Enumerate for specific map object

[Motion_Blurz]

Is there any nifty way of enumerating maps for a specific map object and then having it generate either a trigger zone or IP?  Say I want to find every radio_tower the map has in it.  How can I do that in a more time efficient means than visually scanning the map manually?

Thanks in advance.

You scan the map via script then save that information for later use. https://wiki.hoggitworld.com/view/DCS_func_searchObjects

If scanning the whole map I like to save the object type name and the coordinates since the object ID cannot be relied on. Depending on the object searched for your results may or may not be all that practical. 

I ripped this out of a rather complicated mission script where it had a number of different input values. Anyway I used this primarily to just find and more easily associate an object with the object typename. Just place an F10 mark panel on the map, edit the box to say "searchObj" and it will scan a 500m radius around that point. For everything it detects it draws a mark panel over it with the object typename as the text for it. Change the 500 to a larger value if you want. Just know it will take a while because most of the maps have several million objects on them and checking even a 10km radius can take several minutes. Not to mention the f10 map really doesn't like rendering tens of thousands of mark panels.

             local volS = { id = world.VolumeType.SPHERE,  params = {point = newPoint } }
             volS.params.radius = vars.radius or 500
            
             local searchInclude = {}
             if vars.searchFor and vars.searchFor[1] then
                for i = 1, #vars.searchFor do
                    searchInclude[vars.searchFor[i]] = true
                end
             else
