View source for Template:Orientation

orientation is a parameter used in several of the screen drawing commands, including [[digitalnumber]] and [[rotatesprite]]

orientation is a bitfield, the flags of which determine how a sprite is drawn.  Here are the known bits and what they do.  There may be others:


Bit 1 (1) is translucency level one (66% opacity).

Bit 2 (2) is scaling on 320x200 coordinates. It's considered internal in the case of CON commands because the CON interface automatically sets it when you use functions calling rotatesprite (rotatesprite as well as various text functions).

Bit 3 (4) is used to invert Y coordinates.

Bit 4 (8) combine with a angle of 1024 and will flip the tile horizontal.

Bit 5 (16) forces the center of the sprite you're drawing to its top-left if set. If not, its center as set in editart will be drawn at the specified coordinates.

Bit 6 (32) is translucency level two (33% opacity). It won't work unless bit 1 is also set.

Bit 7 (64) forces masking off if set. It discards translucency too.


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.
