How do i get the assetid from the assets name?

Hello i have a question.

How do i get the assetid from a accessorys name for example.

If i only have the name of the accessory.

Lets say i dont know the id and i cant go to the Internet and find the item and see the id and i only have the name of the hat.

This could be: Supa Dupa Fly Cap.

How do i get the id of that hat in a script?

You would have to physically look up the ID in the Roblox library and import it into your script using rbxassetid. Then use that in a plugin.
