Re: Image mapping : Peer review needed

It's soon the week-end.

The sky is blue and the grass is green on Oric Planet.

Re: CC65/C: Ensure joystick press is registered only once

Please note that over here I presently have a hybrid setup of CC65 working under Windows Subsystem for Linux with OSDK working under Windows. So that is why I have MAKE files for the CC65 part and .bat files for the OSDK part. To do is to integrate that in one workflow somehow (probably by using th...

Full source code here: https://github.com/xahmol/ludo/tree/main/Oric%20Atmos/CC65 Super mega cool !! Thank you xahmol for sharing this game and its source. I had already played the basic version and it seems to me that this one is a somewhat more responsive. I casted a quick glance at the source co...

Re: Wolfenstein / DOOM for Oric : has this been done?

- clearing the viewport in a more efficient way, Done !! :-) Fast viewport clearing give the impression that the whole stuff goes faster. I've just tested on a 40*40 texels viewport and I find it reacts smoothly. There's still a sweep effect when scene draws (and I think I can't avoid it as long i ...

Re: Wolfenstein / DOOM for Oric : has this been done?

- Other? For castoric, I use the 6 least significant bits of a byte to encode the color of a pixel (in texture) /texel (on screen). The 6 bits are composed of three groups of 2 bits for each Red, Green and Blue components. I will try to try it as soon as possible :) It's cool :-) I've just pushed s...

Re: Oric extender - a basis for DIY projects and experiments

:wink: Hey .. Looks like a new hardware is about to born :-) I wonder why mankind has lost of sight the wonderful wire-wrapping technology : https://en.wikipedia.org/wiki/Wire_wrap Some handmade electronic board have worked fine for decades with wirewrapping. Any way, most important is that you man...

Re: Wolfenstein / DOOM for Oric : has this been done?

Perhaps I don't know the right parameter. When I run this command on the 32x32 pixels texture : https://raw.githubusercontent.com/oric-software/castoric/main/img/bluestone.png castoric>%OSDK%\Bin\PictConv.exe -o2 -o3tabtext img\bluestone.png fic.h I obtain this: unsigned char tabtext[192]= { 0x40,0x...

Re: Wolfenstein / DOOM for Oric : has this been done?

Oups .. I may have confused with PictConv I was thinking of a tool delivered with OSDK which generates C or asm buffer from image file. And I don't know why I thought it was PictOric. The goal is to transform image texture file from this directory (which are simply 32x32 pixels) into buffers such as...

Re: Wolfenstein / DOOM for Oric : has this been done?

You're totally right. And I realise that the library is now called Pillow rather than PIL. https://pypi.org/project/Pillow/ pip install pillow I recommend last version of Python (3.9) but it should work from Python 3.7 or 3.8. I am having a very limited access to internet at the moment so I can't up...

I forgot to say: Walls can't be longer than 24 units and must be either (O,y) aligned or (O,x) aligned (i.e their extremities point share either the same X or the same Y coordinate). For longer walls, one have to create several walls one beside the other and sharing a common junction point. There's ...

Re: Wolfenstein / DOOM for Oric : has this been done?

I wonder if this would be usable for a flight sim, too .. Raycasting is not the most appropriate technology to create a flight sim. Lib3d used in 1337 is the most adapted tool to create a flight sim beause it has roll angle. So cool :) Congratulations ! We are waiting :) I pushed source code and so...

:shock: Nice ! thank you ;-) I'm glad you enjoy :-) Probably impossible to get to 14 fps which could be needed for a FPS, but a nice dungeon crawler could be done with this... Congratulations! Yes ..
