Swinging hinge effect for per-character 3d?
by Corbin Gross on Jul 2, 2009 at 5:46:10 pm

I'd like to have the characters swing down and settle. I can do it per word or line with an expression on the rotation of the layer but I'd like to do it using the per-character if possible.

Here's what it's for. Only I'd like them to swing and settle instead of just ramp to a stop.

Thanks

Sorry, thought I psoetd an answer to this last week,!

Here's how I solved this, though there's probably several ways to do it:


  • Create a text Layer

  • Enable Text->Animate->Per Character 3D

  • Add an animator "Rotation", and set X-rotation to +90° (or-90°, or whatever is the starting rotation)

  • Adjust Text->More Options->Grouping Alignment to 0,-100% (this makes the rotation hinge around the top)

  • You can delete the Y and Z rotation properties

  • Delete the "Range Selector"

  • Now add an "Expression Selector“ to the Text Animator

  • twirl down the Selector->Amount and paste this expression:


    delay=0.06; // amount of seconds between each letter
    swings=1.5; // number of times the text will swing before it's done.

    t=valueAtTime(time-delay*textIndex)[0];

    amt=Math.cos(t*Math.PI*(swings*2)/100)*easeOut(t,0,100,100,0);

  • Now to animate the swinging, set keyframes for the amount between [0,0,0] and [100,0,0]

  • You can tweak the expression, I think it's pretty self-explanatory



You can add further properies to the same animator, try for example:
X Rotation=60°
Opacity= 0
Fill Brightness=-80%
Fill Saturation= 40% (if your text is coloured

To get some fake 3D shading

I used another expression you posted to do something similar. Have'nt used this one yet, looking to make the text swing in from above instead of from below. can this be tweaked to solve that?
