Axe Questions/Routines *Come here!*

Glad to see your progression Sorunome Smile

pointers are indeed very important, and without knowledge of them you won't be able to make much in Axe, or possibly in the future for you, Assembly. Do you have any questions now that you've read up on them?

On a side note, didn't BrandonW make a USB driver before that everyone seems to use? If he did and I remember correctly, I suggest using that; working with it in Axe will likely inflate your output binary size and be a pain to work with, but at least a decent amount of the work would have been done for you already.

I got a different question: How do you make/use subroutines? I just know that at the beginning of a subroutine must be Lbl (I think) And at the end RETURN. But I don't know how to call them, or am I even wrong with that?

You use labels to create the subroutine, and you call them by using sub(<label name>). For example, if you have a label named ABC, you would use sub(ABC).

And, to access the arguments, you use r1-r6 (found through [Vars][Right][3]) inside the function. For instance,

I get it! Thanks a lot! And I have straight away my next question! Razz

Well, I got this code:

I'm going to go against your instructions and tell you that you need to do hexadecimal with Pt-On(. If you don't want to use hex, then do this:

I'm not using Pt on, i'm trying to diysplay that sprite out of a binary code, and that doesn't work.

You shouldn't be trying that! It's just a bad idea. If you want to use binary, change this line:

what does ΔList( do?

It is the same as [], but allows you to list numbers that aren't in hex. It gives you the ability to use binary, because this:

Oh, I think I get it. Is it then still possible to just change one "1" to a "0" easely and the other way round?

What do you mean? You can always use bit-level instructions in assembly, but I don't know what you are trying to accomplish.

A sprite editing program, and for that i need to change some 1s/0s while the program runs

What I did for mine was modify the screen using Pxl-On and Pxl-Off, then copying the data from the screen buffer. However, I do have a very good sprite editor for Axe out there, that will export sprite sheets into Axe-ready include files. You can get it here. We all know that the community doesn't need another sprite editor.

Well, I want to make that the sprite editor can make grayscale sprites

The one I linked you to does both grayscale and black+white. Also, moar grammar.

Ok, Then I use yours. And sorry 'cause of grammar, I'll try to do better. Smile

Well, another thing: how does Pt-Mask work?

I'm not sure. I've never used it; I prefer to resort to alternative means of masking sprites.
