How do I make a backspace button for a keyboard?

I’m making a keyboard in Creative.


Each letter involves text, and a button, which is connected to a trigger that has the following block (different for each letter):

There is a game overlay that updates to the Property Text.

There is also a clear message button which sets the text to ’ '.

Is there a way that I can make it backspace a single letter without having to clear the whole message?

I’m not totally sure, but I don’t think there’s a way within the current block coding system.

Yeah, unless you can somehow assign like a variable or number to each letter typed, but I don’t think that’s possible with the code blocks in gimkit.

If you set the code up so that the current text to a property, let’s call it TextOneKeyPressAgo, and then the letter gets added onto the current line, you can make a rudimentary backspace key. When the key is pressed, set the text to the TextOneKeyPressAgo property.

Hmmm, this only works with one backspace, which isn’t practical. Expanding this system would take up a lot of memory, I wonder if there’s a better solution?

I was thinking about having each key stored as a property, but the main issue is you can’t unjoin things you already joined

You know, there’s a lot of cool computer science stuff that does some impossible stuff within limits. For example, there is a way to write packets of data in such a way that if the packet is damaged and is corrupted, it can fix itself, even when the anti-corruption is corrupted. What I’m getting at here is that there might be a way to write text as a number, where we could then do math operations on it to remove previously existed text.

Yes, but how would we tell Gimkit to do the correct operations?

Hmm. I have an idea, give me a second to type it.

Let’s have a number property. This will store our text. Every two digits will represent a letter in number code, ex: 0805121215. Then, when we want to subtract a letter, we just remove it as a number. So for the above example, we would do -15. Then we would do -1200, then -120000, adding two zeros to what we subtract each time. If we want to add a letter, first check for sets of 00s, and add the appropriate number. If we have a number with no 00s at the end, we can multiply by 100 and add the letter we want in number code.

They store a string as a list of 8 bit numbers, and when backspace is pressed, they remove the most recent entry into the list.

The way they write characters in 8 bits is called ASCII, if you want to learn more about it.

Okay, that’s a plan. How would we store the reverse operations?

Also, when I manage to get un-stuck from the airport I’m in and get home, I’m gonna write a tutorial on this, so don’t beat me too it please :smiley:

There’s only one problem, we need to know the most recent character to delete it. We also need the length of the string.
