I need a code that move camera field of view (FOV) between a min and max value like 50-70 to zoom in and zoom out the camera view
For that i tried Mathf.MoveTowards function and it works well :
GetComponent<Camera>().fieldOfView = Mathf.MoveTowards(camFOV,maxFOV,speed*Time.deltaTime)
Now i need this to run like that :
1)First wait 2 to 5 seconds
2)Zoom in (decrease fov to minFOV)
3)Wait 1 to 3 seconds randomly
4)Zoom out (increase fov to maxFOV)
5)REAPET THIS PROCESS UNTIL GAME RUNS
Please help me!
Thanks.
This type of “do X, wait, do Y, wait” problem is a great use for Coroutines. In your specific case, it would look something like:
<code>IEnumerator ChangeCameraFOV(Camera camera) {
while (true) { // Or until some condition
// Wait 2-5 seconds (random)
yield return new WaitForSeconds(Random.Range(2f, 5f));
// Zoom in
while (camera.fieldOfView > minFOV) {
camera.fieldOfView = Mathf.MoveTowards(camera.fieldOfView, minFOV, speed * Time.deltaTime);
yield return null; // Wait for next frame
}
// Wait 1-3 seconds (random)
yield return new WaitForSeconds(Random.Range(1f, 3f));
// Zoom out
while (camera.fieldOfView < maxFOV) {
camera.fieldOfView = Mathf.MoveTowards(camera.fieldOfView, maxFOV, speed * Time.deltaTime);
yield return null; // Wait for next frame
}
}
}
</code>
<code>IEnumerator ChangeCameraFOV(Camera camera) {
while (true) { // Or until some condition
// Wait 2-5 seconds (random)
yield return new WaitForSeconds(Random.Range(2f, 5f));
// Zoom in
while (camera.fieldOfView > minFOV) {
camera.fieldOfView = Mathf.MoveTowards(camera.fieldOfView, minFOV, speed * Time.deltaTime);
yield return null; // Wait for next frame
}
// Wait 1-3 seconds (random)
yield return new WaitForSeconds(Random.Range(1f, 3f));
// Zoom out
while (camera.fieldOfView < maxFOV) {
camera.fieldOfView = Mathf.MoveTowards(camera.fieldOfView, maxFOV, speed * Time.deltaTime);
yield return null; // Wait for next frame
}
}
}
</code>
IEnumerator ChangeCameraFOV(Camera camera) {
while (true) { // Or until some condition
// Wait 2-5 seconds (random)
yield return new WaitForSeconds(Random.Range(2f, 5f));
// Zoom in
while (camera.fieldOfView > minFOV) {
camera.fieldOfView = Mathf.MoveTowards(camera.fieldOfView, minFOV, speed * Time.deltaTime);
yield return null; // Wait for next frame
}
// Wait 1-3 seconds (random)
yield return new WaitForSeconds(Random.Range(1f, 3f));
// Zoom out
while (camera.fieldOfView < maxFOV) {
camera.fieldOfView = Mathf.MoveTowards(camera.fieldOfView, maxFOV, speed * Time.deltaTime);
yield return null; // Wait for next frame
}
}
}
And then start the coroutine with StartCoroutine:
<code>Corotuine cameraChangeCoroutine;
public void Start() {
cameraChangeCoroutine = StartCoroutine(ChangeCameraFOV(GetComponent<Camera>()));
}
</code>
<code>Corotuine cameraChangeCoroutine;
public void Start() {
cameraChangeCoroutine = StartCoroutine(ChangeCameraFOV(GetComponent<Camera>()));
}
</code>
Corotuine cameraChangeCoroutine;
public void Start() {
cameraChangeCoroutine = StartCoroutine(ChangeCameraFOV(GetComponent<Camera>()));
}
And stop it with StopCoroutine:
<code>StopCoroutine(cameraChangeCoroutine);
</code>
<code>StopCoroutine(cameraChangeCoroutine);
</code>
StopCoroutine(cameraChangeCoroutine);
