# Logic
|
||
|
|
## Initial State:
|
||
|
|
* Lifts all at the bottom of the building
|
||
|
|
* People all outside the building
|
||
|
|
* not waiting on an arrow
|
||
|
|
* not in a lift
|
||
|
|
|
||
|
|
## State 1:
|
||
|
|
### *These are performed simulataneously*
|
||
|

|
||
|
|
* Lift Thread
|
||
|
|
1. Lift waits for a short amount of time (to allow people to enter the building)
|
||
|
|
2. If no one is in the lift, it calls `get_into_lift()`
|
||
|
|
3. `get_into_lift()` checks if someone is waiting on the up arrow semaphore
|
||
|
|
4. Two things must then happen:
|
||
|
|
* First, the lift must update the lift that currently is on that floor
|
||
|
|
* Second, the lift must signal to a passenger that it may enter.
