The different lock types are: bolt, catch, comb, cmplx, hid, magic, vary, tumb, tumb2, and l_pin. How To Make An Exit Locked: add_exit("parlor","/w/dyno/parlor.c","door"); door_lock("parlor","l_pin",65); This sets up an exit from a room to Dyno's Parlor with a door type. Then door_lock(exitname, locktype, difficulty); sets the exit up as a locked door which will need a lockpick of the 'l_pin' type in order to pick the lock. The '65' is the difficulty of picking the lock successfully. The range for difficulty is from '1' to '100', so pick a number based on the value of the reward behind the door to be fair. Any other questions please mail me. =) Dyno NOTE: Thanes please check before you put picks into play. No need to flood the Realms with 3 types of 'tumb' lockpicks etc. Thanks! Dyno
