M_Drawer Called after the view has been rendered, but before it has been blitted.

Checksum

Add an active ceiling

P_BlockLinesIterator The validcount flags are used to avoid checking lines that are marked in multiple mapblocks, so increment validcount before the f

P_BringUpWeapon Starts bringing the pending weapon up from the bottom of the screen. Uses player

P_CalcHeight Calculate the walking / running height adjustment

P_CheckMissileSpawn Moves the missile forward a bit and possibly explodes it right there.

P_CrossSubsector Returns true if strace crosses the given subsector successfully.

P_FireWeapon.

P_InitThinkers

P_InterceptVector Returns the fractional intercept point along the first divline. This is only called by the addthings and addlines traversers.

P_Move Move in the current direction, returns false if the move is blocked.

P_MovePsprites Called every tic by player thinking routine.

P_RadiusAttack Source is the creature that caused the explosion at spot.

Remove a ceiling's thinker

P_TeleportMove

P_Thrust Moves the given origin along a given angle.

P_UseSpecialLine Called when a thing uses a special line. Only the front sides of lines are usable.

R_CheckPlane

R_CheckTextureNumForName Check whether texture is available. Filter out NoTexture indicator.

R_DrawVisSprite mfloorclip and mceilingclip should also be set.

R_ExecuteSetViewSize

R_FindPlane

R_InstallSpriteLump Local function for R_InitSprites.

R_MapPlane Uses global vars: planeheight ds_source basexscale baseyscale viewx viewy BASIC PRIMITIVE

R_PointOnSide Traverse BSP (sub) tree, check point against partition plane. Returns side 0 (front) or 1 (back).

R_RenderMaskedSegRange

R_ScaleFromGlobalAngle Returns the texture mapping scale for the current line (horizontal span) at the given angle. rw_distance must be calculated fir

R_Subsector Determine floor/ceiling planes. Add sprites of things in sector. Draw one or more line segments.

Changes volume, stereo-separation, and pitch variables from the norm of a sound effect to be played. If the sound is not audible, returns a 0. Otherwi

Draws "Entering <LevelName>"

Display level completion time and par, or "sucks" message if overflow.

W_InitMultipleFiles Pass a null terminated list of files to use. All files are optional, but at least one file must be found. Files with a .wad extens

W_ReadLump Loads the lump into the given buffer, which must be >= W_LumpLength().

Z_ChangeTag

getSector() Will return a sector_t given the number of the current sector, the line number and the side (0/1) that you want.

twoSided() Given the sector number and the line number, it will tell you whether the line is two-sided or not.

should be called at the start of every level right now, i figure it out myself

Handle events (user inputs) in automap mode

Updates on Game Tick

adds a marker at the current location

Zooming

Clear automap frame buffer.

Automap clipping of lines. Based on Cohen-Sutherland clipping algorithm but with a slightly faster reject and precalculated slopes. If the speed is

Classic Bresenham w/ whatever optimizations needed for speed

Draws flat (floor/ceiling tile) aligned grid lines.

Determines visible lines, draws them. This is LineDef based, not LineSeg based.

Determines bounding box of all vertices, sets global variables controlling zoom range.

set the window scale to the minimum size

A_ReFire The player can re-fire the weapon without lowering it entirely.

SkullAttack Fly at the player like a missile.
