mouse.Position

How would I get the position of where the mouse is? Like, in Vector3, not Vector2

In an old engine called ROBLOX, I would convert it like this:


new Vector3 mouse_pos = new Vector(mouse.Hit.p);

 

This one,
http://docs.unity3d.com/ScriptReference/Input-mousePosition.html

 

Not working the way I want.
First of all, I want the center to be 0.
Second, it's 2d, not 3d, third of all, i think its to sensitive

 

An example of what (I think) you want. Finding the position the mouse is hovering over.

Code (csharp):

1.  
2. Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
3. RaycastHit hit;
4. if (Physics.Raycast(ray, out hit, 100)) {
5.     // hit.point is the value you're looking for
6. }
7.  

Keep in mind there needs to be a collider for it to hit.

 

To get world space (3D),
http://docs.unity3d.com/ScriptReference/Camera.ScreenToWorldPoint.html

or in viewport coords:
http://docs.unity3d.com/ScriptReference/Camera.ScreenToViewportPoint.html

 

So uh, how would I put the transform at hit.point or whatever?

 

Code (csharp):

1.  
2. transform.position = hit.point;
3.  

That's my best guess, I don't know what you're trying to do.

 

Yeah, I tryed that, but um.... it's weird. It like.... keeps on teleporting to the main camera and going back in an endless loop when im not moving my mouse at all.

 

Post your code and what you are trying to accomplish.

 

I am trying to accomplish a cube following the mouse with Vector3.

using UnityEngine;
using System.Collections;

public class asdfasdf : MonoBehaviour {

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit, 100)) {
// hit.point is the value you're looking for
transform.position = hit.point;
}
}
}


Problem: It does not stay at the mouse unless I take my mouse off the object. If i keep it on the object with my mouse on it, the cube moves towards the main camera, and once reached teleports back to my mouse's position and starts over again.

 

When posting code, please use code tags.

 

I'm guessing that the object you are trying to move also has a collider on it, so after the first frame the Raycast is now hitting that object. You will want to keep your Raycast from hitting that object by either using a LayerMask or assigning it to the 'ignore raycast' layer.

 

ty its fixed ur the best

 

Nope, it's still needs the tag.

 

What...?
Its fixed.

 

Nope, it is not fixed yet. Which post are you talking about?

 

Ok, then, if you want, you can help me fix it.
I'm making a game where you have a like shop and can build things.
It works great, so far, but ignore raycast makes it so it does not detect the brick I put down, therefore I cannot stack the bricks. How can I fix this?

 

You can disable the collider of the brick you are placing, then enable it after it has been placed.

EDIT: This is instead of placing it in the ignore raycast layer.

 

Daniel, unfortunately, it does not work when i activate and disable the collider. It still glitches out and teleports to the camera. Anyways, it is starting to get in the way. for some reason, my colliders are not working when I have ignore raycast on.?

 

When a collider is disabled, it is no longer detected by Raycasts.

Post your code.

 

How does code have to do with this?
Which code? my collider code or my raycast code? Heres uh.. some of it.

Unfortunately, with the new unity forum setup, I cannot find the code tags.

So uh please cope.


Following Mouse:

juj is a boolean that is true at the start


if(juj == true){
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit, 100)) {
// hit.point is the value you're looking for
transform.position = hit.point + new Vector3(0,Scale_Y_Divided_By_2,0);
asd = transform.position;
}
}


Putting Down:

if(Input.GetMouseButtonDown(0)){
if(Paid == false){
Money.Cash -= Cost;
Paid = true;
}
transform.position = asd;
juj = false;
}

 

Who needs the button ? Just mark it up manually, all you have to do is write: [code_]void DoSomething();[/code] without the underscore of course. It's easy!

 

Everything.

Unfortunately I'm having a hard time understanding your code though. It looks like you are only allowing a single placement, is that correct?

Either way, make sure that the collider on your GameObject is disabled, or disable it on Awake so that the Raycasts won't interact with it.

 

A single placement at a time.
Sorry for not explaining this before, but I have a shop that copies a prefab with this script in it.

 

Oh well. Why don't I try that LayerMask thing? How do I do that?

 

LayerMask

The LayerMask route is very similar to the collider route, except instead of enabling/disabling the collider you are changing the layer of the object.
