Parameters
|
||
|
|
----------
|
||
|
|
direction : float
|
||
|
|
kick direction relative to field, in degrees
|
||
|
|
abort : bool
|
||
|
|
True to abort.
|
||
|
|
The method returns True upon successful abortion, which is immediate while the robot is aligning itself.
|
||
|
|
However, if the abortion is requested during the kick, it is delayed until the kick is completed.
