Data Instance
In the Logic Drawer
This tool has no fixed inputs or outputs, but it provides a variety of inputs and outputs that vary, depending
on the data type selected. Each data type has a specific set of data elements that can be accessed. You can use
the Data Instance tool to access these data elements individually then link them into other tools.
For instance, the Point data type contains the x and y coordinates of a point in the format of (x, y). If you
select this data type in the Data Instance tool, the x and y coordinates are provided individually as Real data
types on the outputs of the Data Instance tool. These Real values can then be linked individually into another
tool, or displayed on a control panel.
Data Set
In the Logic Drawer
7 7 False Count + Increment
Count = Limit so Success set to False
8 8 False Count + Increment
9 9 False Count + Increment
10 0 True Count + Increment
Count = Rollover so Count set to Reset Value
Count < Limit so Success set to True
Input Name What it is
Count The current Count
Reset Value When the Count value equals the Rollover value, the Count value is set
to the Reset value and the Success output is set to True.
Rollover Value When the Count value reaches this value, the Count value is set equal to
the Reset value.
If the Increment value is negative, this value must also be negative and
less than the initial Count value.
Increment The Count value is increased (or decreased) by this amount each time
the tool runs.
If this value is negative, the Rollover value must also be negative.
Limit When the Count value equals the Limit value, the Success output is set
to False. If the Increment value is negative, this value should be negative
also.
Output Name What it is
Success When the Count value equals the Rollover value, this output is set to
True. When the Count value equals the Limit value, this output is set to
False.
