Candy Wrapper

Candy Warpper is a library mod I use in many of my mods. You are free to use it in your mods.

Things made player riding possible:

• Redirect isSaveable() in addPassenger() to a custom method which returns isPlayer() if not saveable.
• Send EntityPassengersSetS2CPacket to the vehicle player when mounting or dismounting.
