I want to put one of these into a program I am writing but for the life of me I cannot remember what it is called (or where it is located in the panel).
I drew it from memory in MS Paint and how it is wired, though I cannot remember if it sends a boolean true/false or if it sends the value.
It stores a value in memory from the control it is wired to. If the value doesn't change, it doesn't do anything (or sends a false constant). If the value does change, it sends the new value (or a true constant).
On second thought I am pretty sure it sends boolean values, though I don't see it in the boolean tab.
Solved! Go to Solution.
If you're refering to the "arrow" it could be a feedback node..functions>programming>structures
If the value doesn't change, it doesn't do anything (or sends a false constant). If the value does change, it sends the new value (or a true constant).
A feedback node does not do that alone. You need additional code, for example a "not equal". (there is also an openg tool)
Here's simple demo. (The LED will light up for one iteration whenever the numeric changes its value.)
