XA number of people have asked some questions about Lunar Lander,
Xa number of other people (usually compiling on BSD) have sent some
Xpatches to deal with curses(3X) routines that are not in their version
Xof BSD curses. Here is a compilation of info these people offered/required.
X
XControlling the Lander
X----------------------
X
XThe lander is fitted with three rockets;
X
X /~\
X | |
X left -+++- right
X |
X vert. thrust
X
XPress keys '0' - '9' to set the default power level,
Xwhere '0' == no power and '9' == full power.
X
XPressing 'z' sets the power output of the left rocket
Xto the default, this has the effect of pushing the lander
Xto the right (if the default power level is > 0).
X
XPressing 'c' sets the power output of the right rocket
Xto the default, this has the effect of pushing the lander
Xto the left.
X
XPressing 'x' sets the vertical thrust of the middle rocket
Xto the default level, if this is non zero it will slow the
Xrate of descent of the lander. If it sets it to zero the
Xlander will drop like a brick!
X
XWhat's on the Screen
X--------------------
X
XThe top of the screen reads;
X
Xalt: X: dY: dX: Score:
X
X'alt' - is the current altitude from "sea level" in metres
X'X' - is how far you have moved horizontally (in meters)
X'dY' - is your rate of change of vertical movement, (e.g. -10.0
X means you fell 10 meters in the previous second)
X'dX' - is your rate of change of horizonal movement, (e.g. -10.0
X means you moved left 10 metres in the previous second)
X'Score' - is your current score.
X
XAt the bottom of the screen;
X
XThrust - L: vert: R: pow: Fuel:
X
X'L' - is thrust from the left rocket (pushes you to the right)
X'R' - is thrust from the right rocket (pushes you to the left)
X Both 'L' and 'R' alter the 'dX' value.
X'vert' - is thrust from the vertical rocket (slows the lander's
X rate of descent i.e. alters 'dY')
X'pow' - is the default power setting that will be used when you
X press 'z', 'x' or 'c'
X'Fuel' - the amount of fuel left, when this reaches zero all thrust
X from rockets ceases.
X
XThe two rules for landing are;
X 1. Try to get dY >= -5 metres per second, anything faster
X than -5 will cause the lander to explode.
X 2. Make sure you are landing on a pad.
X
XSome BSD Patches
X----------------
X
XGordon Vickers offered the following for Ultrix people (thanks)...
X
XTo deal with crmode() not being supported;
X
X File: screen.c
X Function: InitialiseScreen()
X Change: Added another #ifdef BSD
X initscr();
X noecho();
X | #ifdef BSD
X | crmode();
X | #else
X cbreak();
X | #endif
X *init_scr = stdscr
X
X Each of the above lines that start with a pipe ("|") represent lines
X that I've inserted. No lines were deleted.
X
XTo deal with endwin() leaving the cursor at to top of the screen;
X
X File: land.c
X Function: EndCurses()
X Change:
X while(wgetch(screen) != ' ');
X | clear();
X | refresh();
X endwin();
X
XHope this has been of some help.
