Movement system for 3d space shooter

Hello,
I created simple 2d space shooter where my object only move along x and z axis and rotate along Y axis towards mouse cursor(I used LookAtMouse script in C# from wiki).

But right now Im thinking about creating 3d space shooter, where my ship can move in 3d space environment, like in those games:
- http://www.youtube.com/watch?v=7V_qXyNKHgc
or
-http://www.youtube.com/watch?v=nQpOgAA21oE (this is better I think)

But I dont know where to start unfortunately... Do you know anything that could help me? Or I need to buy some projects in Asset Store and look at source code?

 

There are a many free scripts on the web, also free projects to get your hands on. For anyone new to Unity it's a good idea to just download everything Unity. All tutorials, scripts and other resources. Then go through the tutorials to see how things work. This builds a nice library of scripts to reference from in the future.

Space games don't have gravity ( most the time lol) so a rigidbody with its gravity turned off and the use of rigidbody add force is one way to go. Then all you need is the smooth camera script that comes with Unity.

 

You can play whit this script , i use it a lot in most occasions. Hope help you.

123.     GUI.Label(Rect(10,30,200,50),"Vidas: " + vidas);    
124. }
125. @script ExecuteInEditMode()

 

This script is not written in english lol :E...


Also, even if I will use rigibody, how Can I rotate my ship with camera. Is there any tutorial for that?
I mean that I wanna do something like that my ship will follow my camera and rotate with my mouse?

For example:
I press "W" key so my ship is start moving ahead, then I use my mouse to rotate my ship so he can get to the higher point.

 

Hey Zoboleq, I'd suggest using the "Space Game Starter Kit" It is really easy if you are willing to look through the code. Completely modular and very simple to add new modules for. It is on the asset store by a group called Tasharen, same mob who made the NGUI. Helped me out a lot.

 

I saw that once, but it is to expensive for me and I think that I prefer self-learning method through tutorials. Unfortunately there is lack of this kind tutorials...
