[ZScript] Order in Events intentionally different?

[gwHero]

Hi,
since I couldn't find the answer on the wiki and the several topics concerning ZScript EventHandlers, I'll post my question here.

I was surprised to find out that the PlayerEntered event is called BEFORE the WorldLoaded event.
Is this intentionally different from their ACS counterparts, where ENTER is called AFTER the OPEN event?

It's of course not a problem, but quite fundamental to know if this shift in order is indeed as designed.

This is because the player enters a map BEFORE it is fully loaded - the player spawn is part of loading the map.
The reason why ACS is different is, because ACS scripts are not run when being requested, but later when the ACS thinker performs its first thinking turn and has a chance to do a bit of ordering.

Thanks for answering, it's good to know for migrating from ACS to ZScript to keep this in mind.

Out of curiousity, because this may or may not relate to something I was thinking of, does this mean we can use zscript to affect things such as slopes and other stuff that used to be the exclusive domain of map definition? It would be cool to add slopes to existing doom maps ingame.
