UInt32 and such don’t exist, it always throws an error. ---

HI STUDIO AGAIN! i want it so in raycasting extention, non-walls are the floor. maybe a sky colour too. maybe a block like [Replace all {Tile} with {sprite}] I think it would be handy if you have a lot of coin entities to make (like in my game “Ninja Legends”) ---

Many AIs output markdown, so when you copy to clipboard it gets copied as rich text, and discourse uses markdown so it’s almost a perfect copy (able to understand all the rich text) > [@VoxelMaster64](#): > > a way for makecode to tell a function runs instantly, so that code would be more optimized. I doubt MakeCode does a similar thing to scratch where it runs functions with a screen refresh unless specified not to. ---

I think non-walls already are the floor? If you want a sky color then set the background color to that. that block does exist, it’s in the “tile utils” extension ---

Not really built in but you could have a function that stores the current countdown time and keeps re-setting it every frame (I haven’t tested this, however.) ---

> [@UnsignedArduino](#): > > Well yeah, in primitive JS use, you don’t need or use them? What’s the purpose of needing a specific-sized int? You could use makecode’s fx8 Fx8 is a namespace/interface to handle 8-bit numbers, i still waste like 56 bits (64 bit float - 8 bits)! a Uint8Array would have no extra memory though. > [@UnsignedArduino](#): > > I doubt MakeCode does a similar thing to scratch where it runs functions with a screen refresh unless specified not to. I don’t really understand what you mean? But take turbowarp for example. It is just scratch but like 50x faster. I copy-pasted my raytracer into an actual js compiler, and it ran SUPER fast. (only the main function and controller was changed, not the hitbox collision or raytracer or player or anything else.) On my computer, a 140x140 on makecode ran at 14 FPS. the actual js, I had a 900x900 (81 times bigger) and it still ran fast (20 FPS)! I think the best keyword to make makecode not compile a function into a huge switch would be “sync”, like `sync function add(a: any, b: any) { return a + b}`, since makecode compiles because it doesn’t know if a function pause the thread or not (e.g. `pause(...)`, `waitUntil(...)`, etc.). so if my functions were actually something like `sync function traceRay(...)`, my raytracer would become roughly **53x faster.** (also i dont think i said this yet, but im making a topic on how makecode compiles.) ---

`(3 || 4)` is also perfectly legal syntax. I was merely quoting the OP. ---

> [@VoxelMaster64](#): > > Fx8 is a namespace/interface to handle 8-bit numbers, i still waste like 56 bits (64 bit float - 8 bits)! a Uint8Array would have no extra memory though. Fx8 is fixed-point arithmetic, no? Probably would need one of the engine devs to chime in but I was under the impression that the 8 is for 8 bits of decimal points, and 24 bits are used for the regular integer part. > [@VoxelMaster64](#): > > I think the best keyword to make makecode not compile a function into a huge switch… Ohh, if I’m not mistaken then I guess you are talking about the compilation that happens to the code to result in binary.js so it’s a bunch of state machines and a “performance-killing” trampoline - I _think_ it’s in the [continuation-passing style](https://en.wikipedia.org/wiki/Continuation-passing_style) so V8 can’t JIT compile/optimize/inline/etc. it well so it’s “very” slow compared to if it was just regular JS. And for that, I would definitely want the MakeCode team to speak about that instead but my guess it would be very hard to have a “synchronous” function emitted as-is while keeping the rest untouched. Probably the only real solution is to implement more shims that handle intensive math so it doesn’t need to “bounce around” or something like that. Or compile natively something like @Kikketer’s [native builds](https://forum.makecode.com/t/i-present-native-linux-builds/45115) or implement the pxt64 bytecode interpreter (which I’ve been researching as well…👀) ---

it’s ```typescript function hypot(y: number, x: number) { return Math.sqrt(y*y + x*x) } ``` its easy to make, but having it in pxt makes it slightly faster (a tiny bit, but in huge loops it makes a difference) ---

Add a new parameter which are called “labels” to functions. A label parameter can be used to define the inputs in a function to help makecoders understand their input in a function easier. You can change the name in the function editor but, not in the workspace.
