Hi I need help making clones only go to the primiter of the stage like the clones teleport randomly to one edge of the stage and I don’t know how to do it?
not sure why that's a question, but ok.
What in the world is a primiter?
what do you mean by that? each clone goes to a random part of an edge of the stage, or each clone goes to one point of any of the four edges of the stage?
why was this flagged?
perimeter
I'm pretty sure they mean perimeter.
go to([left V] of [stage V])
There's also right, top, and bottom of stage, which gives the coordinate for either edge of the stage/screen.
go to x: (item (pick random (1) to (2)) of (list ([left V] of [stage V]) ([right V] of [stage V]) $<>)) y: (item (pick random (1) to (2)) of (list ([top V] of [stage V]) ([bottom V] of [stage V]) $<>)
There might be a less complicated way, but that's just the first thing that came to mind.
It depends on whether you want the center of the sprite at the edge of the stage (relatively easy) or you want an edge of the sprite at the edge of the stage (a little more complicated arithmetic). GO TO X: Y: puts the center of the sprite at the given position, so if that's what you want, you can just put, e.g., LEFT OF STAGE into the X: input slot. (I'm guessing you'd then want Y to be randomly chosen between TOP OF STAGE and BOTTOM OF STAGE.)
If you want, e.g., the left edge of the sprite at the left edge of the stage, then the X coordinate has to be increased by half the width of the sprite (WIDTH OF SELF). Similarly for the other edges.
Thank you!
The sprite is on the middle of the stage
you could also just use if on edge, bounce to do sprite fencing, no complex maths required!
It's not very complex at all.
It would be slightly different for the other edges, but it's still very simple math (no dividing my width at all).
Yeah good point, you're right.
I just want to add that this:
Will only go to one of the corners. To go anywhere along the edge, you could do this:
I know that it is complicated, and there probably is a better way to do it, but let me break it down for you:
In this case, we are trying to create a list of all the possible coordinates on the edge of the stage so we can pick a random one using the "item random of list" block. For a sprite to be on the edge, it needs to either be on the left, the right, the top, or the bottom. First let's make a list of the coordinates on the left of the stage. These are all the y values:
However, we still need the x values. The x value must be equal to the left of the stage for each and every item. Let's make a list of the same length with all the values being the x coordinate of the left of the stage:
Now, let's combine these two lists:
Bam! All the coordinates on the left of the stage! Now, if we do the same for the right, the top, and the bottom of the stage, we just need to combine, or APPEND the lists together:
Good luck with your project!
PS: This method also relies on the fact that if you put a two-item list in the "go to" block, it will treat the first item as the x value and the second item as the y value.
Here's a pretty old script of mine that surfaced not too long ago that makes the sprite go to any position on any side of the stage.
(sorry, I can't remake it in snap to allow this script pic to be imported into snap)
maybe use combinations @list@list@<:>?
Thank you!
