Triggering animation with layer markers

[chadinko1]

Hi Everyone,

I need help to refine this expression of triggering animation with layer markers.

I have animation of a text that starts with key 1 to key 2 and then this text transition to another text key 3 to key 4 and then text out key 5 to key 6.

The 2 texts layers are pre composed, and my expression is applied into the Time remapping with these 6 keys.

Basecaly, the expression works fine, just I'm getting expression error for this line 

if (time < T.marker.key(1).time)
linear(time,inPoint.time,key(2).time,key(1).value,key(2).value)
else

Everytime, I move my timeline indecator before my marker.key(1). But the expression keeps working fine.

This is my expression:

T = thisLayer;
if ((T.marker.numKeys > 1 ) && (numKeys > 5)){
dIn = key(4).time - key(3).time;
dTr = key(2).time - key(1).time;
dOut = key(6).time - key(5).time;
eIn = T.marker.key(1).time;
eOut = T.marker.key(2).time;

if (time < T.marker.key(1).time)
linear(time,inPoint.time,key(2).time,key(1).value,key(2).value)
else
value

if (time < T.marker.key(2).time)
linear(time,eIn,eIn+dIn,key(3).value,key(4).value)
else
linear(time,eOut,eOut+dOut,key(5).value,key(6).value);
}else
value;

Thank you for your help

Your branching in the conditional is wrong. The precedence is

if

else if

else

Also your code is sloppy. Even else statements require ( ). Fix your syntax and formatting and it should work correctly.

I'm new to expression, Can you please help me to fix the code.

Thanks

What is it supposed to do?

[chadinko1]

I have 3 animations In, transion and Out

The In can be always at the bigenning of the layer, first marker should trigger the transition and then the second marker should trigger the Out.

[Dan Ebberts]

In your code, it looks like the transition happens before the In, is that correct?

[chadinko1]

The In animation can always starts at the inPoint of my layer (it doesn't need a trigger). transition should be triggered by marker.key(1) and then Out should be triggered by marker.key(2)

In that case, I think it would be like this:

if ((marker.numKeys > 1 ) && (numKeys > 5)){
  dIn = key(2).time - key(1).time;
  dTr = key(4).time - key(3).time;
  dOut = key(6).time - key(5).time;
  eIn = marker.key(1).time;
  eOut = marker.key(2).time;

  if (time < eIn)
    linear(time,inPoint,inPoint+dIn,key(1).value,key(2).value)
  else if (time < eOut)
    linear(time,eIn,eIn+dTr,key(3).value,key(4).value)
  else
    linear(time,eOut,eOut+dOut,key(5).value,key(6).value);
}else
  value;

Working perfectly.

Thank you very much for your help, much appreciate it.
