- When you touch it, object Says module parameters


**** Commands [#gacf0737]

***** /6000 force value [#dd290e68]
- Set a kind of the external force
- value
-- 0 : Random Wind (default)
-- 1 : North Wind
-- 2 : East Wind
-- 3 : South Wind
-- 4 : West Wind
-- 5 : Rotational Wind

***** /6000 period value [#t05329c6]
- Set period of the external force
- When this Wind module is called times of this value,  Wind module restarts.
- If set 0, Wind module never restart by period.

***** /6000 strength value [#c995f4ad]
- Set Wind strength
- Default is 1.0

***** /6000 damping value [#r73d534c]
- Set damping rate of the external force
- Default is 0.85

***** /6000 wind_visc value [#jcf9fe7c]
- Set (scaled) viscosity coefficient of the wind
- Default is 0.001

***** /6000 wind_eps value [#n1e54e56]
- Set lower limit of the energy variation rate.
- When the energy variation rate is under this value, Wind module restarts.
-- energy variation rate = (Previous Wind Energy - Current Wind Energy)/(Current Wind Energy)
- If set 0.0, Wind module never restart by energy variation rate.
- Default is 0.004

***** /6000 region value [#k74c233d]
- Set size of the region
- Normally, the region is automatically set

***** /6000 stop [#ce74eb34]
- Stop the wind
***** /6000 reset [#n4f2b142]
- Stop the wind and reset script
***** /6000 help [#pe008f84]
- Show the help messages
