Wiggle expression question
I’m using the standard wiggle expression
wiggle(1,1)
what do the two numbers represent.
when i apply expression my lay shifts greatly and then i use anchor point to put it back in it’s position where it will then wiggle. Why does it shift?
how do I use this expression to ramp-up the wiggle so that I can key-frame it to start out slow then build up its wiggle?
Can I apply a floor to the wiggle, so that the layer would not move below a certain point. Basically I want a boz to shake as if it were sitting on a surface. -

Read the manual, it’s all explained there! Still, let me help out this time. The numbers will be interpreted as frequency and amplitude. Your layer jumps because wiggle() will change its position (in AE [0,0] will always be used as standard start coordinates if you don’t explicitly assign other values). Use position+wiggle() to solve your imediate problem. Values can be animated by referencing sliders (Expression Controls -> Slider) instead of using fixed values. Search this forum, this question has been answered a million times already.

Thank you, I now understand sliders.
All needed was to realize that expression controls are in effects.
I still dont know how to create a floor for my wiggle though.
Any ideas? -
can someone point me to the language of expressions that would impose a “bottom limit” to a wiggle.
ex: position wiggles in x dimension freely but in the y dimension only in a positve direction so that the layer will never move below a certain level.
I have no clue how to do this.
Any leads? -
To limit your movements, use clamp(lower value, upper value).
