I have a coroutine that moves my Camera upwards each time the player reaches a certain point in the game. I used a coroutine so that the camera will move smoothly over time.
Here’s a snippet of my code:
private IEnumerator MoveCameraUpCoroutine(Vector3 startPos, Vector3 endPos, float duration)
{
float elapsedTime = 0;
while(elapsedTime < duration)
{
transform.position = Vector3.Lerp(startPos, endPos, (elapsedTime/duration));
elapsedTime += Time.deltaTime;
yield return null;
}
}
public void MoveCameraUp(Vector3 startPos, Vector3 endPos, float duration)
{
StartCoroutine(MoveCameraUpCoroutine(startPos, endPos, duration));
}
In my controller script, I just call my coroutine like this:
cam.GetComponent<CameraMovement>().MoveCameraUp(cam.transform.position,
new Vector3(cam.transform.position.x, cam.transform.position.y + setupLevel.heightOfBlock, cam.transform.position.z),
0.1f);
The problem with this is that the camera’s movement is not always consistent in terms of where it’s supposed to stop. I did some debugging. On the first run, the camera moved to the 0.7864508 yPos. On the second run, the camera moved to the 0.7789915 yPos. etc. It’s not consistent.
But when I simply use Translate instead of my coroutine:
cam.transform.Translate(0, setupLevel.heightOfBlock, 0);
I get consistent end values for the camera’s yPos at 0.7876318, which is what I need. But this code does not move the camera smoothly over time which is not what I want. It makes the camera teleport from pointA to pointB instead of moving it over time.
Does anyone know how to fix this coroutine issue? I don’t know but I think there’s something wrong with my coroutine code. Any help is greatly appreciated.
