radiant has a visible "edge" of the map in the 2d views, which made it easier to avoid this mistake. I guess in 3d it's hard to show this. TB2 will have 2d views, so this might be a nice feature to add. 

This means the smallest possible space they can spawn in is 40x40x64

oh? the padding is that much? 

Yes, 4 units on each side (same goes for monsters). Although, to be more correct, the minimum height is 60 as items can spawn on the floor. 

I tried to move the whole map at once, but not only did it made TB crash, but now the map is corrupted (it shows nothing and the console has this in red: "Malformed map file: expected token of type integer number, or decimal number, but found string at line 2629, column 65
".).

All this work go to waste in an instant. 

Protip: Backups, autosaves, multiple versions. 

Yes, now we get to have a teaching moment about back ups and file revisions ... 

Well, what's at line 2629, column 65 in the map file? 

I can just download a backup from my mediafire and refix the leaks.

But why in the hell did TB crashed when I was just trying to move everything and how can I center the map if there's no option for it? 

"( 1600 -1840 -0 ) ( 1600 -1840 176 ) ( 1552 -1840 -0 ) tech07_1 1.#QNAN 1.#QNAN 1.#QNAN 1.#QNAN 1.#QNAN" 

Replace all #QNANs with 0.

SleepwalkR explain yourself! 

How can I make monsters drop ammo/weapons? I've seen people comment on it but now how to make it work. 

...And most of the brushes and entities have moved away to some units, making the map a whole mess. 

"SleepwalkR explain yourself!"

LOL, your software crashed. N00b... 

Auto backups every few minutes - look inside your maps folder for a subfolder called 'autosave'.

FYI NAN is 'Not A valid Number' so even though 0 is a valid number, its almost certainly not the right one for that particular coordinate.
Monsters can only drop what they were told to carry by Qc, although Preach might have a hack for it: http://www.celephais.net/board/view_thread.php?id=37116&start=295

But in general without qc or hacks monsters only drop what they always have. 

Found the version of my map without the leaks and before the corruption.

This following thread says having monsters drop ammo/weapons is possible without qc amnipulation: http://www.celephais.net/board/view_thread.php?id=37116

And I'm still looking for a way to center my map without crashing TB. 

In that thread, with only hacking, there is the trick for making a monster that usually drops a backpack, having inside the backpack other ammo/health and weapons. There is also the trick to make a trigger drop items at an specific point.

But i suppose that what Daya want is to make a monster like the demon or the hell knight drop a quad, a key, a backpack or any other item when it dies with just hacking. And for that one, i have no idea.

By the way, now that we are talking about dropping things. Is there a way with just hacking to make a monster drop an item each time its hit (including enemies droping the backpacks that usually drop on death but droping the same one everytime they are hit), to create something like in the bonus stages in Golden Axe. 

A round about theory could be to keep the monster in the same place, use a trigger_once covering the enemy to count the damage and to trigger the item spawning, and then pass the damage to the monster with a trigger_hurt. It doesn't seem to be feasible but its an idea. 

...can it be set to follow it, so that if the monsters move, when he dies the item spawns on him?

you would RTFM. Necros and I went through a lot of trouble to provide TB with proper docs. The autosave is clearly explained in there.

Crashes: Well, shit. There's your explanation. 

 

 

I was careful enough with the other items which showed up this time by placing them somewhere else or giving them more space, but I tried the same thing for the quad damage (located inside a corridor between 2 closed doors)by extending a little bit the width of the corridor, but still no dice.

Is it related to entity limitations? 

letting someone else have a look at the map file.
