Break barrier ugx_requiem style? in Help Desk

Hi, I've played UGX Requiem and I am trying to add wood barriers only breakable with my custom axe, similar to requiem map. I've made a script but it works with a problem.

Code Snippet

Plaintext

axe_break()
{
	triggers = GetEntArray("trigger_break_axe", "targetname");

	for(i=0; i<triggers.size; i++)
	{
		triggers[i] thread wait_for_break();
	}
}

wait_for_break()
{
	blocker = GetEnt(self.target, "targetname");

	while(1)
	{
		self waittill("trigger", player);

		weapon = player getCurrentWeapon();

		if (weapon == "axe")
		{
			player play_sound_on_entity( "wood_break" );
			blocker delete();
			flag_set(self.script_noteworthy);
			self delete();
		}
		wait 0.3;
	}
}

The script actually works, in radiant I have a trigger_damage for each wooden barrier. But when I hit the trigger with the weapon ("axe") the game freezes for 1 or 2 seconds, and after a delay the blocker is deleted.

What is causing the game to freeze? And why is there a delay for the blocker to be deleted when there is no delay on the script :v

Thanks in advance, sorry for english :p

wait_for_break() { blocker = GetEnt(self.target, "targetname"); while(1) { self waittill("trigger", player); weapon = player getCurrentWeapon(); if (weapon == "axe") { player play_sound_on_entity( "wood_break" ); blocker delete(); flag_set(self.script_noteworthy); self delete(); break; // ADD THIS } wait 0.3; } }
