On Prop +use from Player

[Predz]

I am trying to hook onto the "use" function available when a player uses "+use" on a prop of any kind. The hook works perfectly however the arguments returned are of the Entity itself, and another that I cannot obtain info on. The returned arguments are (Pointer, Pointer), the first being the Entity, the second I hoped would be the Player. On my tests the server just crashes upon trying to obtain a index from said pointer. Code is beneath:

Syntax: Select all

from engines.precache import Model
from messages import SayText2
from players.entity import Player
from players.helpers import index_from_userid
from entities.entity import Entity
from entities.hooks import EntityPreHook
from entities.hooks import EntityCondition
from events import Event
from memory import make_object

model = Model('models/props/cs_militia/toilet.mdl')

global index

@Event('player_say')
def _on_say(event):
	player = Player(index_from_userid(event['userid']))
	origin = player.view_coordinates
	
	entity = Entity.create('prop_physics_override')
	entity.origin = origin
	entity.model = model
	entity.spawn_flags = 265
	entity.spawn()
	SayText2(str(entity.index)).send()
	
	global index
	index = entity.index


@EntityPreHook(EntityCondition.equals_entity_classname('prop_physics_override'), 'use')
def _on_start_touch(stack):
	entity = make_object(Entity, stack[0])
        # Retrieving index from stack[1] causes the crash.
        # I know I am trying to create a Player object, but just retrieving the index_from_pointer causes it too.
	player = make_object(Player, stack[1])

Maybe try making an Entity or BaseEntity object first out of stack[1]. That's what I do when I don't have any clue about which info I would get. If the server doesn't crash, print stack[1]'s classname to figure out exactly what is happening. Maybe the stack[1] is player only at some point, and at some other point it's worldspawn or something. :D

I think it's an InputFunction, so the second argument would be InputData. But you could also simply use the OnEntityOuutput listener.

Which SP version are you running btw.?

@Backraw:
Index from pointer conversions work for simple entities and players.

Yeah it was just a guess. :)

Yes, but it would only work if there are actual output connections on that entity. What if there're none?

[Predz]

I am trying to detect a player pressing +use on a prop which I can then parent to the player, looking like they are carrying it. So I could just check for the closest player. But again that is just working on a "derped" method rather than actually trying to fix my problem. :P

I did look to see if any in game offsets would be available for said function, but have no luck so far.

SP Version: 323

Well, as Ayuto stated, the 2nd argument is InputData. So, you could use make_object to get the object and the use the (I believe) activator attribute to find out which entity caused it.

Sorry took me a while to catch on...

Working code below for reference:

from players.entity import Player
from players.helpers import index_from_userid
from entities.entity import Entity
from entities.datamaps import InputData
from entities.hooks import EntityPreHook
from entities.hooks import EntityCondition
from events import Event
from memory import make_object

model = Model('models/props/cs_militia/toilet.mdl')

global index

@Event('player_say')
def _on_say(event):
	player = Player(index_from_userid(event['userid']))
	origin = player.view_coordinates
	
	entity = Entity.create('prop_physics_override')
	entity.origin = origin
	entity.model = model
	entity.spawn_flags = 265
	entity.spawn()
	SayText2(str(entity.index)).send()
	
	global index
	index = entity.index


@EntityPreHook(EntityCondition.equals_entity_classname('prop_physics_override'), 'use')
def _on_start_touch(stack):
	entity = make_object(Entity, stack[0])
	input = make_object(InputData, stack[1])
	
	player = Player(input.activator)
	SayText2(player.name).send()
