So if I get it right, you can have 2 pieces on one square or so?

Hey, I need to change a sprite from one hex to another during promotion. I DelVar the sprite, then create a new one with the same name, and assign a new hex to said sprite... but when compiling, I get an invalid token error... any ideas?

if you look at the graphics routine, no...

I need to physically change the sprite assignment

this is where I get the error:

sub(M)
If (getKey(54))
If (({Lƒ+17}=19) and ({Lƒ+18}=1))

I'm going to try the graphics addition now...

Hey, I need to change a sprite from one hex to another during promotion. I DelVar the sprite, then create a new one with the same name, and assign a new hex to said sprite... but when compiling, I get an invalid token error... any ideas?

Wait, did you try to do for example this ?
   [<Hex>]→Str1
   .code
   Delvar Str1
   .code
   [<Hex>]→Str1

That is not possible in Axe. I quote shmibs here because he explains very well:

the difference here is that, in basic, STR1 is the name of an external object that is created in ram when the program is running, and can be modified however you choose. in axe, however, STR1 is a pre-processor directive. there is no actual object named STR1 that is created, and it is not used at all by your running program. STR1 is a label used by the compiler to point to a specific spot in your compiled program itself, so you can't tell it to point to two different places at once, which is what saying "store X" -> STR1 and then "store Y" -> STR1 is doing. the first time the compiler sees that, it appends the data "store X" to your program and then labels that point as STR1 for everything else to use. the second line would, then, be trying to append data at a different spot in the program and tell the compiler that that place is also called "STR1", which is causing an issue.

now, all that being said, it's easy enough to modify data stored at an STR#, GDB#, or PIC# label later on, provided that you are compiling a program, that will run in standard RAM space, rather than an application. you have to use the label as a part of a pointer, though, and store all the number values manually. it's much easier to work with free ram areas outside of your own program, like hayleia showed above.

And since shmibs' post tells about one of my post, I quote it too:

It says Duplicate Symbol because you are using twice the pointer Str1.
Note that Str1 is a pointer, not a string, and Axe is not Basic
What you can do is that:
  "STRING1"→GDB1
  "1GNIRTS"→GDB2
Then, when you need the first string, do that:
  Fill(L1,8,0)
  Copy(GDB1,L1,7)
Now, at the pointer L1, you have a null-terminated string with "STRING1"[00] in it
And to get the second string in L1, do that:
  Fill(L1,8,0)
  Copy(GDB2,L1,7)

I want to get the basic mechanics down first

Edit: Hayleia, I have no idea what you mean

I'd recommend having an array filled with each piece. Each piece would then have the following attributes: position and type (from which the sprite and moves could be derived). It'd be a lot simpler than what you're doing right now - that way, you can just swap out the type, subsequently changing the sprite pointers and movement rules.
