AMAL as primary code...

Somewhere in the manual it says you can almost program a complete game in AMAL.

I got around to thinking about this, and have attempted to code a "space invaders" engine almost purely in AMAL and I must say that although it is a pain to keep track of things, and timing considerations are a headache, the results so far are quite fast and accurate.

Has anyone else tried such a project, and if so did you have much success?

see attached file (probably best with A1200 + Fastram)

It's a start, but could surely be improved ..

The game loop is...

Do
Synchro
Wait VBL
Loop

that's it!

Maybe Amiten
Brian bell did Seamore toy capers and got a lot of large Bobs on screen - I think he used alot of Amal
my experience you can get lots of large bobs on screen but is slower on 68000 with average size bobs.
For space invaders you could maybe just use paste bob would be fast but don't know how smooth.

The point of my "space invaders engine" wasn't to make a game, but to see if it works in (as far as possible) AMAL only.

Because it's quick and quite friendly (at least more so than machine code, even with the headache of interaction)

I thought it was a question it's obviously possible as it says so in the Manual and Amiten always uses it but if you want to do something interesting make it using Paste Bob.

Congratulations that start in your space invaders is very good, it moves very well and also you have managed to break the barrier of the 16 objects by Amal deactivating the interruptions, I agree with you that if you deactivate the interruptions in amal it is a nightmare to carry the control of the timmings because Amal what is good is just that to move everything perfectly and in synchrony when the interruptions are activated with the handycap of limit to 16 objects at same time.

Here is an example of our space invaders that is a mix of Amal and Objets by Amos basic, good as a concept is not bad I think , although I like your gameplay more than ours, it would be great to make a mix of your invaders and mine, exchanging graphics , music and the codes just in case.

greetings and to continue with good work

Wouldn't it have been much better if you could do.........

Synchro (channel)?

or even Synchro (c1 To c2)


However that's not an option

Still a work in progress, and if anyone is interested, I'll post updates when I have something more to show.

Thanks for looking

Good stuff there Amiten

and very interesting.

My Idea was to make a full screen invaders engine (something like the arcade format).

Obviously using AMOS there would have to be some compromise, but I tried to be as faithful as possible to my memory of the game.

Here is a Prototype I made using a mix of BASIC & AMAL (with a few 8 bit "jokes" thrown in to keep it fun)...
It only plays once but shows what can be done, and what still needs to be done...

Updating & interfacing the AMAL more is top of my list to speed this up ....

thus my original post.

A1200 +Fastram required!

A1200 +Fastram required of course.
