Pseudo Effects Default Expressions

[braydenblythe]

I’ve created a Pseudo Effect that has multiple slider controls, amongst other things. I need the slider controls to have default expressions already applied to the Slider whenever the Effect is applied.

I am able to apply default values, but is there a way to apply expressions in the same way? Here is part of my XML file for reference:

<Effect matchname=”Pseudo/TextTool_Offset” name=”$$$/AE/Preset/TextTool_Offset=Text Tool Offset”>

<Group name=”$$$/AE/Preset/AnimationIn=Animation In” >

<Slider name=”$$$/AE/Preset/XStartPosition=X Start Position” default=”0″ valid_min=”-1000″ valid_max=”1000″ slider_min=”-100″ slider_max=”100″ precision=”2″ />

<Slider name=”$$$/AE/Preset/XEndPosition=X End Position” default=”0″ valid_min=”-1000″ valid_max=”1000″ slider_min=”-100″ slider_max=”100″ precision=”2″ />

<Checkbox name=”$$$/AE/Preset/Mirror=Mirror” hold=”true” default=”true” />

</Group>

</Effect>

I need this expression to be applied to the “X End Position” slider:

if(effect(“TextTool_Offset”)(“Mirror”)==1){

-(effect(“TextTool_Offset”)(“X Start Position”))

} else {

value;

}

This expression takes the inverse of X Start Position if the “Mirror” checkbox is checked. If not, it returns the value.

This Pseudo Effect will be apart of a script, so it’s important that the expressions load in by default. Any help would be greatly appreciated!

You could apply your effect, your expression, select the effect, and save it as a preset.
