Spectrum Computing

If you want to see how it works, export 6144 bytes from address 59083 while it's running. Then reset the Spectrum and load those bytes back in at address 16384.

Best to watch from some distance. Really. If you are at some desk, wlak away from it

Can anyone unzip this? I'm using 7Zip and it can't handle it.

I couldn't extract it either using 7Zip. Out of interest I also had the same problem with the CSpect Next emulator which is also packaged as a RAR file so some kind of setting may be being applied when these are compressed, as 7Zip normally has no problem opening such files.

In the end I had to use the free command line unRAR utility (https://www.rarlab.com/rar/unrarw32.exe).

Also just found this useful online tool https://extract.me/ which will open it and allow the contents to be downloaded...

Odd, I've managed to open it with 7Zip just fine. Maybe you need to update your software? I'm on version 18.05 (x64, Windows).

Yep, thanks [mention]PROSM[/mention] that was indeed the problem. I was on version 9.0 upgraded now to version 19.0 and it handles these RAR file ok now.

Dear all, here is my second game... Birdy Cantabile (a Musical Puzzle)

If you have Fuse+Spectranet (or a real Spectrum + Spectranet peripheral) you can try the Android TCP/IP Virtual Joystick and play wireless using your Android phone or tablet as a joystick with this version below (instructions to use it are in the first link):

Some screen caps, hope you like it! Cheers!

Excellent! And thanks. This and your first game will be in the next update, sorry it's taking a while.

This looks cute! However, I take issue with random notes being displayed as mirror images. Gotta fix that, man. Gotta fix that.

Hi thanks for your feedback! But sorry I do not understand very well do you mean that for instance the sticks of the musical notes should all be to the right side of the notes so the tiles that have those mirrored notes right now are not real notation? or is another thing?

If you mean that, sure I will fix it for the future 128k version!! Cheers!

I think he's talking about the crotchets (filled notes) in that screenshot, they're facing the wrong way. Only the upward stems are meant to be on the right, the downward ones go on the left. And technically if a note is above the centre line, the stem points downwards, otherwise it points up.

But it doesn't really bother me that much So you can decide whether it's worth changing or not.

Well, sheet music is written (and read) left to right. Notes have heads and stems (aside from whole notes, that is) that are appended to the right of the heads if they go up. For notes that are written with their stems down, you simply rotate them 180 degrees, so the stems end up on the left side.

For deciding when a stem goes up or down, a simple rule is the note B (which is written on the middle line of the staff). It can usually be written with the stem going in either direction. Notes that are below it have their stems go up; notes that are above it have their stems go down.

Dots (which simply extend a note’s duration by half) are also written to the right of the notes.

So, as an example of one of the note groups you have in that screen (a dotted quarter note, followed by a quarter note, followed by a half note), here’s what it should look like:



The same goes for the pictogram in the bottom left.

Thanks for the explanation! I have changed all. If you download the .tap now I think is more realistic Hope you like this one!
Indeed if you refresh this forum page in your navigator the images of our former messages should be changed by the new ones too (the cache sometimes takes one or two navigator refreshes to update the images). Cheers and thanks again!

Excellent! Looks great now.

New verion of game Pariboro.
http://hracka.org/~mike/2019/05/11-pariboro-v11/

Really nice. That background twister is very cool.

A high score feature would make it even better.

Sweet little puzzle. I’d modify the redefine keys routine to exclude duplicates (i.e. the same key being defined for multiple controls).

Feel free to have a look at mine here.

Hi iadvd,

congratulations on your second game, I like it even more than the first!

Although it is not easy to create something "different" with the Churrera - that's why I used it myself very rarely, on Cousin Horace only in fact - the setting and gameplay seem unusual enough to me, and that's a big plus for me.

Not the most polished AGD game but good fun! We'll need a few more like this to warrant a 'Scottish Cryptozoological Theme' group in ZXDB yet though .

If anyone's in touch with the author could they get a 'aye' or 'nay' regarding hosting the game at SC?

Hi guys,
This is Dougie Mcg.

It's an 'aye' from me.

This is actually a project I've been making for my primary 6 class (10 year olds) using only the skills I am teaching them.
We use AGD in class after we've finished the coding part of our curriculum.
I wanted to show them that they have everything they need to go on and create their own speccy games and release them. Hopefully over the next few years as they build their skills we'll see the next batch of great speccy coders coming through. More importantly though they are developing a deep appreciation of the zx Spectrum and the joy of coding for it.

Thanks for hosting the game. It was great fun to make.

Cheers,
Dougie mcg

Make sure you get the version 2 one as I've fixed the penultimate level.

This is fantastic. So how did it work in practise? Did they all have AGD on their own computers and help design levels? What was their input?

There are loads of modern game design tools out there, but I think the joy and simplicity of AGD means it can stand proud among them.

Yep version 2 will be in the next update. Ta for the game, and for giving some hope the Speccy might last longer than us codgers!

The class all have their own computer and run AGD 4.7.
We have a tutorial each week on a certain skill and then build a level around that.
The kids are all completing their own games and are at different stages. Some with 3 levels others with 9 or 10.
They were asking what happens when you finish a game so I published Sc0tb0t to show them.
I've only used skills I have taught in class so they can see exactly what they can make themselves.
They have contributed with a few plot ideas and level design tips but are busy coding their own projects.
We had a visitor input on Scottish mythology so I wanted to show them that you can take any idea and apply it to make a game.
They are very excited about the prospect of finishing their own games in between getting distracted by the zx Spectrum library.
It's fantastic to see my pupils running up to me each day to tell me about how they were playing Head Over Heels or Jetpac last night. It just goes to show that with all the distractions of modern day technology, nothing outshines good old fashioned gameplay.

We will gladly host all their games here when they are ready. Just let us know if we should credit the author name of each title, or just credit them all generically as "Students from SCHOOL NAME at CITY NAME". I assume that's not sensitive information (also names can be abbreviated as needed) and students would certainly love to see their names here, but you may need to check with school and/or parents. I'm looking forward to see these titles
