How to check if mouse is pressed (like an event)-CodePudding

I am a beginner to unity and I need to know how to detect when the mouse has went down

My script is parented to the camera (Because it is a camera script) and I need to know when the mouse button goes down so I can start to move the camera.

I also need to know when it moves, or goes up.

You should use the New Input System for this, it's got a little bit of a learning curve but has exactly what you are looking for as it is entierly based around input events.

There is a good explination here. You'll want to use the performed event of an input action, which is a regular event you can subscribe your functions to.

The performed event will corespond to whatever you set the action to be triggered by, for example the press down of a button if you set it so, or could be the press and release of a button.

So like:

cameraMoveAction.performed  =
    (_) =>
    {
        // move the camera
    };

You could specify, when exactly mouse button click should be detected. The most logical case is using UI. So here you are.
