Creating shoot them up
Re: Creating shoot them up
Hi.
Your .pce works fine but i can't compil the .s
I don't have the the HUC part. I try with the original HUC kit of magicengine and after with the last version of HUC on the zerograd web site (Download HuC 3.21 (denki) (433975 bytes), OS : win added on 2005-04-09). I've verified the path and make some test without success.
With the last kit (huc 3.21), when I try bg.s, I always have this error in huc_gfx.asm with all line with " __plb" if I test the line number.
The message is :
"lda __arg,Y
undefined symbol in operand field !
And I try with samples in mkit, I have now error when I use them with HUC 3.21 (in startup.asm, Library.asm and sound.asm)

Re: Creating shoot them up
I finally make it without HUC and some minor change.
One thing I change to make my version working is .org :
Can you tell me why I need to write at these address ? I don't find information in your last link.
And after if I want to go to BG1 and/or scroll, I need to look into the register "$09 - Memory Width Register (MWR)" ?

Code: Select all
.data
.bank MAIN_BANK
.org $C000

Re: Creating shoot them up
That's mainly because of how mkit implements the irq_reset.
I don't have the code at hand right now but I guess that it maps the MAIN_BANK to mpr 4 (hence the .org $C000, as 0xC000=(6<<0x0D))
About the vdc registers... yes!
I think there's a routine for this.

Re: Creating shoot them up
Thanks, I look Inside mkit/debug and find some value. I think I put now my data in the good way but ...
I doesn't understand why you mul by 0x0D but I find the bank map adress and 6 is for the bank 6(#C000) !
I begin to use the BG0 but line by line with a mini function of my own. Not terrible but working.

I wish to use more dynamic value. I use st1 and st2 but I can't put variable Inside, only hard number. The base of my minimal function (not a real function but a boucle, I don't know if we use boucle in English)
I have another problem : I can't put my tile in BG1, I try with vreg #$05 without success. The same for my sprite. i want to change his priority to go on Sprite1 plane.
I use the macro : spr_pri #1
I try to change value #1 or #0 but the asm always put it on Sprite0 plane. I can't test with a background tile in foreground but the psrite disapear when I hide the Sprite0 plane with Mednafen.

Re: Creating shoot them up
st0, st1 and st2 are "shortcuts" for:
mkit has aliases for vdc registers. Namely, $0000 is video_reg, $0002 video_data_l and $0003 video_data_h.
They can be found include/pce/equ.inc
Do you call "update_satb satb" in your main loop?
Code: Select all
; st0
lda something
sta $0000
; st1
lda foo
sta $0002
; st2
lda foo
sta $0003
They can be found include/pce/equ.inc
Do you call "update_satb satb" in your main loop?
Re: Creating shoot them up
Thanks a lot for the shurtcut.
I make it works right now. I just look now for array value to make my tilemap.
I found the aliases you talk : video_reg ... I will look tomorrow how I can use them (with the debugger). i juste want to choose my plan for drawing sprite/tile now.
And oh yes, I update my satb

Not the best place for programming but many shooter fans in one area.
Thanks, I'll look in the dev section, maybe to find some informations on good shoot sharing.
