Oh, no, you didn't have to do that. I already had your previous link to follow. Anyway, the problem I can see with your script is that you're gliding all the way to the bottom and doing your sensing when you hit the bottom, which you don't want. What you do want is to do the sensing while you're moving down, which'll mean that you need another repeat loop to move you down a pixel until you hit the bottom. Just to show you what I mean, here's a smaller project showing what you need:

Helpful Project

If you can't open it due to the fact that you have a mod, then here's a picture of the code/comments, which you'll have to zoom in on to see clearly:



If you can't zoom in properly, just follow this link:

Oh boy we are getting there.  ive copied the script word for word, the only thing happening is some of the balls are hitting the peg and staying within the triangle

Does that make sense?

Also, what does the change y by -2 represent?

Not entirely, though to make sure, in your [change x by ()] block, you did use the operation that looks like this?

(((pick random (1) to (2)) * (20)) - (30))

Never mind..I take it was the mod block

You gotta love this * really....when it works

Time to test..................SUCCESS!!

I'll be back in 5, im off to run round the street naked

Do you want it to stack where it stops 1 block ontop of another, or can they stamp themselves over eachother?

There currently stamping over each over. I need it to stamp one of top of the other :-)

That is much harder than you'd think.
You'd need to have a way of collision detecting, with just one object.
It would be possible to have all of the end points saved in lists (possibly named "previousBallX" and "previousBallY"). You would then have to have a variable called imgH and imgW. Each one holding the height and width of the circle image respectively. It would be insanely slow, and I'll get to posting the necessary script in a little while (as it's quite long).

i think i am going to have to go ahead and submit my work as the deadline is noon tomorrow and i'll not get time to do so in the morning.  i havent had much sleep this week and working again in the morning.

I could however go and catch up with a couple of shows on tv?  I dont want to step on your toes

I appreciate that Ernie.  I have struggled with this for days and is only part of a very large assignment. i study form home so i dont have the privilege of speaking to teachers face to face. Its all for one and one for all so thats why i came seeking help if anything.

I would very much appreciate that, do you want a copy of the code so far to get you to where i am at?

You do know that there's a different, much easier way? In your repeat until loop, you just repeat until you're touching the edge or the color of a ball. Then, if your touching the color of a ball, then you just move up till you're not touching the color of your ball. Then you repeat the process over again. Now that I noticied that this was a HW assignment, I won't give you the script, though you should be able to fix it from what I've told you.

im getting it to stack but only 2 at a time. If a third goes down the same path it ust gets re-stamped?

Normally I don't like to give code for HW for obvious reasons, but since you can't see a teacher, I sympathsize. I'd like to look at your scripts again, though I won't  be able to see them till tomorrow because I have to go to bed now. Also, I won't be able to help till late tomorrow, so all I can say now is good luck!

I'm sorry about not posting the script, I had to go somewhere and didn't think it would really fit to say "g2g" on a forum.
Sorry, and it seems like you have it under control.
ErnieParke's way can be good, but there can be a few glitches that happen with it.
Some may be (I don't know really, as I haven't seen your project):
• The ball going through walls
• The ball not stopping
• Stamping over one another
• Going upwards when not supposed to

But those can happen in only certain scenarios, and it's WAY easier to start with his way.

Hi Lorddalron. We've been informed by representatives from OU that you are very likely a student taking coursework there.  This raises some interesting moral issues. 

On the one hand, it appears as though getting help on our forums is a violation of an agreement you have made with OU. On the other, getting help from online forums is an important skill for programmers to develop.

We want our forums to be a place for people everywhere to get help learning to program.  Speaking for myself here - and not the Scratch Team, whom I've yet to consult --  I don't think it makes sense for us to try to detect or prevent learning that may be in the service of completing a school assignment. In fact, I think finding outside resources to help with a school assignment is something that schools should reward. If an employee got help on a forum, and completed his task better and more efficiently, would their employer punish them for not doing it entirely on their own?

But this is a complex issue, born out of the increasing openness of a connected world, and there are many valid perspectives that should be heard. And my arguments above don't absolve you of responsibility for breaking an agreement with OU ( I'm assuming there is an explicit agreement about this. )

Given that you have an anonymous channel with which to share your thoughts on the issue,  what do you think?
