OK - give this a try. In a fresh comp, create a null and name it "template". Animate it tracing out your path over a fixed period (say 4 seconds). Use roving keyframes so the speed is constant. Add a slider (range 0 to 100) to "template" and name the slider "travel". No...

You'd have to write an expression that loops through the timeline frame by frame to check for the event.

Or else, you could write a script to find the event and leave the time in a slider value - something like that anyway.

2D rotation? It would look something like this:

-comp("main comp").layer(thisComp.name).rotation

If you can convert the excel file to a text file (in a format that a script can make sense out of) it shouldn't be too tough.

Dan

Yes, and if you do it that way you'll also have to go into the duplicate main comp and replace the instance of the template map comp with the new duplicate of that comp.

I think your other idea is better - move the maps into the main template.

Dan

Did you try adding app.quit() to the end of your script?

Dan

I see what you're saying now. It appears to be broken in a strange way. I get a cluster of files with the same time and then another cluster with a different time, etc., when each file should have a unique time. Strange.

I just ran your script and got:

Sun Mar 07 1999 08:26:40 GMT-0800

(Which interestingly is an hour off what Windows Explorer says).

I don't have a clue as to why it doesn't work for you.

>Does this usually work ? Yes, you only have to copy the data from Notepad, select the target layer, and paste. The keyframe data will find it's way to the Position property (AE 6.5). >Am I doing something wrong ? Somewhere in the process. Does your keyframe data in Notepad look something like this:...

Do a side-by-side comparison of the text generated when you paste AE position data into a text editor with the the text generated by your script. The header stuff has to match exactly. Maybe your script was written for an earlier version of AE?

Dan

Byron, I'm not sure exactly what you're trying to do. Do you want the animation in the precomp to start at the time where the marker is in the main comp? If so, you need to calculate your offset based on the difference between the time of the first keyframe (comp("Main Comp").layer("N...

The only thing I can think of is turning off the preference that enables the debugger. Kind of a pain though.

Dan

I think most of the key points have been mentioned, but let me contribute my simplified summary. Part of the confusion stems from 'propertry' not meaning the same thing in AE scripting as it does in JavaScript. I think this is because layers had 'properties' before AE had scripting. In AE, a propert...

Just using a simple script like this:

alert(PropertyValueType.NO_VALUE);

I get

NO_VALUE = 4812
TwoD_SPATIAL = 4815
CUSTOM_VALUE = 4819
MARKER = 4820
MASK_INDEX = 4822

Dan

Change your expression to something like this:

value*thisComp.layer("Null 1").effect("Slider Control")("Slider")/100

With the slider set at 100 you'll get your original animation. Adjust to suit.
