[Boom compat] change effect trigger

Hi,

In a Doomworld thread (https://www.doomworld.com/forum/topic/9 ... fic-sector) the question was asked how to create a triggerable secret tag for Boom-compatible ports. My suggestion was to turn the sector the player was standing on from normal to secret by using a 'change effect' trigger. See example level https://www.dropbox.com/s/z2eex38v2g4bk ... r.wad?dl=0. Two secrets: the red area counts as one; the blue area turns red & secret after pulling the switch.

That is, in PrBoom and Eternity. In (G)ZDoom this does not work. However, other sector flags (eg damage, friction) work as intended. The 'light' based flags might work, but they will not yield the intended result anyway in any port so I did not test that.

This was a fully intentional change because this behavior broke the secret counting in one of Heretic's IWAD maps.

Gotcha. Which Heretic map / area would that be?
