Hi All,
I'm making a silly little animate function for my app.
Let's say I have a grc "new". I'd like to be able to animate it like this:
animate (the long name of grc "new", "loc 100,50;width 40%;height
50%;foregroundColor 255,0,0",200)
How do I pass the name of a custom property, and then use it in a statement?
So, the intent of the function should be pretty clear:
Assuming n frames per second, we have nf = n*200/1000 frames to play with.
Each attribute should change 1/nf between the start value and the end value.
I'm making this up as I go, but something like the code below. Can
anyone point out how to dereference the name of a custom property just
after the asterisks?
-- pAtts and pTime is only passed the first time
on animate pObj,pAtts,pTime
if the animating of pObj is false then
-- set up animating
-- make sure we always get at least 1 frame
put max(n*pTime/1000,1) into nf
split pAtts by ";" and space
set the pAtts of pObj to pAtts
repeat for each line aKey in the keys of pAtts
-- this next line is where I'm stuck...how do I use
-- the value of 'aKey' as the name of the custom prop
-- instead of setting the custom prop name to be "aKey_delta"
-- below? *******************************
set the aKey&"_delta" of pObj to (<cur>-<new>)/nf
set the timeslice of pObj to 1/nf
set the numberOfFrames of pObj to nf
set the curFrame of pObj to 1
end repeat
set the animating of pObj to true
send "animate "&pObj to me in 1/nf milliseconds
else
-- we're animating, so the delta's should exist
if the curFrame of pObj < the numberOfFrames of pObj then
set the curFrame of pObj to (the curFrame of pObj + 1)
put the pAtts of pObj into pAtts
repeat for each line of the keys of pAtts
-- do the math to modify the attributes by deltas
end repeat
send "animate "&pObj to me in 1/nf milliseconds
end if
end if
end animate
Thanks!
-Ken
