Unity OneMouseDown second Object-CodePudding

I'm a begginner in Unity.

I have a script, which arrange the movement of two game object. I use onm ouseDown. It activates the GameObject where the click happened and let the movement (with keyboard). My problem is if I click the second game object the first one still moves (both of them). How can I turn off the movement for the first object?

 void onm ouseDown()
    {
      
      if (activeUnit==false ) 
      {
        activeUnit=true;
                      
        }
      else {activeUnit = false;}
    }


    void Movement (){

        if (activeUnit == true)
         {//here comes the movement method

Thank you for your help!

If you want to limit the movement to exactly one object you could use a static instead your bool and go

private static YOURCLASS _currentlyActiveInstance;

void onm ouseDown()
{
    if(_currentlyActiveInstance == this)
    {
        _currentlyActiveInstance = null;
    }
    else
    {
        _currentlyActiveInstance = this;
    }
}

void Movement ()
{
    if (_currentlyActiveInstance == this)
    {
        //here comes the movement method  
    }
}

To toggle a variable first you should better use this syntax:

void onm ouseDown()
    {
      activeUnit=!activeUnit;
    }

You can add another function onm ouseUp to Untoggle the unit. So the full code should look like that:

void onm ouseDown() {
      ToggleUnit();
}
void onm ouseUp() {
      ToggleUnit();
}
void ToggleUnit() {
   activeUnit=!activeUnit;
}

Otherwise if you don't wanna use onm ouseUp to untoggle the Unit, you should add an EventListener that untoggle units when clicking
