Bug #740
Bullets not visible in map cheat
100%
Description
When you enable the map cheat to reveal all of the objects in Doom, you can also see where your bullets/shells/rockets/cells are fired.
In the 1.9.0 beta series, however, the bullets fired are not visible on the map when the cheat is on. Is this a bug or is this disabled because of the fact that the automap is overlayed right over the gameplay?

Updated by Bullets are not currently visible in the automap because the render algorithm for which has been changed (not strictly speaking a bug).
Historically, all sector-linked mobjs would be drawn by simply traversing the sectors and drawing (near) all mobjs in each sector. The new algorithm makes use of the blockmap for world to screen-space clipping purposes which necessarily means that for mobjs to be drawn they must be block-linked (missile mobjs aren't).
Two solutions to this problem immediately spring to mind:
A) Revert to the original (inefficient) automap mobj drawing algorithm.
B) Revise the blockmap mobj linking so that ALL mobjs are linked to the blockmap and the Thing flag MF_NOBLOCKMAP is instead interpreted as a qualifier flag (meaning "cannot be collided with") that is checked during blockmap traversal (the qualifier flags provided as an argument or used in a game-defineable compare callback function).
Personally, I much prefer option B).
