Hello! I’ve been experimenting with some of makecode arcade’s hidden functions, and I’ve made a list of mini extensions and functions for you to use!

## Functions

> **String Functions:**
>
> > ### Description
> > 
> > These functions are for more advanced uses of strings.
> 
> * * *
> 
> ### String to uppercase/lowercase
> 
> **Uppercase:**
> 
> ```auto
> helpers.stringToUpperCase("lowercase"): void
> 
> ```
> 
> **Lowercase:**
> 
> ```auto
> helpers.stringToLowerCase("uppercase"): void
> 
> ```
> 
> * * *
> 
> ### String is empty?
> 
> Checks if a string is empty, returns true if it is
> 
> ```auto
> helpers.stringEmpty("string"): boolean
> 
> ```
> 
> * * *
> 
> ### Replace all
> 
> This function finds all instances of `to replace` in `string` and replaces them with `replace with`
> 
> ```auto
> helpers.stringReplaceAll("string", "to replace", "replace with"): string
> 
> ```
> 
> Alternatively you can use `stringReplace`, but that only replaces the first instance of `to replace`
> 
> * * *
> 
> ### Slice
> 
> This function gets a substring in `string` from `start` to `end`
> 
> ```auto
> helpers.stringSlice("string", start, end): string
> 
> ```
> 
> Another alternative is `helpers.stringSubstr("string", start)` , where it gets the letters from `start` to the end of `string`
> 
> * * *

> **Search Function:**
>
> > ### Description:
> > 
> > These functions search for a specific thing by name. Returns `null` if nothing is found.
>

> 
> #### Search for song
> 
> ```auto
> helpers.getSongByName("mySong")
> 
> ```
> 
> * * *
> 
> #### Search for tilemap

Thank you to the makecode arcade team for implementing these functions, I’m just showing them to you.  
More to come in the future!

This is super cool! I think I’ve found a glitch with the Info+ extension though. When I download the extension, my game won’t start, whether I’m actually using the extension blocks or not. The problem seems to be coming from a duplicate file that already exists in the game. I think if this file is removed in GitHub, the extension will work.

Fixed! I deleted the file, but it gave me all sorts of errors so I restored it and it worked!

### Two More Functions!

#### 1. Rotating An Image

This function rotates an image by `degrees`

```typescript
image.rotated(degrees): Image

```

This is a MUCH better alternative to complicated workarounds.

#### 2. Console Priority

This function adds a listener to the console, meaning that every time that something is logged in the console the code runs.

```typescript
console.addListener((priority, text) => void): void

```

This code seems very complicated, so let me break it down for you.

1. `(priority, text)`  
These are basically variables to use later on in the code, which means we shouldn’t edit them.

2. `() => void`  
`void` is just the script to run after the message is received. The best way to use it is by replacing it with:

Now that I’ve explained it, here’s how you can use it in your own code:

```typescript
console.addListener((priority, text) => function() {
//code here
})

```

Now we can monitor the console using plain old JavaScript.

An example of how we can use this in our code is:

```typescript
console.addListener((priority, text) => function() {
    if (text == "score+1" && priority == ConsolePriority.Log) {
        info.changeScoreBy(1)
    }
})

```

In this case, every time a message is logged the game checks if the message is `score+1` and the message type is `ConsolePriority.Log`. If so, it changes the score by 1.  
_PS: YOU CAN REMOVE A LISTENER BY COPYING THE SCRIPT THEN REPLACING `addListener` WITH `removeListener`._

Now when I use the URL to download the extension, nothing shows up.
