Passive Mana Shield

I have seen a lot of posts on this but i don't know jass, sill, i got to thinking


that's what i have, now i was thinking i could set a variable to life of attacked unit + damage taken. But i can't find that any where. help?

this is what i want i just don't know how to get there.

can any one point me in the right direction?

You need a specific unit event, "Takes Damage". You can register it once your unit enters the map with some trigger action (Trigger - Add new event).
The damage taken is a real number and event based, so it's somewhere in that list.

Ty i have made the variable, and now the trigger but this doesn't work why not?

oh, found out i dont need a variable for this,doesnt matter this is what i tried and it still doesn't work any ideas?


Again this doesn't any thing as far as i can tell.

As jonas mentioned above, you need to use the 'Takes Damage' event. 'Damage Taken' event response does not work with 'Is attacked' event. Then you have to set up the event with 'Trigger - Add new event', unless the unit is pre-placed in the map. You could also alternatively look into Damage detection systems for GUI, but that would most likely make things more complicated.

Ty for the replies this almost works

The problem is that the damage seems to stack. at first mana is taken out normally as one would expect but after a few attacks it is taken out at an increasing rate. later on all the manna will be taken out with just one hit. It almost looks like damage taken is a variable that has it's value added to every time a unit is attacked.

That's because every time the unit is attacked the event is being added again and again, so it will trigger multiple times. You have to add the 'Takes damage' event from somewhere else, like jonas suggested above when the unit enters the map, you make a variable of it (the unit) and use it to add the event. Then you remove the 'Is attacked' event from the actual trigger so that the event section will be empty (the added event will still be there even though it cannot be seen in the editor).

I suggest making a trigger:

and remove the "unit is attacked" event from Energy Shield passive

hrm, In my map there maybe hundreds of units with this ability, will that cause crash?

Thank you guys so much this seems to work does it leak? I don't fully under stand how this works, sorry for my ignorance.
First trigger:

Second trigger:



see any leaks? or is this air tight?

The event itself leaks. You create 1 event for every unit with the ability, but you never remove those events after a unit died.
Unfortunately there is not much you can do. You have to simply take it since your possibilities of removing the event at run time are limited. At least with GUI that is.

How quick could this become a problem and crash the game?

Depends on too many factors to be answered.
For every unit you create one event. A single event cant take too much memory, lets be VERY generous and say its 50 bytes. Until you fill 1 GB of RAM with 50 bytes of leaked events it would take 21474836 units in your map. (Please note that these units must not exist at the same time, if you spawn and kill 10000 units every second this might happen eventually)

I can live with that most i have ever seen one person get is 5000. I will increase their price and stats so that one can make do with a few.

Final check.
I also wanted some kind of animation, so i added a dummy unit and it has the energy shield model i wanted, every thing looks fine to me so, i just wanted to make sure with the experts before rapping things up.




This is the final product (unless some one findes something)
Ty guys, +rep

(Position of (Attacked Unit)) leaks a point when you create the dummy unit. Use a point variable and store the location in it, and create the dummy using the variable.
Then remove the variable with the custom script "call RemoveLocation (udg_YourVariable)".
Also, don't use the wait function there as it is possible for global variables (last created unit in this case) to be overwritten. Better to just add an expiration timer to the last created unit.

what about this this kinda works too but the animation sticks around to long. does this have any leaks? Is their a way to cut the time it takes for it to disappear in half?

Using the Special Effect action causes the effect to play out even if destroyed without delay (depending on effect). Using the dummy unit and expiration timer like I suggested above should let you control the length of the effect by using shorter expiration timers. This might give you a better result, give it a shot.

There are no leaks, except the event itself.

I'm terrible at all this(reason why i don't no how timers work) will this effectively take out half the mana from attacks.

> half the mana from attacks
Yes.

> ((Level of Energy Shield (real passive) for (Entering unit)) Equal to 2) and ((Mana of (Entering unit)) Greater than or equal to 25.00)
In your first trigger, change this to:
(Level of Energy Shield (real passive) for (Triggering unit)) Greater than 0)

Remove the other condition.
Unless, of course, you have something else in your mind that I'm aware of.

> Using the dummy unit and expiration timer like I suggested above should let you control the length...
Not such a good idea imo. It may lag the game, especially in this case. Every damage received will create a unit.
As it is, creating and destroying effect work as it should, as long as the animation is played correctly.

Boom made with a Damage Engine

Added a detail to the spell (you can remove it by getting rid of the condition and the dummy casting the debuff) That fizzles the unit making temporarily disabled.

Didn't know this thread was 3 god damn years old...
