Unable to spawn the ego vehicle

[georgeliu233]

Hello~When I tried to use the 'roundabout' mode(spawn at designed point), it seems that the ego vehicle can not be spawned even after the max_spawn_time, I don't know what is going wrong, do you know?

This might because the traffic is very busy near the roundabout, and there might be always a car occupying the spawn point of the ego vehicle. You can try decrease the number of vehicles in the map.

I have figured out how to solve this problem. It may be due to the version difference. My Carla version is 0.9.13, which is higher than 0.9.6. I found that it is because of the " set_carla_transform" function that is self-defined in misc.py. The problem is that the transform.location.z is not given and automatically assigned as 0.0, and this is where the problem arises. We should get rid of this value and what I did is just assign transform.location.z to a value in (0, 1) and it works well right now. I hope this comment would help someone with the same problem.
