Questions about agent`s state information in MADDPG

[zxm-NEU]

Take the three predators and two escapers in simple_tag as an example. I tried to print the status information of these five agents and got an array. The status information of good_agents is 18 and the status information of adversaries is 20. I would like to ask Now, what are these states and why are they inconsistent?

The difference lies in the variable "other_vel"

for good_agents, the variable "other_vel" is [ ]

for adversaries, the variable "other_vel" is [float, float]
