Using sliders to control X and Z of an object

Questions & Answers
1

I’m trying to control an objects X and Z using 2 sliders (1 for each value).
It worked fine using the script for X, but when using the script for Z nothing happens. Both are applied to the object and both “AdjustWidth” and “AdjustHeight” are added to the slider value.

Code for X:

  using UnityEngine;
  using System.Collections;
  public class Gulv_bredde : MonoBehaviour
  {

    // Use this for initialization
    public float gulvBredde = 1f;
    void Start()
    {

    }
    public void AdjustWidth(float nyBredde)
    {
        gulvBredde = nyBredde;
    }
    // Update is called once per frame
    void Update()
    {
        transform.localScale = new Vector3(1f+gulvBredde, 0.25f, 1f);
    }

}

Code for Y:

  using UnityEngine;
  using System.Collections;
  public class GulvLengde : MonoBehaviour
  {

    // Use this for initialization
    public float gulvLengde = 1f;
    void Start()
    {

    }
    public void AdjustHeight(float nyLengde)
    {
        gulvLengde = nyLengde;
    }
    // Update is called once per frame
    void Update()
    {
        transform.localScale = new Vector3(1f, 0.25f, 1f+gulvLengde);
    }

}

Any help is appreciated!

I changed the code to this and it now works :slight_smile:

        Z:
        Vector3 scale = transform.localScale;
        scale.z = gulvLengde;
        transform.localScale = scale;

        X:
        Vector3 scale = transform.localScale;
        scale.x = gulvBredde;
        transform.localScale = scale;

Note 1: use English in your code, it’ll make your life easier. trust me.
Note 2: Your approach is really bad, you should avoid calling Update() function if it’s not necessary.
Note 3: You’re trying to do 2 things every frames:

 transform.localScale = new Vector3(1f, 0.25f, 1f+gulvLengde);

and

 transform.localScale = new Vector3(1f+gulvBredde, 0.25f, 1f);

First operation sets your object’s scale to, let’s say (1,0.25,1.53) (Z value dependent on slider value)
Second operation takes this rescaled object and it rescales it again - in this point, it sets Z scale back to 1 - so the output scale is (1+sliderValue,0.25,1). You need to have it this way:

float xScale, zScale;
Transform objectToResize;
public void RescaleX(float sliderValue)
{
    xScale = sliderValue;
    ResizeObject();
}
public void RescaleZ(float sliderValue)
{
    zScale= sliderValue;
    ResizeObject();
}
void ResizeObject()
{
    objectToResize.localScale = new Vector3(xScale, 0.25f, zScale);
}

Assign RescaleX and RescaleZ to your sliders, and it’s done.
