Garrisoned Guard Tower

CabalCore · Cyborg Soldier **Joined**: 23 Oct 2013

I got the idea to make the Guard Tower in TD a garrisoned defense. The idea came from the pillbox in RA.

I tried doing a copy and paste from the pillbox and it worked fine for the most part. The problem I'm having is trying to get the port offsets, port yaws and port cones correct for 8 facings rather than 6 facings that the pillbox uses.

Would someone be able to help me out with this?

I'm going to assume 4 ports so that I can outline the procedure off the top of my head without having to calculate or test anything.

The default weapon armament defines a local offset of 256,0,256, so you can find the PortOffsets by rotating this around the 4 facings:

PortOffsets: 256,0,256, 0,-256,256, -256,0,256, 0,256,256

For 8 ports you just need to insert the intermediate rotations with sqrt(2)*256 on the x and y.

The port yaws are measured with 1024 units per rotation, so you should have each port facing outwards:

PortYaws: 0, 256, 512, 768

For 8 ports you'll have 128, 384, and so on.

The PortCones define the angle that each port can fire through. It should be set slightly larger than the angle between ports. 1024 / 4 / 2 = 128, so

PortCones: 130, 130, 130, 130

For 8 ports you'll want to halve these.

You can turn on "Show Combat Geometry" in the debug options to have the game draw the resulting cones.

Did some experimenting first to make sure I got it down.

It has a single firing muzzle flash pointing up, right, down and left. though when firing diagonally, I see dual muzzle flashes as though it were firing twice.

So basically I have to go halfway between the portoffsets, portyaws and portcones. So it would be something like.

PortYaws: 0, 128, 256, 384, 512, 768, 896, 1024
PortCones: 65, 65, 65, 65, 65, 65, 65, 65

Thanks to your reply, I think I have the PortYaws and PortCones done. Though I'm still having slight difficulty for the PortOffsets. I'm guessing I'd go halfway between them.

And also, is the firing sequence in a clockwise rotation?

EDIT: this is what I did.

Code:

PortOffsets: 256,0,256, 128,-128,256, 0,-256,256, -128,-128,256, -256,0,256, -128,128,256, 0,256,256, 128,128,256
PortYaws: 0, 128, 256, 384, 512, 640, 768, 896
PortCones: 65, 65, 65, 65, 65, 65, 65, 65

The garrisoned guard tower fires in 8 facings in an octagonal pattern.

EDIT: Is there a way to replicate RA2's battle fortress behavior? And what I mean by that is to have a vehicle with an initial primary weapon and add additional weapons with garrisoned infantry?
