Flow

Flow nodes answer one question: where can execution go next? They turn braces and keywords into named paths you can follow from the entry node to a return, throw, or normal end.

Pick the shape

• Branch: choose true or false, including chained else if paths.
• Loops: repeat with for, foreach, while, or do-while, and understand break and continue.
• Switch: send one value to cases or expression arms, including defaults and goto case.
• Try, catch, and using: show exception handlers, filters, cleanup, and resource scopes.
• Return and throw: finish a method normally, leave early, or terminate with an exception.

A useful tracing rule

Follow one exec output at a time. On a branch, choose true or false. On a loop, follow loop body once, then jump to completed. On a switch, pick one arm. This gives you a readable story before you inspect every alternative.

The Platformer examples in these guides are ordinary C# methods parsed into node graphs. The C# remains authoritative, and Compile writes visual drafts back into those same method bodies.

Next

• Branch: start with the most common decision.
• Loops: trace repeated work without getting trapped in the cycle.
• Return and throw: learn where paths stop.
