Pre-defined values

Globalflags

Used with globalflags userdef or globalflags DEF command.

Value	Label	Description
1	GLOBAL_NO_GL_TILESHADES	Disable tile shades (aka palette emulation) in OpenGL
2	GLOBAL_NO_GL_FULLBRIGHT	Disable fullbright colors in OpenGL
4	GLOBAL_NO_GL_FOGSHADE	Make visibility the same for all shades in OpenGL. With this, positive shades won't appear darker with visibility, and negative shades won't appear brighter (and negative shades will have virtually no difference from shade zero). As a result, positive shades won't look even darker with distance, while negative shades will look the

Globalgameflags

Used with globalgameflags userdef or globalgameflags DEF command.

Value	Label	Description
1	DUKE3D_NO_WIDESCREEN_PINNING	Disable widescreen orientation bits for weapon sprites drawn on screen. Enable this if you are using weapon sprites extended on the sides (similar to 20th Anniversary World Tour).
2	DUKE3D_NO_HARDCODED_FOGPALS	Disable the four fog palettes. By default Eduke32 will create four new palettes, with IDs ranging from 26 to 29 (however it varies depending of the size of the lookup table).
4	DUKE3D_NO_PALETTE_CHANGES	Disable changes to the game palette. By default Eduke32 will attempt to replace the magenta color used for transparency with the color closest to black.

Orientation

Used with rotatesprite, screentext and other screen drawing commands.

Value	Label	Description
1	RS_TRANS1	Translucency level one (66% opacity).
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.
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.
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.
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.
32	RS_TRANS2	1| is not set.
64	RS_NOMASK	Forces masking off if set. It discards translucency too.
128	RS_PERM	"Permanent" tile (deprecated).
256	RS_ALIGN_L	Align to the left (widescreen support)
512	RS_ALIGN_R	Align to the right (widescreen support)
1024	RS_STRETCH	Stretch to screen resolution (distorts aspect ratio; this is the behavior of rotatesprite prior to widescreen awareness)
2048		Always interpret coordinate values as having "full" precision, bit-shifted left by 16, so that 20971520x13107200 corresponds to 320x200. See rotatesprite16.

Text Properties

Used with screentext.

Value	Label	Description
1	TEXT_XRIGHT	Right-align text on the x-axis. For example, you could display text at x=320 with this flag and the string's right edge would be on the right edge of the screen.
2	TEXT_XCENTER	Center-align text on the x-axis. For example, you could display text at x=160 with this flag and the string would be perfectly horizontally centered.
4	TEXT_YBOTTOM	Bottom-align text on the y-axis. For example, you could display text at y=200 with this flag and the string's bottom edge would be on the bottom edge of the screen.
8	TEXT_YCENTER	Center-align text on the y-axis. For example, you could display text at y=100 with this flag and the string would be perfectly vertically centered.
16	TEXT_INTERNALSPACE	If you are unsure what to specify for the <xspace> parameter, this flag will allow EDuke32 to make its own determination. Don't use this unless you have no idea whatsoever. The <xspace> value will be added to the internal result.
32	TEXT_TILESPACE	The <xspace> parameter will be determined using the width of the tile after '~'. Good for custom fonts. (NB: <xbetween> is added to spaces just like any other character.) The <xspace> value will be added to the result.
64	TEXT_INTERNALLINE	If you are unsure what to specify for the <yline> parameter, this flag will allow EDuke32 to make its own determination. Don't use this unless you have no idea whatsoever. The <yline> value will be added to the internal result.
128	TEXT_TILELINE	The <yline> parameter will be determined using the height of the tile after '~'. Good for custom fonts. The <yline> value will be added to the result.
256	TEXT_XOFFSETZERO	Calculate spacing between characters from the left edge instead of the right. In other words, <xbetween> is used as a constant width for the characters in the string and the potentially variable widths of the tiles displayed in the string are ignored.
512	TEXT_XJUSTIFY	Justify text in the X direction, using <xbetween> for the total width (since the actual distance will be calculated automatically). Compatible with TEXT_XRIGHT and TEXT_XCENTER.
1024	TEXT_YOFFSETZERO	Calculate spacing between line from the top edge instead of the bottom. In other words, <ybetween> is used as a constant height for the lines in the string and the potentially variable heights of the tiles displayed in the string are ignored.
2048	TEXT_YJUSTIFY	Justify text in the Y direction, using <ybetween> for the total height (since the actual distance will be calculated automatically). Compatible with TEXT_YBOTTOM and TEXT_YCENTER.
4096	TEXT_LINEWRAP	Enable a hackish internal line wrapping feature used by some text in the executable (such as multiplayer messages) that will wrap a string back to its starting X position at the point when a character would go off the screen. This flag has no effect if any alignment flags are used or if the <block angle> is not a multiple of 512, which includes 0--perfectly horizontal or vertical.
8192	TEXT_UPPERCASE	Force the case of all letters in the string to uppercase.
16384	TEXT_INVERTCASE	Invert the case of the letters in the string. Combine with TEXT_UPPERCASE to produce all-lowercase output.
32768	TEXT_IGNOREESCAPE	Palette escape sequences (^# or ^##) will have no effect. (See definequote.)
65536	TEXT_LITERALESCAPE	No parsing will be done for palette escape sequences so they will show up as actual text. This is useful if you have '^' followed by a number that you actually want to display on the screen, such as exponentiation.
131072	TEXT_BACKWARDS	Iterate through the string backwards. (TEXT_LITERALESCAPE is highly recommended because there is not a separate pass to escape the palette sequences forwards.)
262144	TEXT_GAMETEXTNUMHACK	All numerals will display as if they have a TEXT_XOFFSETZERO of the width of the '0' minus one. For the standard blue font, this value would be 8. This is useful if you have some string including a number value (such as a countdown timer) that you want to display without the place values shifting due to variable width tiles, particularly '1'.
524288	TEXT_DIGITALNUMBER	Special tile order: starting at '0' instead of 'A'. Using this flag with quotes containing anything other than numbers may give you undefined behavior. (Recommended tile numbers: DIGITALNUM (#2472), THREEBYFIVE (#3010))
1048576	TEXT_BIGALPHANUM	Special tile order: main menu red font. As in v1.3D, the gray font serves as the lowercase letters, so TEXT_UPPERCASE is recommended. (Recommended tile number: BIGALPHANUM (#2930))
2097152	TEXT_GRAYFONT	Special tile order: gray font. To parallel the above flag, the red font serves as the lowercase letters, so TEXT_UPPERCASE is recommended. The primary difference compared to using the above flag with the lowercase flags is that the gray font has its own set of numerals. The red font's punctuation is still used. (Recommended tile number: #2966)
