I had some thoughts that I'd like to +get some feedback on, and some code that you might find useful. + +I've put together a patch that changes the mouse control in snowballs so +that the mouse is normally free, and you have to click on the window +and move the mouse in order to move the view around. This is a change +from the current behavior where the mouse is always locked by the +application. This allows one to use other applications while the game +is running. I've even used it to have two instances of snowball running at +the same time, which should be useful for testing reasons. It'll also alow +for using the mouse in the future for clicking on controls on other parts of +the screen. The only thing I'm not sure about is how well it will work on +windows. It looks like it'll work, but it would be nice if someone +would test it. + +I used the right mouse button because the left mouse button is already +in use +for throwing a snowball, but I think these changes to the controls would +work better: + +* Left mouse button to move the view around +* Right mouse button to move forward +* Space button to throw a snowball +* Enter button to enter chat mode + After text is typed and enter is pressed, return from chat mode +* Mousewheel forward to zoom in +* Mousewheel backwards to zoom out +* Left button turns the view left normally +* If control+left or left_mouse+left, then strafe left +* Right button turns the view right normally +* If control+right or left_mouse+right, then strafe right + +The normal mode/chat mode allows us to use the keys for functionality rather +than F1-F12, which is a little harder to remember than something like +'r' for +toggle radar. Also, there are a limited number of function buttons, so I +think having access to all the other keys would allow good future expansion. + +The changes to the mouse buttons allows one to move around the world using +only the mouse. + +It would also be nice to have the ability to customize these keys, but +that's +something for a little later. + +If anyone has any comments about this stuff, I'd love to hear them. + +Patch to use right mouse button to move the heading around: + +Index: move_listener.cpp +=================================================================== +RCS file: /home/cvsroot/code/client/src/move_listener.cpp,v +retrieving revision 1.23 +diff -c -r1.23 move_listener.cpp +*** move_listener.cpp 2001/04/10 10:20:48 1.23 +--- move_listener.cpp 2001/04/13 02:21:30 +*************** +*** 54,63 **** + \****************************************************************/ + CMoveListener::CMoveListener() + { +! _MouseFree = false; + +- _CursorInit = false; +- + _Width = 0; + _Height = 0; + +--- 54,61 ---- + \****************************************************************/ + CMoveListener::CMoveListener() + { +! _MouseFree = true; + + _Width = 0; + _Height = 0; + +*************** +*** 184,190 **** + \****************************************************************/ + void CMoveListener::operator()(const CEvent& event) + { +! static const float eps = 0.001f; + + // Rotation + if (event==EventMouseMoveId) +--- 182,188 ---- + \****************************************************************/ + void CMoveListener::operator()(const CEvent& event) + { +! static const float eps = 0.002f; + + // Rotation + if (event==EventMouseMoveId) +*************** +*** 196,240 **** + + if(!_MouseFree) + { +! if(_CursorInit) + { +! float difx = 0.5f-mouseEvent->X; +! float dify = -(0.5f-mouseEvent->Y); +! if( (float)fabs(difx) > eps || (float)fabs(dify) > eps) + { +! if ( (float)fabs(difx) > eps) +! { +!
