拖动后的Java鼠标

Question

I'm making a small game project in Java. In it you have a character that shoots in the direction of the mouse when "pressed" or "dragged" (you know, in Java's terms). The only problem is that if you stop dragging but you still hold the left mouse button down you stop shooting.

Is there a way to detect if the mouse button is down after a drag?

NOTE: the mouse is not sensed as "pressed" after the drag.

Answer 1

You will get the information when a mouse button is pressed and when it is released again. If you want to know the state in between, you need to use a boolean to store that information.

Example:

final boolean[] buttonStates = new boolean[3];

public void mousePressed(MouseEvent e) {
  buttonStates[e.getButton()] = true;
}

public void mouseReleased(MouseEvent e) {
  buttonStates[e.getButton()] = false;
}

You would do the same for keyboard input by the way.
