Camera.rect lerp not working
hi I trying to animate the camera normalised viewport rectangle on the click of a button but it moves without regarding the lerp function i have put in there here is the code:
using UnityEngine;
using System.Collections;
public class moveCam : MonoBehaviour {
public float open;
public float closed;
void OnClick ()
{
Camera.main.rect = new Rect (0, 0, Mathf.Lerp (open, closed, Time.time), 1f);
}
}
Any help is greatly appreciated thanks
Please post comments as comments, not as new answers.
you are only calling this for one frame, so it will jump to the precise size determined by that exact Time.time..
first, have a look here:
http://docs.unity3d.com/Documentation/ScriptReference/Mathf.Lerp.html
in the example, in the update function, we are returning a slightly different value each frame for "Time.time". since it is called every frame, the effect is animated over time.. There are plenty of ways to accomplish what you want..
here's one:
float stepper = 0.0f;
bool clicked = true;
float speed = .01f;
void Update ()
{
if(clicked && stepper < open){
Camera.main.rect = new Rect (0, 0, Mathf.Lerp (open, closed, stepper), 1f);
stepper+= speed;
}
else if(!clicked && stepper > closed){
Camera.main.rect = new Rect (0, 0, Mathf.Lerp (closed, open, stepper), 1f);
stepper-= speed;
}
if(Input.GetMouseButtonDown(0))
clicked = !clicked;
}
just an example

am just writing in the lerp not using mathf, but it works, and as a function .
Rect LerpRect(Rect nRect1, Rect nRect2,float nNum){
Rect vRect=nRect1;
vRect.x+=(nRect2.x-nRect1.x)*nNum;
vRect.y+=(nRect2.y-nRect1.y)*nNum;
vRect.width+=(nRect2.width-nRect1.width)*nNum;
vRect.height+=(nRect2.height-nRect1.height)*nNum;
return(vRect);
}
