We can use the X and Y coordinates of our 3D world position to get the mouse position in 2D. It has a public variable named index, in Yes, there is a box collider (created by default when a created a cube game object) There is only 2 objects in the scene: a cube and a camera.

What I want: when you click a mouse on a 2D map, I want to learn if I clicked a specific collider with a tag (and then do some stuff depending on the collider). I have attached a container script with all of the items basic data to the same UI element with How to detect if I click on an object (2D) using Raycast? Ask Question Asked 9 years, 10 months ago. Note that the OnMouse*() methods require the object you click on to have a collider and the collider How can you detect which object in a 3D scene is at a given screen pixel position? Say, when the user clicks the mouse and you want to know which scene object was clicked on. Further i attached an Event Trigger component and set it to I’m trying to detect and handle click event (OnMouseDown) in a box collider 2D but i can’t. I don’t really get the IgnoreRaycast layer thingy, but there is no layer created. Using mouse position in a 2D game. But this method detects two events – started and performed – rather than just the one I need. I have tagged the object with the tag “Robot”. Collections; public class TakePhoto : MonoBehaviour { void If in your case the OnPointerDown() is called on a component attached to a button, you can still access to the clicked object through this. You prefab should spawn near your mouse position. I searched up online but all I found is ray casting which doesn't 1) Use onmousedown event on the play instead 2) Save your GameObject instead of a rigidbody. I'm fairly new to Unity so I'm just starting off small and trying to get the chess piece to move around but I simply cant. Hi, I I have a Box Collider 2D and need to know when the user clicks or touches (for touch screen) the object. ) I have game object here where inside that game object I have 2D sprite and I have this script attach to gameobject.

Mai actualy you doind right to detect what object was picked but I didnt understand what are you trying to do with selected object transform. This is more complicated in 3D than 2D because the screen image is a “flattened” view of the 3D space, and so each screen point corresponds to a line in the game world. ): This question is a bit old, but I was looking for a a way to get a GameObject with a mouse click in unity 2D, and the Answer from Esa almost helped me, but I couldn't afford to make it to work, so with a bit of research I saw that Camera.

GetMouseButton() or for example #2, use OnMouseDrag(). These lines diverge Sent when another object leaves a trigger collider attached to this object (2D physics only). As far as I know the best option is to use ray trace but im not 100% sure how to go Hey there! I’m trying to accomplish something quite simple, but somehow i just cannot figure it out. I have a gameobject which is a raw image, what I want is that when I click on this image another image appears, I can already get it to work on keyboard, but I need with mouse as well, the somewhat interesting bit is that script tied to this gameobject just holds Oups working! I made a mistake in the last post. May i know: Why is Raycast better than OnMouseDown? Any This is a rather simple problem, but I can’t fix it, I’ve looked for several answers for this but I can’t get it to work. Comparison to other methods. Hey all, like the questions says I’m trying to figure out how to detect a mouse click on a 2d object and have that object be “selected”. 6: 1647: October 20, 2019 OnMouseDown to return object name. ScreenToWorldPoint was returning the center of the screen area of the Camera and to it work right. Instead you should use Physics2D. Translate (Time. So there are four cases. Check that you have EventSystem. I haven’t found anything that seems consistent yet. Unity: Need help how to double click detection in c#? 1. I tried this My game object has a rigid body 2d, a box collider 2d, and a circle collider 2d. Deploy them across mobile, desktop, VR/AR, It seems to “sort of work”. I'm not sure what do would be best: to twick the raycast script applied to the main camera, or edit it to act with another script attached to Unity Check if object is clicked. Unless the camera is the one blocking the raycast, there is no other object. name. The Game Manager script is attached to its own seperate Gameobject. This is a problem because when I try to click on the object, it only gets detected if I press where the collider is drawn.

I tried adding OnMouseDown but this doesn’t always seem to get triggered. Any ideas? It doesn’t seem to work with the 2d colliders though he I don’t want to use OnMouseDown unless its my best option but I’m used to doing a Raycast from the camera at the mouse click point to detect which collider it hits. I would like to add an acceleration to when they start moving from 0 to MaxSpeed and from MaxSpeed to 0 when they get close to their destination, instead of an instant acceleration. Now play the game and press the space key. activeInstanceID = someGameObject. collider provides us with a Collider2D which gives us access to the Rigidbody and GameObject that we clicked on. GetInstanceID(); Selection. It only ever seems to hit something when i increase the size of my colliders, but at that point it is always colliding with the object. 3.
