Blocky Skies - My first Amiga game - Page 2

I start the HD version 4 on my A1200 040 3.1. There are some small gfx (sprite?) "errors" random on screen for about 0.1 sec. every n sec.. No music is playing just effect sounds seem to work. When start a game a scrolling background and a playfield (checkboard) + live/score/... on top. When moving the joystick soon a "lose" sample plays but there is nothing to control. I guess there should be a play character or something else?

System clock isn`t restored when quit the game (back to WB). An old known issue. At least on thread about it can be found here on EAB if you need info.

When I starte the game from WB and quit it I get following MuForce hits:

obviously MuForce detects the access of the level 3 and 6 interrupt vectors at $6c and $78

Does the startup code care for the VBR?

Besides that: IMHO this doesn't neccessarily mean that there is anything wrong with it

daxb · 08 June 2016, 16:18

The first 4k are the MMU table here. At least write access to that area isn`t a good idea. Of course I don`t know if the hits are the reason for no music, gfx error, player sprite.

Hi daxb, thanks for testing it for me!

Is this the clock thread?

http://eab.abime.net/showthread.php?t=78592

As for the rest, I think those are the exact symptoms you would get if it failed to install the interrupt handlers.

I need to work out how to install them correctly. I'm guessing there is a vector base register or similar I must use.

Do you know if MUForce runs in WinUAE?

Does the startup code you're using not support this out of the box?

I was just looking at it, and it seems it saves/restores correctly using the VBR, but then my original 68000 code goes and tries to install it directly without caring about the VBR.

Should be an easy fix.

Tsak · 08 June 2016, 22:47

Congratulations guys! Good gfx, punchy music, original theme. A bit hard and unforgiving perhaps (a few more lives and extra time having the path shown would be welcome) but other than that a very well done little game!

When start a game a scrolling background and a playfield (checkboard) + live/score/... on top. When moving the joystick soon a "lose" sample plays but there is nothing to control. I guess there should be a play character or something else?

System clock isn`t restored when quit the game (back to WB). An old known issue. At least on thread about it can be found here on EAB if you need info.

When I starte the game from WB and quit it I get following MuForce hits:
-- snip --

I ran MUForce on an Amiga4000 configuration in UAE and the game didn't work (no sprites/music), but the behaviour wasn't exactly as you described, I got the same MUForce hits.

So I updated the init code so the interrupt handlers are installed via the VBR and now the game run perfectly with no MUForce hits (On an emulated A4000 with MUForce running).

Could you try test version 5 and see if it fixes it for you on real hardware ?

I still have to get the system clock restore stuff working.

Thanks again for the testing - now i know about MUForce and how the system clock works - very handy

Thanks for the feedback. There will be some easier levels (and some that are so hard it's evil

) in the final release, so stay tuned

Each level has different settings, player speed, the speed before the pathway fades, the speed the pathways fades, speed of the bees etc. So I will definitely consider this feedback when I am developing the final set of levels to make sure there is a good cross section of difficulty.

alpine9000 · 09 June 2016, 07:56

I uploaded test version 6 to http://blockyskies.com which includes code to restore the system clock on exit for the hard drive installed version.

I used TOD code adapted from this post (it had a minor bug in it) and it seems to work well for me in all of the emulated configurations I can test (including no RTC).

If anyone is game to test it on real hardware with a RTC, I would be very appreciative

Asman · 09 June 2016, 08:38

@alpine9000
I don't catch this. Why you must store and restore the system clock ? I never do that in my DisableOs routine. Also I don't see that you takeover blitter in proper way, mean about graphics.library calls like OwnBlitter and DisownBlitter, or I'm missing something.

I guess because I disable all interrupts and use only two custom interrupt handlers, the CIA timer interrupt will not be called and the system clock is not updated? This thread has all the info I know about it.

As for the blitter ownership, I am not really sure about this either as I just used Photon's startup code which doesn't do it. I had read in HowToCode5.txt they recommend you Own/Disown blitter but as it seemed to work fine without it I didn't add it in. I wonder if it's possible you only need to OwnBlitter if you leave process scheduling enabled ?

The reason for 'owning' the blitter is, that the os could be in the process of setting up a blit just as you disable everything. This could cause the blit to go haywire once you enable everything again, because you probably modified some registers.

Wow; sounds great alpine9000

Also, I take it that the floppy and hard drive versions are exactly the same in terms of graphics / sounds / features etc?

Makes sense, no idea if it's doing anything.

I did:

Code:

        move.l  a5,a6		;gfxbase -> a6

        sub.l   a1,a1           ;blank screen to trigger screen switch                                                            
        jsr     -222(a6)        ;on Amigas with graphics cards                                                                    
        jsr     -270(a6)        ;WaitTOF                                                                                          
        jsr     -270(a6)        ;WaitTOF                                                                                          
        jsr     -456(a6)        ;OwnBlitter     

        ... ; game code always waits for blitter before use.

        move.l  a5,a6		;gfxbase -> a6                                                                                    
        move.l  (sp)+,a1      	;previously saved view                                                                            
        jsr     -222(a6)        ;restore OS screen                                                                                
        jsr     -270(a6)        ;WaitTOF

        jsr     -228(a6)        ;WaitBlit

Yes - the only difference is the hard drive version has a quit menu option.
