Does readying an attack prevent me from taking a reaction. If I ready my attack, and a creature moves by, do I get the AoO?

The Ready action spends your action. If you take the readied action, your reaction is also spent. No reaction = no opportunity attack. #DnD https://t.co/4lMSsHwAdd

If I ignore the trigger for the readied action, do I get my reaction back? Can I take an AoO then?

With the Ready action, you don’t use your reaction until you respond to the trigger your chose. Until then, only your action is spent. #DnD https://t.co/5nB4TZ27rV

only your acrtion is spend? so after making the prepared action you can still move if you diden’t before ?Yes.
