I’m trying to make an extension for a hardware device but need draggable parameters to make it work properly, could someone tell me how to use them? 🙂

You want `draggableParameters="reporter"`; e.g. here’s the definition for sprite overlap: [https://github.com/microsoft/pxt-common-packages/blob/master/libs/game/spriteevents.ts#L47](https://github.com/microsoft/pxt-common-packages/blob/master/libs/game/spriteevents.ts#L47)
