Cave-in Weird Explosion? (not good)

[Amnesiaplayer]

Ni mean this : player place the explosive.
when dropping rock... the sound is playing and flaming fire is upon the Bucket and then BOOOM
and i understand what you mean... i got this script from frictional games.. but it doesn't work ?! i have a new script like this :

PHP Code: (Select All)

void DaBigBoom(string &in asEntity, string &in asType)
{
    AddTimer("sound", 1, "TimerBigBoomEvent");
    AddTimer("1", 4, "TimerBigBoomEvent");
}

void TimerBigBoomEvent(string &in asTimer)
{
    if(asTimer == "sound"){
        PlaySoundAtEntity("epoxyignite", "12_epoxy_blow", "cave_in_1", 0, false);
        StartScreenShake(0.01, 0, 0, 2.9f);
        return;
    }
    
    SetEntityActive("Bomb", false);
    
    SetPropHealth("BlockingRocks", 0);
    
    StartScreenShake(0.08, 2.5f, 0, 1.0f);
        PlayMusic("12_puzzle_cavein.ogg", false, 1, 0.0f, 10, true);
} 


and my callback func is this :
AddEntityCollideCallback("BamRock", "Bomb", "DaBigBoom", true, 1);
yes my rock name is BamRock and explosive name is Bomb.
the only thing that happen is flaming bucket after dropping a stone and then the bucket go away... nothing happens the cave-in is still there :S
