[SOLVED]transform of all the childrens in arraylist

Scripting
1

transform of all the childrens in arraylist

in one waypointcontainer there 100 children

arraylist var = waypointcontainer.GetComponentsInChildren(Transform);

i working in c# script and error comes like this expression denotes a ‘type’ where a ‘variable’,'value’or’method group’was expected

but in javascript there no problem if i am using array

plz reply
thanks

arraylist and array are not the same .
try
Transform[ ] var=new Transform[100];
var = (Transform[ ])obj2.GetComponentsInChildren(typeof (Transform));

thanks for the reply it worked but

now i am getting runtime exception

InvalidCastException: Cannot cast from source type to destination type.srr.GetWaypoints () (at Assets\Pro Standard Assets\sss\Scripts\srr.cs:223)
srr.Start () (at Assets\Pro Standard Assets\sss\Scripts\srr.cs:336)

for

potentialWaypoints = (Transform[ ])waypointContainer.GetComponentsInChildren( typeof(Transform ));

NullReferenceException: Object reference not set to an instance of an object

srw.NavigateTowardsWaypoint () (at Assets\Pro Standard Assets\sss\Scripts\srw.cs:82)

for

Vector3 temp=new Vector3( waypoints[currentWaypoint].position.x,transform.position.y,waypoints[currentWaypoint].position.z );

Vector3 RelativeWaypointPosition = transform.InverseTransformPoint(temp);

plz reply

thanks in advance

What does your declaration look like for:

waypointContainer

5

public GameObject waypointContainer;

in inspector i have assign the gameobject also

That looks okay, as a test what happens when you go?

Component[] potentialWaypoints = waypointContainer.GetComponentsInChildren( typeof(Transform ));

Does it give you back a valid list of components?

You cannot do this:

Transform[] potentialWaypoints = (Transform[])waypointContainer.GetComponentsInChildren( typeof(Transform ));

You have to do this:

Component[] potentialWaypoints = (Transform[])waypointContainer.GetComponentsInChildren( typeof(Transform ));

and then when you access the individual potentialWaypoints elements you cast them then:

for (int i = 0; i < potentialWaypoints.Length; i++)
{
     ((Transform)potentialWaypoints[i]).yourpropertyhere;
}

that is pseudo-code.

Was an error in second code block I showed above… here is a working example:

        Component[] transforms = entity.gameObject.GetComponentsInChildren(typeof(Transform));
        for (int i = 0; i < transforms.Length; i++)
        {
            Transform trans = (Transform)transforms[i];

            if (trans.particleEmitter != null)
            {
                trans.particleEmitter.emit = false; 
            }
        }
