Re: Linux port of reconstruction, now in C/C++

I think that arbitrary code execution should not be emulated; it should probably check for such things and display an error message in most such cases. This is also true for some cases of arbitrary memory accesses, but some cases of out of bounds memory accesses should be emulated, either by providi...

Check for dark places

It is possible to use a ZZT-OOP code to check for if a place is dark. The draw procedure for stars will change their colours, so you can check if something is visible (either because the room is not dark, or because it is in the range of the torch light), by throwing a star and then to change into s...

Re: Another external editor: frezed

Can there enough for a Windows port of this after you are finished developing it? I do not have linux. I will not (I have no way to test it), although it is possible that someone else will be able to port it to Windows; I may accept such patches though. If I do not accept the patches for whatever r...

Another external editor: frezed

The external editor being made to use with FreeZZT is called "frezed", and this external editor is for Linux rather than DOS. Many features are like ZZTQED (including numeric prefixes, mass mode, boardwalk mode, etc), although it is much faster (it loads (seemingly) instantly on my computer), and th...

Re: zima - ZZT image converter

I think that perhaps a command-line mode should be added too.

Re: Game of XYZABCDE - Part I

Note that the part near the end of the introduction in the game about Free ZZT was written before Free ZZT was written, so it is not fully applicable now. However, XYZABCDE.ZZT remains public domain, and it works with FreeZZT as well as the official ZZT executable file. If you want to cheat at it, y...

Re: player turned into lion by conveyor

Sadly, despite being easy to reproduce by hand, it doesn't seem very exploitable. Swapping stats sounds pretty great, but you can only swap stats with stat elements that can be conveyed, which doesn't include objects (where changing code might be powerful) or passages (where changing destinations m...

Re: The Reconstruction of ZZT

A note to those making/maintaining external editors for ZZT: My own FreeZZT has a /P switch, which causes it to skip the title screen, both when starting and when exiting ZZT. (The standard ZZT ignores this switch.) This may be useful for the test function in external editors.

Re: Linux port of reconstruction-of-zzt

(for instance, the Museum of ZZT Discord recently found a way to transfer data across loaded worlds by using a bug to destroy board edges around the loaded board, which are not cleared by merely reloading worlds) Is this something using conveyors? I have found a way to do what you described much in...

Re: Zeta - a different approach to modern-day ZZT

Are you going to implement EMS in Zeta, now that some forks of ZZT (such as OpenZoo and FreeZZT) can now use EMS?

Re: The Reconstruction of ZZT

I made a Fossil repository with my changes to ZZT at: http://zzo38computer.org/fossil/freezzt.ui It is not yet complete, although it does work, and you may include some of my patches in OpenZoo if you want to. (Not all of the changes are in the timeline (sorry), because I did not set up the Fossil r...

Thank you for this; I will use some of these patches. Once I release my code, you may put some (or all) of my patches in there too if you want to. I will post a link once I make it available.

Re: The Reconstruction of ZZT

I have downloaded it and have removed many unneeded things (including the editor), reducing memory requirements by more than 10K. I have also added a ?-KEYS command to get rid of all keys, and ?FLAGS to display flags, and fixed a few bugs (some will remain for compatibility purposes), and a few othe...

Re: The Reconstruction of ZZT

This is good, and can be helpful for many purposes (including: seeing its working, fixing some bugs (although some you probably want to keep for compatibility purpose), removing unused stuff in order to make more free memory, fixing documentation, etc). I also posted a message on my NNTP server (whi...

zztff (make a screenshot of ZZT world or save game)

I wrote my own program to make a screenshot of a ZZT game (without needing ZZT). Although Dr.Dos's program was written before mine, I was unaware of it at the time I wrote mine. You can find documentation at: http://zzo38computer.org/fossil/farbfel ... name=ffzzt This software is public domain.
