from mathlib_c import Vector, has been moved i guess?

Does vector object not have .DistTo anymore?

For where mathlib is now:

Hello,

could you fix this script, it's not working anymore. thanks in advance.

(Test it in HL2DM)

Syntax: Select all

from entities.entity import BaseEntity
from events import Event
from mathlib import Vector
from listeners.tick import tick_delays
from entities.helpers import create_entity
from engines.server import engine_server

@Event
def rpg_missile_detonate(game_event):
    
    # Create a particle system entity...
    particle = BaseEntity(create_entity('info_particle_system'))
    
    # Set its effect to an huge explosion...
    particle.effect_name = 'bomb_explosion_huge'
    
    # Set the origin of the particle...
    particle.set_key_value_vector('origin', Vector(*map(game_event.get_float, 'xyz')))
    
    # Precache the particle and set its index...
    particle.set_property_int('m_iEffectIndex', engine_server.precache_decal('bomb_explosion_huge'))
        
    # Start the particle effect...
    particle.Start()
    
    # Delete it later...
    tick_delays.delay(3, particle.Kill)

[satoon101]

Well, first, I don't believe rpg_missile_detonate is even an event, so you will need to find another way to know when this happens. To do that, you can use the following to show when an event is fired (if you have direct access to the server's console):

Code: Select all

sv_cheats 1
net_showevents 2

Second, we have changed the way inputs are called, so Start and Kill will not work:
http://forums.sourcepython.com/showthread.php?736

Lastly, I'm not sure if bomb_explosion_huge is a particle effect for HL2:DM, but I cannot remember how to get the particle effect dump L'In20Cible showed above.

[L'In20Cible]

Lastly, I'm not sure if bomb_explosion_huge is a particle effect for HL2 M, but I cannot remember how to get the particle effect dump L'In20Cible showed above.

That dump was the result of "dump_particlemanifest" but they removed that command, apparently.

However, that code is wrong. He need to add the effect to the ParticleEffectNames string table, not precaching it as a decal.

[satoon101]

That dump was the result of "dump_particlemanifest" but they removed that command, apparently.

Is there any other way we can access the particle names?

[L'In20Cible]

By hand, you could extract the file ../particles/particles_manifest.txt from the VPK directory and then decompile all the listed PCF files to see the specific names they are exporting. From a dynamic way, I will see what I can find in the binaries when I get the chance to. I remember I saw an interface to query particles in the SDK, could worth looking into exposing it.

Hey I made it work again with the following code:

Syntax: Select all

from entities.entity import BaseEntity
from entities.helpers import create_entity
from entities.helpers import spawn_entity

from players.entity import PlayerEntity
from players.helpers import index_from_userid

from events import Event
from listeners.tick import tick_delays

from stringtables import string_tables


@Event
def player_say(game_event):
    if game_event.get_string('text') != '!test':
        return
    # these are from hl2 pcf files:
    #blood_advisor_puncture_withdraw
    #embers_small_01
    #explosion_huge_burning_chunks
    userid = game_event.get_int('userid')
    index = index_from_userid(userid)
    player = PlayerEntity(index)
    player.targetname = 'player_%s'%userid
    particle = BaseEntity(create_entity('info_particle_system'))
    particle.set_key_value_string('Particle System Name', 'explosion_huge_burning_chunks')
    particle.origin = player.origin
    #particle.parentname = player.targetname
    particle.set_property_int('m_iEffectIndex', string_tables.ParticleEffectNames.add_string('explosion_huge_burning_chunks'))
    particle.call_input('SetParent', player.targetname)
    particle.call_input('Start')
    tick_delays.delay(3, particle.remove)

I'm trying now to attach the particle effect to a player so it's moving with the player but this code does not work. I also tried "SetParentAttachment" with the targetname.
Always gives me this error: Entity info_particle_system(info_particle_system) has bad parent player_2
Any ideas?

[L'In20Cible]

Try:

Syntax: Select all

particle.set_parent(player, -1)

[stonedegg]

Thanks, will test later. What is the -1 for?

[L'In20Cible]

The attachment index. For example, if you want to attach to the right foot of the player:

Syntax: Select all

particle.set_parent(player, player.lookup_attachment('rfoot'))

[stonedegg]

Ah nice, didn't know it works like that. Is there any way I can find all attachment points (and their indexes) of any entity? Tried googling, couldn't find anything.

[necavi]

Easiest way to do that from what I remember is to open the model in the HL Model Viewer, it lists the attachment points and shows you where they are on the model.

Okay, thanks!

The attachment index. For example, if you want to attach to the right foot of the player:

[python]particle.set_parent(player, player.lookup_attachment('rfoot'))[/python]

I've tried player.lookup_attachment() in hl2dm, but it returns always 0, whatever which argument I try. Any idea? Also is there a reason why this method does not exist in csgo?

[L'In20Cible]

I've tried player.lookup_attachment() in hl2dm, but it returns always 0, whatever which argument I try. Any idea?

The root (index 0) is returned if the given attachment name is not found.

Also is there a reason why this method does not exist in csgo?

No special reason, I simply didn't take the time to grab a signature for it yet.

[stonedegg]

Okay, well looks like the hl2mp player models are setup different then.

No special reason, I simply didn't take the time to grab a signature for it yet.

Ah okay, thought it wouldn't be possible or so.

Or dump them dynamically. :)

Still a work in progress so the syntax/names are subject to change but you get the idea.

Any way to make custom particles work in CS:S?

I tried uploading my *.pcf file to a client, but the client doesn't seem to recognize particle systems inside of it

You need to precache your pcf file:

from engines.server import engine_server
from listeners import OnLevelInit

def on_level_init(map_name):
    engine_server.precache_generic('file.pcf', True)
