Another picking thread

Ok I have an image, and I have set up 5 image points numbered 1-5, and I want to take 5 duplicates of the same sprite and place them on the image with the 5 image points.

Geez we really need a better way to pick from multiple instances, at least we do if you want the idiot savants like me to be able to use this thing.

Any way this:

System: 3 For each spot 0  ordered by spot 1 .x Ascending

Give the sprite a private variable and number them 1 through 5.

Or use magic pink.

Is there a better way than the way I was using?

I thought the for each would work like a loop, and each picked by object's x, would add 1 to private variable "var", then I could use the variable to set to the points. Evidently its not even using the variable when placing the image to the points.

Does it work if you do:

+ For Each Spot

-> Set spot position to Sprite.ImagePointX(LoopIndex), Sprite.ImagePointY(LoopIndex)

Sorry nope.

The loops running fine, but it keeps putting everything on one spot. Initially I thought it was using the original "point", but now it seems its using the hot spot instead.

Anyway I figured a work around, I had each sprite spawn a text with the object unique id, then I just wrote down that info, and made an event for each unique id... works fine.

Now my next question, is there a way to get objects unique id without having to a get them at runtime?

Or use magic pink.

No, seriously... it works. Give the sprite a variable, and number them 1 - 5. You don't need to use UID. Hell, you don't even need to make five copies of the sprite in the layout... you could Destroy On Startup and make a loop that creates five sprites and numbers their var 1 - 5.

Ok... thanks, but wtf?

First I haven't found anything explaining

"" & Sprite.Value('var')[/code:2nyqp1db].
Ok ampersand means add to the variable, but [code:2nyqp1db]""[/code:2nyqp1db] means huh?
Second, every time I add a private variable, it automatically creates an initial value no mater what I do.

Well... image points can be referred to by name or number, yeah? And they're named 1, 2, 3, 4, and 5. So I added "" to indicate that it was a string, so as to reference the point by name. Then I put in & which is the string concatenator.

Second, every time I add a private variable, it automatically creates an initial value no mater what I do.

So change it in properties. Different instances of objects can have different values in their private variables in the layout.

Or, as I mentioned before, with a loop at runtime. Either way will work.

Alright I get it now, thanks.

See I didn't know that was possible, did not know that each additional object dropped on the layout could have its own specs. Hidden feature I guess.

Thanks again, now I've got tons to play with.

That seems like a backwards and undocumented way of doing it... Can't you just use str()?

NO!

Well I don't know, maybe. I never tried.
