Which is the best way to detect if a player is inside a duct (ventilations)?

Once he is inside there's no need to duck so checking player's buttons in inefficient. I was thinking in force player to stand up and check if he could/couldn't, but I'm not sure how to proceed :/

It's for hns to avoid planting lasermines inside ducts ._.

Any help will be appreciated ^_^

By hooking Ham_Duck. (Not sure if this is it's right name. AFAIK this ham is called in the time, while the user is ducking. So you can set protection from these mines in the function of this ham.

Its Ham_Player_Duck but i don't agree with you...
It will detect duck when the player presses duck key and not detect when hes in vent ( duck without pressing the key)

So i would suggest to try getting flags for ducking

Youfunction() if(pev(id, pev_flags) & FL_DUCKIN) // hes ducking

I'm sure it detects player size and not the key so it will work inside vents

Yes,then just check if he is not pressing a key to duck. This should be enough.

Players will then hold duck while planting .... well

You can quite easily check if a player is in a spot where they can not stand up using a EngFunc_TraceHull call. Simply get the origin and add some amount to the z axis (going upwards) and use that as the trace target. If TR_AllSolid is false and TR_flFraction is smaller than 1.0 the player is in a space where they can not stand up. You maybe have to play around a little with how far you need to move up to accurately detect this.

A simple trace_hull() call should suffice.

These are my 2 options .-.

PHP Code:

stock bool:player_in_duct(id)
{
    new Float:origin[3]
    pev(id, pev_origin, origin)
    origin[2] += 10.0

    engfunc(EngFunc_TraceHull, origin, origin, IGNORE_MONSTERS, pev(id, pev_flags) & FL_DUCKING ? HULL_HEAD : HULL_HUMAN, id, 0 )

    new Float:fFraction
    get_tr2(0, TR_flFraction, fFraction)

    if (!get_tr2(0, TR_AllSolid) && fFraction < 1.0)
        return true

    return false
} 


PHP Code:

stock bool:player_in_duct2(id)
{
        const IN_SOLID_AREA    = (1<<TR_StartSolid)
    new Float:origin[3]
    pev(id, pev_origin, origin)
    origin[2] += 10.0

    if(!(trace_hull(origin, pev(id, pev_flags) & FL_DUCKING ? HULL_HEAD : HULL_HUMAN, id) & IN_SOLID_AREA)) 
        return true

    return false
} 


I'm not sure of trace_hull, I've never used it. I stole some Connor's code

Will be testing later

Bumping ^ Here are the results









TR_AllSolid turns to true inside ventilations & turns false outside.
TR_flFraction always in 1.0 no matter where I am.

In other words, I wasn't able to accurate detect if a player is inside ducts :/

This is my current stock

PHP Code:

stock bool:player_in_duct(id, &solid, &Float:fraction)
{
    static tr
    static Float:origin[3]
    pev(id, pev_origin, origin)
    origin[2] += get_pcvar_float(cvar)
    engfunc(EngFunc_TraceHull, origin, origin, 0, HULL_HEAD, id, tr)
    solid = get_tr2(tr, TR_AllSolid)
    get_tr2(tr, TR_flFraction, fraction)
    if(!solid && fraction < 1.0)
        return true
    
    return false
} 


I tested many distances with the cvar.. With 25-30 I got TR_AllSolid to change
Any help? :c

It's obvious.

PHP Code:

engfunc(EngFunc_TraceHull, origin, origin, 0, HULL_HEAD, id, tr) 


You're starting the trace from "origin" to "origin", distance = 0 units, fraction would be always 1.0 lol
