land test function question

[C6_Hellfrog]

didn't found any info about it :

 

is there a way to know if at a point of the land map there is an object (that is not a unit) ? building, tree, and so on ...

any way to check that or impossible ?

 

is there a way to access read buildings heights somewhere ?

Edit : maybe with SceneryObject.getDescByName() ? , or use infos from scripts/database/db_categories.lua, but I still don't know how to ...

Edit : with world.searchObjects() on a short segment ?

but how to use a land point to match with these infos ? = knowing a specif land point, want to know what is there, its name and properties... someone already tried that ?

You can use world.searchObjects to find scenery objects within a given volume. It won't find trees, but normal buildings should be accessible. I believe the smallest type of object it "sees" are the light polls.

 

I need to state there is likely a caveat. At least the last time I checked, it doesn't work at all on Nevada.

 

Any.getDescByName() basically just takes a string value and returns whatever is the description for that object without the need to directly access a world object and using getDesc() on it.

another idea came to me with that.

 

Do you think we can use it to compensate lack of buildings detection in LOS function ?

knowing target.point and unit.point, we could check all the line between the both, and calculate if a building is present, if its height is too much to maintain the LOS and will break it... a thing the LOS function cannot do.

 

or it wil not be precise enough or it will consume too muche processor time / FPS impact ?

 

because I think someone else should already have had the idea I suppose...

 

but to use it we have to edit the IA scripts ... to avoid that bad snipper ability they have...
