Hi,
First I love the games. So far I have only been trying the free games. I am trying to use it in my chemistry class and with that I would require subscripts and superscripts to input chemical formula. I tried using html code to get this to work but no luck.

I have been using "hot potatoes" to do my online activities. I recently discovered contentgenerator and prefer your games, and quiz. They seem to have more 'zing' and would be more enjoyable to play, but without subscripts I am going to have to stay with "hot potatoes". "Hot Potatoes is a great set of programs, but variety is the spice of life.

Keep up the good work.

Thanks for the positive comments! I also fully agree about Hot Potatoes - it is an excellent suite of programs and one that I use. The ContentGenerator.net programs have never been designed to replace or compete with these, but rather complement and extend assessment into a more entertaining and engaging way.

Could you possibly give some examples of the kind of thing that you need to input. Due to the nature of the exercises, namely that they use Flash rather than JavaScript, it is much trickier to include equations. However, you can input the full series of unicode characters as shown on the site below. Hold down the ALT key and press the relevant number:

I suspect what you need is the ability to enter any text as super or sub script, which currently isn't supported due to the complexity and nature of rich-text formatting in Flash. If there is a specific font that includes Chemical symbols it might be possible to embed that into the finished applications.

Just checking up on the Adobe site about this too - came across this :)

You cannot enter subscript or superscript text in dynamic and input text fields in Macromedia Flash 8. However, you can use these in static text fields.

Similarly, using subscript and superscript in a static text field that has been set to selectable will fail. Entering subscript and superscript text in a static text field, then enabling the selectable option, will cause the subscript and superscript text to disappear in the final Macromedia Flash Player movie (SWF).


In short, formatting in super and subscript will not currently work due to the way questions are entered and handled in my applications.

However, the excellent QuestionWriter software from Alexander McCabe might be able to help you. His quiz software allows you to change the formatting directly and thus supports superscript and subscript effectively. See http://www.questionwriterblog.com/archives...perscripts.html and http://www.centralquestion.com/archives/20...uperscript.html or the main software at: http://www.questionwriter.com/

There are also ALT codes to place a 1,2 or 3 in the top right hand corner of the character space - doesn't seem to be one for 4 or above unfortunately. I know the small number should be below the line but it is a usable workaround.

HO for example


HSO4 is obviously not possible!!

Hope this helps in some small way.

Thanks for all of your research into solving the problem of subscripts and superscripts. One of the uses I was thinking of was with the half min game. I could have H2SO4 as the clue and the game player would have to unscramble the chemical name sulfuric acid.
Thanks and I praise you again for a wonderful product.

Whilst searching for advice on super and subscripts I cane across you forum. I have sorted out how to do it!
try this link
http://www.palomar.e...tpotquizzes.htm
[Up arrow] (or + on the NumPad) for Superscript
[Down arrow] (or - on the NumPad) for Subscript
Then make sure the text you want to super or subscript is between the sets of cursers;

:wacko:
