How to setup an action to detect mouse click (placing object in world)?

What I want to do is when you press the left mouse button, something happens (place object). I don't want that thing to happen continuously, which is what I am experiencing.

I have an action setup for the left mouse button. Action type is "Button", interaction is "Press".

My code that runs:

Code (CSharp):

1. public void OnMouseLeft(InputAction.CallbackContext context){
2.     // Do something when pressed
3. }

I press the left mouse button, I want it to do 1 thing (i.e place an object in the world). Am confused on how to check for that. I tried "Tap" but that had the same issue. I looked at the properties of "context" but I am not sure which to use.

Edit: 0.9.3 is the version I am using

 

Thanks for replying.

I was hoping that I could set a bool in my class as I need to access it outside of my input manager.

Code (CSharp):

1. public void OnMouseLeft(InputAction.CallbackContext context){
2.     if(context.performed){
3.         this.mouseLeft = true;
4.     } else {
5.         this.mouseLeft = false;
6.     }
7. }

This doesn't work, am not sure on how to do this correctly.

Sorry.

 

It acts as if it's continuously held.

I guess what I am trying to achieve is exactly the behavior of

Input.GetMouseButtonDown

.

Following your sample code does work, so thanks for that.

 

@Rene-Damm Wait, wait, I have a question for this.

What do you mean by: // Put *after* PlayerInput so it gets enabled after it.
Do you mean to add this MyBehaviour-Component in the ComponentHierarchy of a GameObject AFTER the PlayerInput-Component? This implies that OnEnable gets called deterministic/hierarchical, that true or did I misunderstand that?

 

Alrighty then, I almost thought: holy S***, did you folks change something so fundamental and didn't tell anyone?

 

Gota question for you if you wouldn't mind taking a look at my script
I got these buttons i want to use the buttons to select a index of the character list

question is how would i update ....

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public partial class CharacterSeletion : MonoBehaviour
{
private GameObject[] characterList;
private int index;

private void Start()
{
index = PlayerPrefs.GetInt("CharacterSelected");

characterList = new GameObject[transform.childCount];

for (int i = 0; i < transform.childCount; i++)
characterList = transform.GetChild(i).gameObject;
foreach (GameObject go in characterList)
go.SetActive(false);

if (characterList[index])
characterList[index].SetActive(true);

}
public void ToggleLeft()

{

characterList[index].SetActive(false);

index--;
if (index < 0)
index = characterList.Length - 1;

characterList[index].SetActive(true);
}

public void ToggleRight()
{

{

characterList[index].SetActive(false);

index++;
if (index == characterList.Length)
index = 0;

characterList[index].SetActive(true);
}
}
public void SinglePlayerButton()
{
PlayerPrefs.SetInt("CharacterSelected", index);
SceneManager.LoadScene("Game");

}
public void MultiplePlayerButton()
{
PlayerPrefs.SetInt("CharacterSelected", index);
SceneManager.LoadScene("MultiplePlayer");

}
public void ToAnimalSelectionButton()
{
PlayerPrefs.SetInt("CharacterSelected", index);
SceneManager.LoadScene("AnimalSelection");

}
public void ToMainMenuButton()
{
PlayerPrefs.SetInt("CharacterSelected", index);
SceneManager.LoadScene("MainMenu");

}
}

To make it where instead of arrows being used its the buttons grabbing the indexes?

I figured that code for my animal selection now I wanna upgrade it some can you explain what part I have to change for it or do I need to rewrite it all? I just want the buttons to make one of the CharacterSelected object index to appear, so that'll be targeted and making it appear right? Still learning some here
