[L4D2] how to filter glass in TR_TraceRayFilterEx? about player visible

here is my code, I want to implement a function to detect if a player is visible to another player.

Code:

bool is_visible_to(int client, int target)

{

    float self_pos[3];

    float target_pos[3];

    float look_at[3];

    float vec_angles[3];

    GetClientEyePosition(client, self_pos);

    GetClientEyePosition(target, target_pos);

    MakeVectorFromPoints(self_pos, target_pos, look_at);

    GetVectorAngles(look_at, vec_angles);

    Handle trace = TR_TraceRayFilterEx(self_pos, vec_angles, MASK_VISIBLE, RayType_Infinite, trace_entity_filter, target);

    bool result = TR_DidHit(trace) && TR_GetEntityIndex(trace) == target;

    delete trace;

    return result;

}



bool trace_entity_filter(int entity, int contentsMask, any data)

{

    if(entity == data)

    {

        return true;

    }

    if(entity > 0 && entity <= MaxClients)

    {

        return false;

    }

    char class_name[PLATFORM_MAX_PATH];

    GetEntityClassname(entity, class_name, sizeof(class_name));

    return strcmp(class_name, "infected") != 0 && strcmp(class_name, "witch") != 0 && strncmp(class_name, "prop_dynamic", 12) != 0 && strncmp(class_name, "func_breakable", 14) != 0;

}

I found that issue, the glass(map c11m1_greenhouse, classname "prop_physics", image attached below) did hit the trace, but there is no survivor glow, so it's "visible" but my function return false. how can I filter something such like this?

Note:
I tried L4D2_IsVisibleToPlayer in left4dhooks, it can't meet my needs cause when someone are not alive and spectating another one, the "eye position" not follow.

You wanna not include CONTENTS_WINDOW in your trace mask,
Never really used MASK_VISIBLE macro, I just build own.

I looked again at my trace filter code, I used this

PHP Code:


		
			
GetEntProp(iEntity, Prop_Data, "m_iEFlags")) & (1<<25)

to filter entity glass like that EFL_DONTBLOCKLOS
