For each child variable event

For each child variable (of a structure or array)

For each child variable events give the child variables from structure variables (or arrays) one at a time to their sub-events.

This event stores the value of each child variable (as a string or number) and the name of the child variable (as a string) into variables you specify in the parameters of the event. You can use either scene variables or local variables for the variable to iterate on, for the variable storing the child value, and for the optional variable storing the child name.

Local variables

For Each Child Variable events support local variables. Local variables declared in this event are scoped to the loop: they are initialized before the loop starts and are only accessible within the loop and its sub-events.

Loop counter variable

For Each Child Variable events can have a loop counter variable. When set, this variable starts at 0 and is automatically incremented by 1 for each child variable processed. This is useful to know the index of the current child in the iteration.

To add a loop counter variable, right-click on the For Each Child Variable event and choose Add > Loop Counter Variable.

How to add this event

Right click (or long press) on an existing event and choose "Add" in the menu. Then, select the event you want to add. Alternatively, click on the "Plus" icon in the toolbar or on "Add..." at the bottom of the events sheet.

Example

• Define a structure variable (Fruits) with multiple child variables (Apple, Avocado, Banana)

• Loop through the child objects and change the text to show the name and value of the child object.

• The game preview will now show the correct values.

Tip

The for each object event page explains how to loop on objects one by one.
