Description

The current mouse position in pixel coordinates. (Read Only).

Input.mousePosition is a Vector3 for compatibility with functions that have Vector3 arguments. The z component of the Vector3 is always 0.

The bottom-left of the screen or window is at (0, 0). The top-right of the screen or window is at (Screen.width, Screen.height).

Note: Input.mousePosition reports the position of the mouse even when it is not inside the Game View, such as when Cursor.lockState is set to CursorLockMode.None. When running in windowed mode with an unconfined cursor, position values smaller than 0 or greater than the screen dimensions (Screen.width,Screen.height) indicate that the mouse cursor is outside of the game window.

In the following example, the x and y coordinates of the mouse position are printed when the “Fire1” button is clicked.

Getting mouse position in unity

So how can I get the current mouse position?

Trending sort

Trending sort is based off of the default sorting method — by highest score — but it boosts votes that have happened recently, helping to surface more up-to-date answers.

It falls back to sorting by highest score if no posts are trending.

Input.mousePosition will give you the position of the mouse on screen (pixels). You need to convert those pixels to the world units using Camera.ScreenToWorldPoint().

You can follow this link to learn how to drag a 3d object with the mouse or you can copy this code to move an object from the current position to the mouse position.

The conversion with ScreenToWorldPoint is straight-forward for 2D Vectors:

That is the current mouse position. The issue is that your objects are in world coordinates and the mouse is using screen coordinates.

You need to convert the mouse position using Camera.ScreenToWorldPoint().

If you wanted to use the new Unity InputSystem you could do the following:

Note that you need to install the InputSystem package for this to work.

ScreenToWorldPoint returns a point in world space, at the provided z distance from the camera.
