There is a better way than a Tick listener. You save the current timestamp of the first jump and compare it when the player tries to jump again. If there is enough time elapsed between both jumps (or attemps to), you allow the jump otherwise you block it.

Sounds good, gonna try it with 2.0 seconds

What if somebody's falling for a while and double jumps right before they hit the ground? It might be longer than just X seconds.

If I recall correctly from my SourcePawn days, there's an event for when a player's ground ent changes (e.g. they hit the ground), you could just have a boolean set when a player jumps and unset when their ground ent changes to 0 (or any value other than -1)

that would be awesome if that exists
that would probably be the best solution for this

Something like this?

Syntax: Select all

import memory

from memory import Convention
from memory import DataType

from memory.hooks import PreHook

from players.entity import Player

server = memory.find_binary('server')

CreateInterface = server['CreateInterface'].make_function(
    Convention.CDECL,
    [DataType.STRING, DataType.POINTER],
    DataType.POINTER
)

g_pGameMovement = CreateInterface('GameMovement001', None)

# CCSGameMovement::OnLand(float)
OnLand = g_pGameMovement.make_virtual_function(
    26,
    Convention.THISCALL,
    [DataType.POINTER, DataType.FLOAT],
    DataType.VOID
)

@PreHook(OnLand)
def pre_on_land(args):
    player = memory.make_object(Player, args[0].get_pointer(3744))
    print('%s landed!'% player.name, args[1])

Works with CS:S (Windows).

Thanks, perfect replace for the ticklistener onGround check

Just tested this abit and found out that this is not the best way or pretty useless.

so lets say the pre_on_land fires this function

Syntax: Select all

def onGround(self):
        self.stagejumps = 0
        self.totaljumps = 0

And we have this for jumps (fired by player_jump event)

Syntax: Select all

def jumpEvent(self):
            self.jumps+= 1

But in the end it always show

self.jumps = 1

Mhm

Sorry to dig up an old topic, but could you please explain how you found 3744 as the offset for the player pointer?

CCSGameMovement::OnLand() is quite simple. All it does is calling CCSPlayer::OnLand(). To do that it needs the player instance (CCSPlayer). It's retrieved by accessing this+0x0EA0 (3744).
