Pseudo pixel game prototype.
Pseudo pixel game prototype.
After making the font, i decided to try if it could also be a game with these 16 characters.
it's just a prototype, I don't know if it will become a finished game
Here is the result:

Re: Pseudo pixel game prototype.
At first I was like, "wtf rax, you turned my Oric into a ZX81" but then I was like .. 'but you could add colour!'
Cute graphics, neat engine and some interesting potential .. curious to see about that colour, though.

Re: Pseudo pixel game prototype.
Yes! The desired effect was close to the ZX81.
Here's a pathetic attempt at coloring. I think it can be a hundred percent better, but it needs a lot of work .
(there are also glitches that I couldn't easily fix).

Re: Pseudo pixel game prototype.
Well, it ain't no SWIV, but its surely something that I could see evolving to be a very playable shooter... whats with the top-line character mess, though?
Re: Pseudo pixel game prototype.
Top-line character is a glitch. I didn't have time to fix it.
I'll never be able to do anything like SWIV. I had started something similar and never finished it.
Re: Pseudo pixel game prototype.
Thank you very much Rax for the realease of this source code.
As usual with your code I find it is neat, inspiring and so smartly designed that it is enjoyable to read.
Big Up !!
I made a little screencap of the color version with my new friend the Oric 2.5 animated gif feature :

Re: Pseudo pixel game prototype.
Very very cool demo ! So 8bitish
There's magic in LORES 1, might inspire me !
What tool did you use to convert the png files to .c data (https://github.com/raxrax/oricOsdkPseud ... ster/res.c) ?

Re: Pseudo pixel game prototype.
I don't know what tool master rax used to convert PNG into .c array. But I can show you some similar things written in Python.applepie wrote: ↑Fri Dec 23, 2022 6:38 pm

Re: Pseudo pixel game prototype.
on my side, i've discover this lores mod with Rax post.
Then going deeper on the subject, based on std alt set, i've created an excel file to draw a lores pic, and generate some basic lines & c description of the screen

Re: Pseudo pixel game prototype.
In case it can help, I had made a little tool to generate alternate charset from images.
It take an area from a black and white image in 240*224 pixel and create a charset to reproduce this image (and optimize the chaset size by reusing already defined characters).
The generated C code uses this function that changes an alternate character in the Oric memory:
And here's the python script that create an alternate character from a preformatted image and generates the code to put the alternate charset in the memory and displays the image on the screen.
From an image below (240*224 px to match Oric screen dimension):
it generates the code:

Re: Pseudo pixel game prototype.
But the most stunning stuff I have ever seen about the alternate charset is master rax's H3 LIB
https://forum.defence-force.org/viewtopic.php?t=2186
Dynamically changing alternate charset to create a graphical area within text screen .. just amazing ..

Basically, each time you see the same effect duplicated on the screen, it's most probably using charsets reconfiguration instead of HIRES
