Yet another Doom2 HOM fix (Map21)

[Rachael]

This one really bugs me. This is a horrendous mapping error where 3 distinct sectors are referenced in a single plane - two of which clearly should not be there and were possibly intended to be deleted by Sandy Petersen when he designed it (but - buggy tools, stuff...).

Code: Select all

EBDAC00E9D25D884B2C8F4B1F0390539 // doom2.wad map21
{
	// push ceiling down in glitchy sectors above the stair switches
	setsectoroffset 50 ceil -56
	setsectoroffset 54 ceil -56
}

This fix doesn't patch up the 3-sector issue (I suspect creating any supporting directives for this would require a node rebuild at the very least), but it at least makes them all the same height so that the problem becomes invisible.

There's a comparable glitch in Strife's MAP10 on the shooting range, btw.

About the cause - remember how the original editor worked: All sector properties had to be put on linedefs and then let a tool create the sectors. It's just a perfect recipe for this type of error.

It seems that S:VE fixed this bug themselves by patching in a new MAP10.

At least it gives me a baseline for how I should do the compatibility.txt version of those fixes.

Yes. SVE fixed most of Strife's mapping bugs
