Note
This is a web-version of a tutorial chapter embedded right into the XOD IDE.
To get a better learning experience we recommend to install the
desktop IDE or start the
browser-based IDE, and you’ll see the same tutorial there.
Branching
Choosing between values based on some condition is a common task. For this, there is an if-else node in xod/core.
The COND pin of this node checks the boolean input value. If COND receives true, the node sets the value from the T pin to the R pin. When it receives false, it sets the value from the F pin to the R pin.
Exercise #
Learn how if-else behaves.
- Run the simulation.
- Change the value of the
tweak-booleannode, observe howif-elseoutput chenges. - Replace
tweak-booleanwith aflop-flopwithTGLpin connected to aclock.
