Set Attribute
|
The Set Attribute block sets the value of an attribute to the block's input data
value. Specify the object whose attribute you would like to set by connecting the
Set Attribute block's action link to it. You can connect the action link to any G2
object or block. Specify the attribute you would like to set by setting Target
Attribute to its name.
When you connect a block to the Set Attribute block's action link, the configuration panel displays a list of all attributes defined by the connected block. Thus,
you should always connect the Action Link to the target before configuring the
block.
Take the following precautions when using the Set Attribute block:
Caution: When you use the Set Attribute block, be sure that the changes to the
attribute value leave the target block in a valid state; otherwise, errors will
result. For example, if you use the Set Attribute block to set the Upper
Threshold of an observation block to a number that is less than the Lower
Threshold, you will receive a warning and a runtime error might result.
