How to rotate an object 360 degree?

[Klaus]

Hi Tom,

Hi Klaus.
Would you entertain a few follow-up questions about your stack?

No

1) Being a newbie, I would have written a similar stack using handlers. You used "command". What's the difference? (The LC dictionary doesn't help much on this point.)

A couple of years ago RunRev advised to use COMMAND for custom handlers
and leave the ON for build-in handlers like "mouseup" etc.

If I remember correctly, the reason was that the engine might distinguish this some time in the future.
No idea why, but this has not happened yet, and I got used to it

2) What is the result you are getting back from the "send" message in lin 19 and 20?
I tried to view it as a variable and did not see it. You stored it in tAnimationMessage and used it to cancel
the operation. Is it a message ID?

Yes! When you do a "send", "THE RESULT will return the ID for this message.
You can use that to cancel the next delivery of that message.
Check "send" and "pendingmessages" in the dictionary.

3) You end the animation_stop with "enable btn "animate" of cd 1".
What is the reason for that? (Did the animation process disable the button?)

The button "animate" is rather erm... self-disabling
See line 2 of its script.

Hi all,

Hope you can provide some insight to a newbie.

I have been playing with this script for a while as I have been experimenting with manipulating animations.

What I am playing with at the moment is creating a custom repeat and the best way to approach this with this script.

I would love to see some possible scenarios and your thought processes behind them with comments. Thanks

Hi istech,

what exactly is your question?

Hi Klaus,

Thanks for replying. For example if I wanted to add, repeat 2 times then send cancel Animation message.

Or repeat 6 times then send cancel animation. etc. What is the best solution to add this code? Where is the best place to start.

Kindest Regards,

Tone

Hi Tone,

sorry, forgot my original script, too long ago.
Could you please post my code (again)?

But basically you need to manage a COUNTER and check that everytime.

No worry s it's the one on the first page. I love messing with it. Just learning and tinkering.

half work and half don't but fun learning.

Hi Tone,

AHA!
Yes, I remember faintly

OK, I modified the script to accept one parameter = any integer > 0

Code: Select all

local tAnimationMessage

command mk_animate howoften
  put the icon of btn "wheel" into tCurrentIcon
  
  ## Next icon?
  if tCurrentIcon < 1006 then
    add 1 to tCurrentIcon
    
    ## We already reached the last "FRAME" so we start anew:
  else
    put 1003 into tCurrentIcon
  end if
  
  ## Now set the new icon
  set the icon of btn "wheel" to tCurrentIcon
  
  ## We simply count down to 0 everytime
  ## if howoften = 0, we do NOT send the message again
  ## Otherwise we subtact 1 from howoften and send the message again
  if howoften > 1 then
    subtract 1 from howoften
    send "mk_animate howoften" to me in 100 millisecs
    put the result into tAnimationMessage
  end if
end mk_animate

## This will KILL the appropriate "pending message" and thus stop the animation
command mk_animate_stop
  
  ## Preven setting next icon = stop the animation:
  cancel tAnimationMessage
  enable btn "animate" of cd 1
end mk_animate_stop

In the "animate" button you can now add a parameter = the number of repeats
until the animation automatically stops:

Code: Select all

on mouseUp

  ## Will change the wheel 6 tiems and then stops!
  mk_animate 6
end mouseUp

You get the picture

Thanks Klaus

Given me some more to tinker with thanks.
