Hi!
I have a number of questions, that I hope you can answer š
ā¢ I need to load text from the README.md, or any file in the MakeCode Arcadeās Explorer, but I canāt seem to find the right feature.(And I donāt know how to use `settings.readString(key: string)`)
ā¢ I am producing a sort of RPG game, kind of like Pokemon, and I need sprite collision. -Meaning, when the player `overlaps` another sprite, it will just keep the player in the same position until the player walks away, or into another direction.
ā¢ I need to send data to another player when a connection is successfully established; e.g. if the players decide to trade $5 and x1 Water Bottle, then it should send over the items, and remove the correct items / cash from the playersā inventory.
Any help is highly, highly appreciated š

- `settings.readString` stores the string in the devices flash memory; this will let you save the data to the device. hereās a quick example of using it to store a message for future players (like you would save data, so that you could save the data as the player progresses, and try to read it whenever they reset the device): [https://makecode.com/\_3uF6WxXu9VX7](https://makecode.com/_3uF6WxXu9VX7)
- You could handle it with overlaps, it might be a bit tricky though - you would probably end up wanting to figure out which direction the player is coming from (based off their velocities), and reset the position to be opposite that direction when they hit one of the sprites - e.g. if the player is moving right and they overlap an enemy, set the playerās `.right` position to the enemies `.left` position: [https://makecode.com/\_15bRj9cL5crA](https://makecode.com/_15bRj9cL5crA)
other potential approaches:
- make the other āspritesā walls if they arenāt moving, and let the physics take of them / handle the collections with wall collision handlers.
- the [tileworld](https://forum.makecode.com/t/arcade-tileworld-extension-and-demo-boulder-game/659) extension handles things like this nicely by aligning sprites to the grid, but Iām not sure if the current state is fully stable / if there is any documentation (@tballmsft). Also, the extension linked in that post is a bit older; now located [here](https://github.com/microsoft/pxt-tileworld)
(re: hardware multiplayer, I havenāt personally interacted used it / made any multiplayer games on hardware yet, and there will likely be more iterations before that part of the codebase is fully stable)

Joey, this is extremely helpful. But I have a questionā¦ Can I save multiple strings, without them overlapping each other?
I want to save name and score, not only one string.(Would be pointless š
) Any ideas on this? Thanks š

Yes - the ākeyā is like a file name in this case, so if you need to store a name and a score you could use two keys - āmySavedNameā and āmySavedScoreā - and then it will store the two values separately, and you can read them using those keys. (Going of the example above, just make unique names for each thing you need to save / read, and use each of them like I did `myKey`)
Just a note, if you store too much at once and it runs out of memory, the current behavior is that you will get a crash with a 920 error, and the data will be wiped on the next load.

Yes, use the āsettingsā extension. Click Advanced -\> Extensions -\> settings.

@peli, do we have a blocks extension for the settings? I donāt see it either. The APIs are available in JavaScript without any additional packages

Oh snap we probably donāt. We also donāt have blocks to store data into the sprite data object which is very annoying. We need an create an extension for this.

Oh! Yes! My son was working on his own āGalgaā and was making different kinds of enemies. He wanted the bigger ones to take two hits, but I didnāt have any good suggestions for how to track their health.
He decided to just spawn a maximum of one per screen, which workedā¦ but itād be excellent to have support for sprite-scoped data.

Iāll spin an extension for the sprite data.

Thanks! Looks really useful. Looks like thereās one small problem with the comment above `readDataAsString`. I created an issue: [https://github.com/pelikhan/sprite-data/issues/1](https://github.com/pelikhan/sprite-data/issues/1)

@Blobiy I just created a settings extension for saving game data. Check it out [here](https://forum.makecode.com/t/settings-extension/1594)
