opencard and visual effect

[Craig Newman]

Klaus.

Why aren’t you doing this in the forum???

I made a stack with two cards. Card 1 has a button on it:

global tTime

on mouseUp

put the ticks into tTime

visual effect "checkerBoard" slow

go cd 2

end mouseUp



In the card 2 script:

global tTime

on openCard

put the ticks - tTime into fld 2

end openCard



I get about 60 ticks, so it seems the message is sent AFTER the visual effect completes. Know that with “preOpenCard” I get 0 ticks; the message is sent before the visual effect.
