How to wait until CDE target blockheight

[acedward]

When performing an action such as Contract Mint/Burn TX another CDE Blockchain (Different as game chain)
How do we wait until the event has been processed?

-- Workaround

1. Do and wait until the mint / burn is completed
2. Fetch the MAIN CHAIN current blockheight (not last processed)
3. Fetch Last Processed Block Height, and compare - if less then wait and fetch again. (If emulated. conversion is required)
