Naming the speed of visual effects with variables

[Fermin]

Hi. Please,

Is there a way to invoke the speed of visual effects ("very fast", "fast", "slow", "very slow") with a variable?

Code: Select all

put "zoom out" into nameVF
put "very slow" into velVF
--
unlock screen with visual effect nameVF very slow -- Works fine
unlock screen with visual effect nameVF velVF -- It does not work

Thank you very much

Hi Fermin,
It seems "do" way works

Code: Select all

put "zoom out" into nameVF
put "very slow" into velVF
do "unlock screen with visual effect" && nameVF && velVF
Best regards

You don't need to "do" it if you resolve the name and speed to one argument for the effect:

Code: Select all

unlock screen with visual effect (nameVF && velVF)

It works very well. Thank you very much.
It would be great if instead of those words (slow, very slow, etc) could use a numeric value but I guess LiveCode not allow that.
Anyway, I say thank you both.

LC DOES in fact allow this, check "the effectrate" in the dictionary.

This manages the exact time in millisecs that a "very slow" effect will take!
Yes, the "very slow" effect, which is a bit mentally challenging

Code: Select all

...
lock screen
## We want a duration for our visual effect of 300 millisecs
set the effectrate to 300

## Or whatever should happen with a visual effect
show img "an image"
unlock screen with visual dissolve very slow
...

Best

Great, Klaus, is exactly what I need. I had not noticed that in the manual. Thank you very much.
