Moving the camera "on rails"
Hi guys I'm making a point and click adventure game with unity, and I'm trying to set the environment to be "semi" realtime. What I mean is, I want the camera to move only when the mouse is clicked on specific areas in the scene. I tried to do it with animation, but the results were less than expected. What I want to do is move the camera with code, but I'm not sure how to do it. I managed to create a script which "teleports" the camera to the area I clicked, but can't manage to make it move there smoothly. Thanks in advance.
Well, you could just simply modify the transform.position of the camera over time. Also using functions like Lerp or SmoothDamp could make that more easy.
I assume your code changes the transform.position of your camera to the new desiredPosition, like that
transform.position = desiredPosition
What you could do instead, is to linearly interpolate between the two vectors over time
function Update(){
transform.position Vector3.Lerp (transform.position,desiredPosition
Time.deltaTime * timeInSeconds);
}
This will gradually move your camera over time, so it gets to the desiredPosition (wich has to be a vector3) in the time of timeInSeconds (which should be a float)
If you can manage a teleport, you can manage a smooth transition.
Teleport script:
void PortToPosition(Vector3 targetPos)
{
transform.position = targetPos;
}
Call this like so:
PortToPosition(place to go to);
If you want it to move smoothly, replace it with this function:
IEnumerator SlideToPosition(Vector3 targetPos, float time)
{
// Use an animation curve to make it look sweet!
AnimationCurve smoothly = AnimationCurve.EaseInOut(0, 0, 1, 1);
Transform myTrans = transform; // cache the transform for extra efficiency!
float curTime = 0;
Vector3 startPosition = myTrans.position;
while(curTime < time)
{
myTrans.position = Vector3.Lerp(startPosition, targetPos, smoothly.Evaluate(curTime / time));
curTime += Time.deltaTime;
yield return null;
}
myTrans.position = targetPos;
}
Call it like this:
StartCoroutine(SlideToPosition(place to go, time to take));
Adapting this to manage rotation as well is pretty straightforward.
