Hi there,
i created a class for several calculation. But there is a problem and I can't fiure it out. :(
import c4d
import math
class distr_functions() :
def __init__(self) :
pass
def CalcLin(x,xmax) :
return x/xmax
def CalcPot(x,xmax) :
return math.pow(x/xmax,2)
def CalcExp(x,xmax,strength = 200) :
return math.pow(strength,x/xmax)/strength
def CalcCos(x,xmax,puls = 1) :
return (-0.5)*math.cos(x/xmax*pi*puls)+0.5
def CalcSwitch(x,xmax,switch,third = 1) :
if switch == 0:
return self.CalcLin(x,xmax)
elif switch == 1:
return self.CalcPot(x,xmax)
elif switch == 2:
return self.CalcExp(x,xmax,third)
elif switch == 3:
return self.CalcCos(x,xmax,third)
else: return
def main() :
df = distr_functions()
print df.CalcLin(4,4)
if __name__ == "__main__":
main()
The console tells me:
CalcLin() takes exactly 2 arguments, 3 given
But it works perfectly if i don't put these functions into a class.
What did i wrong in defining the class ?
And can i import a module for a class , like for eg the math module ?
Thanks, nux
