Sticky: Q2 Weapons/Items FAQ

[Whirlingdervish]

I was given this link by a buddy of mine, to a very well made little website that has
lots of in depth info about the weapons and armor and items in Q2 and how they all work..

http://www.quake2.com/q2wfaq/q2wfaq.html

Most of it you probably know, but I found a couple things that surprised me.

Nice

[X'tyfe]

is this something that really needs an FAQ? i know there are still nubs
but holy shit even the dumbest of dumb asses could figure out how to point and shoot

white box with red cross is for big ouchies!!

Even though, it's interesting to be able to note the exact formulae and values of things, so you can more accurately gauge things.

[peewee_RotA]

There's some issues with certain things. Mostly typo's however he does get everything accurate enough to help.

First thing is that he didn't mention hyperblaster wind up which is the sole reason why the weapon is as low on the food chain as it is.

Next the chaingun does 1-2 shots perframe at random during windup and 2-3 shots per frame during full fire. This changes the damage per second to a variable and not an exact number.

Also the machinegun does only 4 damage in deathmatch. I'm certain it's the same in SP but am not really interested in checking.
machingun & shotgun =4dmg per bullet effect
Chaing & SSG = 6dmg per bullet effect

The last typo involved the bandolier. It gives you 10 shells not cells.

He also didn't really bother to mention the addition method for armor. Simply put you get 1/3rd the armor you would normally when you go down a level. If you have combat and pick up jacket you recieve .30 of the armor normally. Same with combat while using body. And picking up jacket while using body gives you about 1/6th of the total. (I don't remember exactly how they calculate it)


Other than that the info on BFG and power shield was very well explained. They are not easy calculations to understand from the code let alone explain so well.

I know this is somewhat gravedigging, but I thought I'd open the explanation a little bit on how armor calculation is done.

Each armor in Q2 is given different types of protection and counts. These are the values for the base armors:

Name	Base Count	Max Count	Normal Protection (%)	Energy Protection (%)
Jacket Armor	25	50	30	0
Combat Armor	50	100	60	30
Body Armor	100	200	80	60

When you get shot, this is the CleanCode representation for how armor is checked:

Code: [Select]

int CArmor::CheckArmor (CPlayerEntity *Player, vec3_t point, vec3_t normal, int damage, int dflags)
{
if (!damage)
return 0;
if (dflags & DAMAGE_NO_ARMOR)
return 0;

int save = ceil (((dflags & DAMAGE_ENERGY) ? ((float)energyProtection / 100) : ((float)normalProtection / 100)) * damage);
if (save >= Player->Client.pers.Inventory.Has(this))
save = Player->Client.pers.Inventory.Has(this);

if (!save)
return 0;

Player->Client.pers.Inventory.Remove(GetIndex(), save);
CTempEnt_Splashes::Sparks (point, normal, (dflags & DAMAGE_BULLET) ? CTempEnt_Splashes::STBulletSparks : CTempEnt_Splashes::STSparks, CTempEnt_Splashes::SPTSparks);

// Ran out of armor?
if (!Player->Client.pers.Inventory.Has(this))
Player->Client.pers.Armor = NULL;

return save;
}

And here's the code for picking up:

Code: [Select]

bool CArmor::Pickup (edict_t *ent, CPlayerEntity *other)
{
if (normalProtection == -1)
{
if (other->Client.pers.Armor == NULL)
{
other->Client.pers.Inventory.Set (NItems::JacketArmor, 2);
other->Client.pers.Armor = dynamic_cast<CArmor*>(NItems::JacketArmor);
}
else
{
if (maxCount != -1 && (other->Client.pers.Inventory.Has(other->Client.pers.Armor) >= maxCount))
return false;

other->Client.pers.Inventory.Add (other->Client.pers.Armor, 2);
if (maxCount != -1 && (other->Client.pers.Inventory.Has(other->Client.pers.Armor) > maxCount))
other->Client.pers.Inventory.Set(other->Client.pers.Armor, maxCount);
}
if (!(ent->spawnflags & DROPPED_ITEM) && (game.mode & GAME_DEATHMATCH))
SetRespawn (ent, 20);
return true;
}

if (other->Client.pers.Armor != NULL)
{
if (normalProtection > other->Client.pers.Armor->normalProtection)
{
// calc new armor values
int newCount = baseCount + (((float)other->Client.pers.Armor->normalProtection / (float)normalProtection) * other->Client.pers.Inventory.Has(other->Client.pers.Armor));
if (newCount > maxCount)
newCount = maxCount;

// zero count of old armor so it goes away
other->Client.pers.Inventory.Set(other->Client.pers.Armor, 0);

// change armor to new item with computed value
other->Client.pers.Inventory.Set(this, newCount);
other->Client.pers.Armor = this;
}
else
{
// calc new armor values
int newCount = other->Client.pers.Inventory.Has(other->Client.pers.Armor) + (((float)normalProtection / (float)other->Client.pers.Armor->normalProtection) * this->baseCount);
if (newCount > other->Client.pers.Armor->maxCount)
newCount = other->Client.pers.Armor->maxCount;

// if we're already maxed out then we don't need the new armor
if (other->Client.pers.Inventory.Has(other->Client.pers.Armor) >= newCount)
return false;

// update current armor value
other->Client.pers.Inventory.Set(other->Client.pers.Armor, newCount);
}
}
// Player has no other armor, just use it
else
{
other->Client.pers.Armor = this;
other->Client.pers.Inventory.Set(this, baseCount);
}

if (!(ent->spawnflags & DROPPED_ITEM) && (game.mode & GAME_DEATHMATCH))
SetRespawn (ent, 20);

return true;
}

I know the code reps may not be easy to follow, but basically when you pick up armor with a lower normal protection, you salvage your armor's normal protection percentage of it.

Nifty little FAQ - but is incorrect about Adrenaline increasing your maximum health - this is true in single-player, but not in Deathmatch.

In DM, the Ancient Head will increase your max health by 2 points.  One Ancient Head will thus give you a max of 102% Health.  This also becomes the number your health attains when grabbing an Adrenaline.  I use this effect in Bubbles.bsp (Mutant) - there are two Ancient Heads, each layered 16x, so that they increase your max health by 32 - definitely a worthy goal, as it's nice when Adrenaline can give you, say, 164% health...
