Click Objects In Unity - How To Click Objects in Unity 5 | Unity Mouse Tutorial

[@gianmarcopane2806]

If someone has trouble in detecting objects, check if the object has a collider on it :)

[@theloafdude8304]

Thanks dude. Saved my life there

[@gianmarcopane2806]

Pigster glad to help :)

[@CHRISTAMOSPAGHETTIO]

Hi there, my objects have colliders but I still have trouble detecting objects: NullReferenceException: Object reference not set to an instance of an object PlayerInteract.Update () (at Assets/PlayerInteract.cs:12)

[@gianmarcopane2806]

CHRISTAMO SPAGHETTIO there’s no playerInteract script in this tutorial, usually you got this error when you trying to do “something” with an object which is actually null. If you need further help add me on Facebook, I can help you there :)

[@廖奕新-k5i]

2020.11.06 If someone has trouble in detecting objects that "have" collider, check if your camera's tag is "MainCamera" T_T

[@anothermonkeyplaying4773]

If someone is trying to do it with sprites, try this: if (Input.GetMouseButtonUp(0)) { RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero); if (hit.collider != null) { Debug.Log("Target Name: " + hit.collider.gameObject.name); } }

please someone halp me, why does it not work on UI text? it has a box collider 2D and a square works with this but not UI text. I'm desperate for answers

[@Abiodapro]

You saved me! Thanks a lot!

[@ryandonaldson3370]

I get NullReferenceException: Object Reference not set to an instance of the object. Every time I click this pops up in the console.

[@lordsubl1me]

good tuto, actually explained everything

[@christopherarendt3531]

More clear to me: Rigidbody rb = hit.transform.GetComponent(); if(rb) ... You have = in if, which I know sets it and tests the result at the same time, but it is easily overlooked, since usually you use == in conditions.

[@buddyroach]

7:18 how you do a condition without using double equal sign?

[@mariatikhomirova7990]

great video, exactly what I was looking for

[@Hugo.Digital]

Amazing help to my projects. Thx.

[@flaviopitica]

great explanation, thanks! keep up the amazing job

[@viktorhyper]

Nice tutorial dude! Thx a lot!

[@andrescarretero3542]

If it doesn't work to anyone try this adding this: Camera cam; void Start(){ cam = GetComponent(); } and then in the method Update, replace 'Camera.main' with cam

[@meatburger6910]

Andres Carretero Thanks so much.

FIANLLY A GOOD TUTORIAL ON THIS

[@DonnyPhan-v7h]

Hi, I was wondering how you were able to detect the Ground Click? Did you include a collider?

[@jthrash841]

Thanks. Just what I needed.

[@SamCo99]

Awesome vid, thanks so much! Any words of advice on if I want text to display in game when the player clicks on something? Pretty new to Unity and kinda struggling a bit, but basically I want a text box to appear when the player clicks on something (the camera is first person too). Either way, thanks a bunch!

[@kinshuksinghbist7571]

Hey!Cool video!!! i don't have money but i wanna support you...Well I saw the whole add and clicked on it!!Keep Up!

Hi. But you're not telling how to prepare game object. what components should be added to the gameobject.

[@waffwrw]

Thank you sooooooo much bro! ily

[@Emre-db1kj]

Thanks for the video! How do you get the recommendations of methods if you type in for example "Input."? Do I have to install some kind of an extension?

[@wahyuzulyasyaputra6786]

Thanks. Helpfully..

[@rayjunior3204]

how would you make the ball move to another location in a certain area ??? (so when mouse is clicked the ball should move in a random place between x(400) and y(400))

AWESOME, thanks!

brilliant. thank you

Thanks!

[@linushallgren4156]

I had pretty much the same code yet id did not work before watching the video and the issue was how far the rays went :(. This video still helped me solve it but so frustrating that something so simple had made me waste half an hour

[@Jacktherippler1]

hey mate, i created my own hextile in blender. now i added a box collider to the hex and its working. but i got 10000 tiles and dont want to add it to every single one. i cant make copies of the one hex with the boxcollider. any other ideas? thank you so much! awesome example!good job

[@ImprovedTruth]

In case you didn't figure this out, after you create an object in code: hextile.AddComponent();

[@Jacktherippler1]

@@ImprovedTruth thanks mate! I iterate over every tile and did every joob you said!

[@Jacktherippler1]

@@ImprovedTruth thanks a lot!!!

[@woshstudios]

This was super helpful, how do you combine this selection with say a click to move along a navmesh?

[@louisdaisomont490]

I had an error because i changed my camera, so the Camera.main.ScreenPointToRay(Input.mousePosition) wasn't working because my camera hadn't the tag MainCamera Take care to that if you are in the same case as me

[@ceb1ueseamcbride220]

When I tried to use the code at 5:40 it says, "cannot convert from 'string' to 'UnityEngine.GameObject'" I am not sure what's wrong here's my code I am also using 2d 2021.3.5f1 using System.Collections; using System.Collections.Generic; using UnityEngine; public class ObjectClickerScript : MonoBehaviour { private void Update() { if (Input.GetMouseButtonDown(0)) { RaycastHit hit; Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); if (Physics.Raycast(ray, out hit, 100.0f)) { if (hit.transform != null) { PrintName(hit.transform.gameObject); } } } } private void PrintName(GameObject go) { PrintName(go.name); } }

[@fabianhofmann9356]

My brain has a melt down.

[@JustJory]

its freezing for me because i am pausing trying to think all the time

[@sagargada73]

This script works with normal object, but when i import my model eg. a building, it does not detect my model, if anyone knows how to achieve that drop a comment! help me out!

[@blaiseflorendo3967]

does it work with mobile inputs too?

[@itanitv]

Blaise Florendo Yup, but you would have to use the Input.touches array for a screen point rather than the mouse position, and check if the touches arra's length is greater than zero

[@blaiseflorendo3967]

Xenfinity Okay. Thanks!

[@jswerve6823]

My raycast hits my canvas before it can hit an object. how do I ignore this case?

[@itanitv]

I'll recommend using a layermask for everything except whatever you don't want to hit. So for example your Canvas probably has the layer "UI." So you'll want to get a reference to the layermask of that layer like so: var mask = LayerMask.NameToLayer("UI") Then you can use the Physics.Raycast definition to pass a layermask of everything that is NOT the UI mask using the ~ operator. For example: Physics.Raycast(position, direction, out hit, Mathf.Infinity, ~mask)) Let me know if you need any more help!

[@StaryzHelios]

how about 2d?

[@itanitv]

You would likely want to use Physics2d.raycast instead!

[@CirbyWeh]

@@itanitv I tried this in my 2D project and it works fine, with a big but: When I have two overlapping colliders, it only detects the object closer to the camera (Z position). Changing the Sorting Layer or Order in Layer does only change the visual appearance. So worst case scenario: ObjectA is visually completely hidden behind ObjectB, but I can only click on ObjectA. Do you have an idea how to fix this, without changing the Z positions?

[@general_md]

Use "void onMouseDown()", it detects the click on an object with a collider on it as "is trigger"

[@wuimingleebarroga8629]

if i have 2 object with different movement when clicked, how can i do that?

[@itanitv]

You could create another script with different behavior! Or you could have a a serialized or public field and change it in the inspector for each game object

[@wuimingleebarroga8629]

@@itanitv thanks

[@itanitv]

No problem! Let me know if you still have any questions

[@GEORGE.M.M]

Hey Great tutorial!! quick question, how would I select and object using the raycast I'm operating using the xbox controller, instead of a mouse? RaycastHit hit; float theDistance; //Debug Raycast in the Editor - SO WE CAN SEE IT! - MAKES LIFE EASIER! //Vector3 forward = transform.TransformDirection(Vector3.forward) * 10; Vector3 back = new Vector3(Input.GetAxis("XBOX.1.RightStick.X") * Time.deltaTime * 10, Input.GetAxis("XBOX.1.LT") * Time.deltaTime * 10, Input.GetAxis("XBOX.1.RightStick.Y") * Time.deltaTime * 10); Debug.DrawRay(transform.position, back, Color.green); if (Physics.Raycast(transform.position, (back), out hit)) { if (hit.collider.gameObject.tag == "tile") { theDistance = hit.distance; print(theDistance + " " + hit.collider.gameObject.name); if (Input.GetButton("XBOX.1.RightStick.Press")) { Cube.Selected = this.gameObject; } } } I created a separate class called raycastFoward, and the item I want to select is a class called Cube. I end up selecting the drawn ray, Im trying to select a game of object from another class instead, is this the wrong way to pass the argument, plus my script is attached to a game object child of my main camera.

[@GenoFelice]

Why not use OnMouseEnter instead of a ray. What is the advantage?

[@itanitv]

More control. You could use the function "OnMouseClick," but it makes a lot of assumptions and forces you to do everything only in that function's context. For example, you may want to only click within a certain distance before the clicked object is retrieved (raycast with distance vs click, then distance check)

[@GenoFelice]

Makes sense

[@sode07]

ScreenPointToRay is not clear to a beginer it basically makes a screen point in to a ray xD I laughed so hard

[@Aresvfxx]

Can i use this in a 2d game?

i am trying but it is not working for me

why was your audio so scuffed lol

[@giorgiamashukeli941]

[@itanitv]

Which line are you getting that on? Does your target have a collider and rigidbody?

[@CHRISTAMOSPAGHETTIO]

@@itanitv Hi, I have the same issue, I have tried turning collider/rigidbody on and off but I still get this same issue: NullReferenceException: Object reference not set to an instance of an object PlayerInteract.Update () (at Assets/PlayerInteract.cs:12)

[@CHRISTAMOSPAGHETTIO]

Somehow, changing the 'player' tag from my main camera to 'main camera' has it working, thanks for the tutorial! XD

[@itanitv]

Yeah that's why Camera.main is not a great field to reference. It's actually a property rather than an attribute so it's not a constant time access. It actually searches the entire hierarchy of game objects in you scene to find a camera tagged "MainCamera." It's a poor system and gets slower as you add more game objects to a scene, but it works for tutorials to avoid going off topic

[@CHRISTAMOSPAGHETTIO]

@@itanitv I'm not entirely sure what you just said but I am making my first game and it feels like you are saying I should change something to do with my main camera? Could you possibly dumb it down for me, I only started using Unity last night XD

[@benckis]

PrintName doent exist in curent context

[@Jacktherippler1]

you have to create a method with this name or just use print("xyz");

[@D-K-C]

[@DoomCatcher]

I would personally prefer you to do tutorials focused on the topic at hand and going into more detail rather than adding flashy stuff such as making the ball bounce.
