If you want a message to stay on the screen longer, you can string multiple triggers with delays containing the same message.

Add \n to start a new line if a message becomes too long.

Not sure what you are asking but that's a start for messages in vanilla Quake. 

Key 'message'
Data 'whatever you want to say' 

I need advice.

What's the appropriate combat for a maze-like map? I mean, in a set of interconnected hallways how encounters should be? 

Every ten seconds, two front spawns and three back spawns in bbox contact with the player. 

What Kinn said. 

 

I believe he said spawns... ;) 

 

OK, im working in it now 

So rare, I add a specific in a trigger in QuArK and it does not able, but I make again in TB and it does work. Im yet working... 

It's normal that QuArK finds holes in the map without being it? I brushing in TB but when I open QuArK to Qbsp and test, sometimes said "there is a hole in your map" and time later I do not move any brush, I change a trigger config and it back to Works in qbsp. 

Quark stores no floater points on brushes, so every time reloading the map it slightly differ integers. So mostly there is that message.

Better take a "better" editor, took time to use GtkRadiant or TB.
There is the option to select all verts and force them to grit. 

1. In such a way you think it'll be fun.

2. Play map.

3. Alt tab out if you think of a way it could be more fun.

4. Make change in editor.

5. Alt tab back to game.

6. Repeat step 3.

7. Once level is complete, recompile.

1. Repeat from 1.

This is the recipe for getting good. 

MadFox: GtkRaadiant have visible grid lines? 

 

i just fill every available space with monsters. 

 

what trigger I need for an Introduction changelevel???...... or what specific???... 

But actually you all ended up giving me an idea. Let's see if it works.

Also, what Qmaster said. 

GtkRadiant1.4 has several coloured grid settings, I prefer white lines on black.

Introduction changelevel?
Put in a trigger_multiple, add a corresponding trigger brush, and fill in a short message.
Or if you ment tigger_changelevel and fill in the map you want to continue with, e1m2. 

When you enter to a level from start.bsp, appears "loading".
But when you enter from a single map, appears "kills 13/13, secrets 2/3".

I don't know what to put in the Introduction(start) for going to e1m1. 

Yeah, start.map has no intermission screen. How does that work again? 

I think it's "spawnflags" "1" on the trigger_changelevel for no intermission 

"Intermission": Solved trouble!
that's I complicate me with the language.
I use google trans but I don't believe so much in it. 

... apparently. I could have sworn that when I previously made a brush into a func_door in TB, it would move (or "open") when the player approached it if I didn't tinker with the default entity values.

Now I've just made two bog-standard door-shaped brushes inside an arch and turned both into func_door, and when my player character approaches or even touches them, nothing happens. Each func_door is 64 units wide and "lip" is set to 8. I've tried changing "lip" to a different value and changing "angle" to a different value, but to no avail. Am I missing something obvious?
