This time there was one important exported script function: Actor.Spawn.
Since this will require a level pointer in the new scheme of things the old version had to be deprecated, because it is static with no argument that allows retrieving the level. However, since this is probably one of the most widely used functions I added a workaround to let it continue to work if used from inside an actor class, which should constitute >95% of all uses. This required a little bit of hackery in the compiler backend to swap out the function if appropriate.
Aside from that there were 5 places in the internal ZScript that needed handling, which mostly consisted of making a formerly static internal function non-static.
Many uses of random() & value have been turned into random(0, value).
This is not only more efficient, it also ensures better random distribution because the parameter-less variant only returns values between 0 and 255.
In both cases, having this flag on will render the monster-backing-off-check for melee attacks ineffective because it would misinterpret these weapons as close range only - which they aren't. Even for the PhoenixRod the range is longer than what gets checked here.
As a consequence, the bot's check for missile shooting melee weapons has also become pointless because no such weapon is defined anymore.
The problem here is that this affects the public scripting interface so it cannot be committed to master without further adjustments.

DamageMobj can destroy the damaged actor if the death state sequence has zero duration. But Actor.target is a garbage collected member variable, i.e. it will be null, once the actor it points to gets destroyed.
This was originally done correctly in the C++ code but during the scriptification all those 'AActor *target = self->target' lines were removed because they looked redundant, but were not.
- changed the effect spawn prevention of the Hexen flame strike weapon and reverted the attempt to fix this in FastProjectile.
This cannot be fixed in the base class, which was doing everything right. It's the flame missile that was doing undefined things by stopping its movement without clearing its missile flag. This cannot work because missiles are given some minimal forced velocity to ensure collision detection and any attempt to address this without clearing the missile flag is doomed to fail.
This function calculated everything correctly but ultimately set the vertical velocity wrong. Most importantly this meant that the actual velocity vector and actor pitch - if CMF_SAVEPITCH was used - did not match.
Since this bug has been present since the pitch parameter was added, this deprecates A_CustomMissile and replaces it with a properly implemented A_SpawnProjectile function and handling the compatibility case with a new flag and a scripted wrapper function.
All internal uses of A_CustomMissile have been replaced as well.
For most attack functions this is wrong, it's only the Hexen fighter attack needing this particular value, so it has been split up into two return values now.
- merged the FrontBlock searcher for the Bloodscourge into RoughMonsterSearch. This also fixes the bug that the searcher was not initialized properly for the MageBoss.
