Hello

Is it possible to trace grenade attacks on a brush entity? Ham_TraceAttack seems to only work for bullets.

/**
     * Description:     Usually called whenever an entity gets attacked by a hitscan (such as a gun) weapon.
     *                  Use the get/set tr2 natives in fakemeta to handle the traceresult data.
     *                  Do not use a handle of 0 as a traceresult in execution, use create_tr2() from Fakemeta
     *                  to pass a custom handle instead.  (Don't forget to free the handle when you're done.)
     * Forward params:  function(this, idattacker, Float:damage, Float:direction[3], traceresult, damagebits)
     * Return type:     None.
     * Execute params:  ExecuteHam(Ham_TraceAttack, this, idattacker, Float:damage, Float:direction[3], tracehandle, damagebits);
     */
    Ham_TraceAttack

I tried Ham_TakeDamage but that doesn't seem to work on brush entities.

Perhaps there's a way to detect grenade blasts within a radius around the brush entity?

Any help is greatly appreciated!

Perhaps there's a way to detect grenade blasts within a radius around the brush entity?

1. Hook takedamage on func_breakable?
2. On explode search ent in radius?

Hook grenade think then get dmgtime, when 1.0s before explode, do check brush entity

PHP Code:

RegisterHam(Ham_Think, "grenade", "fw_ThinkGrenade")

...

public fw_ThinkGrenade(Ent)
{
    if(!pev_valid(Ent)) return HAM_IGNORED

    static Float:dmgtime
    pev(Ent, pev_dmgtime, dmgtime)
    
    if(dmgtime - 1.0 <= get_gametime())
    {
        //Check here
    }
}

Thanks, that works perfect!

Any idea how to keep it from triggering multiple times for each grenade?

What do you mean?

It's a think event, it's going to be called again and again and again until this entity is removed. You can disable the forward or use some boolean to decide when you want to execute the code.

Like Hamlet said, you can disable forward but I suggest you not doing it if you don't know what are you doing.

Other way is the give a boolean but you need to make the g_Checked back to false somewhere to make the grenade check brush entity again

PHP Code:

new bool:g_Checked 

RegisterHam(Ham_Think, "grenade", "fw_ThinkGrenade")

...

public fw_ThinkGrenade(Ent)
{
    if(!pev_valid(Ent)) return HAM_IGNORED

    static Float:dmgtime
    pev(Ent, pev_dmgtime, dmgtime)
    
    if(dmgtime - 1.0 <= get_gametime())
    {
        if(!g_Checked)
        {
                //Check here
                g_Checked = true
        }
    }
}

Thanks guys, the bool global works perfectly. I set it back to false with a set_task.
