When someone does something, like subscribe or provide a gratuity, performs an action such as giving you their head or spawning a chance cube.

Do Stuff On External Action relies on a lua file to provide the user the ability to determine what needs to be done. The following lua functions are implemented:

oas.currentPlayer.sendMessage(String) - Send the current player a message in chat.
oas.currentPlayer.isDead() - Returns a boolean whether the current player is dead.
oas.delayedExecution(Function, Delay) - Runs Function in Delay milliseconds.
oas.setBlock(BlockIdentifier, [NBT]) - Sets block at current player's current position, BlockIdentifier being the registry name of the block (ex: "chancecubes:chance_cube"), NBT being optional, a JSON string epresenting the NBT data to give the TileEntity.
oas.streamlabs.registerCallback(Function) - Registers a function Function to run whenever StreamLabs sends you something.
oas.primeSkinCache(Username) - Allows you to prime the Minecraft skin cache for all players on the server you're playing on, so as to avoid a lag spike when spawning a head.
oas.generateFireworksEntityNBT() - Helper function to generate a random firework's NBT data.
oas.spawnEntity(EntityIdentifier, [NBT]) - Spawn an entity with the registry name EntityIdentifier, NBT being optional, a JSON string representing the associated NBT data.
oas.consoleLog(String) - Log String to the Minecraft logs.
oas.generateItemEntityNBT(ItemName, [count, [damage, [NBT]]]) - Helper function to generate the NBT data behind the EntityItem, count, damage, and NBT being optional, requiring the previous items if you need each item.

Note - While no changes to this API are anticipated, they are not ruled out.
