Sheep Herder

[44www]

Hello

I am new to this forum and to livecode. I have no programing experience but livecode seamed easy to learn.
I have bought the sheep herder tutorial from livecode Academy but i get this error: (intersect: two objects are required) near "&", char 83
I still get this error after i copy the code from the pdf I got for livecode.
I am using Livecode community 6.7

Hi 44www,

1. welcome to the forum!

2. Could you please post the relevant part(s) of the script that causes errors?
Not everyone has the Sheepherder stack at hand

Hello

I get the error here: if intersect (button("sheep"&x), graphic"pen","255") is false and intersect(button"sheep"&x),group"groupControls","0") is false then the problems seams to be in the red text.
I hope this helps you.

Hi 44www,

hmm, syntax looks correct!?
Sorry, no idea without looking at the rest of the stack/scripts.

The code so far:

local sLevel
on levelIncrease
put empty into sLevel
add 10 to sLevel
sheepGenerate
end levelIncrease

on sheepGenerate
lock screen
repeat with x=1 to sLevel
repeat
clone button templateSheep
set the name of the last button to ("sheep"& x)
set the loc of last button to random(320), random(480)
set the visible of the last button to true
if intersect (button("sheep"&x), graphic"pen","255") is false and intersect(button"sheep"&x),group"groupControls","0") is false then
exit repeat
end if
delete button ("sheep"&x)
end repeat
end repeat
unlock screen
end sheepGenerate

AH, I think I got it!

Ther are parens missing:
...
## if intersect (button("sheep"&x), graphic"pen","255") is false and intersect(button"sheep"&x),group"groupControls","0") is false then
if intersect (button ("sheep" & x), graphic "pen","255") is false and intersect(button ("sheep" & x)),group "groupControls","0") is false then
...
See the difference?

Hint: Add some spaces to your scripts for better readability!

The script that I put here was coppied from their pdf.... Great i paid for a lesson with errors in it. I thought about that too....

[Klaus]

So it works now?

[44www]

No the problem is still there

[44www]

The strange part is that I olso received a video tutorial. And in the video tutorial he doesn't get this error......

[Klaus]

No the problem is still there

Hm, OK, then it was not this...

[44www]

Good news.

I instaled 6.5 and put this script :

Local sLevel

on levelIncrease
put empty into sLevel
add 1 to sLevel
sheepGenerate
end levelIncrease

on sheepGenerate
lock screen
repeat with x = 1 to sLevel
repeat
clone button templateSheep
set the name of the last button to ("sheep"& x)
set the loc of last button to random(320), random(480)
set the visible of the last button to true
if intersect (button("sheep"&x),graphic"pen","255") is false and intersect(button("sheep"&x),group"groupControls","0") is false then
exit repeat
end if
delete button("sheep"& x)
end repeat
end repeat
unlock screen
end sheepGenerate

And it works fine.The problemed seamed to be with the 6.7(dp3)

[44www]

And there is a new problem.

The code that is presented in the tutorial does the opposite of what the tutorial says that it does .

I submitted a ticket , I hope they respond quickly........

[44www]

Good news.

The problem with the script is me . I was tired and didn't pay good atention to the tutorial and instead of > I placed a <......

Can someone explain this to me:

if the top of button ("sheep"&x) < the top of this card then
set the top of button ("sheep"&x) to the left of this card
end if

if the left of button ("sheep"&x) < the left of this card then
set the left of button ("sheep"&x) to the left of this card
end if

if the right of button ("sheep"&x) > the right of this card then
set the right of button ("sheep"&x) to the right of this card
end if

if the bottom of button ("sheep"&x) > the bottom of this card then
set the bottom of button ("sheep"&x) to the bottom of this card



Why in the blue code they are using < and in the red code they are using >. Does it have something to do with the right and left of the screen?

Thank you in advance.

This is because the left of the card is 0 and the top is also 0. This means that the top left of your card is the location 0,0

so if you do something like this in the message box:

Code: Select all

put the rect of this card

It will give you a number in a format like this : 0,0,480,800

this is the left,top,right,bottom

Hopefully this helps,
