I've been trying to bring back some of movement from 1.6 (sticky ladders, doubleducking, stand-up bhop, etc.) Here is the sticky ladder part from my plugin. There must be another, concrete way to have sticky ladders, but hey, it works!

PHP Code:

#include <sourcemod>
#include <sdktools>
#include <sdkhooks>

#define PLUGIN_VERSION "1.01"

#pragma semicolon 1
#pragma newdecls required

float frametime;

public Plugin myinfo = 
{
    name = "Sticky ladders", 
    author = "juice", 
    description = "Make players stick to ladders without holding any movement key", 
    version = PLUGIN_VERSION, 
    url = "https://github.com/juicejuicejuice"
};

public void OnPluginStart()
{
    frametime = GetTickInterval();
}

public void OnClientPutInServer(int client)
{
    SDKHook(client, SDKHook_PreThink, OnPlayerPreThink_Pre);
}

public void OnClientDisconnect(int client)
{
    SDKUnhook(client, SDKHook_PreThink, OnPlayerPreThink_Pre);
}

public Action OnPlayerPreThink_Pre(int client)
{
    if (!IsPlayerAlive(client))
    {
        return;
    }
    
    if (GetEntityMoveType(client) == MOVETYPE_WALK)
    {
        float velocity[3];
        GetEntPropVector(client, Prop_Data, "m_vecAbsVelocity", velocity);
        
        if (!velocity[0] && !velocity[1] && !velocity[2])
        {
            return;
        }
        
        float origin[3];
        GetClientAbsOrigin(client, origin);
        
        float mins[3], maxs[3];
        GetEntPropVector(client, Prop_Send, "m_vecMins", mins);
        GetEntPropVector(client, Prop_Send, "m_vecMaxs", maxs);
        
        float wishpos[3];
        wishpos[0] = origin[0] + velocity[0] * frametime;
        wishpos[1] = origin[1] + velocity[1] * frametime;
        wishpos[2] = origin[2] + velocity[2] * frametime;
        
        Handle tr = TR_TraceHullFilterEx(origin, wishpos, mins, maxs, MASK_PLAYERSOLID, TraceFilter_IgnoreSelf, client);
        
        if (TR_DidHit(tr))
        {
            float planeNormal[3];
            TR_GetPlaneNormal(tr, planeNormal);
            SetEntityMoveType(client, MOVETYPE_LADDER);
            SetEntPropVector(client, Prop_Send, "m_vecLadderNormal", planeNormal);
        }
        
        CloseHandle(tr);
    }
}

public bool TraceFilter_IgnoreSelf(int ent, int mask, any data)
{
    return (ent != data);
}
