Searching for actors using foreach

[Erectro]

This seems like some pretty basic functionality, I understand it's slow, it won't be done frequently etc.

I need to search through all my actors to find a bunch of specific ones dynamically and add them to an array list. I'll worry about building the array and adding the found objects once I figure out how to fix this compile error.

My code is the following:

local actor  A;
local string actor_tag;

ForEach WorldInfo.AllActors(class'Actor', A)
{
	actor_tag = A.Tag;
	if (actor_tag == "Crystal")
	{
		P.ClientMessage("crystal found!");
	}
}

The error I'm receiving is:
Error, 'ForEach': An iterator expression is required

On the "ForEach" line obviously.

Cheers

I'm guessing that whatever code you're in doesn't have a WorldInfo reference. Is this in an Actor?

[Erectro]

It's in a UpdateCamera function.

How do I go about adding a reference to WorldInfo?

[Blade[UG]]

so, is that in an Actor, or in an Object? if it's in an Actor, just do foreach AllActors(...) ... if it's in an Object, you could do class'WorldInfo'.static.GetWorldInfo()

AllActors is an iterator defined in Actor. As the camera is an actor, it isn't necessary to use WorldInfo here.

You can also compare Names directly, without having to do a string conversion then comparison.
