Framsticks

Optional "dirent" implementation, may be needed for some Windows compilers

Introduced XY::extensionContaining()

Updated for the new way of handling of dictionaries (where null is allowed as key's value)

Code formatting

Updated for Framsticks50rc14.

Notable changes for the script creators:

• more descriptive field names for Creature and Population (e.g. Creature:perf_measuring, nn_active, physics_active, ... Population: intitial_perf_measuring...)
• Dictionary.hasKey(), for(item in dict) ... , for(key in dict.keys) ...
• _propertyAdd/Remove/Exists... etc. functions (instead of many unrelated names) in ExpProperties? and ExpState?

Added XYRect::fitAspect(float aspect)

Added a helper function to concatenate path components inserting PATH_SEPARATOR_CHAR

Tester no longer exits on popular exceptions like 'file not found'

corrected f1 geometry goal (incorrect because of the solid shapes model conversion bug fixed in r900)

corrected test goals filenames

Ensure consistent rotation data when building a solid shapes model: use part.setRot(...) instead of part.rot=...
