Physical dimension limits in maps

Doombuilder appears to have no real limit to a map's physical size (not number of sectors or linedefs, etc); but how far in each quadrant would be a safe limit for the zdoom engine and Doombuilder in general? Would +/- 32,000 points on the grid (a map within a 64,000 grid area) be too much for the engines to handle or would the map be stable?

I'd recommend staying well within those limits. I've heard horror stories about precision breakdown near the +/- 32,000 limit.

So would a safe limit fall more in the lines of +/- 20,000 in your understanding? Or would +/- 25,000 be out of reach of horror storyland? I don't want to run any risks.

Best stay below +-24000 and don't use more than 32767 in one direction altogether. If a map gets larger there can be fixed point overflow issues that create really strange effects.

Personally, my maps just crashes if it gets too big. How did the Alien Vendetta team make those huge maps anyway? Are they within the limit? They seem to be much larger.

DBuilder for me just crashes when a line gets too long

Then dont make lines that long! If you make a line that long in DB that makes it crash, you may as well be a dumbass

To do that I just make 2 lines connected

I've worked on some really huge maps before (ZDCMP2 before the whole hubbing deal is a good example) and after a certain amount of linedefs or sidedefs were reached it stopped working properly, and after a certain size DB couldn't build nodes for it, but the only size problem I know of are the statistics limits.

Of course, I've never gone past the physical size that Graf's specified, so that makes sense.

@Eriance: They look well within the limti to me. Maps can be larger than that easily, like the ZDCMP maps. I think I might have outsized most of AV's maps with a certain map I've made and released.

The only problem AV had was with map20 if you've allocated more memory with the -maxdemo param. Only an issue in full 30 map runs.
