func AppCall

func AppCall(scriptHash []byte, args ...interface{}) interface{}

AppCall executes previously deployed blockchain contract with specified hash (160 bit in BE form represented as 20-byte slice) using provided arguments. It returns whatever this contract returns. Even though this function accepts a slice for scriptHash you can only use it for contracts known at compile time, because there is a significant difference between static and dynamic calls in Neo (contracts should have a special property declared and paid for to be able to use dynamic calls). This function uses `System.Contract.Call` syscall.
