How to discard most default actions and rules?

I am writing a small game and I dont need most of the default actions.

I created an awkward :
instead of the player doing something other than…
and a:
Rule for printing a parser error

to block all commands except a few.

But for example if the player types “attack”
there is the default rule that provides a missing noun that displays “(Charles)” if for example a person called Charles is here, before writing the expected error message.

How can I disable all these kind of problems I can’t even imagine since I don’t know all the default rules and actions?

Below is code for making Inform forget all player’s command verbs defined by the Standard Rules. Edit to suit your purpose.

[rant]Understand the commands “take”, “carry”, “hold”, “get” and “pick” as something new.
Understand the command “stand” as something new.
Understand the commands “remove”, “shed”, “doff”, “wear” and “don” as something new.

Understand the commands “give”, “pay”, “offer”, “feed”, “show”, “present” and “display” as something new.

Understand the commands “rub”, “shine”, “polish”, “sweep”, “clean”, “dust”, “wipe”, and “scrub” as something new.
Understand the commands “tie”, “attach” and “fasten” as something new.
Understand the commands “burn” and “light” as something new.
Understand the commands “drink”, “swallow” and “sip” as something new.
Understand the commands “cut”, “slice”, “prune” and “chop” as something new.

[Understand the commands “score”, “quit”, “q”, “save”, “restart” and “restore” as something new.
Understand the commands “verify” and “version” as something new.
Understand the commands “script” and “transcript” as something new.
Understand the commands “superbrief”, “short”, “verbose”, “long”, “brief” and “normal” as something new.

Understand the command “notify” as something new.][/rant]

(This approach won’t result in a notably smaller game file however. All the actions etc. will still be defined as usual, only the player can’t trigger them. So, its usefulness depends on why you want to disable standard actions.)

There is no simple solution ? incredible!
Anyway thank you it will be useful. I will delete just the few I need the parser to answer to ^^

It’s looking more and more like I7 may not be the right language for your project.

There has been talk of writing a “Standard Rules Lite” extension. I did some poking around to see if I could delete all actions at a low level, but there appear to be complications.

I could have sworn someone else has already started work on the project though. Was it Ron Newcomb?

I’m pretty sure that “Default Messages” (which I love) will let you define a custom default response.

This is a simple but brutal solution, which basically throws out the whole parser and then puts a few bits back in:

[code]Section Grammar (in place of Section SR4/10 - Grammar in Standard Rules by Graham Nelson)

[by Juhana Leitonen]

Understand “quit” or “q” as quitting the game.
Understand “save” as saving the game.
Understand “restart” as restarting the game.
Understand “restore” as restoring the game.
Understand “verify” as verifying the story file.
Understand “version” as requesting the story file version.
Understand “script” or “script on” or “transcript” or “transcript on” as switching the story
transcript on.
Understand “script off” or “transcript off” as switching the story transcript off.[/code]

Simply writing a section that goes in place of SR4/10 eliminates the part of the Standard Rules that contains all the declarations; the actual section puts back some of the metacommands that your players are going to want. (Especially quitting. Don’t remove quitting.) Then you’d have to declare all the commands that you want to work – in the games Juhana and I used this in, we were processing commands entirely through keywords.

Even with this section put in, the game will still understand a direction as going in that direction (so “w” would be understood as going west). I think that’s hardcoded into I6.

I tried ripping out the whole of Part SR4, which includes not only the grammar section but all the action definitions and specific action processing rules. That didn’t go so well - most of the actions are built into I6, below even the template layer.

But your idea makes me think I can at least do a little better. Here I copied Part SR4 and edited out all the specific action processing rules except for the out-of-world ones. Then I used your grammar section:

Depending on what you’re doing, you might want to put back the rules and specifications for a couple actions, for example looking, going and taking, which can be triggered by low-level events.

If there’s not already an extension to do this, what do you think about me or Matt or Juhana submitting this modification as an extension?

Yes please! :slight_smile:

Okay, that’s a nice vote of confidence!

What do you think about keeping at least some of the rules for looking, taking, and going? (probably just the ones that interact with each other)

I think I’m remembering what Ron Newcomb did. It was even more drastic - I think he may have even removed most of I6 from the story. I’ll go look for his post…

Here it is:

https://intfiction.org/t/compilation-efficiency/3102/12

It seems like there are several layers which you might want to strip away:

  • Commands which do nothing: rubbing, turning, jumping etc.
  • All commands except those which have a direct effect on the world model: so this also tosses out waiting, listening, asking etc.
  • All commands except for some very basic subset, as you suggest… although I’m not sure whether there could be an agreed-upon subset that would be useful to people. LOOK, TAKE, DROP, GO? (edit: oh yeah, and that EXAMINE thing.)
  • All commands except meta-commands like UNDO etc.
  • Every single command.

Ideally you could offer use options that would let an extension user just pick what they wanted, but until/unless conditional compilation is added to Inform, this isn’t possible.

The most-requested variants of this, it seems to me, are the first and maybe the fourth. Either one would probably find an appreciative audience.

It looks like even Ron’s version doesn’t remove the underlying I6 actions. But they don’t take up so much space, I suppose.

I think the bedrock version of an extension like this needs to strip out everything except the parser-implemented metacommands (OOPS and UNDO), which are not listed in the Standard Rules. It’s easier to paste things back in than it is to remove more things from an already replaced section.

You could then have a couple of pasteable code blocks in the extension docs that users can include to selectively restore some of the layers that Aaron mentioned. Conditional compilation would, as Aaron mentioned, be much nicer–but basic, non-sexy functionality like this has not tended to perform well in the Uservoice rankings. I don’t know how important the votes are when Graham et al make decisions, but if they use votes to prioritize, conditional compilation isn’t happening anytime soon.

–Erik

The actions are gone from the compiled game – along with most everything else that doesn’t explicitly appear in the source – but the Naga project isn’t suitable for being an extension because it breaks so much of I7.

If you’re wanting to remove actions wholly (not just the player’s references as done up-thread), then after doing said replacement, use the template replacement functionality mentioned in 25.25 “The Template Layer” in the manual. Spatchcock stubs as needed.

OTOH, for Michael Bacon’s Interactive Poetry extension (see the Inform site), we just hid the actions, since it was easier than to remove them from the templates and memory.

Did that make sense?

In fact I decided to make a very simple game to learn I7 a bit more and I ended with this problem (lol)
“Very simple” is not so simple to do with inform7 as well :wink:

Ooh this looks nice.
It seems I can add the few actions I need as well.
Thanks a lot!

Yes thank you very much, I in fact need the opening action.
I also use a talking action and an examining action (maybe) as well.
The game is mostly a talk thing… and there is only one room. And it is more a story than a game.

Second vote on the love. Love love love. I think if I had to pick just one extension to bring to a desert island, my brain would explode deciding between that one and Plurality.

I knew there was something like that already! I looked at the site, but as usual, their system of organization doesn’t lead me to anything.

I’ll have a look at Interactive Poetry and think about submitting something complementary, or creating an update.

I guess I should look into it ^^

It seems like the best solution would be restructuring the Standard Rules into more detailed subsections; then we could create new sections “in place of” those to remove specific actions or groups and leave the rest.

For example, if Part SR4 - Actions became a Volume and Section SR4/8 - Standard actions which always do nothing unless rules intervene became a Part then we could assign each action its own Section, such as:

[spoiler]Section SR4/8/- Rub

Rubbing is an action applying to one thing.
The Rubbing action translates into I6 as “Rub”.

The specification of the rubbing action is
“The Standard Rules define this action in only a minimal way, blocking it
with a check rule which stops it in all cases. It exists so that before
or instead rules can be written to make it do interesting things in special
cases. (Or to reconstruct the action as something more substantial, unlist
the block rule and supply carry out and report rules, together perhaps
with some further check rules.)”

Check an actor rubbing (this is the block rubbing rule):
stop the action with library message rubbing action number 1 for the noun.[/spoiler]
… and a corresponding section in Grammar

[spoiler]Section SR4/10/- Rub

Understand “rub [something]” as rubbing.
Understand the commands “shine”, “polish”, “sweep”, “clean”, “dust”, “wipe” and “scrub” as “rub”.[/spoiler]
The Grammar section could then be broken up into equivalent Parts as the action definitions, so they can be removed categorically as well.
