On this page you will find only two Expanded Use Cases. These two represent the two major categories of Use Cases: the creating of buildings and the performing of actions (by humans). All the Expanded Use Cases of those two types have a similar course of events. The Use Cases in which a human is created, are considered to be trivial, so we don't include their Expanded Use Cases.

Expanded Use Cases

Use Case: Perform Action

Section: Main

Use Case	Perform Action
Actors	Player
Purpose	Start the action of a selection of humans on one or more selected squares.
Overview	The Player decides to let one or more humans perform an action. First he selects one or more humans, and then he selects an action. Finally the Player selects one or more squares of explored land. There needs to be enough resources to let this human perform the action. The action will be performed on the spot the Player chooses, otherwise, the system indicates that there is not enough of one or more of the resources, or that the squares of land are not suitable for this action, or that there is already a human standing on the selected square of land. During the action, the amount of certain resources will change gradually: every action consumes some resources; some actions even produce resources and/or change the state of the square of land. The human will perform this action, as long as there are enough resources, and he is not instructed to do something else. When the action is finished on the given square, he will try to find an adjacent field where he can continue his action.
Type	Primary
Cross references	Functions: R1.4, R1.5, R2.1, R2.2, R2.3, R2.4, R3.2 Use Cases: The Player must have completed the Create Human use case.

Typical course of events

Actor Action	System Response
1. This use case begins when the Player decides to <perform an action>.
2. The Player selects one or more humans.	3. Keeps track of the selected humans.
4. The Player indicates a <perform action> option: If "constructing", initiate "Create construction". Otherwise, initiate "Perform normal action".

Remark: In this typical course of events the words embraced by < > can be replaced by a human activity (chopping wood, fishing, ..).

Section: Perform Normal Action

Use Case	Perform Normal Action
Actors	Player
Purpose	Start the normal action of a selection of humans on one or more selected squares.
Overview	The Player decides to let one or more humans perform an action. First he selects an action. Finally the Player selects one or more squares of land. There needs to be enough resources. The action will be performed on the spot the Player chooses, otherwise, the system indicates that there is not enough of one of the resources, or that the square of land is not suitable for this action, or that there is already a human standing on the selected square of land. During the action, the amount of certain resources will change gradually: every action consumes some resources; some actions even produce resources and/or change the state of the square of land. The human will perform this action, as long as there are enough resources, and he is not instructed to do something else. When the action is finished on the given square, he will try to find an adjacent field where he can continue his action.
Type	Primary
Cross references	Functions: R1.4, R1.5, R2.1, R2.2, R2.3, R3.2

Typical course of events

Actor Action	System Response
1. This use case begins when the Player chooses to perform a <normal action>.
2. The player selects one of the normal actions.	3. Awaits the selection of one or more explored squares of land on the board.
4. The Player indicates the square of land.	5. The human starts perfoming the selected <normal action>.
	6. The amount of resources (and sometimes also the transformationstate of the selected squares of land) is changed gradually until the human is instructed to do another action.
	7. When the action is finished on this square of land, the human will search for another square nearby to continue performing the action he was doing. If he doesn't find an appropriate square, he will rest until he can continue.

Remark: In this typical course of events the words embraced by < > can be replaced by a human activity (chopping wood, fishing, ..).

Alternative courses

Section 5: When the indicated square of land is not valid for this selected action, the system indicates an error and the human continues his current activity.
Section 5: When the indicated square of land is already taken by another human, the system indicates an error and the human continues his current activity.
Section 5: When there are not enough resources to perform this action, the human remembers his action, but will start resting (untill the necessary resources are available again, ). When there is a shortage of food, the human will consume his energybuffer. Some actions that can be performed although the human is consuming his energy buffer (like fishing, resting, ...), some others can't (wood chopping, geological investigation, ...). When the energybuffer is empty, the human dies.
Section 5: When there are not enough land resources, the human searches for another square nearby where he can perform the action. If he doesn't find such an appropriate square of land, he will start resting on the indicated square of land.

Section: Create Construction

Use Case	Create Construction
Actors	Player
Purpose	Start the creation of a construction.
Overview	The Player decides to let one or more humans perform a constructing action. First he chooses which construction he wants to create. Then the Player chooses the shape of the construction and selects some squares of explored plain land where he wants this construction to be build. The constructing action will be performed on the spot the Player chooses, otherwise, the system indicates that there is not enough of one or more of the resources, or that the squares of land are not suitable for this action, or that there is already a human or a construction standing on the selected square of land. During the constructing action, the amount of certain resources will change gradually: every constructing action consumes some resources. The human will perform this action, as long as there are enough resources, and he is not instructed to do something else.
Type	Primary
Cross references	Functions: R1.4, R1.5, R2.1, R2.2, R2.3, R3.2

Typical course of events

Actor Action	System Response
1. This use case begins when the Player chooses to perform <constructing>.
2. The Player indicates which building he wants to create.	3. Asks the shape of the construction the Player wants to create. Although there can be more humans selected then the number of squares in the shape of the contruction, the maximum number of humans that that will create the construction is limited to the size of the construction.
4. The Player indicates the shape.	5. Awaits the selection of the number of explored squares of plain land (the construction location) on the board.
6. The Player indicates the construction location.	7. The human starts perfoming the selected <create construction > action.
	8. The amount of resources and also the state of the construction will change gradually until the human is instructed to do another action or until the construction is completed.
	9. When the construction is completed, the human starts resting.
	10. The construction starts working: it will gradually consume and produce some resources.

Alternative courses

Section 7: When the indicated square of land is not valid for this selected action, the system indicates an error and the human continues his current activity.
Section 7: When the indicated square of land is already taken by another human or another construction, the system indicates an error and the human continues his current activity.
Section 7: When there are not enough resources to perform this action, the human remembers his action, but will start resting (untill the necessary resources are available again ). When there is a shortage of food, the human will consume his energybuffer. When the energybuffer is empty, the human dies.
