CONAN:

showview <x> <y> <z> <angle> <horiz> <sector> <scrn_x1> <scrn_y1> <scrn_x2> <scrn_y2>

Displays on-screen the view from in-game coordinates (<x>,<y>,<z>), looking at angle <angle> and with z-angle <horiz>, between screen coordinates (<scrn_x1>,<scrn_y1>) and (<scrn_x2>,<scrn_y2>).

<sector> is the sector that contains the in-game coordinates.

The on-screen coordinates can be in any shape; they do not have to be in the same x-y ratio as the screen resolution. However, different ratios can result in warping or graphical glitches in the view. The on-screen coordinates are in 320x200 scale.

Keep in mind when using this command that the game will have to completely redraw everything from the specified perspective, which can produce a sizeable framerate hit.

This example will embed a small version of the player's view near the top left corner of the screen:

getplayer[THISACTOR].horizoff temp
addvarvar horiz temp
updatesectorz x y z sect
showview x y z ang horiz sect 16 8 56 39
</pre>

This lengthy example will create a "gun camera" that shows a closeup view of wherever the player is currently aiming. In addition to showview and basic EDuke commands, it also uses [[updatesectorz]], [[myos]], and [[hitscan]], as well as the [[event]] [[EVENT_DISPLAYREST]].
