Solid Weapon Pickups

[Ghost_Fang]

I know if i want manual weapon pickups i have to make the standard quake weapons solid to be detected by the traceline. I don't see anywhere in items.qc where it tells the weapons to be SOLID_NOT. Or is it something completely different?

[Error]

all items are set solid in a seperate function:

Code: Select all

void() PlaceItem =
{
   local float   oldz;

   self.mdl = self.model;      // so it can be restored on respawn
   self.flags = FL_ITEM;      // make extra wide
   self.solid = SOLID_TRIGGER;
   self.movetype = MOVETYPE_TOSS;   
   self.velocity = '0 0 0';
   self.origin_z = self.origin_z + 6;
   oldz = self.origin_z;
   if (!droptofloor())
   {
      dprint ("Bonus item fell out of level at ");
      dprint (vtos(self.origin));
      dprint ("\n");
      remove(self);
      return;
   }
};


and for regenerating weapons/ammo and such it's done in this function:

Code: Select all

void() SUB_regen =
{
   self.model = self.mdl;      // restore original model
   self.solid = SOLID_TRIGGER;   // allow it to be touched again
   sound (self, CHAN_VOICE, "items/itembk2.wav", 1, ATTN_NORM);   // play respawn sound
   setorigin (self, self.origin);
};

weapons are SOLID_TRIGGER, so you can walk through them, but they still get touch notifications from players that walk inside them.

actually solid pickups will block the player's motion as well. consider using SOLID_CORPSE if your engine supports that.
failing that, you could use find and a traceline that succeeds when it reaches the center of the pickup without hitting anything.
note that to do that, you should probably make all such pickups use a single classname.

Can't you, before the user does the traceline, make them solid, then after, make them untouchabale again?

Or, you could like, use the same method I used to make a UT style shock rifle.

DO NOT play with solid, it is not necessary.

Just make a little hack:

In weapons.qc/ImpulseCommands add 2 lines

Code: Select all

   if (self.impulse == 213) // Any impulse number
      self.use_time = time + 0.2 // time to allow item pick-up


and in items.qc/weapon_touch:

Code: Select all

// after lines
   if (!(other.flags & FL_CLIENT))
      return;
// insert next two      
   if (other.use_time > time)
      return;


Also you need to define float .use_time somewhere.
To allow player use by impulse doors/buttons etc. just insert [if use_time] construction.

and... bind KEY "impulse 213" in config is very useful )

I think it would be best if the entity was kept non-solid and the findradius function was used instead, so you don't even have to look at it, just be near it..

I was thinking the same thing.

...and you can check direction

[Spike]

makevectors(self.v_angle);
if ((v_forward * normalize(ent.origin - self.origin)) > 0.5)
SelfIsFacingTowardsEnt();

Did you make all those maps on your site, Scrama?

I've always wondered how a static number of weapons provided on a map, with the limit of 1 weapon at a time in inventory would play out. I guess, with a balanced arsenal it could be viable.
Imagine everyone spawns with SG (axe well thats always there).
Other weapons spawn normally. If someone wants the new weapon they have to drop the old one. weapons do not respawn but are taken from a fallen enemy, thus forcing you to drop the weapon you had in hand that u used to kill that enemy.

hmm then again this might only be a good idea for an FFA game, otherwise you'll yell at your teammate "I want the RL!"

something like RUNES, only nothing like that

2Spike: exactly!

Sounds like offtopic, but yes, I am the autor )

like Counter-strike. BTW it is a good idea to limit player's arsenal in SP to 2-3 weapons at 1 time, not 1.

for teamplay how about allowing 1 instance of a weapon PER TEAM.
so each team can have a lightning gun...but a team cant have 2 (and you wont end up with 4 lightning guns on one team in a 4v4 scenario)
