Value to multiple sprites through the same parameter

Question

I'm going to ask the same question "
"contains" doubt in hexadecimal color value?" but in a
different way, because I figured out that the solution is simpler
that I thought, and the solutions goes by other way. I have this
behavior:
property pTargetSprite, pBlendValue
on getPropertyDescriptionList me
list = [:]
addProp list, #pTargetSprite, [#comment: "Target Sprite:",\
#format: #integer, #default: VOID]
addProp list, #pBlendValue, [#comment: "Blend Value:",\
#format: #integer, #default: 100]
return list
end
on mouseDown me
sprite(pTargetSprite).blend = pBlendValue
end
I would like to enter MULTIPLE sprites for 1 parameter, that
is to say when the dialog box of the behavior appears and ask me
the "Target Sprite:", I would like to input ...let's say 1 , 2 , 3
, ... whatever numbers I want. Therefore, the blend values of that
sprites will change according to the input Blend Value. Right Now
is working perfect, but of course with only ONE sprite, but I want
to be able to assign that Blend Value to multiple sprites over the
same parameter.
I guess it must be very simple, but I cannot get the answer
anywhere in my brain, nor my director book, nor in the forums.
Thanks!!!

Answer 1

You have several options here. You can do as you suggest,
create a list
of the sprite numbers to change and then tell each of those
sprite's
blend value to change.
Another method is to write a function in the behavior that
you attach to
each sprite and then use sendAllSprites() to fire each of
those
functions. If you are attaching behaviors to each sprite this
may be the
way to go.
For method 1, you could amend your behavior like this:
property spriteList
property blendValue
on getPropertyDescriptionlist
myPropList = [:]
myPropList.addProp(#spriteList,[#comment:"enter the sprite
channel
numbers to use, separated by
commas:",#format:#integer,#default:"1,2,3"])
myPropList.addProp(#blendValue, [#comment: "Blend Value:",\
#format: #integer, #default: 100])
return myPropList
end
on beginSprite me
spriteList = stringToList(spriteList)
end
on stringToList(thisString)
oldDelim = the itemDelimiter
the itemDelimiter = ","
thisManyItems = thisString.item.count
tempList = []
repeat with n = 1 to thisManyItems
tempList.add(thisString.item[n])
end repeat
the itemDelimiter = oldDelim
return tempList
end
on mouseUp me
thisMany = spriteList.count
repeat with n = 1 to thisMany
sprite(n).blend = blendValue
end repeat
end
for method 2 you could use something like this in each
sprite's behavior:
property blendValue
property thisSprite
on getPropertyDescriptionlist
myPropList = [:]
myPropList.addProp(#blendValue, [#comment: "Blend Value:",\
#format: #integer, #default: 100])
return myPropList
end
on beginSprite me
thisSprite = me.spriteNum
end
on changeValue me
sprite(thisSprite).blend = blendValue
end
and then you can call this second method from a mouse event:
on mouseUp me
sendAllSprites(#changeValue)
end
and every sprite that contains that function in the frame
where it is
called will execute.
