A Hooks Library?

[MiBShidobu]

I was wondering if Source.Python will come with a hooking module for scripts. Sorta like how scripts can fire custom events but can instead make custom listeners/hooks that can return information back to the calling script. Sorta of like this:

Syntax: Select all

from Source import Player
from events.decorator import Event
from hooks import CallHook
 
@Event("player_activate")
def OnPlayerActivate(game_event):
    # variable(list/tuple) = CallHook(<hookname>, <input variables>)
    hook_args = CallHook("player_should_get_health", (Player.EdictOfUserid(game_event.GetInt('userid')), ))
    if hook_args:
        # do stuff

And then another script can do this:

Syntax: Select all

from hooks import Hook

# Works same way as Event method from events.decorator module.
@Hook("player_should_get_health")
def OnPlayerShouldGetHealth(player)
    return (true, )

This way scripts can extend their functionality with hooks to change how it was gonna handle stuff.

This seems very silly to me. What exactly would be the point of including this? Maybe your example is confusing me, but it seems pointless.

Also, 2 things with your first bit of code. First, in future versions (committed changes last night), it will be:[python]from events import Event[/python]
Second, you cannot declare custom names for events like that, nor will that be added in the future.

I don't see the point of this either.

Or do you mean something like pre-hooking events and preventing them from fireing and/or chageing the attributes before they actually fire?

Even though this is bumping a few month old thread but I have the same question. Is pre-hooking/detouring available to do at the moment and if so could someone explain how to do it.

[satoon101]

Not yet. I'm not sure, at this point, "when" it will get implemented, but it definitely will be at some point. I really don't think that is what MiBShidobu was referencing, though.

Yeah I understand what you mean. I just didn't want to recreate a topic when there's one with the same topic.
