how to communicate with the target gameobject?

Questions & Answers

I am trying my camera to follow a 2d player only on x position but c# is very strict

this is the script of my camera

public class Follow : MonoBehaviour {
	public Transform target;


	
	// Update is called once per frame
	void Update () {
		transform.position.x = target.position.x;
	}
}

I dont know the data type to make store them as a variable, I tried vector but it cant be explicitly convert from float? an explanation as to why this code won’t work and why your code would work is a big help. thank you

Transform.position is a Vector3, and C# is a stickler about how you modify an a single component of transform.position. You can do it this way:

void Update () {
    Vector3 pos = transform.position;
    pos.x = target.position.x;
    transform.position = pos;
}
3

void Update () {
Vector3 pos = transform.position;
pos.x = target.position.x;
transform.position.x = pos;
}

I dont know why but this did not work, I got 2 errors

Assets/Follow.cs(13,27): error CS1612: Cannot modify a value type return value of `UnityEngine.Transform.position’. Consider storing the value in a temporary variable

and
