Play an Image Sequence

[bidgeeman]

Hello.
Can anyone tell me how to play an image sequence in Runrev? I have a series of png files I would like to display as a desktop animation with a transparent background.

EDIT:

I found this code in another thread but cannot get it to work.

Code: Select all

local counterVar 

on mouseUp 
  if the hilite of me then 
    put 0 into counterVar 
    send "animationRun" to me 
  end if 
end mouseUp 

on animationRun 
  add one to counterVar 
  if counterVar >= 5 then 
    put 1 into counterVar 
  end if 
  set the icon of button "animated button" to ("animation" & counterVar) 
  if the hilite of me then 
    send "animationRun" to me in 0.03 seconds 
  end if 
end animationRun 

If someone could look at my stack to see what I have done wrong it would be much appreciated.

Hi Bidge,

I'm not sur this is the best way for animation, but try this

Code: Select all

local counterVar 

on mouseUp 
   set the hilite of the target to not(the hilite of the target)
   if the hilite of  the target then 
      put 0 into counterVar 
      animationRun 1
      -- send "animationRun" to me 
   end if 
end mouseUp 

on animationRun pWait 
   repeat until the optionkey is down --•• 
      if the mouse is down and localloc(the screenmouseloc) is within the rect of btn "button" then
         exit repeat
      end if
      add one to counterVar 
      if counterVar >= 5 then 
         put 1 into counterVar 
      end if 
      put counterVar
      put "ball000" & counterVar&".png" into MyImg
      set the icon of button "animated button" to the id of img  MyImg
      wait pWait milliseconds
      --      if the hilite of me then 
      --         send "animationRun" to me in 0.03 seconds 
      --      end if 
   end repeat
end animationRun 

All the best

Hi jmburnod

Thanks that worked
Is there another way to play an image sequence?

Many thanks
Bidge

[jmburnod]

Yes,

Depend the context but you can

• change the filename of an image
• move an image
• resize an image
• rotate an image
• change de imagedata and alphadata of an image
• change the points of a polygon
• change the blendlevel of an object
• ...

Best regards

Hi Bidge,

I had a look at your stack and here is what I found, but I'm afraid you might not like it!

1. Why do you think that a script that someone posted might immediatley work with your images without any modification?
2. The docs say this about "icon": set the icon of button xyz to {imageID | imageName}
3. The IDs of your images do not fit into this scheme nor do the names of your images
4. The script you posted clearly supposed the names of the images to go from "animation1" to "animation5"
5. Your images are named "balloon0001.png" to "balloon0012.png"
6. The IDs of your images go from 1019 to 1030

So a tiny little bit of thinking would have given you at least a tiny little clue what's wrong, wouldn't it?

Hi Klaus.

I tried renaming the images to "animation 1" etc.....but stll could'nt get it to work. I'm new to coding and trying my best to learn these things....
Thanks for the advice anyways.

Cheers

I decided to go with swapping cards rather than playing the image sequence...this seems to be an easier way for me to achieve an animated image sequence

Cheers

Hi Bidge,

sorry did not want to sound harsh, so please excuse me if I was!

To rename your images was a good idea and you would have succeeded
if you had omitted the SPACE in the new names
-> "animation1" etc. instead of "animation 1"

OR if you would have changed the script to:
...
set the icon of button "animated button" to ("animation" && counterVar)
## Note the double && which will add an extra SPACE
...

You were right Klaus! It was that little space that upset the apple cart
No offence at all taken....I apprectiate all your help here

Thanks for those extra tips too I will try it out again and see how far I can get.

Many thanks again
Cheers

Hi bidge,

try this in the button of your stack:

Code: Select all

local counterVar, myIDs, tRun

on mouseUp
   if tRun then 
      put false into tRun
      exit mouseUp
   end if
   put true into tRun
   put 0 into counterVar 
   put "" into myIDs
   repeat with i = 1 to the number of images
      if the short name of image i contains "ball" then
         put the short id of image i & return after myIDs
      end if
   end repeat
   delete last line of myIDs -- last return
   send "animationRun" to me  
end mouseUp 

on animationRun 
   if the optionkey is down then 
      put false into tRun
      exit animationRun
   end if
   if tRun then
      add one to counterVar 
      if counterVar >= 12 then 
         put 1 into counterVar 
      end if 
      put line counterVar of myIDs into tID
      set the icon of button "animated button" to tID
      if "animationRun" is not in the pendingmessages then
         send "animationRun" to me in 50  milliseconds -- adjust for speed of animation
      end if 
   end if
end animationRun 

to start or stop the animation click on the button. Alternatively you might press the alt key to stop the animation. It checks whether the name of the image contains "ball" and only those images are considered. The way it is now it just looks for the layer of the image (image i ) and does not care about 0001,0002 etc for the sort order of the images.

Hello Bernd.
That works perfectly thanks for your time. Also thanks jmburnod and Klaus too. It appears there are quite a few ways to play an image sequence in Rev.
