This section explain all the functionnalities in the challenge part
## Quiz
A quiz includes 4 basic questions and one custom question.
### Basic Question
All basics Questions are created in the quizEntity.json. We have to add :
- questionLabel => Label of the question
- Answers => An array of three answers (answerLabel, isTrue)
- description => Explain the question
- source => Source of the explanaition
This questions and answers are in random order.
In the question page the user have to select an answer and click validate.
Then, he sees the right answer and a modal with the explanation and the source. After this modal, he goes to the next question.
Depends on the answer, the question result state is set either correct or incorrect.
If it is a right answer, the quiz result is incremented by one.
### Custom Question
At the end of every quiz, we're creating a custom question.
Here are the fields used to create a custom question
| Field | Type | Description |
| ---------- | ------------------ | ---------------------------------------------------------------- |
| type | CustomQuestionType | Type of custom qusetion: DATE or MAXLOAD or AVERAGE. |
| timeStep | TimeStep | Time step of the result value (DAY / WEEK / MONTH / YEAR). For MAXLOAD or AVERAGE type, it represents daily / weekly / monthly / yearly average. |
| interval | TimeStep | Interval in which the data will be searched (DAY / WEEK / MONTH / YEAR) |
| period | CustomPeriod | Case day / month / year:<br/>Use to define a specific period for the interval { day? / month? / year? }. <br/>Case weekday:<br/>Only usable with AVERAGE type and DAY timestep: Allow to specify a weekday on which average is made. If used with another type, period will not be taken into account.<br/>If not assigned the period will be the last interval (example: last week) |
| singleFluid | boolean | Indicate if all connected fluid should be taken into account.<br/>If set to true only the first connected fluid will be taken into account in this order: electricity, gas, water. #unit and #fluid in the question label will be replace by the unit and the name of the fluid |
| result | UserQuizState | Indicate the state of the custom question (UNLOCKED, CORRECT, UNCORRECT) |
Calculation of custom question is done by conbinaison of all parameters:
- Type DATE
- If *period* is empty.
Retrieve the **date** of day/month/year (define by *timeStep*) from the last week, month, year (define by *interval*).
```
example: What day did I consumme the most on the last week ?
type = CustomQuestionType.DATA
timeStep = TimeStep.DAY
interval = TimeStep.WEEK
period = {}
singleFluid = false
```
```
example: What day did I consumme the most #fluid in #unit on the last week ?
type = CustomQuestionType.DATA
timeStep = TimeStep.DAY
interval = TimeStep.WEEK
period = {}
singleFluid = true
```
- If *period* is not empty
Retrieve the **date** of day/month/year (define by *timeStep*) from a week, month, year (define by *interval*) of *period*
```
example: What month did I consumme the most on year 2020 ?
type = CustomQuestionType.DATA
timeStep = TimeStep.MONTH
interval = TimeStep.YEAR
period = { year: 2020 }
singleFluid = false
```
- Type MAXLOAD
- If *period* is empty
Retrieve the **maxload** value of day/month/year (define by *timeStep*) from the last week, month, year (define by *interval*).
```
example: Which is your daily max consumption on the last week ?
type = CustomQuestionType.MAXLOAD
timeStep = TimeStep.DAY
interval = TimeStep.WEEK
period = {}
singleFluid = false
```
- If *period* is not empty
Retrieve the **maxload** value of day/month/year (define by *timeStep*) from a week, month, year (define by *interval*) of *period*
```
example: Which is your daily max consumption on january 2020 ?
type = CustomQuestionType.MAXLOAD
timeStep = TimeStep.DAY
interval = TimeStep.MONTH
period = { month: 1, year: 2020 }
singleFluid = false
```
- Type AVERAGE
- If *period* is empty
Retrieve the **average** of day/month/year (define by *timeStep*) from the last week, month, year (define by *interval*).
```
example: Which is your daily average consumption on last week ?
type = CustomQuestionType.AVERAGE
timeStep = TimeStep.DAY
interval = TimeStep.WEEK
period = {}
singleFluid = false
```
- If *period* is not empty
Retrieve the **average** of day/month/year (define by *timeStep*) from a week, month, year (define by *interval*) of *period*
```
example: Which is your daily average consumption on january 2020 ?
type = CustomQuestionType.AVERAGE
timeStep = TimeStep.DAY
interval = TimeStep.MONTH
period = { month: 1, year: 2020 }
singleFluid = false
```
- If *period* is weekday
Retrieve the **average** of the *weekday* from a week, month, year (define by *interval*).
```
example: Which is your daily average consumption on wednesdays of last month?
type = CustomQuestionType.AVERAGE
timeStep = TimeStep.DAY
interval = TimeStep.MONTH
period = { weekday: 3 }
singleFluid = false
```
Then, two randoms answers are generated after defining the right answer.
A user can stop during a quiz and picks up where he left off. To define where the user left off, we have to check if at least one of the question result status is unlocked.
Once the custom question is answered, the quiz state is set to done. Then, the user sees his result and his earned stars. He can also retry or go back to the challenge page.
## Exploration
Exploration is a feature which in the user got to do an action in order to help him to discover all features of this app.
They are 4 types of action :
- DECLARATIVE : The user has to do something outside of the app => No way for the app to know if the user did it so we trust him.
- ACTION : Action whitin the app. When the user finish he got a notification.
- CONSUMPTION : He got to do something in his consumption view.
- ECOGESTURE : He need to have a look to a specific Ecogesture.
In order to check if an exploration (which is not declarative) is done, a hook called useExploration is used.It is called on component that has to check if an exploration is done.
This hook called exploration service to check exploration by passing two parameter(the current challenge and the user exploration id associated with the exploration id of the current challenge). This check is done only if:
- There is a current challenge
- exploration.id of the current challenge is equal to the user exploration id
- exploration.state is ONGOING
Depends on the type of an exploration, either the exploration remains in progress until it is fully done or it ends.
When the user finish the exploration, he got a success message and five more stars on his challenge progression.
## Duel
### On launch
In order to find a valid reference period we search for a period which is defined by the duel duration.
We check the most recent period first if it's complete and then we go farther and farther in the time if the ones before got missing values.
We also define a threshold for a maximum old period (6 months for the moment determined in the code ==> hardcoding).
If the thresold is reached and no valid period was found, we alert the user that he can't launch the duel and have to wait before he can retry this process.
### On going
Every time the user go into the duel mode, we are checking if the duel is finished.
if we have retrieve all data to calculate the user consumption on the duel duration, the duel is done
!!! info "In order to not block the user is a value is mising, we are also set the duel as done when we reach the startDate + delay in day to retrieve the data (based on the fluid) + 1 day. In this case the user consumption is done on known values."
### On finish
Once the state of the duel is set to DONE, we save the user result and determine if he wins (userComsumption < threshold of the reference period) or if he loses. Then the user sees his earned badge.
## Challenges
We can find the file challengeEntity.json in the /db folder. This file contains an array of challenges, and each of them includes relationships to duels, quiz, missions and actions.
### UserData creation
Once a user launch a challenge in the Ecolyo app, we create a userChallenge and store it in the couchDB under the doctype '**com.grandlyon.ecolyo.userchallenge'.** During this process, the objects related to the challenge (quiz, duel, mission, action) will be be converted to an user version which contains informations about the user progress, the fluids connected and so on. So we have now a userChallenge that contains a userQuiz, a userDuel, etc. instead of relations.
To illustrate this, let's show the conversion of quizEntity to userQuiz :
```jsx
DuelEntity {
id: string
title: string
description: string
duration: Duration
}
```
Becomes :
```jsx
UserQuiz {
id: string
title: string
description: string
duration: Duration
threshold: number
state: UserDuelState
startDate: string | null
fluidTypes: FluidType[]
userConsumption: number
}
```
