amazon web services - How to handle users data in an aws-based serverless stack -


i'm first-timer aws , i'm bit lost. have serverless stack using cognito handle authentication, dynamodb, lambda , cloudfront exposing rest services.

i don't know how handle users data. example, store user email , physical address. i've seen can have directly in cognito, however, perform custom validation when these attributes set/updated.

can trigger, letting user have write access on data?

or should restrain write access these attributes , expose rest service update them manually in lambda?

i've seen using users table in dynamodb store data, advantage compared using directly identity pool?

thanks,

you can store kind of data(email, address) in cognito user pools , validate data using presignup lambda trigger, more details.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
