joyhandle - sets nonlinear joypad movements, deadbands and scales
loadrt
joyhandle [count=
N|names=name1[,name2...]]
The component
joyhandle uses the following formula for a non linear
joypad movements:
y = (scale * (a*x^power + b*x)) + offset
The parameters a and b are adjusted in such a way, that the function starts at
(deadband,offset) and ends at (1,scale+offset).
Negative values will be treated point symmetrically to origin. Values -deadband
< x < +deadband will be set to zero.
Values x > 1 and x < -1 will be skipped to ±(scale+offset). Invert
transforms the function to a progressive movement.
With power one can adjust the nonlinearity (default = 2). Default for deadband
is 0.
Valid values are: power >= 1.0 (reasonable values are 1.x .. 4‐5, take
higher power‐values for higher deadbands (>0.5), if you want to
start with a nearly horizontal slope), 0 <= deadband < 0.99 (reasonable
0.1).
An additional offset component can be set in special cases (default = 0).
All values can be adjusted for each instance separately.
