Howdy,

Will plugins that use the spline description element need to be rewritten to accommodate the new one in R13?

Adios,

Unfortunatly yes. Old scenes will import in a compatibility mode.

PS. I hope to get the R13 SDK docs up in the next two weeks.

Howdy,

So plugins in R13 will need new .h, .res and .str resource files, plus different code in the .cpp file?

I'm not sure I understand how the compatibility mode would work?

The resource files are still valid. There only seem to be some additional layout flags. The code has to be adjusted though, depending on what you are doing with the spline.

It only means that old files don't break.

This is what you get when you load an old file:

Well, can those flags be added in code and leave the .res files the same, then the .cpp file could contain:

#if API_VERSION < 13000
// older method
#else
// R13 method
#endif

...It only means that old files don't break.

OH, so the compatibility mode only applies to User Data splines?

No. This compatibility mode locks every spline control of old files. If your spline control uses other values, i.e. another range than [0,1], you will have a problem, because R13 now works with absolute values defined in the res file ersp. set by SetRange(...). So if you have defined a range of 0 to 100 in your res file, the points of the spline curve remain between 0 and 1 all the same when you click on the control to remove the locking.
