Question by Borzi · Feb 24, 2016 at 03:18 PM · variablegetcomponentcastinggetcomponentsinchildren

Get instances of a script in children

Hello there! I am trying to run a script that allows me to access all instances of a script within the children of an object. To do this, I have tried the following:

 //simplified script to pinpoint the issue
 
 private Component hitBoxes;
 
 void Update()
 //get hitboxes in object
 hitBoxes = GetComponentsInChildren<AIHitbox>();
                 foreach (AIHitbox hitBox in hitBoxes)
                 { //call this function on each instance
                     hitBox.switchForcePos(true);
                 }

Thank you in advance!

You should change private Component hitBoxes; to private Component[] hitBoxes;

GetComponentsInChildren expects to return an array, where as you are trying to assign the result to 'hitBoxes', which is not an array.

Additionally, you are passing the type AIHitbox into the call to GetComponentsInChildren, but assigning it to a hitBoxes, which is a component.

Changing:

private Component hitBoxes;

to

private AIHitbox[] hitBoxes;

should fix your problems
