Hi
I've been playing around with adding swimming + diving to a 3rd person game and it seems that EVERY f***ing time make any thing on it something else is getting in the way. So i trashed all my code now to try start on a fresh but im really lost in what i should do and there for turning to the forum here.
most of you are most likely known to wow and how you swim in there and its something like that i wanna have but there is a lot there is lots of other problems im running into.
the swimming should be a little like this: [URL="http://forum.unity3d.com/threads/121494-Released-WoW-Character-Movement-Camera"]http://forum.unity3d.com/threads/121494-Released-WoW-Character-Movement-Camera[/URL] but i really don't feel like using money on that package (i'm broke) and i do not know if this have all my requirements.
I've made this drawing in boredom to show the concerns and problems I've been running into: [URL="https://www.dropbox.com/s/nq75tfd753fq17r/swimming-lol.png"]https://www.dropbox.com/s/nq75tfd753fq17r/swimming-lol.png[/URL] (please look at it and you'll get the idea)
The requirements is:
no gravity while diving AND swim the way the camera is facing
gravity should apply if you're in places like underwater caverns
swimming in the water surface that then goes into diving if the camera is facing down (like in the old counter strike maps that had water in them)
then hitting the buttom you should not be able to move into walking/isgrounded but keep on swimming/diving
i really need to sample codes to this since I've been stared blankly into my own crap and looked all over Google for at least 2 weeks without progress so pretty please - samples and/or explanations!
for moving my character at this point i'm using a slightly modified charactermotor script remade and change into C#, and for camera movement i'm using a FPS/freelook script (sources below) since it should work a little like GTA.
I would really prefer to add swimming/diving to the charactermotor so but i'm willing at this point to redo the most of the character movement system to be able to add a proper swim/dive system.
So if there is any suggestions please post them for the love of angry code blocks! and feel free to add to/modify my script here below if you think you can help me add some useful code.
Thanks A LOT in advance and deep respect!
- Jackie
