# MessageBox - Async Modal Dialogs

Ask the player to confirm, and wait for the answer in place

## What this does

Your Unity project needs to stop and ask - are you sure you want to delete this, do you want to save - and wiring up a popup plus a callback is fiddly. This gives you modal dialogs you can await: alerts, prompts, OK/Cancel and yes/no. Use it wherever the code should pause for an answer.

### Top 3 things it does for you

- Show a yes/no confirmation before something destructive
- Ask before deleting or saving
- Wait for the user's answer before carrying on

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About MessageBox - Async Modal Dialogs

Async modal dialogs for Unity, built with UniTask. Alerts, prompts, confirmations, OK/Cancel and yes/no popups are all awaited, so the code that asked the question is the code that receives the answer.

It fits the moments a project has to wait on a person: confirming a delete, confirming a save, or any point where the flow should pause for user input.
