When using register_touch, for example

PHP Code:

register_touch("func_wall",  "player", "Touch_Wall"); 


Within Touch_Wall function, set_pev command does not seem to work.
For instance

PHP Code:

public Touch_Wall(id)
{
      set_pev(id, pev_velocity, Float:{0.0,0.0,0.0});
} 


The above code is supposed to stop player's movement but it doesn't.
But if I use

PHP Code:

public Touch_Wall(id)
{
      set_task(0.1, "Task_Wall", id);
}

public Task_Wall(id)
{
      set_pev(id, pev_velocity, Float:{0.0,0.0,0.0});
} 


it works just fine.
Any ideas why?

Thanks in advance.

your "touch_wall" is called from engine:

PHP Code:

void SV_RunCmd(usercmd_t *ucmd, int random_seed)
{
...
...

    if (host_client->edict->v.solid)
    {
        vec3_t vel;
        pmtrace_t *tr;

        SV_LinkEdict(sv_player, true);
        
        //Engine save current player's velocity here
        VectorCopy(sv_player->v.velocity, vel);

        for (i = 0; i < pmove->numtouch; i++)
        {
            tr = &pmove->touchindex[i];
            ent = EDICT_NUM(pmove->physents[tr->hitgroup].info);

            SV_ConvertPMTrace(&trace, tr, ent);

            VectorCopy(tr->deltavelocity, sv_player->v.velocity)
            SV_Impact(ent, sv_player, &trace);
        }

        //and recover velocity here in case someone modify player's velocity
        VectorCopy(vel, sv_player->v.velocity);
    }
...

} 


and

PHP Code:


void SV_Impact(edict_t *e1, edict_t *e2, trace_t *ptrace)
{
...
...
    if (e1->v.solid != SOLID_NOT)
    {
        SV_SetGlobalTrace(ptrace);
        gEntityInterface.pfnTouch(e1, e2);
    }

    if (e2->v.solid != SOLID_NOT)
    {
        SV_SetGlobalTrace(ptrace);
        gEntityInterface.pfnTouch(e2, e1);
    }
...
...
} 


it's obvious that your new velocity change in

PHP Code:

gEntityInterface.pfnTouch(e1, e2); 


is overwritten here

PHP Code:

VectorCopy(vel, sv_player->v.velocity); 


so the change has no effect. and you have no access to the "vec3_t vel" in engine 's stack memory.
you'd better do phys calculation like changing velocity in playermove code (PM_Move), or set a flags then set new velocity in PlayerPostThink

Makes sense, thanks
