    'self' mob entity
    'pos' centre position of explosion
-   'radius' radius of explosion (typically set to 3)
-   'damage_radius' radius of damage around explosion
+   'damage_radius' radius of node damage (typically 3)
+   'entity_radius' radius of explosion to players and mobs
    'texture' particle texture during explosion, defaults to "tnt_smoke.png"
 
 This function generates an explosion which removes nodes in a specific radius
