Dashed line

[petero]

I have tried, unsuccessfully, to create a dashed line (arrow) in Revolution. I would like to eventually do this in a script but I can't even do it when in edit mode. I have checked the properties dashed lines box, I have tried transcript (setting the dashed lines property). Nothing seems to do it. I am creating in OSX.

Any suggestions would be appreciated.

have you tried turning off antialiasing?

All the best,

Hi Peter-O,

From the docs for "dashes":
##...
Cross-platform note: On Mac OS and OS X, and Windows 95/98 systems, the dashes property cannot control the length of dashes and blanks: setting the dashes to any non-empty value at all creates a dashed line, but the length of dashes and blanks is controlled by the operating system.
##...

And yes, looks like this only works for not antialiased graphics at all.
Ergo: Hardly usable

And ... this is also true today?

The anti-aliased line looks awful.

It would not be hard to make your own, with a line graphic and a bunch of other opaque borderless objects all grouped together. I don't know how much you would need to manipulate this thing, though you could certainly could virtually make a new "object", with settable gap widths, etc.

Hi Mag,

And ... this is also true today?

why not make a quick test with a graphic yourself?

It works with LC 6.6.1 and does not look awful when antialiased, see screenshot.
"dashes" are set to 30,20 in my example.

Hi dunbarx and Klaus, thank you so much.

Klaus, where are the dashes property? I had not find it in the inspector... OK, I will search the Dictionary...

[Klaus]

In the inspector right under the "linesize" field there is a checkbox to turn dashes on or off.
No interface to set the values unfortunately, you need to do this via script.

Thank you Klaus!

Hemann.

You sort of used "marching ants" (I am thinking about the "j" in your switch construction) in your handler. Adorable.

It does. All LC graphics have a "dash" property.

Place an arc below two lines oriented as you drew it. If anyone can make the dashes in that arc march, you can.

Simple way to create a dashed line

1) Draw a line
2) put the following code into the script of the line you drew

Code: Select all

on mouseUp
   set the dashes of me to 10,2
end mouseUp

Put the IDE in run mode and click line.
