Spaceship orientation problem

[murga]

Hi all,

Because this is my first post i need to say that you guys doing wonderfull job here with this engine.
Second on to my problem:
I'm having diffculties with Spaceship orientation in 3D. I have implemented basic selection box (Selection box tutorial). Using right mouse button i need to move my spaceship to that destination. having ship position and using viewport.unproject how can i calculate facing vector and movement of my ship?

Thnx in advance.

So you are drawing a 2D box on the screen and want to move a 3D object there.

First of all your 2D box does not have any depth so you will have to decide how far this will be (unless you want to move to an object in the box)
Now you have a depth (either chosen or taken from an object in the box) you need to get the vector to move to, a target vector, you can do this with the ray picking code using the center of the box as the mouse x,y and the depth selected above as the end point, the unproject of these will give you the 3D X and Y and use your depth value for the Z.

To rotate your ship to point at the target coord, use the LookAt method that mike put in is last Camera tutorial, then move your object to the target.

Not tried any of that, but it sounds like it might work

It's not exactly 2D box where 3D object have to move, but a point. That point is calculated using ray picking code with some depth value when user press right mouse button on certain location.
Anyway thank's for pointing out for that LookAt code i'll see what can i do.
Stay tuned

btw. sorry for my english
