Help with automated changing in the y axis with clones.

Skeelix

I have created a system where when the space key is pressed it clones and goes under the clone before it, this happens until it hits the bottom of the screen, where it will then stay there, this is due to screen limits where sprite cant pass the screen, I need to automate a change on the Y axis where when there is 10 blocks, the first block along with all the others will move up to create room for a new block to be placed.

you could try:

when I start as a clone
...
forever
if <[-180 + 1/2 of sprite costume height (rounded)] > (y position)> then
broadcast [move up v]
end
end

when I receive [move up v]
change y by (sprite costume height)

To find the height of a costume, just go into the costume editor and look at the costume's icon on the left side. Just below it there should be its dimensions

That message will broadcast for all the clones and the original sprite, so you might have to deal with that moving the original sprite by moving it back.

I like this a lot, it seems to be working way better than what I had, but now there is a new issue, the broadcast seems to repeat twice in some parts, and multiplies its change in Y over time the more you click, I'm not sure how to explain this very well so ill link the project below.

Clones also react to broadcasts! So, the following code…

when green flag clicked
set [score v] to [0]
create clone of [myself v]
broadcast [increase score v]

when I receive [increase score v]
change [score v] by (1)

will actually increase the score twice!

To fix this, we can use a variable set to for this sprite only to keep track of what is a clone, and what is the original sprite. In the following code, the is clone? variable is set to for this sprite only.

when green flag clicked
set [score v] to [0]
set [is clone? v] to [1]
create clone of [myself v]
set [is clone? v] to [0]
broadcast [increase score v]

when I receive [increase score v]
if <(is clone?) = [0]> then
change [score v] by (1)
end

I hope this helped!

Thanks!!, ill try this now!!

I found a possible bug (relating to the movement of the clones): for some reason, they keep going up more than 32 spaces (even after you implemented @MrKingofScratch's solution) Seemingly the way to fix this is to remove the

repeat (6)
change y by (((global y) - (y position)) / (3))
end

Warning: this does hide the first clone under the main sprite for some reason.
To fix this, just add

change y by (-32)
