Unit Indexing and Deindexing

[Zeatherann]

I have an issue with unit indexing in that structures built are not registered with region entered events. This is easy to get around. However, deindexing units by checking for the undefend order doesn't work with buildings because as soon as they get the ability they are ordered to undefend?

You would probably have to add special cases. Idk if you're using an indexer here or one of your own, but you should add a death register event. If a unit dies, and the unit is a building, then deindex the unit.

Undefend is actually only used for cases where units are removed (e.g., via RemoveUnit()). Those are actually really easy to get around in map-specific cases (just deindex a unit when you use the RemoveUnit() native), so just disregard the defend ability and use a regular death event + be considerate with RemoveUnit() (or write a custom RemoveUnit() function).

How can you get around undefend by removing a unit? I do know that it is ordered to undefend on death and remove (twice if you use RemoveUnit()). I was more curious with how to stop a building from undefending when it gets an ability based on defend.

I didn't mean you should remove the unit, I meant that you can just deindex it if you happen to remove a structure. Otherwise you can just check for death (in the case of buildings only). That way, you really don't need to rely on the undefend, and you can ignore it if the unit is a building (in the deindexing trigger). It is sort of a band-aid solution though, and I am aware that it doesn't answer your main question.

Ah, I will try this solution.

It is annoying that there is no easier way to do it, but for now the band-aid solution works.

I have 2 questions on you:

1. Are you using some already made unit indexer, or self written one?
2. why you even need to index buildings?

 

[Zeatherann]

It is a self made one, I want to index every unit (I do need to index some of the buildings though).

 

[edo494]

oh, I wanted to know if the already existing indexers dont index the buildings as well. Time for some testing

 

[Zeatherann]

They probably don't. At least, they won't catch constructed buildings (as unit enters region events are used).
