NoInfighting prevents enemy friendly-fire damage

[Guest]

If NoInfighting is set for a map in MAPINFO, enemies will be unable to harm each other with projectiles, as if they were of the same species.
In the attached example, the Imp and Cacodemon will not damage each other if they accidentally shoot one another.

Yes... And everything is fine, i think!
NoInfighting means... NoInfighting.

This is by design indeed.

Yes, it means no infighting, not 'no damage.' This is why hitscan attacks between enemies, such as two zombiemen, still do damage, but they don't begin to fight each other.

Monsters in this map will never turn on each other, even if they are hit by another monster's attacks which damage them.

This may not be detailed, but it is correct. The monsters in the map will never turn on each other. They may be hit by another monster's projectile - and, because of the noinfighting flag, this will not damage them. They may be hit by another monster's hitscan attack, which will damage them, but they will still not in-fight. In other words, monsters will never turn on each other, even if they are hit by another monster's attacks which damage them.

It's always been this way since the no infighting flag was a DEHACKED extension in ZDoom way back in the dim distant past.
