|
|
Is there a way to implement bot functions (AI, waypointing, ...) on a true client?
Let's say I'm playing QW DM and I want to get a beer?
Can I switch to auto-pilot until I get back? _________________ Welcome to the Overlook Hotel 69.113.123.178:27500 |

I imagine this could be done with CSQC for clients that support it and on servers that don't have any protection against third party CSQC progs.dat's, but that kind of thing is generally considered cheating, to my knowledge. _________________ woh... feelin woozy... too much cider...

You could do it serverside as well, which is easier to protect against cheating too. Just add a cvar check in say PlayerPreThink, or SV_PlayerPhysics, if on, run AI code on client. Not harder than making a regular bot. Which, ofcourse, is very hard  _________________ Look out for Twigboy |

nope, i'm currently without internet at home (i check this occassionally at work)
Redoing a heap of the core navigation stuff in shockbot at the moment. There's a bunch of things I want to make nicer, and how I was doing things was really limiting (pick a goal, then route to a goal).
Whereas with the new system, i should hopefully be able to get it working where it can know how to get to everything, then decide which one it wants to go for. The difference being that real travel distances can be taken into account rather than just a straight distance check to items. Also this will allow for a better way to do item respawn prediction.  _________________ Unit reporting!

Redrum, I just made a human bot.
BUT, it's not smart as a player, and it has perfect aim with instant weapons, so the shotguns and sniper rifle are undodgeable.
Impulse 150 will toggle between on and off.
It will respawn automatically when dead and will shoot the enemies.
Another thing is that he won't choose a weapon too, he'll fire with the current weapon until the ammo depletes.
I made it to be simple.
So let's do it.
Open world.qc and add this before StartFrame():
Code: |
float() FindEnemy =
{
local entity head;
head = findradius(self.origin, 2000);
while (head)
{
if (head != self)
if (!(head.flags & FL_ITEM))
if (head.health > 0)
if (head.takedamage == DAMAGE_AIM)
if (visible(head))
self.enemy = head;
head = head.chain;
}
if (self.enemy != world)
return TRUE;
return FALSE;
};
.float goleft, goright;
void() Autopilot =
{
if (self.health <= 0)
{
stuffcmd (self, "-forward\n");
stuffcmd (self, "-moveleft\n");
stuffcmd (self, "-moveright\n");
return;
}
self.fixangle = TRUE;
if (self.enemy == world)
{
if (FindEnemy())
return;
self.angles_x = 0;
stuffcmd (self, "+forward\n");
stuffcmd (self, "-moveleft\n");
stuffcmd (self, "-moveright\n");
if (random() < 0.02)
{
if (self.turndir == 45)
self.turndir = -45;
else
self.turndir = 45;
}
traceline (self.origin, self.origin + v_forward*320, TRUE, self);
if (trace_fraction < 0.2)
self.angles_y = self.angles_y - self.turndir;
}
if (self.enemy != world)
{
if (self.enemy.health <= 0 || !visible(self.enemy))
{
self.enemy = world;
return;
}
stuffcmd (self, "-forward\n");
traceline (self.origin, self.origin + v_right*320, TRUE, self);
if (trace_fraction < 0.2)
{
self.goleft = TRUE;
self.goright = FALSE;
}
traceline (self.origin, self.origin - v_right*320, TRUE, self);
if (trace_fraction < 0.2)
{
self.goleft = FALSE;
self.goright = TRUE;
}
self.angles = vectoangles(self.enemy.origin - self.origin);
self.angles_x = self.angles_x * -1;
if (self.goleft)
{
stuffcmd (self, "+moveleft\n");
stuffcmd (self, "-moveright\n");
}
if (self.goright)
{
stuffcmd (self, "-moveleft\n");
stuffcmd (self, "+moveright\n");
}
if (infront(self.enemy) && self.attack_finished < time)
W_Attack ();
}
};
|
Ok, now add this at the very bottom of StartFrame(), before framecount line:
Code: |
local entity plr, oself;
plr = find(world, classname, "player");
while (plr != world)
{
if (plr.autopilot)
{
oself = self;
self = plr;
Autopilot ();
self = oself;
}
plr = find(plr, classname, "player");
}
|
Now go to the very top of world.qc, and add these 2 lines:
Code: |
float(entity targ) visible;
float(entity targ) infront;
|
Now save and close the file. Open defs.qc and add this to the very bottom:
Code: |
.float autopilot, turndir;
|
Save and close.
Now open client.qc, scroll down to PlayerPreThink() and find:
Code: |
if (self.deadflag >= DEAD_DEAD)
{
PlayerDeathThink ();
return;
}
|
Replace the whole statement with this:
Code: |
if (self.deadflag >= DEAD_DEAD)
{
if (self.autopilot)
{
respawn();
return;
}
PlayerDeathThink ();
return;
}
|
Now scroll up to PutClientInServer(), and add this before DecodeLevelParms():
Code: |
self.enemy = world;
self.turndir = 45;
|
Save and close client.qc and open player.qc, scroll down to player_nail1().
Replace these 4 functions with these:
Code: |
void() player_nail1 =[$nailatt1, player_nail2 ]
{
muzzleflash();
if (self.autopilot)
{
if (self.enemy == world || intermission_running || self.impulse || self.ammo_nails < 1)
{player_run ();return;}
}
else
{
if (!self.button0 || intermission_running || self.impulse || self.ammo_nails < 1)
{player_run ();return;}
}
self.weaponframe = self.weaponframe + 1;
if (self.weaponframe == 9)
self.weaponframe = 1;
SuperDamageSound();
W_FireSpikes (4);
self.attack_finished = time + .2;
self.fired_nails = self.fired_nails + 1;
};
void() player_nail2 =[$nailatt2, player_nail1 ]
{
muzzleflash();
if (self.autopilot)
{
if (self.enemy == world || intermission_running || self.impulse || self.ammo_nails < 1)
{player_run ();return;}
}
else
{
if (!self.button0 || intermission_running || self.impulse || self.ammo_nails < 1)
{player_run ();return;}
}
self.weaponframe = self.weaponframe + 1;
if (self.weaponframe == 9)
self.weaponframe = 1;
SuperDamageSound();
W_FireSpikes (-4);
self.attack_finished = time + .2;
self.fired_nails = self.fired_nails + 1;
};
//============================================================================
void() player_light1 =[$light1, player_light2 ]
{
muzzleflash();
if (self.autopilot)
{
if (self.enemy == world || intermission_running || self.impulse || self.ammo_cells < 1)
{player_run ();return;}
}
else
{
if (!self.button0 || intermission_running || self.impulse || self.ammo_cells < 1)
{player_run ();return;}
}
self.weaponframe = self.weaponframe + 1;
if (self.weaponframe == 5)
self.weaponframe = 1;
SuperDamageSound();
W_FireLightning();
self.attack_finished = time + 0.2;
};
void() player_light2 =[$light2, player_light1 ]
{
muzzleflash();
if (self.autopilot)
{
if (self.enemy == world || intermission_running || self.impulse || self.ammo_cells < 1)
{player_run ();return;}
}
else
{
if (!self.button0 || intermission_running || self.impulse || self.ammo_cells < 1)
{player_run ();return;}
}
self.weaponframe = self.weaponframe + 1;
if (self.weaponframe == 5)
self.weaponframe = 1;
SuperDamageSound();
W_FireLightning();
self.attack_finished = time + 0.2;
};
|
Lastly, save and close player.qc and open weapons.qc, add this to ImpulseCommands():
Code: |
if (self.impulse == 150)
{
if (!self.autopilot)
{
self.autopilot = 1;
sprint (self, PRINT_HIGH, "Autopilot engaged.\n");
}
else
{
self.autopilot = 0;
sprint (self, PRINT_HIGH, "Autopilot disengaged.\n");
stuffcmd (self, "-forward\n");
stuffcmd (self, "-moveleft\n");
stuffcmd (self, "-moveright\n");
}
}

Redrum (from work PC)
Orion, I made the necessary changes and it compiled
BUT, I got this error message when launching the server:
SV_Error: You must have the progs.dat from QuakeWorld installed
I do have that file. What's up? _________________ Welcome to the Overlook Hotel 69.113.123.178:27500 |

What the hell?
Did you test at work?
Your code could be different. Try at home.
I tested here and nothing happened. Really weird. _________________ There's no signature here. Stop looking for one. |

Means that the crc inside the progs.dat was not recognised for that platform. You get this error if you run an nq mod in a qw server.
The message should actually read 'qwprogs.dat'... The engine uses qwprogs.dat first if it can, and progs.dat after. But that's just a naming convention.
If it worked before, then you've probably wrongly modified defs.qc and added/removed/changed something before end_sys_fields. Restore the top two sections of that file to the previous version. _________________ What's a signature? |

Only modified defs.qc at the bottom though? _________________ Welcome to the Overlook Hotel 69.113.123.178:27500 |
