A common error is to assign an eventIn to an eventOut directly by name (see below). It looks correct, but it doesn't work because an eventIn in a script is actually a function (with the same name as the event). This function contains data elements (the value and time arguments). The eventOut, on the other hand, is itself a data element.
In the following example, value is the data element of the startFloat function. This variable is assigned to the outFloat eventOut.
/////////////////////// FIELDS ///////////////////////////////// eventIn SFFloat startFloat eventOut SFFloat outFloat /////////////////////// BEHAVIOR ///////////////////////////////// function startFloat(value, time) { outFloat = startFloat; // WRONG!!! outFloat = value; // Correct. }
