The Bring To Operator is similar to the Position
Follow Operator, however this operator "brings" or forces
a particle into a defined position and rotation. The target can be any
position in space, and the alignment can also be derived from any reference
object (a node helper) or absolute value.
IMPORTANT:
The target drag increases exponentially as the number of frames passes.
ON - (Bool) This input data
stream determines whether the operator is considered 'on' or 'off'. You
can connect other operators to this input channel such as a Bool Helper
to activate/deactivate the whole operator.
Time - (Time) This input data stream is used to define the local
time for the operator when the user wants to override the default system
time.
Particle - (Particle) This input data stream reads in the currently
selected particle group that is to be brought to the target. The data
stream MUST be connected and will be highlighted yellow
if it is not.
Position - (Position) This input data stream defines the Bring
To target position. The particle should land on this position (or near
this point).
Alignment - (Alignment) This input data stream tells the particle
how to align as it arrives at this position in space.
Frames - (Frame) This input data stream is used to override the
In Frames spinner value.
Type - (Integer) sets the BringtTo method that should be used,
0 Old Stlye and 1 New Style.
Soft Start - (Scalar) is used to feed in a Soft Start value for
the BringTo effect (see description below).
Smooth Sticking - (Scalar) used to feed in a Smooth Sticking value
for the BringTo effect
Evaluated Frames - outputs
the current (local time) frame that is evaluated by the BringTo effect
Evaluated Relative - outputs the evaluation timing as a value
between 0-1, 0 being the start of the BringTo effect and 1 being the end
of the BringTo effect
In Frames - This spinner sets how long in frames the particles
will take to reach the input position in space. The particles will move
freely less and less as the time (frame) proceeds. Once the particle has
reached the Bring To position and alignment, space warps will no longer
affect them.
Old Style - choose this option to use the "old" BringTo
method as it was introduced in TP 2.5
New Style - when checked, the new BringTo method will be used
(as described below).
Soft Start - defines how
strong the BringTo (drag to the target position) effect should be applied
in the beginning. The bigger this number the less the BringTo effect (drag
to the position) will be present in the starting phase. A value of 0 will
apply the BringTo effect to the particles immediately. Default Value is
1.0
Smooth Sticking - slows down the approach to the target position
(BringTo effect) of the particles. The larger the value the slower the
particles will approach the target positions.
