Okay. I was wondering how I would have to change something in a GDB(that I use as my map) during my program is busy. For example, say I break a block or something, I will wan't to change that number in the GDB to another number so when it loads the screen it's not there anymore. Any ideas?

If you want to change an array's length, then just have a variable such as L be the length, and L1 be the array. then to use the array, just do:

For(A,L1,L1+L)
.Code goes here, where {A} is your array element.
End

To add an element to the end:

L++
byte->{L1+L}

To remove an element from the end:
0->{L1+L}
L--

There are ways to add/remove elements from inside an array with the copy() command, but that's more advanced.

Do you have a tile that isn't anything (or is, say, floor)?
Say it's zero, and the map is 12*8 (typical 8*8-tile map) and stored row-by-row...

Spoiler For code:

.if you have number for tile instead of X,Y
.say number is N
N/12→Y
N-(Y*12)→X
.X and Y are # tiles counting from zero from the left/top edges respectively
.assuming it's 1 byte/tile
0→{Y*12+X+GDB#}

Ofc variables can be changed so they don't overwrite X and Y

So it isn't impossible to overwrite a number at a GDB at a certain point, like this:
:[01010101010101]->GDB1
:2->{2+GDB1}
That would make that GDB1=01010201010101Or am I mistaken?

That is possible, but that is called 'self-modifying code' or 'writeback'. The thing is, that you cannot use it in an app. The best way is copying the map to L1 or another place in RAM.

So I copy the code to GDB 2, for example and edit that one?

Nope, you should copy it to some place in RAM that you can edit freely, then delete it afterward (My tip: use an appvar)

Okay, thanks guys. I'll look at that.

Fixed it nvm

Doesn't crabcake require you to exit in a very specific manner?

What is the maximum program size? I'm at 7000 bytes now.
