How to stop the camera in a certain position?
Hello to everyone!
I've made a code where camera starts to move on press button and in a certain position (currentpos.z > 13f) it appeared in another place and continue moving. Now I need to make it stop in the coordinates where z is equal to 0. And it is not working. As I understand, the last if should be somewhere else or I should include an additional parameter.
Could anyone help with this? Thank you!!!
THE CODE::
using UnityEngine; using System.Collections;
public class Navigation : MonoBehaviour {
bool moveCam = false;
bool waitActive = false;
GenerateRoom updateRoom;
void Start () {
updateRoom = GameObject.Find("MainRoom").GetComponent("GenerateRoom") as GenerateRoom;
}
void Update () {
if (Input.GetKeyDown (KeyCode.UpArrow)) {
moveCam = true;
}
if (moveCam == true) {
Vector3 currentpos = Camera.mainCamera.transform.localPosition;
if (currentpos.z > 13f) {
Debug.Log ("true");
Camera.mainCamera.transform.localPosition = new Vector3 (0f, 5f, -10f);
updateRoom.DestroyObjects ();
updateRoom.CreateObjects ();
updateRoom.ChangeTexture ();
}
currentpos.z += 0.06f;
Camera.mainCamera.transform.localPosition = currentpos;
if (currentpos.z == 0)
moveCam = false;
}
}
}

Your problem is with floating point number accuracy. The z value might be -0.04 one frame, and then 0.02 the next (since you're adding 0.06 each frame), and so will never equal exactly 0.0.
Change the "if" to this:
if (currentpos.z >= 0.0f)
{
currentpos.z = 0.0f;
moveCam = false;
}
and it should work fine.
In general, doing == comparisons on floats is a bad idea almost all of the time.
