Tech demo of my game

[ross]

Wow, nice!

Technically it exploits the characteristics of the Amiga chipset well, several good ideas.

[DisasterIncarna]

amazing stuff considering its a HAM game, great work.

Works flawlessly indeed on A1200+060 now.

This looks amazing! Thank you for sharing your work. If you are up for sharing how it works I would love to see the source. I am brushing up on my C code to try some game in the future. Thinking of doing a port of another picross style game I have the C code for.

Actually I wanted to recommend exchanging samples to sound more Amiga'ish rather than 8bit :P
It sounds nicely, so with fm samples it would start "living" for me.

Regarding the torches, are they intented to be light sources, so floor tiles are darkening gradually from it's source? Or it is just me who saw this feature into the engine? :P

[KaiN]

I could put the whole project and source code on GitHub

Yes, please!

Graphically it now works great on MiST's Minimig AGA core regardless of settings - thanks for the update!


(I just noticed that with faster settings enabled there's an audio issue - some drum sounds are missing. Probably the classic DMA wait problem?)

[Asman]

Great work.

[Silverstreak]

This really is awesome, nice work.

[Zener]

Tried it (in UAE for now). Excellent tech achievement, very impressive!

[malko]

@remz : given usual OCS games that are released, your tech demo is really impressive and burns a lot of limits we have been used to until now.
So : WOW and KUDOS for this tech demo !

After testing your V2 version I can confirm that my "sprite recoloring" bug is gone! Good work!

There is no problem with an A3000/060 when booting the disk. But when starting the game from Workbench, which means data caches and MMU are enabled, I see the same system crash which other 060-owners already reported. It occurs during loading.

There must be some bug, like self-modifying code. I can also confirm that it works from Workbench, when you disable data caches (

cpu nodatacache

) before running it.

Yes, the lighting is precomputed according to torch positions, but the game applies the shading at runtime. So technically it would be possible to have semi-dynamic lighting, like for example lighting up a torch could illuminate a room.

At the moment in this demo however, the lighting never changes, although it is applied in realtime while scrolling.

Thank you for this report: I am unable to repro this audio issue on WinUAE, however I do have the exact same issue on my VampireV4: all drum sounds are missing, right from the start of the song. So definitely something is off when running on fast systems with some specific configuration. I'll investigate more!

Thank you for telling me this: I was able to repro this crash on WinUAE by using this combination-sequence of 6 steps:
- Selecting at least a 68030
- Setting board ROM to "new UAE: indirect mode" (this is required or else the data cache emulation cannot be enabled)
- Enabling data cache emulation
- Enabling MMU
- Booting from HD
- Then launching the game from workbench

If I run cpu nodatacache, the problem disappears; So it seems to be exactly what you are describing. I'll investigate and fix this issue.

I immediately recognized it, but couldn't put my finger on what it was exactly. Thanks!

@remz
In this video at 0:58 the torch's position is not equals with the lightest point, seems the light setting is not properly functioning. Other ones are looking ok.

[ppill]

Update fixed the issue. No more pink on the a1200. Still seeing "garbage" on the screen before the level loads on both machines. No issues when the game fully loads.

Look Amazing and How many Colours on Screen? 256?
