Please help. I'm new to Rev
I want my script to display random text on my stack! There are graphics on it. It looks like a couple of buttons: when pressing the right one, it tells some random message, when pressing the wrong one, it tells another random message.

I know how to display a random javascript message, but this is not an HTML.

So the question is:
how to make that random text messages display on a graphic (a png image).
I do not want to use the "answer" command, because it brings another window!

Thanks beforehand

Rather than a graphic or image, why not use a field control?

Code: Select all

put "Hello, world!" into field "MyRandomMessage"
show field "MyRandomMessage"

If you want to add some styling information, you can also use the field control's built-in htmlText property

Code: Select all

put "<p><b>Hello, <i>world</i>!</b></p>" into theHtmlText
set the htmlText of field "MyRandomMessage" to theHtmlText
show field "MyRandomMessage"

Dear Ledragon,

Create a transparent field on top of the image object. Keep your collection of sentences somewhere in a field or in a custom property. Let's assume you use a field in this case. Then use the following script in your button:

Code: Select all

on mouseUp
  put any line of fld "Collection" into fld "Transparent Field"
end mouseUp

That's it.

Best,

Mark

Thanks a lot! I did non imagine it would be so easy!

However, my text is in Armenian, and on input, it changes the characters.

In other words, there is a font problem. I suppose it may bring problems on deployment on different operating systems as well.
So I need to declare a font I suppose and somehow put that font into the application.
Is it possible? Or how can I handle this in other way?

Hi Ledragon,

You *might* try the following:

Code: Select all

on mouseUp
  put any line of the unicodeText of fld "Collection" into myUnicode
  set the unicodeText of fld "Transparent Field" to myUnicode
end mouseUp

This is just a guess, though. Does this work for you?

Best,

Mark

Edit: I added a NULL at the end of the line, but this is not necessary.

Thanks Mark!
I found out that this is an Armenian font problem. Some are unicode compatible but there can be problems on viewing them in different OS.
Instead I decided to convert all my text to images, collect those text-images into a separate substack and call a random one on click!

So, thank you very much for your efforts to help me.

Dear Mark,

Thank you for useful tips.

However, I'm still stack with my script.
I want a random image (which is a text converted to image) of stack x to be shown on stack y on click
and there is a button which removes that text-image and replaces it with another image (some kind of relaunch button "play again", the principle is hide and show the image).
I made the whole application (it's a game for little children, called in which my hand) but only with 3 possible images, like "play again" (hides the message "you won" and the message "you lost"), the "you won" message hiding the other two messages and so on. So on show of one image the others are hidden.

But now I want to put more winner and looser messages (messages are images). So on winning it displays a random "you won" message and on loosing it displays a random "you lost" message.

I thought that separating these win-and-lost images in different invisible stacks or cards will help. However, I was unable to make the picture of one stack or card show on the main one.

Can you please give a hint?

Hi Ledragon,

You might try the following:

Code: Select all

if theAnswerIsCorrect is true then
  set the icon of btn "The Message" to the short id of any img of stack "Stack with Right Messages"
else
  set the icon of btn "The Message" to the short id of any img of stack "Stack with Wrong Messages"
end if

This script needs a transparent button, called "The Message". You don't need to show and hide images or put images on top of each other. You only need to set the icon of the button. If you don't want to show any message at all, use

Code: Select all

set the icon of btn "The Message" to 0

and if the buttons gets in the way, use the show and hide commands to show or hide it as needed.

Best regards,

Mark

if iwin = 1 then
set the icon of btn "Message" to the short id of any img of stack "Winner"
else
set the icon of btn "Message" to the short id of any img of stack "Looser"
end if

However, when the script is launched, it brings a random image from any image in the project. It does not differentiate between stacks!
When I put the id-s instead of names (like id 1009), it brought an error telling there was no such a stack

Is there some kind of a bug? Or is something wrong with my file?

Hi Ledragon,

This isn't a bug, this is a slightly impractical feature :-) Just change the id of all images in your two stacks. You can even write a script for this.

Code: Select all

repeat with x = 1 to number of images
  set the id of img x to (the id of img x + 10000)
end repeat

Best,

Mark

Mark you are the best! Thank you very much for all. I finally made it. It's great to see that your creation works, whatever it is.

Thank you
