[X3D-Public] SFTime.setValue()

[Giorgos Papadakis]

Thanks for your quick reply.

The specifications of the methods are that getValue() returns a double and
setValue() gets a double as an argument so it still seems right to me.

Moreover the exception is thrown at the first line,

My feeling is that you should explicitely convert the timein.getValue()+2.0
to an SFTime value... 

As you wrote the code I think that it is trying to put directly an integer
value into a SFTime slot... and I guess that this is not acceptable.

 

cheers,

Hello, I am having some troubles with SAI (script called inside an x3d
world).

My code has an input SFTime value, routed from an TouchSensor, and I want to
use this to trigger an animation (startime=input and stoptime=input+2.5
seconds)

I am trying to do this at the following simple code:

 

timeoutstart.setValue(timein.getValue());

timeoutstop.setValue(timein.getValue()+2.0);

 

When viewing the world using the Xj3D browser, I am getting the following
exception:

This happens only with SFTime variables, I have successfully changed  an
object's position and orientation using similar code.

I appreciate any help you can give me.

Thank you in advance,

Giorgos.
