Clinton Schramm is still having a problem:
Hi Jan
I have tried to implement what you said, but get the error "State object
has no attribute 'Pos'
Could you give an example on how to reference this correctly. Ideally I
would like to see the colour change based on the cummunulative
displacement from a certain point. (When the translation engine begins)
def checkUnbalancedtunnelmovement():
global voidcheck
if voidcheck==2:
O.engines=O.engines+[TranslationEngine(translationAxis=[0,1,0],velocity=0.05,ids=TBM)]
for s in O.bodies:
s.state.refPos[1]=s.state.Pos[1]
O.engines=O.engines+[PyRunner(command='Changecolor()',iterPeriod=200)]
print O.engines, '2'
voidcheck=1
# start plotting the data now, it was not interesting before
#O.engines=O.engines+[PyRunner(command='addPlotDataForceTunnel()',iterPeriod=200)]
checker.command='calculateforces()'
def Changecolor():
for s in O.bodies:
s.shape.color=scalarOnColorScale(s.state.displ().norm(),0,.7) #
for changing color based on the movement of sheres.
