Ok, so after playing "The Blade Itself" from Blueplanet, I was curious about how the mission designer managed to give the player control over what warships the Katana's railguns and torpedos fire at, and how they displayed all that targeting information on screen. I've looked through the mission file, and I can't find the events that do that, so I would appreciate either an explanation of that mission's structure, or some advice on how to replicate that effect.

[Darius]

The mission uses bp2-csc-sct.tbm, found in the tables folder.

[Apollo]

Thanks! Now I just need to modify it for other warships.

[Apollo]

Ok, I got it to display on screen, but the targeting doesn't seem to have much of an effect-I can change modes with the arrow keys, but it doesn't seem to change the turret's targets like its supposed to.

EDIT: I fixed it!

[SaltyWaffles]

Apollo, can you post what you did (and how you fixed the problem)? I'd love to give something like that a shot myself, and it seems likely that I'll run into the same problem.

[Apollo]

Sure.

Code: [Select]

;The CSC script. Messy and unreadable, but functional enough to allow effective control over capital ship turrets.

If I remember correctly, It had to do with csc.acnum (I believe that controls the weapon selection with the up and down arrows). Although, since I modifed the script without any scripting knowledge, I'm not entirely sure. I'm amazed I even got it work right.

EDIT: If you want to use it with another ship (and you probably will, since the Orff's weapons came from a mod I'm working on), make sure that all of the ship's turrets have generic names (turret01, turret02, etc.). Otherwise, it won't detect it.
