

Is the armor reduction supposed to stack up on the unit no matter which tower is attacking it, or is each tower progressively growing its own stacks of armor reduction that only applies once to each enemy (at its current strength)?

In the first case, yeah deactivating auto cast would do nothing if they re-attack before the reduction expires. In the second case, all of the armor reduction tracking you’re doing is on the wrong units. What happens if two different towers attack the same unit? What has priority, or do those multiple sources stack with/refresh each other?

Not having to worry about expiration, buff tracking, and stacking rules is a huge upside to using Inner Fire as Uncle showed. But in my opinion it’s unclear what you want to have happen so we can’t really troubleshoot. Also please show your triggers if they have changed since the last time you showed them here.

---

Modifying pre-mitigation damage with a trigger is not difficult; you are capable. You didn’t answer my question about the desired sequence, though.

 

[AlwaysAndForever]

Uncle made exactly what I wanted and for that I really appreciate it, but like I said stacking doesn't work properly!
Armor reduction supposed to stack up on the unit no matter which tower is attacking it, which works fine.
My problem now is that
If I attack a hero 5 times with -1 armor, the total armor should be -5 and after 5 seconds if I attack that hero again, it should be counted from 0 and not -5!

[Pyrogasm]

Put affected units in a group. Check the group periodically for units that no longer have the inner fire buff, and if so reset their entry in the array back to 0.

Still having the same problem and it doesn't seem to work!

Need help...About Armor Reduction.
First attack reduces armor by -1, the second and subsequent attacks reduces armor by -2!
Set VariableSet AR_Reduction = ((Load 0 of AR_I from AR_Hashtable.) + 1)
Set VariableSet AR_R = (Power(2.00, (Real(AR_I))))

I somehow want to add these actions to it, so each tower has its own value! How can I do this?
