Questions
[6] I'm using a slow terminal, and the game response is sluggish.
What can I do?
[7] Why can't my terminal hide the cursor?
+[8] Occasionally when clearing a line, the display jerks, scrolling
+ very awkwardly. How can I fix it?
Answers
=======
before running Netris. If that doesn't work, your terminal
probably doesn't support cursor invisibility.
+[8] Occasionally when clearing a line, the display jerks, scrolling
+ very awkwardly. How can I fix it?
+
+ You can try running ./Configure with the "--curses-hack" option
+ and recompile. This utilizes a non-portable hack which will only
+ work with certain curses libraries, so it's disabled by default.
+
+ All screen updating is done by your curses library, which means
+ it's not something that Netris can control. Netris never tells
+ curses to scroll, but curses does so automatically in order to
+ optimize screen updates. This hack modifies curses's internal
+ variables, making it think that your terminal doesn't know how to
+ region-scroll.

This is an unfinished developmental version of Netris, a free
networked version of T*tris. It is distributed under the terms
of the GNU General Public License, which is described in the
-file "COPYING" included with this distribution.
+file "COPYING" included with this distribution. For more
+information about GNU and the Free Software Foundation,
+check out <http://www.gnu.org/>.
In order to compile Netris you will need gcc. You may be able to
compile it with another ANSI C compiler, but if you attempt this
It's been built and tested on at least the following systems:
+ GNU/Linux
+ FreeBSD 2.1.5, 2.1.6, 2.2
NetBSD 1.0, 1.1
- Linux
SunOS 4.1.1, 4.1.3
Solaris 2.3, 2.4
HP-UX
See the FAQ in this directory if you have any problems.
-NEW IN VERSION 0.4
+NEW IN VERSION 0.5
==================
-- Netris now attempts to make the cursor invisible for terminals that
- support it. Xterm no, vt220 yes, vt100 maybe?
-- Ctrl-L (by default) will now redraw the screen.
-- Various cleanup and documentation changes.
+Netris now specifically looks for ncurses and uses color if it's
+available, unless the -C option is given. Thanks to A.P.J. van Loo
+<cobra@multiweb.nl> for providing code which these changes are
+based on.
INSTALLATION
'm' down faster
's' toggle spying on the other player
'p' pause
