BUTTON(number) returns the button code. It's a binary value, with bits corresponding to buttons. 1 for up 2 for down 4 for left 8 for right 16 for A 32 for B etc... But SmileBASIC also includes constants such as #UP, #DOWN, #A, and #L that store these button codes, so you don't have to memorize them if you don't want to.

ACLS takes about a half a second to execute. You could just use CLS.

Because of the way raycasters work, you cannot create more than one layer of blocks.

I partially agree. I like them both equally. You can have unlimited programs with QR codes, but scanning them is a chore. Cloud storage is easy, but you need internet access and you have limited storage.

IF GUY < -1 THEN Less than -1? I think you mean greater than -1. They removed the QR code system because you can now upload projects to the internet and get an 8-character key instead of QR codes. Nice program, by the way.

CHR$(character code) There are lots of character codes. Those characters start at 57600.

Well we already have a raycaster.

Yes! It adds so much more. User-defined functions are especially awesome! The upgrade is definitely worth it.

I consider HTML to be more basic than BASIC. Shouldn't be too hard. Just different.

HTMLBASIC is a primitive version of the HTML(HyperText Markup Language) code that is used to make websites. HTML is also associated with CSS(Cascading StyleSheets) which edits the placement, color, background, and other attributes of HTML elements.

Well, having downloaded your program, I now feel stupid about SPANIMATE because I didn't know that negative numbers in the time parameter meant smooth animation.

A couple minor bugfixes and changes for 3DENGINE and two new libraries. SPANIMATE-Smoother movement animations than SPANIM. HTMLBASIC-A primitive HTML thing, with primitive CSS.

There's a "PAGE NEXT" button in the in-game help feature if that's what you're using.

You don't have to use SPDEF. There are multiple ways to use certain commands in SmileBASIC like SPSET, which can be SPSET Management number,Definition number SPSET Management number ,U,V [,W,H] ,Attribute SPSET Definition number OUT IX SPSET U,V,W,H,Attribute OUT IX SPSET Upper limit,Lower limit, Definition number OUT IX SPSET Upper limit,Lower limit, U,V,W,H,Attribute OUT IX

(#SPSHOW OR #SPREVH) also does the same thing. So does (#SPSHOW+#SPREVH)

Why is that second 1 there? It isn't listed in any of the SPSET definitions in the reference. Take it out and you should be error free.

I make arrays to hold data and program my code to do different things with the different indexes. That is what a struct is, right?

The value is binary. The different bits in the binary number mean different things. The # things are system constants. They're pretty much just variables. The first bit is visibility, and can be represented with 1 or #SPSHOW. The one that horizontally flips it is 8 and has a system constant of #SPREVH. You'd want (#SPREVH OR #SPSHOW). If you want to do it in decimal, that would be 9.

Slot 4, line 27 is where it says the issue is. Look there.

BGOFS layer,x,y,z There's no time parameter, so you'll have to offset it every frame to make it scroll smoothly. The coordinates are the screen coordinates of the top left pixel of the background layer, so if you want it to go to the left, you'll need to use a negative x coordinate.
