**Difficulty:** Intermediate

Create Tilemap Arrays, more power-ups, and a secret level!

This guide continues on from our previous guide, [2D Sidescrolling Platformer with MakeCode Arcade](https://www.littlebird.com.au/a/how-to/189/2d-sidescrolling-platformer-with-makecode-arcade). 

In this guide, we'll show you how to create multiple levels, tile maps, backgrounds, more items as well as a secret level. 

Complete this guide to take your 2D sidescrolling platformer to the next level, literally!
This guide continues on from our previous guide, [2D Sidescrolling Platformer with MakeCode Arcade](https://www.littlebird.com.au/a/how-to/189/2d-sidescrolling-platformer-with-makecode-arcade). We'll show you how to create multiple levels, more items as well as a secret level.

## Steps

### Step 1 — Overview

This guide continues on from our previous guide, [2D Sidescrolling Platformer with MakeCode Arcade](https://www.littlebird.com.au/a/how-to/189/2d-sidescrolling-platformer-with-makecode-arcade). We'll show you how to create multiple levels, more items as well as a secret level.

### Step 2 — Create Levels

From the Scene tab, get out a**set background image to ...**block, place it right after s**et backgroundMaps to array of ... **

Then get out a**list get value at ...** block. Change this to read **backgroundMaps get value at num** block. 
We've also placed a **set character position to x 25 y 88**block into the **createLevel**function, this will reset the player's position. 
The block from on start have been repeated here:**set tile ... to ... with wall ON**blocks. 
Finally, we'll still need to call the **generateCoins**function, **generateItems** function, and **generateEnemies** function to re-spawn these sprites every time a new level is created.
As we've done before, we'll create a function again. This time, it will hold all relevant code that will create a new level in our 2D sidescrolling platformer game in MakeCode Arcade. Make a new function and name it **createLevel**. 
Take note that the function type used here accepts an integer number argument, **num.**This num will be used to choose from different level maps and backgrounds.
So far, we've used arrays for multiple enemy sprites as in our version of Space Invaders. This time, we'll use an array to hold the tile maps for all the four levels of our game. 

Create an array and name it **levelTileMaps**, then duplicate the first level's tile map (from on start block) and place it in the array. That will be the first element of our array, an index 0. 
Duplicate the tile map three times, then edit them in the sprite editor to change the positions of the tiles. These will be the next three elements of our levelTileMaps array. 
Next, we'll create another array called **backgroundMaps**. As its name suggests, this will hold all the different backgrounds of the levels.
In this guide, we've imported backgrounds created in an external software such as Aseprite. If you haven't done so yet, check out our [previous guide](https://www.littlebird.com.au/a/how-to/188/create-tile-maps-for-makecode-arcade) on how to import your own.

### Step 3 — Create Secret Level

Apart from the four levels, there will be another secret level! Create a new function for this and name is **createSecretLevel**. Change its background image and tile placement however you like.
In this guide, we've also customised the tile colours for the secret level. Feel free to change it however you would like to.
Reset the player's position with a **set character position x 25 y 20** block.
Create two new functions now, name them **clearItems** and **generateSecretItems**. Later, we'll add blocks to these two functions. For now, just make a call to both functions. 
Then, drag and drop a **start countdown ... (s)** block into the function. Set this to ten seconds.

### Step 4 — On countdown end

Once the countdown to ten seconds ends, the player will be transported back to an ordinary level. So get out a **on countdown end ...**block.
Then make a call to **createLevel**function.

### Step 5 — Update on sprite of kind Player overlaps otherSprite of kind PowerUp

With more levels, this also means that there will be more than one powerUp that the player may pick up. Change the conditional statement to read **if poweredUp greater than or equal to 1 then.**

Create another conditional statement, this time it should check**if poweredUp = 2 then**.
This is an arbitrary condition that we will use to trigger the secret level map. 
After the **destroy powerup**,**change poweredUp by 1**, and**play sound magic wand** blocks, call the **createSecretLevel** function**.**

### Step 6 — Clear Items

Likewise, add a for element poisonousMushroom of array of sprites of kind Enemy block into the function. This block can be found in the **generateEnemies** function.
Add a **destroy poisonousMushroom** block into this for loop.
Previously, we've created a clearItems function but haven't yet added any code to it. So add three destroy ... blocks into it. Set it so that the heart, flag, and powerup sprites will be destroyed with this function call. 
Add a **for element coin of array of sprites of kind Coin**block into the function. Note: This same block has been used in our **generateCoins** function, so feel free to duplicate it from there.
Add a**destroy coin** block into this for loop, this will make it so that every coin sprite in the array will be destroyed.
Back in the createLevel function, add a function call to **clearItems** right before **call generateCoins**.

### Step 7 — Generate Secret Items

The next function we'll need to add code to is the **generateSecretItems** function we had created in a previous step. This function will be used to generate items exclusive to the secret level map. As you might notice, this function is quite similar to our generateItems function.
Create new sprite art for the three items.
Set their position as such so that they appear one after another.

### Step 8 — When Player overlaps Golden Heart Sprite

As we've done in our previous guide, we will add [Overlap Events](https://arcade.makecode.com/courses/csintro3/events/overlap). This can be used to determine what happens when certain sprites overlap other sprites in the game. Here's what this chunk of code does:
The on sprite of kind Player overlaps otherSprite of kind superLife block will increase the player life by 10. 
Then the sprite is destroyed with a**destroy goldHeart**block

A sound effect is played with the **play sound power up** block

### Step 9 — When Player overlaps Immunity Potion Sprite

Next,  here's what this chunk of code does:
The on sprite of kind Player overlaps otherSprite of kind immunity block will check to see if the player sprite has overlapped with the immunityPotion sprite.
The immunityPotion sprite is destroyed with a **destroy immunityPotion**block.
Create a new variable, **immuneAbility** and set to 1. This will be used to make the player immune to enemies later on in the code.
Finally, play a sound effect with**play sound power up**.

### Step 10 — When Player overlaps Gem Sprite

Now to program what happens when the player sprite touches the third special item, the gem sprite, use a **on sprite of kind Player overlaps otherSprite of kind gem** block. What this chunk of code does:
Changes the player score by 25 with a **change score by 25**block.
Destroys the gem sprite with a **destroy gem** block.
Plays a sound effect with a **play sound power up** block.

### Step 11 — Update on sprite of kind Player overlaps otherSprite of kind Enemy

As we've added the immuneAbility, we still need to update the chunk of code that determines what happens when the player sprite overlaps with an enemy sprite! Add the following blocks to it, so that if immuneAbility = 1 and character overlaps with poisonousMushroom then three things will happen:

change life by 0
destroy poisonousMushroom sprite
play sound effect ba ding

If the immuneAbility is not equals to 1, then that means the immunity potion has not been picked up, so the player is not yet immune to enemies. 

### Step 12 — Update Win Condition

Finally, we've yet to update the win condition, so go back over to the**on game update every 500 ms**block. Now when the character sprite overlaps the flag sprite, change level by 1. 
Within that conditional statement, add another conditional statement: **if level > 3 then game over WIN**.
If not, make a function call to createLevel.

You're all done! You can play the complete game, [here](https://arcade.makecode.com/46937-08050-28274-72854). 
How can you modify this game to make it more fun? Some suggestions:

- Tinker with positioning of the randomly generated enemies and coins, so that they always appear above a tile.
- Add different enemy sprites with different penalties
- Add a shop-based system in the secret level, so that you can trade coins for more items.
