[function isweapon]
if (type==t_weapon_sword)
elseif (type==t_weapon_fence)
elseif (type==t_weapon_mace_smith)
elseif (type==t_weapon_mace_crook)
elseif (type==t_weapon_mace_staff)
elseif (type==t_weapon_bow_run)
elseif (type==t_weapon_bow)
elseif (type==t_weapon_xbow)
else
return 0
endif
return <uid>

This function is bad anyway.
All weapon got damange values U have just to check the damage value, if exist its a weapon.

Anyway how darksun said. There is already the same function with same name on sphere.
