Problem with mouse events

[AndrewT]

I'm trying to figure out how I can get mouse presses; that is, I want a function to return true only when the mouse is initially pressed, after that it will return false until the next time I click the mouse. Here's my event receiver code:

Code: Select all

class MyEventReceiver : public IEventReceiver
{
public:

	MyEventReceiver( )
	{
		MouseLeftClicked = 0;
		MouseLeftHeld = 0;
		return;
	}
	bool OnEvent( const SEvent &event )
	{
		if ( event.EventType == EET_MOUSE_INPUT_EVENT )
		{
			if ( event.MouseInput.Event == EMIE_LMOUSE_PRESSED_DOWN )
			{
				if ( MouseLeftHeld == 0 )
				{
					MouseLeftClicked = 1;
				}
				else
				{
					MouseLeftClicked = 0;
				}
				MouseLeftHeld = 1;
			}
			if ( event.MouseInput.Event == EMIE_LMOUSE_LEFT_UP )
			{
				MouseLeftClicked = 0;
				MouseLeftHeld = 0;
                        }
		}
		return false;
	}
	bool GetMouseLeftClicked( )
	{
		return MouseLeftClicked;
	}
	bool GetMouseLeftHeld( )
	{
		return MouseLeftHeld;
        }
private:

	bool MouseLeftClicked;
	bool MouseLeftHeld;

};

And it's not working. GetMouseLeftClicked( ) is returning true as long as the left button is being held, but it should only be returning true one time when the mouse is pressed. Any ideas what's going wrong? I know I'm probably missing something really stupid and obvious.

event

Code: Select all

event.MouseInput.Event == EMIE_LMOUSE_PRESSED_DOWN 

is generated only one time when you click left button
MouseLeftHeld becomes 1 and MouseLeftClicked becomes also 1. The execution of event stops, so this code will never be checked:

Code: Select all

            else 
            { 
               MouseLeftClicked = 0; 
            }

Ahhhh, ok. Thanks.

Is EMIE_LMOUSE_LEFT_UP the same way? Will it only be generated once when the mouse button is released, or is generated constantly as long as the mouse button is up?

The mouse button events only come when the state of the mouse buttons have changed. This is consistent for all mouse button events.

K, thanks.
