Hello. i wanna share a few source code tweaks.. i'm very noob when it comes to programming so these are just copy-paste from other parts of sauer
to fulfill a role and they concern ctf sounds and a few changes to rifle trail. also i'm not gonna include some sauerbraten.exe cause i messed
my source at some point and water rendering is messed up in my game and i dont remember what i messed up :P oh you must compile the game
for these to work. if you're on windows download (if you're on linux or mac.. good luck :P no idea)
code::blocks (http://www.codeblocks.org/downloads) no idea which one is needed, i got mingw-setup.exe
and tdm64-gcc (http://tdm-gcc.tdragon.net/download)
once u install both open code::blocks and click settings->compiler. go to the Toolchain executables tab and point the Compiler's installation directory
to wherever u installed tdm64-gcc, e.g C:Program FilesMinGW64. Below that delete the prefixes of (mingw32-) was it? dont remember.. so you're left with gcc.exe g++.exe, g++.exe. (not sure if you have to do this last part, i just read it in some tutorial). then open sauerbraten directorysrcvcppsauerbraten.cbp with code blocks
and you're set!

Now to the tweaks.. the ctf sounds. i added different sounds for red and blue flag drops, returns, captures, and stolen. (personally i stole the ones from xonotic
cuz i like them :)) but you can use whatever you want. i'm not gonna give some link for you to download them cuz i've seen some folks in quadropolis
very uptight about licences and stuff, and since i couldnt care less about licences i just wont bother.

go to srcfpsgamegame.h at around line 170 you'll find
enum
{
S_JUMP = 0, S_LAND, S_RIFLE, S_PUNCH1, S_SG, S_CG,
...
}
scroll down to where it says
S_FLAGPICKUP,
S_FLAGDROP,
S_FLAGRETURN,
S_FLAGSCORE,
S_FLAGRESET,
now, you either add 4 (or 5 if you want different FLAG_RESET) more lines underneath them or above them like this (random names you can pick whatever you want (no spaces))
S_FLAGPICKUP,
S_FLAGDROP,
S_FLAGRETURN,
S_FLAGSCORE,
S_FLAGRESET,
S_REDPICKUP, // this is gonna be the sound pointer to the red flag stolen announcement
S_REDDROP, // this to red flag dropped.. etc
S_REDRETURN,
S_REDSCORE,
S_REDRESET,
obviously the already existing ones are gonna be used for the BLUE announcements respectively.
Then go to fpsentctf.h at around line 464 where it says
static const int sounds[] = { S_FLAGPICKUP, S_FLAGDROP, S_FLAGRETURN, S_FLAGSCORE, S_FLAGRESET, S_FLAGFAIL };
and fill it with the ones you added in game.h like this:
static const int sounds[] = { S_FLAGPICKUP, S_FLAGDROP, S_FLAGRETURN, S_FLAGSCORE, S_FLAGRESET, S_FLAGFAIL, S_REDPICKUP,S_REDDROP,S_REDRETURN,S_REDSCORE,S_REDRESET};
Next search for "playsound" without quotes in code::blocks to get a general list about the lines we'll need to change in ctf.h
the first hit is:
playsound(S_FLAGDROP);
which is the sound that plays when a flag drops! now you can either comment this line like this
//playsound(S_FLAGDROP);
and write the new one below or above it, or replace it with the new one which is:

playsound(flags[i].team==ctfteamflag(player1->team) ? S_FLAGDROP : S_REDDROP);

Trivia: if the statement-comparison in parentheses before the question mark is true, then it plays the sound S_FLAGDROP which we assigned (in our heads) to be for
the blue flag, otherwise it plays the sound S_REDDROP.

You're gonna do the same with all playsound lines in ctf.h except for the line 869:
playsound(team==ctfteamflag(player1->team) ? S_FLAGSCORE : S_FLAGFAIL);

in which you're just gonna change the corresponsing sounds. (S_FLAGSCORE for blue score and the other for red score).

Your sounds are stored in your sauerbraten directorypackagessounds
that is where sounds.cfg reads the location of sounds.. eg registersound "ctf/flagpickup" means there is a sound named flagpickup.wav in sauerbraten directorypackagessoundsctf
Next you open your sauerbraten directorydatasounds.cfg and scroll down to where it says:

registersound "ctf/flagpickup" //sound for blue flag pickup
registersound "ctf/flagdrop" //sound for blue flag drop.. etc
registersound "ctf/flagreturn"
registersound "ctf/flagscore"
registersound "ctf/flagreturn"

Then you replace the "flagpickup, flagdrop, flagreturn..." part with the name of the new sound file.
Afterwards you add these lines right below it (IF you added them in the order i mention before in game.h)
assuming you have sounds named redpickup.wav, reddrop.wav, etc... in your sauerbraten directorypackagessoundsctf otherwise replace accordingly.

registersound "ctf/redpickup" //sound for red flag pickup
registersound "ctf/reddrop" //sound for red flag drop.. etc
registersound "ctf/redreturn"
registersound "ctf/redscore"
registersound "ctf/redreturn"

And thats all about the sounds! Now about the rifle trail tweaks...

open srcfpsgameweapons.cpp and go to line 627:

particle_trail(PART_SMOKE, 500, hudgunorigin(gun, from, to, d), to, 0x404040, 0.6f, 20);

Here you can change some qualities of the particle trail of the rifle (smoke trail). Now i'll explain a few things:
--the first slot (PART_SMOKE) i'm not sure what it is.. i think it points to a smoke.png where it is spiraled around the axis of your gun->target. Maybe you can change it to something like PART_FLAME or PART_SNOW if you like.
--the second slot (500) is the duration of the smoke before it dissapears from the moment you fire in milliseconds, tweak to your liking!
--the third and fourth slots (hudgunorigin(gun, from, to, d)), to) we'll ignore cuz i dunno what they do and i dont think there is anything to tweak here :P
--the fifth slot is the color of the smoke! 0x[RED][GREEN][BLUE] 2 digits per color(0-9 and then A=10,B=11,C=12,D=13,E=14,F=15) google for "hex colors" to find something you like or.. stay tuned for random!
--the sixth slot is the diameter of the smoke and you can tweak it in this format: x.yf where x,y numbers of your choice.
and the last is the gravity.. dunno if anyone noticed (i hadnt until i changed it) for positive numbers the trail goes down, 0 = no gravity and negative numbers smoke goes up.

if you want random colors (yay!) you add this code below the "case GUN_RIFLE:" line 625

char bufferrr[15];
long kk = rnd(16777216);
itoa(kk, bufferrr, 16); //i think this converts integers from decimal form to their hexademical

Not sure what this does programmatically speaking.. but it gives us random colors! so replace the fifth slot (the one with the 0xFFFFFF with the variable kk
and you and everyone else gets random colors with every shot!

of course you, like me, may want just different smoke colors for your team and the enemy team.
add this code below the "case GUN_RIFLE:" line 625

int teamsmoke;
(isteam(d->team, player1->team)) ? popo=0x0789FC : popo=0xFC0907;

Comment out the previous code (for random colors) and replace in the fifth slot the variable teamsmoke

Want 3 smokes, one in middle one going up and one going down? copy the particle_trail.... line and paste it below it 2 times. change the last slot (gravity) to
-20, 0, 20 one in each line.
Maybe you like to shoot lightnings? we borrow the pistol ray trail and tweak it.
Comment out the particle_trail line.
copy paste right above or below it this line:

particle_flare(hudgunorigin(gun, from, to, d), to, 600, PART_STREAK, 0xFFC864, 0.28f);

you can tweak it just like the particle_trail if you want. and if you want the lightning replace the PART_STREAK with PART_LIGHTNING and remove the last slot like this
0xFFC864, 0.28f); ----> 0xFFC864); because it messes things up if you use the lightning.

Thats all folks maybe some day i search how to make these changeable by GUI but i'm probably lazy. cheers
oh and get the sauerfr mod it rox.

#10: more stuff

by chark on 11/06/2013 03:07

Hello again, i added more options and polished the menu. windows download, screenshots and source code links at the end.
i managed to squeeze everything in one tab (in the menu)
notes: removed xcode folder from source because its 70 mb, no idea if its needed for mac people.
if you download the zip, you start the game from sauerbraten_colors.bat. also, i set the sound.cfg to load from someMod/sound.cfg folder to minimize overwritting stuff (in main.cpp)
if you use the code in the zip, search in the project for "extra code begins here" and/or "extra code ends here"
also you need to get your own sounds for flag drops, returns etc. they're set to default sounds in someMod/sounds.cfg
if you already have an autoexec.cfg dont overwrite it, just copy the contents to yours... but if you have, you probably already know that :P

known bugs/problems: when playing with bots and the flag is picked by one of them, the game sometimes crashes, nothing in the log, just closes the game
if anyone figures out why please share :)
when you open the menu for first time all sliders for colors are at 0 and because of that an error is spammed: unknown alias lookup: bla.
so move all color sliders to something other than zero and restart game.. or dont, just dont play with bots until you do :P

the friend notifier i mention in the code is disabled in the zip cause you must put the name of your friend in the source, maybe if i learn
stuff about strings.. i might make a better one. by the way it notifies if friend enters/is on the same server as you.
tbh i dont know why there isnt such a thing in the official ;/

as i said feel free to do whatever you want with it

forgot to mention somewhere, that to install it just unzip in your sauerbraten installation folder
enjoy!
