Experimentations/getting back into the thick of it.

Hi, I'm back into dabling into some X16 coding after quite a while!

As I'm writting this first comment, I followed this guide (https://www.youtube.com/watch?v=2hE7T_JwV8k&t=0s) and got a sprite to move in basic. Couldn't animate it though.

The sprite was influenced by Falcom's Xanadu (mainly the MSX sprites due to the PC-8801 sprites not being dumped on The Spriter Ressource yet)

I used this program to make the sprites: https://hyperpyxel.com/ . Not having been able to save the file means the sprites only exists in code form now (at least there's the screenshot so you have the idea of how the first sprite came out).

And now, here's the code. Feel free to paste it into your X16 emulator and see it going!

If you have any tips to give me, feel free to reply :D

Maybe I could share some game ideas for the x16 next time.

Have all a nice day!

Animating a sprite means having all the different animation frames in the VERA video memory at the same time, and then changing the memory pointer for that sprite to point to which frame you wish to display.

Technically, it is possible that you could use VPOKE to make changes to the sprite data without changing the pointer, but I think it would probably be too slow to be useful.

Change THIS
1000 REM READ SPRITE DATA
1001 FOR I=O TO 255
1002 READ PX
1003 VPOKE $0,$4000+I,PX
1004 NEXT I
To THIS 
REM VERA LOW ADDR
1000 POKE $9F20, 0     
REM VERA MID ADDR       
1001 POKE $9F21, $40
REM VERA HIGH ADDR, AUTOINCREMENT 1
1002 POKE $9F22, %00010000
1003 FOR I = 0 TO 255
1004 READ PX
1005 POKE $9F23, PX
1006 NEXT

This will load the sprite noticeably faster.

For the rest of the stuff.
Go HERE: https://github.com/X16Community/x16-doc ... 20BASIC.md

Look at the BASIC Commands SPRMEM, SPRITE, & MOVSPR

I change at what line then? The "REM SET SPRITE DATA" section at 1052? Or maybe elsewhere?

In any cases, thanks for the advice.

Pretty much copied your logic. Just so you could follow it a bit better.

Followed the guide: https://x16docs.dreamtracker.org/#index.html
And made test sprites into .bin via this program: https://notin.tokyo/X16tiles/
Here's the resulting code
10 BVLOAD "AZAMTEST001.BIN",8,1,$3000
20 SPRMEM 0,0,$3000,0
30 SPRITE 1,3,0,0,1,1
40 MOVSPR 1,320,200
50 GOTO 60
60 MOVSPR 1,480,200
70 GOTO 40
Main problem here is that the sprites in .bin come out as giberish while it's supposed to be a character (Maybe I've put the wrong values or that the file needs to be named a certain way like all being in caps directly or something like that). At least the mini loop I did with MOVSPR works (I do like the effect), even if I expected translation from a point to another rather than rerendering the sprite from top to bottom so directly.

At least it's sure that I'm least learning, to some extent.

Haven't had a chance to look at your Sprite BIN yet but 2 things. If your BIN has the two byte header you use VLOAD NOT BVLOAD.
(You could BVLOAD to $2998 but that's missing the point...lol) . The second is to make sure that if you exported as 4bpp then your setting 4bpp with SPRMEM or likewise if it's an 8bpp sprite.
