How to check if mouse over object without adding so many scripts?
I need to check if my mouse is over an object. The problem is that there are a ton of those same objects. Like A LOT of those objects. Do I have to add a script to every object that contains void OnMouseDown() or can I do something inside my main player script? I really need help with this and I cannot find an answer online because it hasnt been asked probably. If I do have to add a script to all those objects, will it slow down my game at all? Thanks and all tips are appreciated.
(If you want more information on what I am doing, I am trying to make a cover system in my game. Whenever my mouse is over an object, my player will move to cover in that specific cover area.) Thanks guys!!
Use RayCast instead, it will require only one script.
For example:
var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
var hit : RaycastHit;
if (Physics.Raycast (ray, hit, 1000)) {
Debug.Log("You hit: "+hit.collider.gameObject);
}
Is this going to check whether my mouse is over an object or not? How can I check it using tags? The tag is called "cover" thanks for the quick response
Yes, after "if", you can write, for example: if(hit.collider.gameObject.tag=="cover") { Debug.Log("your mouse is hovering: "+hit.collider.gameObject); }
Wow, I never knew you can use a ray for the mouse position. This helps soooo much! Now I can not only make a cover system, but an interaction system! This is really well done thanks.
No problem. Don't forget to use this in Update function.
Quick question sorry hahaah. I convereted this to C# and I get these errors
UnityException: You are not allowed to call this function when declaring a variable. $$anonymous$$ove it to the line after without a variable declaration. If you are using C# don't use this function in the constructor or field initializers, Ins$$anonymous$$d move initialization to the Awake or Start function. $$anonymous$$ainPlayerScript..ctor ()
Assets/C# Scripts/$$anonymous$$ainPlayerScript.cs(25,35): error CS0165: Use of unassigned local variable hit' Assets/C# Scripts/$$anonymous$$ainPlayerScript.cs(25,21): error CS1502: The best overloaded method match for UnityEngine.Physics.Raycast(UnityEngine.Ray, out UnityEngine.RaycastHit, float)' has some invalid arguments
Assets/C# Scripts/$$anonymous$$ainPlayerScript.cs(25,21): error CS1620: Argument #2' is missing out' modifier
And here is the code I converted it to:
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast (ray, hit, 1000f)) {
}
change if statement: if (Physics.Raycast (ray, out hit, 1000f))
