How to find the x and y axis of a gameobject

Unity Engine
1

How can I find the x and y axis of a gameObject in script, so I can check whether the object is above or below a certain height? for example if the gameObject drops below 100 meters, it triggers something.

any help or advice would be great

thanks in advance

if (transform.position.y <= 100) {
//Do stuff
}

Thatā€™ll work for both C# and ā€œJavaScriptā€/UnityScript.

This is very basic stuff; Iā€™d recommend some tutorials before you go much further into Unity.

thank you

I do when I can find them, most are just repeats of others.

I think you could use a custom c# function like this:
public float getXAxis(){
return transform.position.x;
}

and then call it whenever you needed.

This worked in previous games I worked on but now I use it and this is the error I get:

error CS1612: Cannot modify the return value of ā€˜Transform.positionā€™ because it is not a variable

This is my code:

using UnityEngine;

public class RandomizeMissleSpawns : MonoBehaviour
{
    // Update is called once per frame
    void Update()
    {
        transform.position.x = Random.Range(-11, 12);
        Debug.Log(transform.position.x);
    }
}

You have to replace the whole position vector at once:

transform.position = new Vector3(
  Random.Range(-11, 12),
  transform.position.y,
  transform.position.z);

That being said, the position of this thing is going to jump around like crazy every frame!

It works! Thank you! and just so you know, I wanted it to go like crazy because I was moving a object to determine Missle Spawning. I also learned how to give a value to a Vector3 in code! Thanks!

Great to hear it!

By the way, I find myself doing similar things with Vectors often enough that I wrote some simple extension methods that let you quickly get a Vector3 that is the same as some other Vector3, but with one dimension that is different:

        public static Vector3 WithX(this Vector3 vector, float x) {
            return new Vector3(x, vector.y, vector.z);
        }

        public static Vector3 WithY(this Vector3 vector, float y) {
            return new Vector3(vector.x, y, vector.z);
        }

        public static Vector3 WithZ(this Vector3 vector, float z) {
            return new Vector3(vector.x, vector.y, z);
        }

With these extensions your code could be a little simpler:transform.position = transform.position.WithX(Random.Range(-11, 12));

sorry me dont do that big boi stuff im too new i just yeeted from scratch lol But thanks for the suggestion!

Iā€™m here because I need to know the position of a different GameObject through the script of a certain one. Example:

I want to access the cameraā€™s coordinates through a script on a cube.

What built-in variable accesses that?

im yeeted from scratch too lol (moving on to roblox or unityā€¦ im picking)

Please stop necroing old posts. Create your own thread, ask your own question there.

Thanks.
