Left SideEdit

Only looks for objects that are neither moving nor doing an action.

[stationary Crate] [?] -> [stationary Crate] [Checkmark]
[moving Crate] [?] -> [moving Crate] [Cross]

The player is only stationary when realtime_interval is turned on, or when made that way with the right side of a rule.

Right SideEdit

Makes something stop moving or stop doing an action.

[left Player] -> [stationary Player]

If referenced on the left side but not the right, nothing changes.
