# create_comm_channel

> Creates a new BindableEvent with Instance.new, stores its Instance reference in the communication channel list under a numeric channel ID, and returns the ID plus the BindableEvent Instance. The channel ID is computed from the current map size plus one. If Instance.new("BindableEvent") does not leave a object value on the stack, the function raises "Failed to make a BindableEvent".

<div className="real-function-page">
  ```lua theme={null}
  create_comm_channel(): integer | Instance
  ```

  ## Returns

  <ResponseField name={"channelId"} type={"integer"}>
    Numeric channel ID inserted into the communication channel list.
  </ResponseField>

  <ResponseField name={"event"} type={"Instance"}>
    BindableEvent Instance stored for the channel and returned to the caller.
  </ResponseField>

  ## Example

  Create a BindableEvent communication channel and keep the returned channel ID for later lookup.

  ```lua theme={null}
  local channelId, event = create_comm_channel()

  print(channelId)
  print(event)
  ```
</div>
