如何检查是否一直按住鼠标左键而不是只单击一次？

Question

bool WasMouseLeftClick()
{
    return (previousState.LeftButton == ButtonState.Pressed) && (currentState.LeftButton == ButtonState.Released);
}

This code return one single click on the mouse left button. But I want it to return when pressing the mouse left button without leaving the button and then moving the mouse around up,down,left,right.

How can I do it ?

Answer 1

Seems pretty straightforward to me.

bool WasMouseLeftDown()
{
    return currentState.LeftButton == ButtonState.Pressed;
}

This is simply a bool that returns true if the left mouse button is being held down in the current frame.

I think what you really want to do is when they move the mouse while the left mouse button is down so you simply need to check both conditions:

if (WasMouseMoved() && WasMouseLeftDown())
{
    // do something
}

I assume you already have code to check if the mouse moved (comparing the old position to the new position).
