Adding RF_SHELL effects to items: Part 1
 
This will show you how to add a colored shell to any spawned item. In this
example we will first give the shotgun a green shell then we will add a
colored shell to the ctf tech runes.
 
 
Open g_items.c and find the SpawnItem function.
Right after ent->s.renderfx = RF_GLOW; put:
 
 if (strcmp(ent->classname, "weapon_shotgun") == 0){
 ent->s.renderfx = RF_FULLBRIGHT;
 ent->s.effects |= EF_COLOR_SHELL;
 ent->s.renderfx |= RF_SHELL_GREEN;
 }
 
All this says is that if the spawned entity is the shotgun then give it a
SHELL that is the color GREEN. "weapon_shotgun" is the classname for the
shotgun... you can find classnames for other items in gitem_t itemlist[]
just below the SpawnItem function. 
 
 
If you want other items to have the same effect you could do this:
 
 if ((strcmp(ent->classname, "weapon_shotgun") == 0) || 
 (strcmp(ent->classname, "weapon_supershotgun") == 0)){
 ent->s.renderfx = RF_FULLBRIGHT;
  ent->s.effects |= EF_COLOR_SHELL;
 ent->s.renderfx |= RF_SHELL_GREEN;
 }
 
This says if the spawned item is a shotgun or or a supershotgun then give it
a SHELL that is the color GREEN.
 
 
If you want everything to have the above effect, then just get rid of the if
statement so that it looks like this:
 
 ent->s.renderfx = RF_FULLBRIGHT;
 ent->s.effects |= EF_COLOR_SHELL;
 ent->s.renderfx |= RF_SHELL_GREEN;
 
 
 
Adding colored shells to CTF tech runes: Part 2 (Requires CTF code)
 
Open g_ctf.c and find the SpawnTech function.
Right after ent->s.renderfx = RF_GLOW; put:
 
 ent->s.effects |= EF_COLOR_SHELL;
 if (strcmp(ent->classname, "item_tech1") == 0){
 ent->s.renderfx |= RF_SHELL_BLUE;
 }
 if (strcmp(ent->classname, "item_tech2") == 0){
 ent->s.renderfx |= RF_SHELL_RED;
 }
 if (strcmp(ent->classname, "item_tech3") == 0){
 ent->s.renderfx |= RF_SHELL_DOUBLE;
 }
 if (strcmp(ent->classname, "item_tech4") == 0){
 ent->s.renderfx |= RF_SHELL_GREEN;
 }
 
This does the same thing as the shotgun example with one exception... the
RF_FULLBRIGHT and EF_COLOR_SHELL are not in each if statement. Why...
because we plan on giving all etches a colored shell and we don't have to
repeat it four times!
 
 
Open g_items.c and find *Drop_Item function.
Right after dropped->s.renderfx = RF_GLOW; put:
 
 dropped->s.effects |= EF_COLOR_SHELL;
 if (strcmp(dropped->classname, "item_tech1") == 0){
 dropped->s.renderfx |= RF_SHELL_BLUE;
 }
 if (strcmp(dropped->classname, "item_tech2") == 0){
 dropped->s.renderfx |= RF_SHELL_RED;
 }
 if (strcmp(dropped->classname, "item_tech3") == 0){
 dropped->s.renderfx |= RF_SHELL_DOUBLE;
 }
 if (strcmp(dropped->classname, "item_tech4") == 0){
 dropped->s.renderfx |= RF_SHELL_GREEN;
 }
 
This will make sure the tech will have a colored shell after it has been
droped.
 
Here are the RF_SHELL colors:
RF_SHELL_BLUE
RF_SHELL_RED
RF_SHELL_GREEN
RF_SHELL_DOUBLE
RF_SHELL_HALF_DAM
