CTF Flag parenting triggers?

You can do that with parenting and filters. I messed around with something like that for this map (vmf included).

*bump*

I am also trying to find this out at the moment, I want to reset dropped flags on touch. I've looked everywhere and doesn't seem like anyone else has worked it out. I looked at the map linked but I couldn't really tell what was going on with only one player on the map. Just that I died if I dropped the flag. Could anyone explain how to set-up a 'reset on touch' ctf ?

When one entity "A" is parented to entity "B", "A" takes on "B"'s movement hierarchy. Basically, wherever "B" goes, "A" will go as well, and "A" will remain in the same orientation to "B" from when it was first parented to it.

To do the flag return via only a certain team touching it, just use a trigger_multiple and a filter_activator_tfteam. It's the same concept as team specific doors:
TF2/Team-Specific Doors

There was some discussion in the Steam forums a few months back about a similar concept here:

There isn't a way to change a flag's return timer that I know of after a map's been compiled, but what you could do is send a "KillHierarchy" input to the flag to remove it and all of the entities parented to it from the world, then respawn it and it's "children" through a point_template.

More info about that below:

You'll need to have not only have the flag in the point_template's properties box, but the entities parented to the flag as well, otherwise things can get buggy.
