Making an entity explode

[sm69baller]

Hi i'm making a SNPC but on function [B]ENT:Killed()[/B] [B]and if the NPC comes to close[/B] i have to make it explode Does sombody know how I should make my function [B]ENT:Explode()[/B] ??

So this is what i got on [B]function ENT:Killed()[/B]

function ENT:Killed()
if math.random(1,3) == 1 then
	  self:EmitSound( self.die1,460,math.random(80,120))
	elseif math.random(1,3) == 2 then
	  self:EmitSound( self.die2,460,math.random(80,120))
	elseif math.random(1,3) == 3 then
	  self:EmitSound( self.die3,460,math.random(80,120))
	end
	
  self:Explode()
  

end

SO now i need to have an ENT explode.

Thx in advance !
