Hi all, would anyone happen to feel in a good enough mood to write me (what seems to me to be) a very simple cog? It's similar to Grismath's adventure camera cog, and it goes like this:

A cog runs from startup that sets the players' view point (this is multiplayer) to a predefined ghost position (with yaw, rol, etc. defined by me) looking down on the players. It IS NOT a cutscene however - the players (only two will be allowed in this mp level at one time) will be able to fight and run around, but the camera will remain stationary. Thanks, hopefully this is possible in Jedi Knight (NOT MotS)!

<nonessential but great if it is>
If someone could make it really cool and complicated, you could make it so that the camera followed the two players slightly in that it would:

1)pan out so that both of the two players were always in view of the camera.

2)zoom in the closer the players got to each other

3) follow the players short distances

</nonessential but great if it is>


Just to make it easier for people to realize what I'm talking about, I'll go ahead and state I'm envisioning some kind of Street Fighter/Tekken/Mortal Kombat type JK levels/mod.

I'd imagine that if you were able to keep it 2D, you could make the camera pan and such. Just put ghosts every X incriment and move the camera to another incriment based on the position and distance between the player. Positioning the camera so that it is appropriet for jumping and you've got it set. DBZtDiR had a camera EXACTLY how you're invisioning it, and it worked in all 3 Dimensions. It's highly laggy, too. Ask them to help you out, as I'm sure HR would be willing to rip it appart and hand it to you on a silver platter.

If I get some time, I'll look into it. It'll likely involve a lot of vector stuff and vector midpoints and junk for the advanced stuff.

I am not guaranteeing that I can turn anything up, however.

Thanks Slaw.

And Kirby, I haven't heard back from you on any of this stuff. Would you please tell me, by means of either the forums or Email, how to fix the DragonBall Z tDiR problem with messing up JK. Thanks, 'cuz I'd really like to be able to actually play the game again and get some editing done.

Also, I couldn't find the cog you mentioned. I ripped apart the various DBZ cogs, but couldn't find anything much to do with cameras (at least not in the title) and I'm quite frustrated. But since I can't edit or play JK at the moment anyway, it doesn't really make much difference. -_-
Sorry, not trying to rant, just a bit irritated and I'd apprecaite some help. Thankyou.

Some suggestions:
1. Reinstall TDir and uninstall it in disabled mode. Uninstall/reinstall JK afterwards.
2. Search your system for all files TDir related and delete them. Search your registry for all keys TDir related and delete them. Uninstall/Reinstall JK afterwards.
3. Backup your important data and kill your system. Use dark necromancy to revive it afterwards.

Zigabu's #1 is probably going to work the best.

Else you need to find a certain file *cjoku_g1h.c[/b]odugh* and delete it. It tricks JK, and is usually the problem.

Else you need to do Zig's idea.

Oh, and the cog is something like "ChallangeSetup.cog" or whatnot. It's probably got the camera cog in it, but I mentioned it simply because it's exactly what you're looking for. If you can manage to get DBZtDiR to work, I'd suggest you test it out. And really: Send Hell_Raiser an e-mail. He's a great guy, and would probably be willing to fix it up for your needs.

Okay. Good news... I got a basic camera going! It currently focuses on the midpoint between two players but without zoom in for close-up action.

I'll try to get that and the other stuff in there too. But you at least have the minimum (I think) now. [http://forums.massassi.net/html/smile.gif]

Okay, I'm having trouble getting the zoom in/out code to work correctly. If anyone else wants to take a crack at it go right ahead.

Here's the basic version. To work it, place a ghost at the position you want and set its pyr. Oh, forget the sector entering stuff; it will start the camera stuff on startup. Just define your playerthings and your ghostcam and you'll be ready to go. The view does follow the players, but the cam will stay stationary (as I haven't gotten it to zoom in/out correctly yet).

Code: 
# Jedi Knight Cog Script
#
# actioncam.cog
#
# This cog will require a ghost template for the camera.
# Dest0 and Dest1 are  the sectors which the players enter to be assigned
#  to the camera.

I will still attempt to figure this out, but any help would be perfect.

As promised, here are some levels to work with (only the first one loads thru JK -- I must've done something wrong in the Episode Editor [http://forums.massassi.net/html/rolleyes.gif] ; I haven't tried using debug to access the second level yet). The Jed files are included in the gob. Get it here. (If that link doesn't work, tell me and try here instead; please try the other link first though -- I want to see if it works for anything at all. Thanks).

it does zoom in and out as the players move together or apart.
to test it you can list the player1 thing as a walkplayer and player2 as something else.
if you want to try it with two players list both walkplayers as the player1 and player2.
until the second player joins the camera will be looking at the player1 person.
try it and see what you think.

That "lonely" killed message instructs JK to continue the scripting ("program") flow into the "newplayer" message block, because there's no "return" statement.

The upshot of it all is that by this way of doing things, you can force the "newplayer" message block to be executed when the "killed" message is called [http://forums.massassi.net/html/smile.gif]
