I have already implemented these in the extension this topic is for. The code is in here:
>
lines 407 - 433:
```auto
/**
* Draws text on an image
*/
//% block="Print text $text on $target at x $x y $y color $c font $font"
//% blockId="extras_print_text"
//% target.shadow=variables_get
//% target.defl="picture"
//% font.shadow="extras_font_selector"
//% group="Text"
export function print_block(text: string, target: Image, x: number, y: number, c: number = 1, font: image.Font) {
target.print(text, x, y, c, font)
}
/**
* Draws centered text on an image
*/
//% block="Print centered (x) text $text on $target at y $y color $c font $font"
//% blockId="extras_print_center_text"
//% target.shadow=variables_get
//% target.defl="picture"
//% font.shadow="extras_font_selector"
//% group="Text"
//% weight=1
export function printCenter_block(text: string, target: Image, y: number, c: number = 1, font: image.Font) {
target.printCenter(text, y, c, font)
}
```
You can copy this if you wish.

It is not possible with the tools I have available, but you could try out the [Block Objects extension](https://forum.makecode.com/t/tutorial-what-are-block-objects-and-how-to-use-them/24274) for a similar effect.

maybe the `public` and the `private` commands I don’t really know if its possible I don’t use them maybe also `const` or `var` maybe even `let` but maybe those two wolud be dumb maybe the `Buffer` command like `image.Buffer` if theses ones help

I may be missing something but the demo game doesn’t load, and even when I try to edit it, it doesn’t show the shaders

Yep! I can see that too. I’ll look into it.

Hi, and thanks! I’ve been using makecode for a bit longer but just joined the forums some days ago, and I’ve already seen some really cool stuff here

Do you mean image.ofBuffer? That would be the only one on this list that is possible to add.

Ok, looks like this one should work:
> **[pxt-javascript-extras - Copy](https://arcade.makecode.com/S59613-44143-12427-37578)**
>
> Shader test project
Mods could you replace the seemingly broken link with this one? Thanks! \<3

It does! Given the ability to change the shadow colors I see a lot of potential in this

Is there a reverse image to buffer function somewhere? Because I went as far as to look at @Sarge’s Better Settings extension to see how he stores images and he does it manually and doesn’t use ofBuffer at all…
I will definitely have to investigate how it works because the few uses I tried didn’t quite work.
