3D animated wiper

i have make a 3d animated wiper that can freely turn on/off using bvec ats plugin, but i have a problem, the wiper blade only using translate x function.
so the blade not follow the handle curve and when plugin disabled the handle position gonna use the last value not turn original position.

did anyone know how to write it properly ?


the code for the handle is

Code:

[Object]
States= handle.b3d
Position= 0, 0, 0
RotateZDirection = 0, 0, 1
RotateZFunction = if[pluginstate[64] < 1, cos[time/0.2]*0.52 + 0.52, value]

for the wiper blade

Code:

[Object]
States= blade.b3d
Position= 0.265, 0.455, 0
translatezDirection = -1, 0, 0
translatezFunction = if[pluginstate[64] < 1,if[value >=0,cos[time/0.2]*0.265 + 0.265, value], value]
