Which is the fastest ? use a one screen size buffer for all sprites or many buffer of sprite size I never used many small buffers I always use the big buffer and then I have two options, 1. I copy all the buffer to the screen at each game look iteration OR 2. I just copy what changed since the last...

Re: double buffered sprite engine ?

I am sorry although I can understand written formal French I can't explain this stuff en Français :( I am not using a buffer for each sprite, I use a big buffer where I paint the game screen, with tiles, sprites, objects etc. And then I copy the the buffer to screen after finishing updating the buff...

Re: double buffered sprite engine ?

Looks pretty smooth .. what did you mean by this, though? >- paint the masked sprites (pixel data and masks are pre-shifted) to 6-bits, or .. ? For each sprite I need to store in RAM the gfx and mask for 6 possible positions as we have 6 pixels per byte on the Oric (this allows the sprite to move a...

Re: double buffered sprite engine ?

Hello, Unfortunately I have not published any code of mine yet. The sprite engine does this basically: - restore background for each sprite - save background for each sprite - paint the masked sprites (pixel data and masks are already pre-shifted in RAM) - copy buffer to screen - calculate sprite da...

Re: New game project

Why not use PictConv on a hires image and see how it handles the dithering process? I second that. Draw/compose a nice picture without thinking about color limitations & let converters do their best. Here is what I can get with PictOric with google images about "stealing potions" x.pngy.png Thank y...

Re: New game project

I am sorry that everyone found my effort so terrible although I said it still needed a lot of work. I just wanted to show more or less the idea for the presentation screen.

I will be thinking on what to do about this.

Oh noes I don't feel very comfortable to share this but here it goes...

Working on the loading screen, it is not an easy task due to the artist's limitations in pixel art and the hardware restrictions :) This still needs a lot of work.

Re: New game project

The blitting is so smooth I can hardly wait to get my hands on this and find out how you did it! :) I don't think I am doing something special, (as I have answered on YT), I have a backbuffer and then use the dirty rectangles technique to blit only what is altered in the buffer. I use unrolled rout...

Re: New game project



Update:

- baddies Gfx and movement

Yes. Graphics are really nice but I am quite surprised about how smoothly it moves.

Congratulations!
Thanks Chema, I was a good surprise for me too, having everything unrolled payed off it seems.

Re: New game project

Hello,
I am sorry for the long hiatus.
I think that not all is negative about the quarantine as I am back doing some retro coding due to this unfortunate pandemic situation.

Its a platformer - cool! - but it looks a little Chucky Egg'ish. Is that the plan? You have to collect the eggs in a certain time or a specia...
