Whoa! This is cool! How did you manage to record a video and get it on makecode arcade?

could you dum down what’s wrong sorry I just don’t know what your saying but shawdo is for stuff like

```javascript
//% mySprite.shadow=variables_get
//% mySprite.defl=mySprite
//% block
 export function foo(mySprite: Sprite): void {

}
}

```

It would look like this

It would look like this in the blocks

I don’t intirely remember but I think it had to do with pre-setting the variables using defl and shadow, and constantly having to switch back to blocks to view my changes

well when I make extensions and I need a variable global I just do let Variable = 0 at the top under the namespace

I tried rendering a 200x200x200 with a completely random block generator.

IT WAS SO FAST. because it used raytracing, it was exactly the same speed. yes, there were 8,000,000 voxels. no, I did it on a SLOWER computer. This is the power of raytracing.

Also: just an idea: make the cursor (through browser extension) determine where the player is facing, and the arrow keys for movement

The random generation takes a few seconds, but the rendering is FAST. it is 8 million voxels, so trying to save it with the settings extension WILL NOT WORK.

the only issue is that it doesn’t have a way to set the cursors position or loop. you know how with Minecraft you don’t see the mouse and you can pretty much turn around infinitely? either the mouse is looping around the screen or it’s being set back to the center of the screen. @richard, do you think it would be possible to add setting the cursors position or making it loop around the screen, and also something to hide/show it? it would be very helpful for things like this.

Also please note that it doesn’t do much. the world is pre-defined, and there is a glitch I noticed. It is still MUCH in development, and am still working on it
