Remember and set child materials

[Gibbagobba]

I'm creating an FSM that can be applied to any prefab which sets its material to a colored wireframe based on its tag while storing the original material in a variable. When the wireframe button is pressed again, it sets the material back using this variable.

The main problem I'm facing however, is in applying this to nested objects. For example, I parent all my level geometry to an empty object for organization. This also means I can just apply my FSM to this empty object instead of every individual child. I can also set all of them to the wireframe material using this custom action: http://hutonggames.com/playmakerforum/index.php?topic=6429.msg31357#msg31357

Unfortunately, this also means I can't store every object's material in a single variable and the FSM no longer knows what material(s) to restore and to which objects (making them all pink). How would I go about solving this problem?

Hi.
You might want to look into arrays.
Have 1 array for the objects and 1 array for the materials to "restore" to.
Then loop thru each index from the arrays

I used the Ecosystem action "Get All Recursive Children" to store the child objects in an array. Since one does not already exist that I can tell, I attempted to duplicate and modify the action to recursively get the materials of these children and store them in a second array. The FSM gets stuck on this action so I'm not sure what I should be doing.

Hi. After getting them into an array, you can loop thru the array using 'array get next', get the material and place in another array on the same index.

What command can store each child's material into an array index? None of them accept arrays as variables.

Hi.
Here is how you can do this :
