RE: scripting - current frame returned but...

["Halfdan Ingvarsson" <hingvars(at)Softimage.COM>]

Make sure the scop is set to “Always update”. Since there is no input, or none of the inputs is dirty, the scop doesn’t get automatically updated on frame change.

A mistake...thanks Stephen.

But even with the correct value ( CF ) it doesn't work.
In fact it works only once like a standard script.
If a click "Apply" in the script operator editor at frame 1 then the object position is set to 0,0,0.
If I click "Apply" at an other frame it is set to 5,5,5. But if I hit play for example, it doesn't update.

Thanks Ben,

I also used a custom parameter with an "Fc" _expression_ in the past but I'm just curious to know why it doesn't work like this with "In_UpdateContext.CurrentFrame;" as XSI logged the correct frame ???

I pass in the current frame as a parameter to the scripted op and then
set that parameter to have an _expression_ of "Fc". So it would be
In_UpdateContext.parameters("currentFrame").value instead.
