mTargetAlpha
F32 = 0.5 The fade value to reach. Shipped events mostly use 0 to fade the unit out and 1
to fade it in.
An animation event that fades the unit. When the event
starts, the unit's fade value starts to move to mTargetAlpha, and reaches it after
mTimeToFade.
The event does its work once, at the start. It does nothing when it ends or when the clip stops, so the unit stays at the target value. An animation that fades the unit out must fade it in again with another event.
F32 = 0.5 The fade value to reach. Shipped events mostly use 0 to fade the unit out and 1
to fade it in.
F32 = 0 The time the fade takes, in seconds. 0 sets the target value at once.
