    {
        auto window = static_cast<GLFWwindow*>(Application::Get().GetWindow().GetNativeWindow());
        double xPos, yPos;
        glfwGetCursorPos(window, &xPos, &yPos);
        return { (float)xPos, (float)yPos };
 
    }

IsMouseButtonPressed()

bool Vesper::Input::IsMouseButtonPressed ( int button )

static

Checks if the specified mouse button is currently pressed.

Parameters

button

The mouse button to check.

Returns
