Ever wanted to have functions in the data of your sprite? functions that have _parameters_?

well, this extension adds exactly that!

This took roughly 20 minutes to make, and should be simple to use. For help using the extention, if you copy-paste [this code](https://github.com/c-minusminus/better-sprite-data/blob/master/test.ts) into the js editor in your project, you can see how to use it in blocks.

@AlexK can you edit "function’ into “extension”?

Ahhh. For a second, I thought this was `@richard`’s Improved Sprite Data function still, until I realized it was only meant for data-functions that accept sprite as parameters only. Good stuff!!!

The only thing I find interesting/hard to understand, is the parameter take in, since it shows only shows one reporter parameter, and could get kinda confusing since some would think there is only one parameter? Unless, you explained it or “it” explained itself with the array when you use the run function block.

Woah! How do I use this? I see I can put a function as a sprite data but how do I set and pass parameters? 🤔

</div>

since the parameter is an array, it allows it to be like

```typescript
mySprite.runDataFunction("testFunc", [0, "hello", mySprite, myTilemap])

```

and that would be mostly the same as

```typescript
mySprite.testFunc(0, "hello", mySprite, myTilemap)

```

to factually get said value, you do:

```typescript
mySprite.setDataFunction("move", function (p: any[]) {
    mySprite.x += p[0]
    mySprite.y += p[1]
})

```

Basically, the array is what allows multiple parameters. it can seem confusing at first, but it allows any function. (that doesnt return a value, but I have an idea for that)

</div>

the parameter is an array, so you can have pretty much any mount of parameters, like this:

Ahh I understand in javascript, but what about blocks? It’s just a blank ‘parameters’ variable for me

in blocks, you might need to update the extension for it to be accurate.

Speaking of update…

# You can now return values!

in this update, 2 blocks were added:

 ![Screenshot 2026-09-29 3.53.43 PM](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/3X/4/6/46059d0c8cc423e10c17cf6bc1ee5bfba16f9df4.png)

What do they do? Its pretty simple, the `[return (array of ...)]` is the return block. It returns a value. the `(sprite function last returned)` will contain the data that was lat returned. You can see the 2 blocks in action here:

> **[better-sprite-data test return](https://arcade.makecode.com/S33247-10277-84842-08956)**

@teal256, I saw that you also wanted this, so here!
