How do you call a function once

Question

So I Created a function that runs with

     void OnTriggerEnter(Collider other)
 {
 if (other.gameObject.CompareTag ("Ocean"))
             {
                 SceneManager.LoadScene("minigame", LoadSceneMode.Additive);
             }        
 }

The problem is it collides about 4 times before the seen is actually loaded, so then the scenes get stacked on top of each other and all run at the same time. I am new to unity and don't know how to fix this. Please help. Once I get this done I will almost have my game finished, so thank you for your help. @SohailBukhari

use boolean

 private bool loadSceneCalled = false;
 
 void OnTriggerEnter(Collider other)
  {
 
 if(loadSceneCalled)
      return;
 
  if (other.gameObject.CompareTag ("Ocean"))
              {
                  SceneManager.LoadScene("minigame", LoadSceneMode.Additive);
                  loadSceneCalled = true;
              }        
  }

Alright, that worked, but I still have a problem. It doesn't close the already open scene, so I still have two running at the same time, the current scene and the old one. How do I fix that? Btw, The answer was beautiful thanks @walaoRIKI

oh...you just change the LoadScene$$anonymous$$ode.Additive to LoadScene$$anonymous$$ode.Single

Or juz call the load scene function like this

 Scene$$anonymous$$anager.LoadScene("$$anonymous$$igame");

This still will not work. I need to be able to close the current scene and then run the Scene$$anonymous$$anager.LoadScene("$$anonymous$$igame");

In that order. Thanks

If I do that should I keep the boolean or not? Also, How do you close a scene? Thanks

$$anonymous$$aybe you can switch to a blank or black scene or I call it a loading scene first and then only switch to the scene you want

If I do that should I keep the boolean or not? Also, How do you close a scene? Thanks

If you switch to another scene then only switch to $$anonymous$$i game scene then no need the boolean. Usually before I switch the scene I will turn on a black panel with Loading text from UI canvas first then only call the LoadScene function, if I want to have some fancy loading animation then I will use loadsceneasync to load the on blackground.
