Hello guys,

sorry another Entity Create Topic.

Iam spawning a model with prop_physics_multiplayer.
On that spawned model (entity), i want to create an env_physexplosion entity which pushes in a certain radius every physic around.

My code so far:

Syntax: Select all

def pushEntities(entities, magnitude, radius):
    for entity in entities:
        physExplosionEnt = Entity.create('env_physexplosion')
        physExplosionEnt.origin = entity.origin
        physExplosionEnt.damage = 0
        physExplosionEnt.radius = radius
        physExplosionEnt.magnitude = magnitude
        physExplosionEnt.start = 1
        physExplosionEnt.explode = 1
        physExplosionEnt.spawn()


# Which are called like this:
    spawnedModels = spawnModels(models, [Vector(deathOrigin[0] - 10, deathOrigin[1] - 10, deathOrigin[2])])
    pushEntities(spawnedModels, 50000, 50000)

So the models are spawned correctly, the entity.origin is valid. Everything is ok.
It just hasn't the effect i want. Iam not sure if i forget a property to set.

Can someone help?
PS reversing the spawn then setting start & explode doesnt help aswell:

Syntax: Select all

physExplosionEnt.spawn()
physExplosionEnt.start = 1
physExplosionEnt.explode = 1

Here is a link to the doc:

Thank you very much!
Cheers,
CANi

It looks like we haven't added any CEnvExplosion values to our entity data:
https://github.com/Source-Python-Dev-Te ... n/entities

So setting the damage, radius, and magnitude attributes will not do anything. For now, you'll have to set those differently:

Syntax: Select all

physExplosionEnt.set_key_value_float('DamageForce', 0)
physExplosionEnt.set_key_value_int('iRadiusOverride', radius)
physExplosionEnt.set_key_value_int('iMagnitude', magnitude)

I don't see a "start" propery or keyvalue for the entity. For explode, that's an input, so you have to call it not set it. Again, for now, until we add these to our entity data, it will look like:

Syntax: Select all

physExplosionEnt.call_input('Explode')

If you want, take a look at this thread and feel free to add these to the entity data with a pull request:

Thank you for your answer.
Sadly, it's still not doing anything.

Here my current code:

Syntax: Select all

def pushEntities(entities, magnitude, radius, duration):
    for entity in entities:
        physExplosionEnt = Entity.create('env_physexplosion')
        physExplosionEnt.spawn_flags = 1
        physExplosionEnt.set_key_value_int('iRadiusOverride', radius)
        physExplosionEnt.set_key_value_int('iMagnitude', magnitude)
        physExplosionEnt.spawn()
        physExplosionEnt.origin = entity.origin
        #physExplosionEnt.teleport(entity.origin, None, None) #Needed?
        physExplosionEnt.call_input('Explode')

Do you see whats missing?

I found a archive file to the linked link in the docs of valve:
https://archive.is/YuIaZ

Does this help figuring out what to do?

Oh, sorry, I was looking at CEnvExplosion and not CPhysExplosion. The keyvalues are different:

Syntax: Select all

physExplosionEnt.set_key_value_int('radius', radius)
physExplosionEnt.set_key_value_int('magnitude', magnitude)

There's also a targetentityname keyvalue. So, you might need set the targetname of the entity you wish to push and the targetentityname of the env_physexplosion to some unique identifier.

Syntax: Select all

entity.targetname = physExplosionEnt.targetentityname = f'phys_{entity.index}'

Also, if this is for CS:GO and you only want this to fire once and then be removed, you can use the input ExplodeAndRemove. If it's a different game, you'll have to remove the entity after using the Explode input instead.

Now its working!
The only thing which isnt, is the targetentityname.

Are you sure it's phys_{entity.index}?

Iam spawning 'prop_physics_multiplayer'.
I tried to get the entities names by iterating through and printing the global_name, but that's empty.
How do you get the name of it?

The f'phys_{entity.index}' is just setting it uniquely. For instance, if the entity's index is 12, the targetname for the entity and the targetentityname for the env_physexplosion entity are set to phys_12. By default, I believe the targetname of any entity is set to an empty string. So, because you set it to phys_12, and the targetentityname of the env_physexplosion to phys_12, the env_physexplosion knows which entity to act upon.

I'm not sure what you mean by it isn't working, though.

Edit: note that the f prior to the string is very important:

Delete the last 2 posts & close the thread. Works,was my mistake.
Appreciated!
