r_things.c
|
The number of sprite names currently recognised by SRB2, except those for character skins. This is only set on game startup by R_InitSprites, where it is used to count the total number the number of sprite names found in sprnames – because sprnames has a size of NUMSPRITES and has a sprite name set in every slot, numsprites will always have a value of NUMSPRITES in unmodified SRB2.
|
*sprites
|
spritedef_t
|
r_things.c
|
The lookup table for all sprite definitions in SRB2, except those for character skins. Has a size of numsprites. Individual sprite definitions may be updated whenever a WAD file that declares new sprite names or has replacements for existing sprites is loaded.
|
numvertexes
|
size_t
|
p_setup.c
|
The number of vertices in the current map.
|
*vertexes
|
vertex_t
|
p_setup.c
|
The lookup table for the current map's vertices. Has a size of numvertexes.
|
numsegs
|
size_t
|
p_setup.c
|
The number of segs in the current map.
|
*segs
|
seg_t
|
p_setup.c
|
The lookup table for the current map's segs. Has a size of numsegs.
|
numsectors
|
size_t
|
p_setup.c
|
The number of sectors in the current map.
|
*sectors
|
sector_t
|
p_setup.c
|
The lookup table for the current map's sectors. Has a size of numsectors.
|
numsubsectors
|
size_t
|
p_setup.c
|
The number of subsector in the current map.
|
*subsectors
|
subsector_t
|
p_setup.c
|
The lookup table for the current map's subsectors. Has a size of numsubsectors.
|
numnodes
|
size_t
|
p_setup.c
|
The number of nodes in the current map.
|
*nodes
|
node_t
|
p_setup.c
|
The lookup table for the current map's nodes. Has a size of numnodes.
|
numlines
|
size_t
|
p_setup.c
|
The number of linedefs in the current map.
|
*lines
|
line_t
|
p_setup.c
|
The lookup table for the current map's linedefs. Has a size of numlines.
|
numsides
|
size_t
|
p_setup.c
|
The number of sidedefs in the current map.
|
*sides
|
side_t
|
p_setup.c
|
The lookup table for the current map's sidedefs. Has a size of numsides.
|
| POV data
|
viewx
viewy
viewz
|
fixed_t
|
r_main.c
|
The X, Y and Z coordinates of the point of view (POV) to render the level from for the current frame.
|
viewangle
aimingangle
|
angle_t
|
r_main.c
|
viewangle is the absolute horizontal angle the POV is looking in for the current frame.
aimingangle is the vertical viewing angle (or pitch/aiming angle) the POV is looking in for the current frame. An angle of 0 is looking directly forward, ANGLE_90 would be looking directly upwards, ANGLE_180 would be looking directly backwards, and ANGLE_270 would be looking directly downwards. In practice however neither the Software nor OpenGL renderers allow aimingangle to go beyond ANGLE_90 upwards or downwards.

viewangletox[FINEANGLES/2]
|
INT32
|
r_main.c
|
The lookup table for converting view angles to screen X coordinates. The given view angle must be shifted down to fine angle scale with ANGLETOFINESHIFT first in order to get the corresponding X coordinate. This table will be updated whenever the screen resolution is changed.
|
xtoviewangle[MAXVIDWIDTH+1]
|
angle_t
|
r_main.c
|
The lookup table for converting screen X coordinates to view angles. Specifically, this gives the smallest view angle that maps to each X coordinate. This table will be updated whenever the screen resolution is changed.
|
rw_distance
|
fixed_t
|
r_segs.c
|
A calculated "distance" value from the POV to the current seg being drawn, used by R_ScaleFromGlobalAngle to determine the texture mapping scales to draw the seg at on the screen (the larger the rw_distance value is the smaller the scales given will be). Specifically, this is calculated to be the closest distance the POV would be from the seg if both ends of the seg's line were extended infinitely.
|
rw_normalangle
|
angle_t
|
r_segs.c
|
The absolute angle of the normal of the current seg being drawn (i.e.: the angle perpendicular to the seg's angle, directed towards the POV).
|
rw_angle1
|
angle_t
|
r_segs.c
|
The absolute angle of the POV to the left vertex (v1) of the current seg being drawn.
