How to make filter with choose options

Unity Engine
1

Hello, i want to make an regular filter drop down picklist with options. But i dont have idea how to write it on C#. I kind of understand how to make it on UI.

So as you can see on my mockup - i have filters with options and filtering objects.

And just like in any filter functionality, only the Object should remain that matches the conditions / criteria. And if I delete the criteria, then other Objects should appear

I am currently not on my pc but I can write you some examples when I have access to it again. How ever what I can recommend you to do is to look at the current value of the dropdown and try to work with if/else or even add them together and then look for fitting criteria through switch/case.

As I said I can write you an exsample as soon as I have access to my computer so no exsample right now.

It would be nice, if you can help me, sir

Hi heres want I came up with:

using UintyEngine.UI;

//For the dropdowns that make up the final option
public class DropdownScript : MonoBehavior
{
//The Dropdown its attached to
Dropdown dropdown;
//To subtract the old value and add the new one to prevent the current Value of the button going off into infinty
int oldValue;
// List here all the option buttons you want to be affected
public OptionScript[] affectedButtons;

void Start()
{
  //Get the dropdown to read its current value
  dropdown = GetComponent<Dropdown>();
}

void Update()
{

 oldValue = dropdown.value;

 dropdown.onValueChanged.AddListener(delegate {DropdownValueChanged();});

}

void DropdownValueChanged()
{
 //Loop through all buttons that should get affected
 for(int i = 0; i < affectedButtons.Length; i++)
 {
  affectedButtons.currValue -= oldValue;
  affectedButtons.currValue += dropdown.value;
 }
}

}

using UnityEngine.UI;

//For the buttons that contain the Option availavble
public class OptionScript : MonoBehavior
{
public int currValue;
public int[] valuesToChangeOption;
//If you want to change the OnClick() function
public Button thisButton;

void Start()
{
  //thisButton = GetComponent<Button>();
}

void Update()
{
  switch(currValue)
  {
   case valuesToChangeOption[0]:
    //subscribe to the onClick event
    thisButton.onClick.AddListener(CustomButton_onClick);
    void CustomButton_onClick()
    {
     //Do stuff...
    }
    break;
  
    case valuesToChangeOption[1]:
     //subscribe to the onClick event
     thisButton.onClick.AddListener(CustomButton_onClick);
     void CustomButton_onClick()
     {
      //Do stuff...
     }
    break;

    //etc...
  }
}
}

This should do it I havn’t tried it out in unity but this should give each button a value on which you can put in your code to want to do when given value(currValue) is true
