[Bf-python] Some questions on 2.28 documents

Hi, Tatsuya!
Here are some answers to the (accurate) questions you asked.

Stephen already answered this one.

These 2 bits are only used if you use the curve to duplicate objects 
along the curve. They have corresponding buttons u can see when hitting 
F7 (animation windows)

Sorry. My fault. The minfac is not useful. It -was- a parameter for wave 
effects, but is now obsolete.

Returns the type of the effect : 0 : Build effect
                                                 1 : Particle effect
                                                 2 : Wave effect
The settype function is not really useful (transforming a build effect 
in a wave effect...hmmm...). But I wrote it because some other effects 
may be written later, and this function *could* be useful.

mode is a combination of 2 bits

bit 1 (last one) indicates the world has mist
bit 2 indicates the world has stars.

Sorry again. These parameters are used for internal computations in the 
mballs.
They should be removed, and it is usually a bad thing to change them.
They can (should) be discarded.


Thanks for your interest. I really like so accurate questions!
