Hi uhm I used the cheat commands to check plugin, and testing in all gamemod l4d, l4d2, try to compile with
#define debug 1 You should see these messages 1.) entity created <weapon_fireworkcrate> 2.) entity re-created %f %f %f . physics_timer value Max 2.0 sec, Min 0.01 sec.
If you do not see debug msg then it is not "weapon_fireworkcrate" try to modify the code to get entity's name
PHP Code:
public OnEntityCreated(entity, const String:classname[])
{
PrintToChatAll("entity created <%s>", classname);
.....
