Move along grid where facing
I've been trying to make a dungeon crawler, like Legend of Grimrock, and I can't get the movement right. I can't even get "snapping" movement right. Is there a way I can add 1 to the x or y (depends on where you're looking)? Or even better, slowly move the camera until it has added 1 to the vector. Here is my try...
function Update () {
if(Input.GetKeyDown(KeyCode.W)){
transform.localPosition.z += 1;
}
if(Input.GetKeyDown(KeyCode.A)){
transform.Rotate(0,-90,0);
}
if(Input.GetKeyDown(KeyCode.S)){
transform.localPosition.z -=1;
}
if(Input.GetKeyDown(KeyCode.D)){
transform.Rotate(0,90,0);
}
}
As you can see, I have only managed to snap angles, and snap only to one vector. Help?

If you want to move one unit forward you can do:
transform.position += transform.forward;
This will move the camera forward one unit since transform.forward is normalized (i.e. one unit long). To move backwards:
transform.position -= transform.forward;
As for moving it over time, that is more complicated. Look at Vector3.Lerp() and Vector3.MoveTowards() for two functions that move things over time.
