Version: 0.3.1
|
||||
Date: 2020-08-17
|
||||
Features:
|
||||
- If the player is inisde a spidertron while in follow mode, they will not move to the 'mean' of the squad
|
||||
- Regular remotes can be used on spidertrons to relocate their position in the squad
|
||||
- Regular remotes can be used on a spidertron with a player inside of it to move it and the squad to a position

This means we need to calculate the mean of the entire squad if one has changed position.
