| 2 | SYNOPSIS |
| 3 | int transfer(object item, object dest) |
| 4 | |
| 5 | DESCRIPTION |
| 6 | This efun is for backward compatibility only. It is only |
| 7 | available in compat mode. |
| 8 | |
| 9 | Move the object "item" to the object "dest". All kinds of |
| 10 | tests are done, and a number is returned specifying the |
| 11 | result: |
| 12 | |
| 13 | 0: Success. |
| 14 | 1: To heavy for destination. |
| 15 | 2: Can't be dropped. |
| 16 | 3: Can't take it out of it's container. |
| 17 | 4: The object can't be inserted into bags etc. |
| 18 | 5: The destination doesn't allow insertions of objects. |
| 19 | 6: The object can't be picked up. |
| 20 | |
| 21 | If an object is transfered to a newly created object, make |
| 22 | sure that the new object first is transfered to it's |
| 23 | destination. |
| 24 | |
| 25 | The efun calls add_weight(), drop(), get(), prevent_insert(), |
| 26 | add_weight(), and can_put_and_get() where needed. |
| 27 | |
| 28 | REPLACEMENT |
| 29 | This efun can easily be replaced with a simul_efun: |
