This... is... amazing! One of the biggest challenges I've found with ship design is how to format it for posting on the forums. And you've gone and fixed it for us. Can't wait to try it out!

Re: GURPS Spaceships Design Spreadsheet
 
Okay, not sure if I did something wrong, or what's going on, but I'm getting some bugs in the latest build. Troop Strength is displaying as 0 (despite the vessel having armor, weapons, maneuvering capability, etc); Projectile weapons are displaying Err:502 in their Accel stat; and every line on the Output page is also displaying Err:502. I'm using Open Office 3.3.0.

EDIT: Oh, and the Conventional Gun is also incorrectly getting the "Improved" option, x2 RoF, despite that only being available to energy weapons.

Re: GURPS Spaceships Design Spreadsheet
 
Version 2.00 Beta 12

-Fixed issue with Missile Weapon Accel stat which caused the Output Sheet to error out in OpenOffice
-Corrected Troop Strength, which wasn't taking into account dDR or dHP (only Force Field dDR was being used).
-Corrected weapon RoF to increase with Space Combat Turn Length setting.

I don't see where Improved is limited to energy weapons. In fact, the description of Improved specifically says that this could represent a Multi-Barrel weapon, which could easily be used in the design of a Conventional gun. In fact, the note on the RoF table on p. 58 specifically mentions Improved guns.

Thanks! I'll give it a try again.

Well, it's listed specifically under the Options for Beam Weapons. Rapid Fire and Very Rapid Fire are listed separately for both Beams and Conventional guns. It thus implies that Improved is an option exclusively for energy weapons. Not a big deal though; your argument makes sense too.

See my edit. I also just re-updated because I noticed RoF wasn't taking into account Space Combat Turn Length.

Hmm. I'm still getting both of these errors. All projectiles are still displaying an Error in their Accel stat (and thus spoiling the Output page), and TS is still displaying 0 (unless a Force Screen is present).

EDIT: The fact that having effectively 0 DR causes the TS calculation to return 0 indicates that it may not be including HP correctly in the formula. TS is based on dHP + Avg dDR, multiplied by number of combat systems (weapons + defensive ECM) and factors derived from Hnd and TL.

I should have this fixed now. In fact, I fixed it several times, and something odd is going on with my system because it wasn't saving the changes for some reason.

Re: GURPS Spaceships Design Spreadsheet
 
Version 2.00 Beta 14

-Added descriptive Error messages to the Ship Option checkboxes

-Corrected cost for individually selected Stardrive (Reactionless) engines
-Corrected some Engine Options a little bit better (NMP, Pseudo Velocity, Singularity Drive, and Boost Drive)
-Corrected ship stats for Boost Drive option
-Cleaned up the display of Design Switches, Features, & Notes:
(note: Plan on revamping this one for the final release, when I plan on moving a lot of things around a bit)
-Probably other bug fixes & adjustments
