I need to spend this week towards the trainyard, debugging the map making sure the assets have correct collisions. Checking the outer walls to make sure the player cannot see outside the map.
The helicopter starting animation can be seen idle. Fixed by hiding a building in front of the helicopter.
You can see down the tunnels at train yard. Fixed by adding smoke.
You could walk down the tunnels. Fixed by adding an invisible barrier.
Player can see down the road area. Fixed by adding a building.
