感谢感谢,其实也看了NRcounter节点的使用说明,也看到了以下使用说明:
Control
It's possible to control the counter with incoming msg properties:
msg.increment: counter will be incremented by the given value.
msg.decrement: counter will be decremented by the given value.
msg.reset: resets the counter to it's initial count, or to the given value, when it's a number.
