Elipse Movement Behavior for Opacity & Size

[Kenabi]

Right now only positions are possible. Using it for opacity and size could be handy.

Using Sin or Cos extension is not always possible because for a continuous action you can’t use „trigger once“.

[per]

Use sin() and cos() for this purpose. No extension required.

Typically: Object.X = sin( TimeFromStart() * f )

[davy]

This extension uses events, you can duplicate the extension and modify it for your own usage.

Also, I guess what you described is similar to this behavior:

Can’t make sense of this statement. It’s the conditional that uses Trigger Once, not the action.
