opencard and visual effect

[Ralph DiMola]

The rendering get done after preOpenCard completes. In preOpenCard you can set up your data and geometry before the card is displayed. Try timing from the start of preOpenCard to start the openCard handlers.

hm, not sure, I made a test here by myself.

Button to go to next cd with a visual effect:
...
put the millisecs
## go_next is in the stack script and goes to the next card:
## lock screen for visual effect
## set the effectrate to 300
## go next cd
## unlock screen with visual wipe left very slow go_next ...
Then on the "next" cd I scripted:
-----------------------------------
on opencard
  put the millisecs into tMillisecs
  put CR & tMillisecs after msg
end opencard
-----------------------------------
And I ended with this in the msg:
1683043067873
1683043067877

Only 4 millisecs difference, but with the set effectrate the difference should be at least 300!?
So I guess "opencard" is already sent BEFORE the visual effect, at least according to the above data, right?

Molto mysterioso... :-)

Someone knows exactly?
