<h3>Remarks:</h3>
<ul>
<li> When using <b>sys_record()</b> and <b>sys_replay()</b> during gameplay
for recording a demo, execute a <b>game_save()</b> / <b>game_load()</b> instruction
before for starting the demo from the same position within the level.</li>
<li><span class="tast">[Ctrl-Alt-Esc]</span> stops recording and replaying
(development version only). Setting <a href="record_mode">record_mode</a> to 0 also stops recording
and replaying.</li>
<li> The command line options <b>-rec</b> and <b>-rpl</b> automatically record
or replay all keyboard and mouse input from the beginning to the file <b>tape.rec</b> (development
version only). Joystick movements and buttons are not recorded. This can
be used to reproduce a certain movement sequence for debugging purposes.</li>
<li>During replay, the application will still react on hitting keyboard or
mouse buttons, but not on mouse or joystick movements.</li>
<li>The <a href="atime.htm">time_step</a> and <a href="atime.htm">time_frame</a> variables
are recorded and replayed also for precisely reproducing movements. </li>
</ul>
<h3>Example:</h3>
<pre><em>// Record a demo from the current position</em><i>
</i>game_save("record",0,SV_ALL-SV_INFO);
wait(1);
sys_record("record.rec",1);
...
game_load("record",0);
wait(1);
sys_replay("record.rec");</pre>
