Puzzlers - you can use the "Hide" tag

We have a "Hide" tag, which lets you enter your answer but people have to click on a button to see it. This lets other people have a go without seeing your answer. It doesn't really hide it, but does remove it by one click.

You use it like this (use [] not {} ):

My answer {hide=is this}42 !{/hide}

Re: Puzzlers - you can use the "Hide" tag

Not a bug ... just lack of a feature smile

I  have not BBCode'd it ... I just went for straight text.

But I can put that on my list of features to add if you like ...

Quite right, but not as simple as one would imagine. However I am close to a solution.

So, if all hide tags suddenly look silly - that'll be me!

Re: Puzzlers - you can use the "Hide" tag

OK, you can now use bbcode in "hide" tags - please tell me how you get on.

(But don't use bbcode on the button text, I can't get that to work because of html limitations, hence the smiley on this button isn't rendered, but it works on the message page smile )

Re: Puzzlers - you can use the "Hide" tag

Now that all the buttons work, mathsy's signature button doesn't seem to be...

It displays the tags and all the writing instead.

Re: Puzzlers - you can use the "Hide" tag

Why do all the posts with hide tags in them have things like this

Mathsyperson   justlooking      kylekatarn      MathsIsFun
(495==641)     (495==495)    (495==895)     (495==2)

above them?

We all seem to have our own special number! Have they always been there or is it a new improvement...? smile

Re: Puzzlers - you can use the "Hide" tag

The shortest tongue twister is actually 'sixish'. It only works if you trying saying it lots of times though. Plus, it's probably not a real word. At least it's very short.

Re: Puzzlers - you can use the "Hide" tag

I was messing around with some BBCode and found this (highlight the post):

A new way to hide stuff!
Of course, that only works if you assume that everyone uses SleekBlue, but still, it makes a change from hide tags.

Re: Puzzlers - you can use the "Hide" tag

I didn't believe you till I tried it, and you're right, it doesn't work in different styles.  It's a fairly simple task to get the style the person is viewing, then change the font to the background color of the post.  Weird.

I think I'm using oxygen. The text is almost the right colour, and blends in especially well if I tilt my screen down.

Re: Puzzlers - you can use the "Hide" tag

And I actually looked at doing that when I developed the original hide tag.

It *may* be possible to match the user's style color, but that is in a stylesheet, so not available automatically (I would have to hard-code the colors, making upgrades complicated)

Why I use a separate page for the hide tag is so that I can (in a future upgrade) actually block them until the puzzlemaster allows.

Re: Puzzlers - you can use the "Hide" tag

I can't block it yet!

Only because I haven't figured out a good "trigger" for blocking or not.

I thought that the original author of the topic could include a keyword in the title, such as "Open Puzzle" or " - Current", and that would let my software know to disable all hide tags for that topic.

Suggestions welcome.
