Source code help!!

Can anybody help me make a block that looks like this:

(closest sprite)

So that it will report the name of the closest sprite?
I already have the Blockspec, i just need help with the code.
----Help is appreciated---------

Re: Source code help!!

One way to do this with blocks that are already there would be to put all the sprites names in a list and have it run through it to find the closest one using the distance to [ ] block. Sorry I can't help you with making it a real block.

That would work, but how can i make it so that it will do it for all sprites?

True. If I were you i'd use squeak for it.
Something along the lines of:

sprites do: [:sp|(self distanceTo: sp < lastDist) ifTrue: [lastDist _ self distanceTo: sp. closestSprite _ sp].
^ clostestSprite.

Re: Source code help!!

IDEA!!!
i already have a (sprite name) block, so in every sprite, i'll just put:

|WhenFlagClicked|
If <"name's" contains (sprite name)>
add (sprite name) to "name's"
End

then i'll add the distances to a list, sort it out, then find the name of the lowest one.

Thanks Markyparky56!!

LS97, it's telling me that the "sprites" at the beginning is an unknown var. is there another way to make all the sprites perform

Code:

:sp|(self distanceTo: sp < lastDist) ifTrue: [lastDist _ self distanceTo: sp. closestSprite _ sp].

??????????????

Re: Source code help!!

Code:

getClosestSprite
    | minSprite minDistance |
    minDistance _ 1000.
    ScratchSpriteMorph
        allInstancesDo: [:sprite | sprite = self
                ifFalse: [(self distanceTo: sprite objName)
                        < minDistance
                        ifTrue: 
                            [minDistance _ self distanceTo: sprite objName.
                            minSprite _ sprite objName]]].
    ^ minSprite

    ^ minSprite

Thanks. i see how to make all the other sprites do that now.
