joyhandle − joypad handle |
|
loadrt joyhandle [count=N|names=name1[,name2...]] |
|
joyhandle − sets nonlinear joypad movements, deadbands and scales |
|
loadrt joyhandle [count=N] |
|
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 symetrically 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. |
