usage of critic_value_new[dones[:, 0.0]] = 0.0 in learn()

Line 74 in a3c294a

critic_value_[dones[:,0]] = 0.0

Hi Phill,

Could you please help me to understand what's this line is for?
critic_value_new[dones[:, 0.0]] = 0.0
Since critic_value_new float variable it cannot be used as array. Should we set just dones[agent_idx] to 0?

Thanks and Regards
Viji
