Hello! I decided that i would like to start creating my very own Free space campaign. I already have the story line in mind, i just have afew questions about freds.
1: How do i save files as VP? So that i can try missions i create out?
VP files are not needed to get things working.
VP file is a container that is usually used in campaign/mod distribution for matters of convenience for users. But in reality, VP file contains a structure exactly similar to what you would find in the ../data/ folder, either in the main FS2 directory or in a mod directory - that is, the top level of any VP is called data, and there's directories like missions, maps, models, tables etc. etc. that are added to the collective /data that the game uses. In short, the game looks at what it has at it's disposal, and combines all the data in both VP's and data directories in the root and enabled mod folders.
The only difference is that if there's a similarly named file in a data folder and a VP file, the file in the data folder will take precedence.
So, when you're building up your mod, campaign or whatever, create a mod folder and inside that, put ../modfolder/data/ and subfolders for missions, maps, tables et cetera.
As to how to pack your mod's data folder into a VP, there's the older VP Mage (found on Hard Light Wiki) and Maja VP editor (found with forum search). The VPMage does have it's tricks, though, but once you learn it it's pretty conclusive to use. Maja VP editor was actually more refined IMHO, but the problem with it was that the VP it exported didn't work, whereas the one from VPMage did work. I probably did something wrong, but the strange thing was that the files looked exactly similar with VPView32 - that did manage to read the files. Oh well.
2. How do i save pictures in the right format to appear in the debriefing thing? Wing logos?
Don't need about the debriefing thing (*.ANI? something else?), but Wing logos are 256 colour PCX files with 128x128 resolution, and with a little specialty regarding transparency - pure green (00ff00) is regarded as transparent, so it kinda acts like one bit alpha channel. You can't blend into invisibility, though, because any other shades of green are not transparent.
So for example, this would result in the green section being transparent.

You will need a suitable image editor (for free, you can get GIMP which will do nicely for almost anything FS2_Open related) and then you'll need to make your image, then convert it to indexed colours, THEN you need to check that the indexing didn't change the transparent part into any shades of green, which can be a little bit of fiddling... and then you save the 256-colour indexed file as a PCX file, and it should work.
Same applies to avatars (or pilot images), but they are of different size.
3. How do i make stages in briefing?
No idea, since I've never been really into making missions, but I can point you to find Karajorma's FAQ and FREDding guides.
I have
of other questions, like how to time events and messages and warping in enemy shivans, but Is there an FAQ anywhere so that address all my questions there? Thanks in advanced!
Well, Karajorma's FAQ is good to read through, as well as his FREDding instructions, and then there's always the Hard Light Wiki.
