LiveCode Forums.

Hi there,
I am trying to animate a button like a person blinking.
I have 2 images and from the script of animating enemy space ship, I was able to make mine work.
Problem: When I go to next/previous card ( 2, 3, etc), it shows error because the runAnim cannot find the button or image to replace (they are in card 1).
Can it be fixed, or a code to stop the runAnim3 running or a better way.
NOTE: Every card will have up to 4 of this individual animations.
Thanks

Here is the script:
-----------------------
on preOpenStack
set icon of button ID 1175 to ID of img ID 1177
end preOpenStack

Local blinkAnim

on openCard
if blinkAnim = "" then runAnim3
end openCard

on runAnim3
if blinkAnim = 11 or blinkAnim >11 then put 1 into blinkAnim
if blinkAnim < 10 then
set icon of button ID 1175 to ID of img ID 1177
add 1 to blinkAnim
send "runAnim3" to me in random(10)*100 millisecs
else
set icon of button ID 1175 to ID of img ID 1178
add 1 to blinkAnim
send "runAnim3" to me in 250 millisecs
end if
end runAnim3
-------------------------

You need to cancel the pending message.

see the pendingMessages() function, as well as the cancel command.

Hi Mission007,

at first, welcome to the forum

Yep, Björnke is right.

However here some useful hints:
1. you should give your buttons meaningful names instead of "button id XYZ"
2. You should add a descriptor, so the objects will ALWAYS be found:
... of btn "xyz" OF CD 1
## of stack XYZ ## if neccessary
3. the ID of image ID 1077 is: TADA -> 1077
So you can save some typing AND if you ONLY use the ID, LiveCode will find the image
and will NOT give you any error in this regard!

So try this: Best

Hi, Thanks Björnke and Klaus
Thanks for the quick response and thanks Klaus for humorously correcting me.
( I liked "El Blinko)

I made the command stop using:
-----
on mouseUp
      repeat for each line aLine in the pendingMessages
            if aLine contains "runAnim3"  then
                  cancel item 1 of aLine
            end if
      end repeat
go to next card
end mouseUp

I had to copy from someone because I didn't know how to use it. (some commands are intuitive, others for professionals...)

My problem is that when I go back to that card, the animation don't work any more.
Is there a way to have simple independent animations, this way I can place several in one card, go to next card and go back to same and they still animate?
Also place other animation on different cards. (basically it is a storybook where you go from page to page read and see animations. Nothing too fancy)
(If you didn't figure out, I am a newbe...)

Hi Ed,

since you completely stopped the animation, can't you just start the animation (again) when you go to a card like this: ?
