Thanks Roger, works beautifully

Thanks Klaus , I downloaded 7.02 and tried, but no luck the error persists

a pendulum WITH a line that does NOT disappear on my machine and many others. If your copy's pendulum line disappears, perhaps we can help you with that problem, first of all?

Thanks Roger :D ,

You are right. On my machine it disappears and is turned into a point. I'm running version 7.0 ...

Yes but it disappears as soon as you start the pendulum.

A rotation of a simple line shouldn't be rocket science, and the fact that LC has no support for it is somewhat dissapointing

Thanks Simon ,

but it doesn't quite answer my question. There was a link there that didn't work and the Harmonic oscillator stack didn't have a line for it's pendulum. So does it mean seems that there is no simple solution?

I have a line that is a radius vector in a circle. I want to rotate the line 30 degrees counter clockwise when I click on a button. Is that possible? (Rotate "angle" does not seem to work for a line graphics. Also I want to rotate around the end point of the line, like a upside-down pendulum.)

I generally don't worry about script sizes (the compiler doesn't care.) I've got scripts that are a couple of thousand lines or more without ill effects. The reason I limit the length of handlers is for easier maintenance and modularity, but I find it more difficult to maintain code that is too ...

My general rules are:

If code is needed more than once, break it out into a separate handler.
If a handler gets too long, break it up into separate handlers (a 300 line handler is way too long.)
Place handlers at the level closest to the objects that use them. If a single button uses some code ...

I know this is not an easy question and probably people do it differently, but still I would like to know different ways of organizing your code in LC.

Say I have a program of totally 6000 lines of code. Some in controls, some in cards, some in mainStack. Some handlers are 300 lines long others ...

Thank you Richard, just what I was looking for
and with blending I can make it semi transparent too

When I open a substack with
modal stack "ModalDialog"
it appears in the middle of my 2400x1400 screen, which is half a mile from my main stack :evil: . Is it possible to position the modal dialog, closer to the main stack? If not is there a way to use sheets like in a normal Cocoa application (a ...

Hi Jean-Marc, thank you for your answer :D ,

So you are referencing images instead of importing them. Here is what I suspect, please correct me if I'm wrong

PROs of referencing
- takes much less space in your stack.
- you can change the image without changing the stack

CONs of referencing
- If ...

When do you use Image Area and when do you use a Button Icon, when you want to display an image on a card?

Would it be possible to create a frontScript that trapped all mouse and keyDown events? Just a thought*.

Here is a little experiment you can do. Create a stack and on a card, add two buttons called "answer" and "myFront". Make their scripts look like this:

-- answer
on mouseUp
answer "How are ...

This works and this works but not this According to User Guide p154 all should work

I must be missing something very simple
