Duplicated mouse events?

[Clash]

Hello!
Just updated my code to irrLicht 1.4beta, but now I'm getting this weird problem where I get duplicated mouse events (not sure about the others events, I think they are normal)

I thought it was my code, but I just tested with the example 4

Code: Select all

class MyEventReceiver : public IEventReceiver
{
public:
	virtual bool OnEvent(const SEvent& event)
	{
		/*
		If the key 'W' or 'S' was left up, we get the position of the scene node,
		and modify the Y coordinate a little bit. So if you press 'W', the node
		moves up, and if you press 'S' it moves down.
		*/

		if (node != 0 && event.EventType == irr::EET_KEY_INPUT_EVENT&&
			!event.KeyInput.PressedDown)
		{
			switch(event.KeyInput.Key)
			{
			case KEY_KEY_W:
			case KEY_KEY_S:
				{
					core::vector3df v = node->getPosition();
					v.Y += event.KeyInput.Key == KEY_KEY_W ? 2.0f : -2.0f;
					node->setPosition(v);
				}
				return true;
			}
		}

		if (event.EventType == irr::EET_MOUSE_INPUT_EVENT)
        {
            switch(event.MouseInput.Event)
            {
                case EMIE_LMOUSE_PRESSED_DOWN:
                {
                    std::cout << "pressed";
                }
            }
        }

		return false;
	}
};

As soon as I press the left mouse button, it prints pressed twice, "pressedpressed"

Any idea guys? The rest of the code is exactly as example 4

Thanks[/code]

I think you should return true in "case EMIE_LMOUSE_PRESSED_DOWN".

This was a bug that is now fixed in SVN, the final 1.4 release won't have this problem

The problem was, the user receiver gets mouse input before the GUI, so if it isn't absorbed by the user then it is passed to the GUI. If the GUI doesn't catch the mouse event then it is passed back to the user receiver - causing two mouse events.

You can view the change to CGUIEnvironment.cpp here
