WhileLoop — loop while condition is true

Macro. WARNING: can cause infinite loop if condition never becomes false.

Loop with no exit condition — will hang the game

Why: Function '{fn}' contains a ForLoop or WhileLoop whose condition is never reached or whose body never updates the counter. The game will freeze when this code runs. Fix: If WhileLoop: ensure the body modifies the condition variable so eventually the condition becomes false. If ForLoop: check the Index range — Last Index must be >= First Index. Add a Print String of the index inside the loop body so you can see if it's actually iterating.

WhileLoop

Runs the loop body as long as the condition stays True. Use carefully — an always-true condition hangs the game.

ForLoop

Runs the loop body a fixed number of times. Exposes the current index pin for use in the body.

ForLoop — loop from FirstIndex to LastIndex

Exec outputs: 'Loop Body' (fires each iteration) and 'Completed' (fires after last iteration).

ForLoop macro pin reference — FirstIndex LastIndex LoopBody Index Completed

Macro from StandardMacros. LastIndex is inclusive (uses <=).

ForEachLoop

Iterates over every element of an array, executing the loop body once per element. Use ForEachLoopWithBreak if you need an early exit.

Delay — wait for Duration seconds then continue

Exec output is 'Completed' (NOT 'then'). Does not block — execution continues after Delay node fires.

DoN — execute N times then stop

ForEachLoopWithBreak — iterate with ability to break early
