Out of scope question
i am making a mario clone in my class and i keep getting this error (11,52): error CS0029: Cannot implicitly convert type `UnityEngine.Vector3' to `float'
if anyone can help me out would be appreciated, does it mean you can't use a vector3 in this line of code? I wrote it out just like my teacher put it, but not sure why am getting the error - and of course I can't move on with the assignment without fixing this error - I have rewritten it many times just in case I missed something - but still get the error code.
thanks in advance
using UnityEngine; using System.Collections;
public class Camerafollow : MonoBehaviour {
public Transform target; public Transform leftBounds; public Transform rightBounds;
public float smoothDampTime = 0.15f; private float smoothDampVelocity = Vector3.zero;
private float camWidth, camHeight, levelMinX, levelMaxX;
// Use this for initialization void Start () {
camHeight = Camera.main.orthographicSize 2; camWidth = camHeight Camera.main.aspect;
float leftBoundsWidth = leftBounds.GetComponentInChildren ().bounds.size.x / 2; float rightBoundsWidth = rightBounds.GetComponentInChildren ().bounds.size.x / 2;
levelMinX = leftBounds.position.x + leftBoundsWidth + (camWidth / 2); levelMaxX = rightBounds.position.x - rightBoundsWidth - (camWidth / 2);
}
// Update is called once per frame void Update () {
if (target) {
float targetX = Mathf.Max (levelMinX, Mathf.Min (levelMaxX,target.position.x));
float x = Mathf.SmoothDamp(transform.position.x, targetX, ref smoothDampVelocity, smoothDampTime);
transform.position = new Vector3(x, transform.position.y, transform.position.z); } } }
here is a shorten version of my question -
this is the error I keep getting Assets/scripts/Camerafollow.cs(11,52): error CS0029: Cannot implicitly convert type UnityEngine.Vector3' to float'
for this line or code - private float smoothDampVelocity = Vector3.zero;
Doesn't that look weird to you :) ? float x = Vector3.something
Ask yourself this: what do you expect the value of some float to become when you try to put a Vector3 (consisting of 3 floats) into it ? I guess '0' in this case since the name of the Vector3 variable happens to be "zero", but just as well you could be doing
private float smoothDampVelocity = new Vector3(-3, 6, 10);
What would the float value become then ? -3, 6 or 10 .... or 10-3+6 ? And how could the compiler know ?
The compiler doesn't know how to make 1 float out of the Vector3 you are trying to put into it. If you want your float to be "0", just do private float smoothDampVelocity = 0f; Otherwise you have to do some more coding to tell the compiler what number to store in your float variable every time you assign a Vector3 into it.
There are strict rules for what types pf data you can store in different types of variables and what types can be converted to other types
I appreciate you answering my question - am still very new to scripting, I will try what you suggest and hope it works -
