Hey asd,
I just had a really weird idea I thought was worth sharing.
What if, instead of KOTH, you made the base gamemode TOW-KOTH?
(by "TOW-KOTH", I basically mean Tug of War payload but the cart periodically scores your team PD points while it's in the enemy base.)
This would satisfy the lack of push-and-pull in the gamemode that abp brought up, and help discourage those unsatisfying rounds where some no-good engineer sets up on mid and wins the round without the flags ever really coming into play.
The pieces for it are already there, as well; the point is an orecar:
which sits on an unbroken track that goes into the enemy base:
Of course, it's not exactly free of issues.
For instance, the orecar moving would create a MASSIVE sightline on mid, so mid would need a route or two added that lets teams get around that.
Also, it would mean that the flags would become a win-more mechanic, where a team capable of pushing the orecar into the enemy base is capable of grabbing the enemy flag, whereas the enemy team isn't capable of pushing through mid... or are they? If the orecar is down one of the two lanes that lead to mid, it means you can take the other one to get behind the attacking team and grab their flag.
So it might be amazing?
Oh, also, when the orecar drops gold, the gold can flip upside down to become underground and totally invisible:
And the ground under the displacements isn't nodraw, so it has to bake a bunch of lighting information that inflates your filesize and VRAD compile time.
And this wall under the displacements isn't flush with the ground, which could become a minor optimisation issue down the line:
Happy mapping!
