[Trigger] Saving Damaged Unit into a Unit Group

[Blightsower]

Hi, it has been a while since I last posted here. I made this approach that when I damage a unit it will be saved on a unit group to avoid unwanted damage. I've achieved that but there is a problem. The units we're saved on a global unit group, as a result other missile will not deal damage. I've written this using indexing but it has the same problem as the current one. I need desperate help. Thanks

I've also attached a test map containing the ability. Oh, by the way the ability is a "Rake" type spell (throws projectile to damage enemies then return to the caster damaging units in its path). Also, Power = agility.

I'm not sure if I get the question right, but if you want to damage a unit by this ability only once (either by sending the missile forward or when it gets back) all you need to do is check if picked unit is in the "already damaged" unit group.

If that is not the case, I would advise using indexing technique and using a unit group array. Basically you would check the following:
My_Index = Instance of the spell
If(unit is in My_Group[My_Instance] == false) then damage unit and add unit to My_Group[My_Instance] else do nothing as the unit was already damaged by this instace


Edit:
Also, I see you're using hashtables. I advise using arrays and indexing technique for "every 0.03 second" loops.

 

[Blightsower]

thanks you for the response. yes, that is almost it however indexed groups offer the same result. i think my problem with indexed group is the right way to dispose it. do you just overwrite it with the new group or destroy it then overwrite it? my guess is just overwrite it.

 

[Nichilus]

Groups are like special effects in the sense that if you don't destroy them when you're done with them, then they leak memory.

When instance of spell ends, you remove everything that may leak and then deindex it (= overwrite that instance with the last instance).
Do note that it is important HOW you create a unit group.

For example:
If you do this:

• Unit Group - Add unit to My_UnitGroup

But My_UnitGroup was destroyed (or not initialized), then you "add unit to null" which means you never add the unit anywhere, hence if you later check the same unit again for "Unit is in My_UnitGroup == true", then it will always fail the check and allow your trigger to damage the unit again.

However the "Unit Group - Add unit to unit group" actions is not the same as this:

• Set My_UnitGroup = (Units in.... )

This action first creates the unit group and add the picked units inside it. If you use this action in the loop trigger, it won't resolve your problem, as you will be overwriting that one variable with new unit group each time you fire the trigger.

Imo the best option is this:

• Custom script: if My_UnitGroup == null then
• Custom script: My_UnitGroup = CreateGroup()
• Custom script: endif

Use this when you start the spell. This checks if the unit group == null (meaning it was not created) and if so, you create the unit group.
Then you just use the "Unit Group - Add unit to unit group".
Of course, this is just for one unit group. You will need to remake it to make it work for arrays instead.

 

[Blightsower]

wow! i didnt know that. thank you for enlightening me

Edit: somehow its giving me an error when i use My_UnitGroup = CreateGroup()... should i write it like "set My_UnitGroup = CreateGroup()"? this one gives no errors. "udg_My_UnitGroup=CreateGroup" also creates an error

 

[Nichilus]

this works for me:

• Custom script: set udg_MyGroup = CreateGroup()

 

[Blightsower]

i see, thanks ill rewrite it maybe next week
