# --description--
|
||||
|
||||
To keep track of the player's experience points, we've declared a variable called `xp` and assigned it the starting value of 0.
|
||||
|
||||
Create another variable to keep track of health and start it at 100.

||||

assert(health === 100);

Create a variable called `currentWeapon` and set it to 0. When a name has two words, the convention is to use so-called "lowerCamelCase". The first word is all lowercase, and then the first letter of every preceding word is uppercased.

|

We've been declaring variables with the `var` keyword. However, in modern JavaScript, it's better to use `let` instead of `var` because it fixes a number of unusual behaviors with `var` that make it difficult to reason about.
|
||||
|
||||
Change every `var` to `let`.

||||

Now you will declare a variable without initializing it.
|
||||
|
||||
Using the `let` keyword, declare a variable called `fighting` but don't set it equal to anything. Just end the line with a semicolon right after the variable name.

Since the inventory can store multiple items, change the value of `inventory` to an array with the items stick, dagger, and sword.
|
||||
|
||||
Here is an example of a variable sandwich that equals a three-item array:
|
||||
|
||||
```js
|
||||
let sandwich = ["peanut butter", "jelly", "bread"];
|
||||
```

In order to update HTML elements on the page, you need to get references to them in your JavaScript code. The code `let el = document.querySelector("#el");` gets a reference to an HTML element with an `id` of `el` and assigns it to the variable `el`.
|
||||
|
||||
Get a reference to the HTML element with the `id` of `button1` and assign it to a variable with the name `button1`.

You can also declare variables with the `const` key word. Since `button1` is a constant that will never change, switch the `let` keyword that declares the variable to `const`.

Here are the ids of the other HTML elements that we want a reference to in the JavaScript code: `button2`, `button3`, `text`, `xpText`, `healthText`, `goldText`, `monsterStats`, `monsterNameText`, `monsterHealthText`.
|
||||
|
||||
Just like you did with `storeButton`, create variables and set them equal to the element references.

Designate what the first button in the HTML does by setting the `onclick` property of `button1` to the function name `goStore`. You will create the `goStore` function later. For example, in `button.onclick = openProgram;`, the `onclick` property of `button` is set to `openProgram`.

```js

For now, make the `goStore` function output the message "Going to store." to the web console. For example, here is a function that outputs the message "Hello World" to the web console (Note that code inside a function should be indented):

```js

function functionName() {

console.log("Hello World");

When a player clicks the 'Go to store' button, the buttons and text in the game should change. Remove the code inside the `goStore` function. Add a new line of code inside the function that updates the text of `button1` so that it says "Buy 10 health (10 gold)".
|
||||
|
||||
For example, this code updates the text of `button` to say "Click Me": `button.innerText = "Click Me";`.

Now that the text on the buttons have changed, the `onclick` properties on the buttons should change. Inside the goStore function, update the `onclick` property of all three buttons. The new functions should be `buyHealth`, `buyWeapon`, and `goTown`. If you have trouble, look at how the buttons were initialized.

Add double quote marks around the word "Store" in the line "You see a sign that says Store." Before each quotation mark add a `\` to signal that the following quote is not the end of the string, but should instead appear inside the string. This is called escaping.

# --description--
|
||||
|
||||
There is repetition in the `goTown` and `goStore` functions. When you have repetition in code, it is a sign that you need a new function.
|
||||
|
||||
Above the `goTown` function, create an empty function called `update`. This time the function should take a parameter named `location` so data can be passed into the function when it is called.
|
||||
|
||||
Here is an example of a function named `testFun` that accepts a parameter named `param`:
|
||||
|
||||
```js
|
||||
function testFun(param) {
|
||||
console.log(param);
|
||||
}
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|
||||
See description above for instructions.
|
||||
|
||||
```js
|
||||
assert(update.toString().match(/function update\(\s*location\)\s*\{\s*\}/));
|
||||
```

Arrays can store any data type, including objects. Objects are similar to arrays, except that instead of using indexes to access and modify their data, you access the data in objects through what are called properties.
|
||||
|
||||
Inside the `locations` array add an empty object using curly braces.
|
||||
|
||||
Here is an example of an array named `arr` with an empty object inside: `const arr = [{}];`
|
||||
|
||||
# --hints--
|
||||
|
||||
See description above for instructions.
|
||||
|
||||
```js
|
||||
assert.deepStrictEqual(JSON.stringify(locations), `[{}]`);
|
||||

Inside the object you just added, create a property called `name` with the value of "town square".
|
||||
|
||||
For example, here is an example of an array with an object inside that has a property called `name` with a value of "Quincy Larson" (new lines are used only for the purpose of making the code more readable):
|
||||
|
||||
```js
|
||||
const arr = [
|
||||
{
|
||||
name: "Quincy Larson"
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|

|
||||
|
||||
```js
|

assert(locations[0].name === 'town square');

After the `name` property put a comma. On the next line add a property named `"button text"` that has a value of an empty array. Since the property name has more than one word, there must be quotes around it.
|
||||
|
||||
Here is an example:
|
||||
|
||||
```js
|
||||
const arr = [
|
||||
{
|
||||
name: "Quincy Larson",
|
||||
"favorite colors": []
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|
||||
See description above for instructions.
|
||||
|
||||
```js
|
||||
assert.deepStrictEqual(locations[0]['button text'], []);
|

Inside the `"button text"` array, add three string elements. Use the three stings assigned to the buttons inside the `goTown` function.
|
||||
|
||||
Here is an example array with three strings: `const arr = ["one", "two", "three"];`.

The `locations` array currently has one element which is an object. Within the array, and after the object's final curly brace, add a comma. On the next line within the array, add another object with all the same properties as the first object. Keep the property names the same on the second object, but change all the property values to the information from the `goStore` function. Also, set the `name` property to `store`.

|

Instead of assigning the `innerText` and `onClick` properties to specific strings and functions like it does now, the `update` function will use data from the `location` that is passed into it. First, data needs to be passed into the `update` function. Inside the `goTown` function, call the `update` function.
|
||||
|
||||
Here is how you would call a function named `exampleFunction`: `exampleFunction();`
|
||||

||||

|

assert(goTown.toString().match(/update\(\)/));

Now change the code you just wrote to call the `update` function so the `locations` array is passed in as an argument.

Here is how you would call a function named `exampleFunction` with an argument called `arg`: `exampleFunction(arg);`

The `locations` array contains two locations: the town square and store. Currently the entire array with both locations is being passed in to the update function. Pass in only the first element of the locations array by adding `[0]` at the end of the name of the array. For example, `exampleFunction(arg[0]);`

# --description--
|

|
||||
Now that the `goTown` function calls the `update` function with the first element of the `locations` array, it is time to use that location information to update the `innerText` and `onclick` properties.
|
||||
|
||||
Inside the `update` function, change `button1.innerText` to equal `location["button text"]`. That line gets the `"button text"` property of the `location` that was passed into the `update` function\`.

Finally, update `text.innerText` to equal the `text` from the location object.
|
||||

|

Now that the store and cave locations are complete, we'll code the actions at those locations. Inside the `buyHealth` function, set `gold` to equal `gold` minus 10.
|
||||
|
||||
For example here is how you would set set `num` to equal 5 less than `num`: `num = num - 5;`.
|
||||

buyHealth(), assert(gold === 40);

|

There is a shorthand way to add or subtract from a variable called compound assignment. The long way to add to a variable is `num = num + 5`. The shorthand way is `num += 5`. It works the same way with subtraction.
|
||||
|
||||
Update both lines inside the `buyHealth` function to use compound assignment.

Now that the gold and health variables have been updated, we need to update the values displayed on the screen. Inside the `buyHealth` function, add the line `goldText.innerText = gold;`. Then use the same pattern to update `healthText`.

What if the player doesn't have enough gold to buy health? Put all the code in the `buyHealth` function inside an `if` statement. Here is an example of an `if` statement inside a function:
|
||||
|
||||
```js
|
||||
function checkMoney() {
|
||||
if (condition) {
|
||||
console.log("You have money!");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Note: For now you should use the word "condition" inside the `if` statement but we'll be changing that next.
|
||||

The word "condition" inside the if statement is just a placeholder. Change the condition to check if the amount of gold the player has is greater than or equal to 10.
|
||||
|
||||
Here is an `if` statement that checks if `num` is greater than or equal to 5:
|
||||
|
||||
```js
|
||||
if (num >= 5) {
|
||||
console.log("Num is greater than or equal to five!");
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
```js
|
||||
assert(buyHealth.toString().match(/if\s*\(\s*gold\s*\>\=\s*10\s*\)/));
|

Now when a player tries to buy health it will only work if they have enough money. If the player does not have enough money, nothing will happen. Add an `else` statement where you can put code to run if a player dees not have enough money.
|
||||
|
||||
Here is an example of an empty `else` statement:
|
||||
|
||||
```js
|
||||
if (num >= 5) {
|
||||
console.log("Num is greater than or equal to five!");
|
||||
} else {
|
||||
}
|
||||
```
|
||||
|
||||
# --hints--

|

|

```js

Just like in the `locations` array, all the elements in `weapons` will be objects. Add four objects to the `weapons` array, each with two properties: `name` and `power`. The first should be the `name` "stick" with `power` set to 5. Then, "dagger" with set `power` to 30. Next, "claw hammer" with a `power` of 50. Finally, "sword" with a `power` of 100.

The value of `currentWeapon` corresponds to an index in the `weapons` array. The player starts with a stick since `currentWeapon` starts at 0 and `weapons[0]` is the "stick" weapon. In the `buyWeapon` function, add one to `currentWeapon` since the user is buying the next weapon in the `weapons` array.

You can easily increment or add one to a variable with the `++` operator. All three of these statements add one to a number:
|
||||
|
||||
```js
|
||||
num = num + 1;
|
||||
num += 1;
|
||||
num++;
|
||||
```
|
||||
|
||||
Change the line `currentWeapon += 1;` to use the `++` operator.
|
||||
|
||||
# --hints--

||||
|
||||
See description above for instructions.
|
||||
|
||||
```js
|
||||
assert(buyWeapon.toString().match(/currentWeapon\s*\+\+\;?/));

# --description--
|

|

You can insert variables into a string with the concatenation (`+`) operator. Update the "You now have a new weapon." string so it says "You now have a " and then lists the name of the new weapon. Make sure to add a period at the end of the sentence.
|
||||
|
||||
Here is an example that creates the string "Hello, our name is freeCodeCamp.":
|
||||
|
||||
```js
|
||||
let ourName = "freeCodeCamp";
|
||||
let ourStr = "Hello, our name is " + ourName + ".";
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|
||||
See description above for instructions.
|
||||
|
||||
```js
|
||||
assert(
|
||||
buyWeapon
|
||||
.toString()
|
||||
.match(/[\'\"\`]You now have a [\'\"\`]\s*\+\s*newWeapon\;?/)
|
||||
);

# --description--
|
||||
|
||||
Way back at the beginning you created the `inventory` array. Push the `newWeapon` onto the end of the `inventory` array. Here is an example of pushing onto an array:
|
||||
|
||||
```js
|
||||
let arr = ["first"];
|
||||
let next = "second";
|
||||
arr.push(next);
|
||||
// arr now equals ["first", "second"]
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|
||||
See description above for instructions.
|
||||
|
||||
```js
|
||||
buyWeapon(), assert.deepStrictEqual(inventory, ['stick', 'dagger']);
|
||||
```

||||

# --description--
|
||||
|
||||
At some point in the future, you may want to add more weapons. Instead of checking if `currentWeapon` is less than three, check if `currentWeapon` is less than the length of the `weapons` array. For example, here is how you would get the length of an array called `arr`: `arr.length`.
|
||||
|
||||
# --hints--
|
||||
|
||||
See description above for instructions.
|
||||
|
||||
```js
|
||||
assert(
|
||||
buyWeapon
|
||||
.toString()
|
||||
.match(
|
||||
/if\s*\(\s*currentWeapon\s*\<\s*weapons\.length\s*\)\s*\{\s*if\s*\(\s*gold\s*\>\=\s*30\s*\)\s*\{/
|
||||
)
|
||||
);

We have to fix an error. The `currentWeapon` variable is the array index. Array indexing starts at zero. The index of the last element in an array is one less than the length of the array. In the `if` condition you are working on, change `weapons.length` to `weapons.length - 1`.

Once a player has the most powerful weapon, we'll give them the ability to sell their older weapons back. In the else statement, set `button2.innerText` to equal "Sell weapon for 15 gold". Also, set `button2.onclick` to the function name `sellWeapon`.

Use the `let` keyword to create a variable named `currentWeapon`. Don't set it equal to anything yet. Notice that we already have a `currentWeapon` variable from earlier. Since the `let` keyword is used instead of `var`, this new version of `currentWeapon` is scoped only to this `if` statement. At the close of the `if` statement, the old version of `currentWeapon` will be used again.

Use the `shift()` method on the `inventory` array to remove the first element and return that removed element. Set `currentWeapon` to equal returned element.
|
||||
|
||||
Here is an example:
|
||||
|
||||
```js
|
||||
let arr = ["one", "two", "three"];
|
||||
let firstElement = arr.shift();
|
||||
// arr now equals ["two", "three"] and firstElement now equals "one"
|
||||
```
|
||||
|

|

|

Now we'll start working on fighting monsters. Organize your code by moving the `fightDragon` function to the bottom of the code near the other fight functions.
|
||||
|
||||
Below where the `weapons` array is defined, define a `monsters` array. Set the contents of the `monsters` array to: `{ name: "slime", level: 2, health: 15 }, {name: "fanged beast", level: 8, health: 60 }, { name: "dragon", level: 20, health: 300 }`. Space out the code similar to the `weapons` array so that it is easier to read.
|
||||
|
||||
# --hints--
|
||||
|
||||
See description above for instructions.
|
||||
|
||||
```js
|
||||
assert.deepStrictEqual(monsters, [
|
||||
{ name: 'slime', level: 2, health: 15 },
|
||||
{ name: 'fanged beast', level: 8, health: 60 },
|
||||
{ name: 'dragon', level: 20, health: 300 }

# --description--
|
||||
|
||||
Fighting each type of monster will be very similar so all three fighting functions will call a function named `goFight`. At the end of the code, add an empty function named `goFight`.
|
||||
|
||||
# --hints--
|
||||
|
||||
See description above for instructions.
|
||||
|
||||
```js
|

assert(typeof goFight === 'function');

Inside the `fightSlime` function, set `fighting` to equal 0 (which is the index of the slime in the `monsters` array). On the next line, call the `goFight` function.
|
||||
|
||||
As a reminder, here is how you would call a function named `myFunc`: `myFunc();`.
|
||||
|
||||

assert(fightSlime.toString().match(/fighting\s*\=\s*0\;?\s*goFight\(\s*\)\;?/));

|

|
||||
We'll build out the `attack` function now. For the first line in the function, update the text message to say "The \[monster name] attacks." but replace "\[monster name]" with the actual name of the monster. Remember, you can get the monster name with `monsters[fighting].name`.
|
||||
|
||||
# --hints--
|

See description above for instructions.

fightDragon(), attack(), assert(text.innerText === 'The dragon attacks.');

# --description--
|

|
||||
At the end of that line, add a random number between one and the value of `xp`. Here is the formula to get a random number between 1 and 5: `Math.floor(Math.random() * 5) + 1`.
|
||||
|
||||
`Math.random()` returns a decimal or floating point number between 0 and 1, and `Math.floor()` rounds a given number down to the nearest integer.
|
||||
|
||||

||||
|
||||
See description above for instructions.
|

|

|

(xp = 1),
|
||||
fightDragon(),
|
||||
(monsterHealth = 20),
|
||||
attack(),
|
||||
assert(monsterHealth === 14);
