Capturing Mouse Position w/o Polling Every Update?

Question

Hey everyone,

For my GUI, I'd like to use keep track of the mouse position while avoiding simply polling for the position every Update(). Ideally, I'd like to leverage the "mouseMove" event since then I can unnecessary code execution when the mouse position hasn't changed, but the mouseMove Event isn't fired in game (only the editor, see http://unity3d.com/support/documentation/ScriptReference/EventType.MouseMove.html).

Does anyone have a good workaround for this problem? Is there a efficient, standard way to capture mouse position that I'm just overlooking?

Thanks,

Nate

Since your problem is a high-cost operation which you need to do each move, solve this by comparing the mousePosition to what it was in the previous frame and avoid the operation when the change is zero. The actual cost of reading mousePosition is immaterial.

This is an old question, and I agree with the answer: but there is another work around that may work for some: events are fired during MouseDrag you can catch. Read the docs on it if appropriate for you.

Update: There is now a new Input System package which could do this more generically without code.
