finding the asset id for a roblox decal or sound

audio's the other trap. since roblox tightened audio privacy, a sound only plays in your game if it's public or you've been given permission to use it. so if you've got the right id and it's still silent, that's usually why.

The number in the item's page URL is the asset id. In Studio you can also right-click the item in the Toolbox and copy the asset id from there. The bit that catches everyone: a decal id is NOT the image id. If you paste a decal id into the Image property of an ImageLabel in the Properties panel, Studio quietly converts it for you. In a script it doesn't, so you get a blank image. Paste it into the property once, then copy the rbxassetid:// number it changes to. For sounds, the audio has to be public or shared with your experience, otherwise the id is right and it still won't play.
