In the documentation (and posts on the web) visual effects is used like this:
[/code]

In my world this yields an "unquoted literal" error....

Passing the effect as parameter works
[/code]

Can someone explain??

TIA,
Kai

Hi Kai,

very strange.

...
visual dissolve
go next cd
...

visual effect dissolve
go next cd
...

Both work without problem.

That's what I thought!

2.8.1 Build 470
OS X 10.4.10

Does anyone else see this? Maybe my Rev install got damaged somehow?
Which files should yield which checksums?

Thanks for any help

Have you turned on variable checking in the preferences? Are explicitvars true? In both cases it will throw an error.

All the best,

Yes, Malte, indeed I have.

But what's the solution then? I do not understand how these things relate?

If, for instance, the 'dissolve' is really a variable parameter it must already be defined for the engine to act upon it. So why would the engine bitch about it (irregardless of these settings)?

TIA,
Kai

Hi Kai,

one could argue that the expected syntax needs quotes and that the engine is forgiving enough if you forget them if explicitVars are false. It needs to be quoted, as it is a literal string and not a predefined constant like hand for example. Try in the messagebox:

put hand ->28
put dissolve -> dissolve

The script editor does the following if you check variables. When compiling the script it sets the explicitVars to true before compile and to false directly afterwards.

From the docs:

If the explicitVariables property is true, using a literal string without enclosing it in quotes causes a compile error.

So I *think* it is correct that the engine bitches about it. However, that's just me.

All the best,

Malte

Excellent explanation - but then the Rev people really need to clearly mark these cases in the documentation - I certainly thought I was dealing with predefined constants (which they really could - and should? - be)

Thanks,
Kai
