n
Remarks
Example:
7-310
Returns the x and y coordinates of two
joysticks.
v=STICK(n)
is a numeric expression in the range 0 to 3 which affects the
result as follows:
o
returns the x coordinate for joystick A.
1 returns the y coordinate of joystick A.
2 returns the x coordinate of joystick B.
3 returns the y coordinate of joystick B.
Note: STICK(O) retrieves all four values for the coordinates,
and returns the value for STICK(O). STICK(l), STICK(2),
and STICK(3) do not sample the joystick. They get the
values previously retrieved by STICK(O).
The range of values for x and y depends on
your particular joysticks.
