Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

That gives me the idea to write a "ASCII ART Version" for VT 100 Terminal.
Somehow ZX81 like but with Colors


Excited / inspired - but I dont need another side project battling with the day job ;-)

3D Monster Mace   ... The problem is, that on VT100, you have not charset with those "Quarterpixels" like the ZX 81 had

More Like this:

For PicoMite nonVGA in Terminal..
(runs on a bare Raspberry Pico with MMBasic in VT100 Terminal)
CPUSPEED (KHz) 252000 (13.8 FPS @ 127000 KHz)

(will also run on PicomiteVGA in Terminal but much slower when the Line "Option Display SH%/8,SW%/4" is deleted and Prints garbage on the VGA Screen because it cannot process the VT100 escape sequences)

back to the original listing.
The empty road is a little boring.
For this reason I've done some Pixelwork and designed a car which can be integrated into the original listing.

  stanleyella said  Sprite read needs to be blit read for non vga mmb. I will try but it is a big sprite.

actually this are 2 Sprites in one... The right Side is a little different from the left Side.
Since the car is symmetrical, I only read half of the car with each sprite and then draw them once mirrored and once normal
I was too lazy to draw the sprite 2 times

Both Programs in combination it looks like this

I like the way you are going with this.
I knew some guys in the 80's doing it for zxspectrum.

What fun!

Here's a modification to include a track.
At the very end is a data block that encodes the track. You can change it for any course you might like.

I'm not sure if I have the sky movement correct. I don't have an SD card connected, so I can't load the sky graphic to test.

  stanleyella said  I get errors like

RUN
[100] Blit write #2,132,200,1
Error : Syntax

when usibg blit instead of sprite.
The available commands are:
BLIT READ #b, x, y, w, h
BLIT WRITE #b, x, y, w, h
BLIT LOAD #b, f$, x, y, w, h
BLIT CLOSE #b


In the VGA firmware, you can flip the sprites. This is not available in the TFT version so you will have to create the flipped side of the car as an additional sprite.

A lot more to do to convert to non vga but the road works and I can redo the car as any sprite.. sorry blit.
Nice road code. Lots of maths to learn. I am impressed.
My version of scrolling was slow using blit but that was lcd.
Using blit read blit write was faster than using blit x1,y1,x2,2,w,h

Hi Stanley

  stanleyella said  I get errors like

RUN
[100] Blit write #2,132,200,1
Error : Syntax

when usibg blit instead of sprite.
The available commands are:
BLIT READ #b, x, y, w, h
BLIT WRITE #b, x, y, w, h
BLIT LOAD #b, f$, x, y, w, h
BLIT CLOSE #b

ok, if the Version cannot Flip the Sprite/Blit you can modify the Read procedure and Flip them while creating:

Sub read_Sprites
Local nr%,p%,n%,byt$,m$
'--- Read/Create Sprites
Restore car
 For p%=1 To 31
  Read Byt$:Byt$=expand$(Byt$)
  For n%=1 To Len(Byt$)/2
   m$=Mid$(Byt$,n%,1)
   Pixel n%-1,p%,COL%(Val("&H"+m$))
   Pixel 56-n%,p%,COL%(Val("&H"+m$))
   m$=Mid$(Byt$,Len(Byt$)-(n%-1),1)
   Pixel n%-1,32+p%,COL%(Val("&H"+m$))
   Pixel 56-n%,32+p%,COL%(Val("&H"+m$))
   Next
 Next
Sprite read #1,0,0,56,32:Sprite read #2,0,32,56,32
Pause 5000
End Sub

so you have 2 fullsize Sprites.
with little Changesin the do_car sub

Sub do_car
 If dist% Mod 2 Then
    Sprite write #1,132,200
 Else
    Sprite write #2,132,200
 EndIf

it should do the job  

Cheers
