Title: Having Trouble with weapons not engaging.
Post by: Doc on February 03, 2022, 04:57:03 PM: I am having trouble with my PDC laser turrets not engaging missiles. Four nice little destroyers are getting, well, destroyed, and I'm not sure what I'm doing wrong. Posted ship design and attached screenshots of the Fire Control Setup & Combat so you can see that all 18 missiles are getting through. Not sure what I'm doing wrong, but I know I'm very new! Any help is appreciated. Let me know if I need to post more info, or post it differently or something. Thanks!

PS, ship design help is always appreciated. Very little idea what I'm doing.

Yes. You have RES-100 sensors, which will detect missiles at 57.4m x (0.3/100)^2 = 516 km. This is less than the final fire range of 10,000 km, so you are basically unable to detect the missiles until they hit you. Note that when trying to detect a target smaller than the sensor resolution, the range at which you could detect that target drops off quadratically, i.e. as (target_size / sensor_resolution)^2.

Also note that you do not need to "open fire" for final fire PD to function, in fact doing this can be detrimental as it incurs a fire delay which may prevent the weapons from firing.

Oh, my, GOD. Thank you. Stupid rookie mistake.

I haven't, because I'm SMART and READ THE DOCUMENTATION.

Please don't ask me how I know about the fire delay thing... ::)

Ok Steve, you just made my whole day with that! LOL, makes me feel I lot better when I go back to fix my own stupidity! :)
