Rotatesprite

rotatesprite <x> <y> <zoom> <ang> <tilenum> <shade> <pal> <orientation> <x1> <y1> <x2> <y2>
rotatespritea <x> <y> <zoom> <ang> <tilenum> <shade> <pal> <orientation> <alpha> <x1> <y1> <x2> <y2>

rotatesprite displays tiles onscreen.

Note: This command is similar to the deprecated myospal and myospalx commands, but with much more control.

Parameters

<x>	X coordinate, normally ranged 0-320
<y>	Y coordinate, normally ranged 0-200
<zoom>	is normally 65536. (ex: 131072 is zoomed in 2X and 32768 is half-sized)
<ang>	is the angle, normally 0, where 360 degrees corresponds to 2048 Build units
<tilenum>	is the tile number.
<shade>	is 0 normally but can be any standard shade up to 31 or 63.
<pal>	can be from 0-255.
<orientation>	a bitfield describing translucency, masking, etc...
<alpha>	translucence, 0-255. Note: Select a blend table instead of alpha by using a negative value.
<x1> <y1> <x2> <y2>	are boundaries on the screen that define where the tile may be drawn. If you want to draw a menu, use orientation bit 8, and the boundaries 0 0 xdim-1 ydim-1 as shown in example #2. If you want to draw a weapon, do not use bit 8 and use boundaries windowx1 windowy1 windowx2 windowy2, as shown in example #1. The difference is that xdim and ydim stay constant, while the other four shrink depending on the player's screen size.

Orientation

The following values are used by rotatesprite, rotatesprite16, rotatespritea, screentext, gametext, minitext, digitalnumber, digitalnumberz, myos and myospalx.

Exposed	Value	Label	Description
No	1	RS_TRANS1	Translucency level one (66% opacity).
No	2	RS_AUTO	Scaling on 320-200 coordinates. This is implicitly applied to all CON screen drawing commands, but including it in your bitfields is recommended for clarity and portability of your code.
No	4	RS_YFLIP	Used to invert Y coordinates. Combine this bit with an angle of 1024 (using rotatesprite) and the tile will appear to have inverted X coordinates. If you want inversion for both the X and Y coordinates, simply set the angle (again, with rotatesprite) to 1024 and do not use this bit.
No	8	RS_NOCLIP	Causes the sprite to be not affected by the screen size (using the + or - commands). This is usefull, for example, when displaying a status bar.
No	16	RS_TOPLEFT	Forces the center of the sprite you're drawing to its top-left if set. It also ignores the x-y offset of the tile.
No	32	RS_TRANS2	Translucency level two (33% opacity). It won't work if 1 is not set.
No	64	RS_NOMASK	Forces masking off if set. It discards translucency too.
No	128	RS_PERM	"Permanent" tile (deprecated).
No	256	RS_ALIGN_L	Align to the left (widescreen support)
No	512	RS_ALIGN_R	Align to the right (widescreen support)
No	1024	RS_STRETCH	Stretch to screen resolution (distorts aspect ratio; this is the behavior of rotatesprite prior to widescreen awareness)
No	2048	ROTATESPRITE_FULL16	Always interpret coordinate values as having "full" precision, bit-shifted left by 16, so that 20971520x13107200 corresponds to 320x200. See rotatesprite16.
No	4096	RS_LERP	Enables interpolation of coordinates between rotatesprite calls per guniqhudid. Changes of tilenum reset interpolation.
No	8192	RS_FORCELERP	Forces interpolation, even if the tilenum changes between calls.

As with cstat, the bit values can be added together and used in combination. For example, orientation 33 (32+1) is transparency level two, and orientation 5 (4+1) is transparency level one with inverted Y coordinates.
