[page=Introduction]
This tutorial takes about 20 seconds, but it is REALLY helpful for those ultimate destruction mods, or a tourney mod.
[page=Making The Change]
Head on over to p_client.c, ClientBeginDeathmatch, which checks for respawns and resets all needed info. Right after the definitons, add this in:
// Do this to add 3 seconds worth of invincibility.
self->client->invincible_framenum = level.framenum + 30; // 10 frames per second.Change 30 to whatever your hearts desire. 30 = 3, just add a 10 to the desired number. Using Invulnerability item gives you 300 seconds of it.
There you go. Mess around with it. This can be used with Quad too!

You should add how to make this a CVar. Other than that, awsome.
Define your cvar in g_main.c:
cvar_t *respawn_protect; // admin configurable respawn protection
Set it to a reasonable default value in g_save.c:
// the DM respawn invulnerability (defaults to 5 seconds)
respawn_protect = gi.cvar("respawn_protect", "5", 0); //QW// allow admin to control respawn invincibility time
Do some checking of it's value periodically, perhaps in CheckDMRules() to keep it somewhat sane.
if (respawn_protect->modified || initialization) {
//limit value ranges allowed for the respawn protection
if (respawn_protect->value <= 0) gi.cvar_set("respawn_protect","0");
if (respawn_protect->value >= 6) gi.cvar_set("respawn_protect","6");
respawn_protect->modified = false;
}
Setting the spawn protection properly belongs in PutClientInServer():
// start invulnerable for variable seconds in DM, but not teamplay.
if (deathmatch->value && !ctf->value) {
int spawntime;
spawntime = (int) (respawn_protect->value * 10);
ent->client->invincible_framenum = level.framenum + spawntime;
}
If your mod doesn't have a CTF mode then you can eliminate the checks for them:
int spawntime;
spawntime = (int) (respawn_protect->value * 10);
ent->client->invincible_framenum = level.framenum + spawntime;
Note that invincible_framenum and spawntime are integers and respawn_protect->value is a float so we cast it to int to shut the compiler up about the conversion.
