I've been working on destroyable object for carepack system but seems like doesen't work. When i shoot with gun in object, it won't destroy. What's the problem ?

Code:

new ArmyCrate[MAX_CRATES];

Code:

for(new i=0; i < MAX_CRATES; i++)
	{
	    ArmyCrate[i] = 50; //This should be like object health i want to destroy
		pCarePackage[i][CarePackagePlane] = pCarePackage[i][CarePackageParachute] = -1;
	}

Code:

public OnPlayerWeaponShot(playerid, weaponid, hittype, hitid, Float:fX, Float:fY, Float:fZ)
{
    if(hittype == BULLET_HIT_TYPE_OBJECT)
	{
    	for(new val = 0; val < MAX_CRATES; val++)
		{
			if(crateexists[val])
			{
			    new obb = ArmyCrate[val];
				if(IsValidDynamicObject(obb))
				{
					new Float:oX, Float:oY, Float:oZ;
					GetDynamicObjectPos(obb,oX, oY, oZ);
					if(IsPlayerInRangeOfPoint(playerid, 5, oX, oY, oZ))
					{
					    ArmyCrate[val] -= 1;
					    if(ArmyCrate[val] > 0)
					    {
							DestroyDynamicObject(obb);
							Delete3DTextLabel(armylabel[val]);
							SendClientMessage(playerid, -1, "You got some weapons from pack.");
							new rand = random(4);
							switch(rand)
							{
								case 0: GivePlayerWeapon(playerid, 29, 300);
								case 1: GivePlayerWeapon(playerid, 32, 300);
								case 2: GivePlayerWeapon(playerid, 37, 400);
								case 3: GivePlayerWeapon(playerid, 35, 1);
							}
							crateexists[val] = false;
							KillTimer(CrateDespawnTimer[val]);
							ArmyCrate[val] = -1;
							break;
	 					}
					}
				}
			}
		}
 	}
