No current camera?

Unity Engine
1

A Canvis, add the script to the Canvas.

Update() call the below script.

void MouseClick()
    {
        if (Input.GetMouseButtonDown(0))
        {
            Ray ray = Camera.current.ScreenPointToRay(Input.mousePosition);
            print("aa");

            if (Physics.Raycast(ray, out hit))
            {}
}
}

The problem is that print is not executed, and the error is " reference to null " at the screenpointtoray.

If i change “current” to “main”, it works fine.

I only have one main camera in the scene, isnt current camera the same as main camera?

Use Camera.main.

Just like it tells you to.

Why ppl always think the document is enough and link them as answer? :frowning:

If document is so powerful, every student in colleagues should score 100 as long as they read textbook.

I have another project that have 3 camera, and the Camera.current work fine. That’s why i want to find out what happen.

Are you sure you’re using the Camera.current exactly the same way in the other project? Since Camera.current is the “camera we are currently rendering with, for low-level render control only”, I don’t think you should use it to handle input. Use Camera.main or assign your script a reference to the correct camera.

Actually the script is copied from the “ok” 3 cameras project, and then i find it doesnt work, so i change it to “main” in the new project.
