HL2/HL2DM weapon laser

[daren adler]

Was wondering if a scripter could make a laser pistol, using (weapon_pistol) for a lasergun in my hl2 server ?, Thank you and have a great day.

Tomorrow(after work) or saturday i will make it.
Should the user who is wearing weapon: weapon_pistol only see the laser or everyone?
Also should it also make damage to victim(where the laser aims at)?
If makes damage, how much it would make damage then?

Everyone if you can please. and yes right where it points at, and the damage i would like just like the pistol (i think its damage is 15)

Try this(Untested):

Syntax: Select all

from effects import TempEntity
from engines.precache import Model
from entities.entity import Entity
from filters.players import PlayerIter
from listeners.tick import Repeat

def load():
    laser_aiming.start(repeat_timer)

def unload():
    laser_aiming.stop()

repeat_timer = 1.0 # How often timer is executed
laser_damage = 15 # How much damage does laser hit

laser_model = Model('sprites/laser.vmt')

laser_beam = TempEntity('BeamPoints')
laser_beam.red = 128
laser_beam.green = 0
laser_beam.blue	= 0
laser_beam.alpha = 255
laser_beam.life_time = repeat_timer
laser_beam.start_width = 3
laser_beam.end_width = 3
laser_beam.amplitude = 2
laser_beam.halo_index	= laser_model
laser_beam.model_index	= laser_model

@Repeat
def laser_aiming():
    for player in PlayerIter('alive'):
        weapon = player.get_active_weapon()
        if weapon is None:
            return

        classname = weapon.classname
        if classname != 'weapon_pistol':
            continue

        laser_beam.start_point = player.eye_location + player.view_vector
        laser_beam.end_point = player.get_view_coordinates()
        laser_beam.create()

        target = player.view_player
        if target is None:
            continue

        target.take_damage(damage=laser_damage, attacker_index=player.index, weapon_index=Entity.create_or_find('point_hurt').index)

Thank you very much but not working, i got this error

This should fix the error

No error, but this time it will not let the server come on, So i // blocked it or remove it and the server would start up.

[cssbestrpg]

try load it after server is on

[daren adler]

I understand what you are saying, but this is a rent server and not a home server, So i would not be able to do it that way, i only use WinSCP to add files and folders

[cssbestrpg]

my guess would be precaching vmt as global causes the problem, try this one:

Syntax: Select all

from effects import TempEntity
from engines.server import engine_server
from entities.entity import Entity
from filters.players import PlayerIter
from listeners.tick import Repeat

def load():
    laser_aiming.start(repeat_timer)

def unload():
    laser_aiming.stop()

repeat_timer = 1.0 # How often timer is executed
laser_damage = 15 # How much damage does laser hit


laser_beam = TempEntity('BeamPoints')
laser_beam.red = 128
laser_beam.green = 0
laser_beam.blue	= 0
laser_beam.alpha = 255
laser_beam.life_time = repeat_timer
laser_beam.start_width = 3
laser_beam.end_width = 3
laser_beam.amplitude = 2

@Repeat
def laser_aiming():
    laser_model = engine_server.precache_model('sprites/laser.vmt')
    for player in PlayerIter('alive'):
        weapon = player.get_active_weapon()
        if weapon is None:
            return

        classname = weapon.classname
        if classname != 'weapon_pistol':
            continue

        laser_beam.start_point = player.eye_location + player.view_vector
        laser_beam.end_point = player.get_view_coordinates()
        laser_beam.halo_index	= laser_model
        laser_beam.model_index	= laser_model    
        laser_beam.create()

        target = player.view_player
        if target is None:
            continue

        target.take_damage(damage=laser_damage, attacker_index=player.index, weapon_index=Entity.create_or_find('point_hurt').index)

Ok, works,, thank you very much.
