[Mod] Craft Guide [craft_guide] - Shows crafts for all loade

[Linuxdirk]

there is room if you ditch to chitchat about "Learn to craft..."

Yes, that could be removed completely and without any replacement :) And then there would be enough space to display even a 5×5 grid.

I don’t know if it’s possible, but the 3×3 grid could be displayed centered in the space the large grid would take. It wouldn’t look that bad.

[cornernote]

Thats probably the best idea. The workbench is 5x5 (i dont think there are any 6x6 ones), so it would fit.

[Linuxdirk]

Is it possible to scale the slots? They’re usually displayed large enough to be visible even when scaled down by 50 percent. with this you could even add a 10×10 grid in the space of a 5×5 grid.

[Napiophelios]

The note has value and shouldnt be gotten rid of entirely;
First time users may not know how to get things started.

In BookMarks GUI the usage note dissappears when the first bookmark is created,
Can something like that be done here? Like a temporary instuctions?

[Linuxdirk]

First time users may not know how to get things started.

Well, first-time users could/should/did read this. The text could be extended and usage instructions could be given there for people that are too lazy to click the link leading to the instructions.

Thats funny and true...but just in case..
lets assume they are just too excited to get started to read the instructions
and help them out a little. :)

Hi cornernote,
I made a diff file with a formatted version of my code. It adds a button instead of a unknown item, when a crafting recipe contains a item called "group:xy". Also changes search function a bit and adds switching from first to last page and reverse.
Please copy from below.

It was fixed today.

Thank you for responding. I am working with the Miner59 version for now. It seems to fully address the problem described in my post. I really like this mod. Thanks for your work.

:)

[cornernote]

Hi cornernote,
I made a diff file with a formatted version of my code. It adds a button instead of a unknown item, when a crafting recipe contains a item called "group:xy". Also changes search function a bit and adds switching from first to last page and reverse.
Please copy from below.

Hi Miner59,

That looks much cleaner. Can you do a pull request on guthub? This way you will be tracked as the contributor of this change.

I can do it for you, but it means github will not mark you as a contributor (although I will still add you to the credits section)

Let me know if you need any help with the pull request.

[Miner59]

Hi,

I can do it for you, but it means github will not mark you as a contributor (although I will still add you to the credits section)

I prefer if you will add it on github yourself. It is ok for me if you are marked as contributur and I don't need to sign in on github.

The diff still has lots of copy & paste code in on_recieve_fields function, but I found no solution to make a for loop out of it.
The problem is that you need to check every button, so it goes: if fields.button1 then, if fields.button2 then, etc...
I tried to use fields.button[1], but this seems not to work. And I don't think you can turn a string in a field name.
So I think only solution is copy& paste how I did...

[cornernote]

Can you post the whole file instead of the diff? That will be easier for me to apply.

Thanks.

If you find it useful then I ask not for your wealth, but simply to spare your time to consider the world we share by watching Earthlings, a multi-award winning film available to watch online for free.

I did and it will take some time for me to process. I asked by ingame partner to watch it, but she said it is too intense for her.

[Miner59]

Hi,
good news, I'm finished with formatting my code and giving variables better names. xD
I tested my changes and finally don't find any problems with it.

I added a few new buttons and made changes, so you can add items to bookmarks now even if you are looking at the "you need:" list.
And it's possible to show a "you need" list for bookmarks now, because you can replace main inventory list with it if you use the small button pointing upwards.

So I'm quite happy with my modifications, maybe the only thing it would need to be a perfect guide would be if it knows recipes for machines from technic mod, like grinding for example.

Here's another screenshot:



Notice that the numbers of items needed are a bit off when the recipes got to complex, like in the example of a HV Battery Box. This are rounding errors which sum up a bit.

Excellent work!

Notice that the numbers of items needed are a bit off when the recipes got to complex, like in the example of a HV Battery Box. This are rounding errors which sum up a bit.

Can you give a brief explanation about how it calculated 15.11 of an item?

You should run math.ceil on the number, just so it doesn't have a decimal.

I don't mind being challenged with difficult material, but I don't pretend to have all the answers.

Notice that the numbers of items needed are a bit off when the recipes got to complex, […]. This are rounding errors which sum up a bit.

Then don’t round while calculating and only round as last step right before displaying? :)

[Miner59]

Can you give a brief explanation about how it calculated 15.11 of an item?

You should run math.ceil on the number, just so it doesn't have a decimal.

You actually need 14 raw latex, so it's 1,11 off.
The explanation is, that all items of the recipe are added to inventory slots first, then they are counted.
If there are too many items they wouldn't fit inside the inventory.., so I divide them by 50 if numbers get to big.
So I get rounding errors when restoring them later. That's why I said this is a bit hacky...
And you can't just round everything to integers, because if you need a cable and you get 6 cables from 3 copper you only need 0,5 copper in the end.

But I wrote a new version which saves the items in a table, and now it should always calculate correct amount of items. Although I finally found a way to make a for loop which checks if any of the buttons is pressed and this makes huge amount of copy&paste code unnecessary.
I saw that I had added a small image in my texture folder, which isn't needed. I forgot it was there, so you can remove it again.

Here's a diff. I hope it is enough, otherwise i will post whole file again.

Hi Miner59,

It would be a lot easier if you sign up to github. It's really easy to create pull requests. Much easier than making zipballs and much easier than me applying diffs then committing.

Hi cornernote,
finally I made my pull request.
I added support for recipes for the machines from technic mod now.

Is it ok that I made one pull request with all my changes?
I can split if you want but I think this only make problems and much work.
Maybe I will test myself a bit more over christmas, and then you can make a new version of craft guide with my changes. Would be my suggestion...

Ok, I don't want to waste more time with minetest today, Happy Christmas and bye.

Ok, cornernote merged my changes in craft guide now.

I think I write a summary what is new:

- imagebuttons for items which represent a group of items in craft recipes instead of "unknown item"

- "you need" list, shows a summary of all items needed to craft an item. Should always return exact numbers now.
You can switch between "you need" and bookmarks" with " >> " button. "^"-button moves "you need" list up, and it
replaces the main list where you can select the item from. Please test yourself ingame.

- now you can switch directly from last page to first page and reverse

- it shows now when you can use an item as fuel and shows the burntime. Items with no other craft recipe other then
the one of type "fuel" aren't shown. (because this would include things like tree trunks or saplings)

- it shows the registered craft recipes for Grinder, Compressor, Extractor, Alloy Furnace and Centrifuge from technic mod


And a tip for searching a special item:
The items in the main list are sorted alphabetically, including the prefix. So items of one mod are usually together because they have the same prefix. So you should better be able to find a special item
Also there is a search function, you can use this if you know how the item is called which you search.
If you know that the item is in a group, you can search for "group:wood", or other groups like "group:soil" or "group:cracky".
Additionally if you enter "*" in search field it shows items without craft recipe, too.
