#pragma strict help - can't find correct syntax for transform array

Unity Engine
1

Hi all,

I’m trying to get my scripts to be pragma strict, all going fine bar this little bit of code. I can’t seem to figure out the correct syntax for it. I get errors saying the types aren’t covertible.

Anyone know what the correct method?

function OnDrawGizmos () {
	var childrenTransforms : Transform[];
	childrenTransforms = gameObject.GetComponentsInChildren ( Transform ) as Transform;
}
2 
var childrenTransforms = gameObject.GetComponentsInChildren.<Transform>();

Magic, thanks :smile:

Any chance you could elaborate on the difference between (Transform) and .() ?

Bit of a newbie to this, would be good to know for future reference :slight_smile:

Actually I think I understand - the () just returns them as an array of components (i.e. Component[ ] ), where the .<>() returns it as an array of those component types (i.e. Transform[ ] ) ?

Yes, using generics–() rather than (Transform)–casts to the specified type, instead of Component[ ].

That makes sense.

So throughout my scripts where I’ve got nonsense like…

var thisRigidbody : Rigidbody;
thisRigidbody = GetComponent ( Rigidbody ) as Rigidbody;

…to get around pragma strict, I could just use…

var thisRigidbody : Rigidbody;
thisRigidbody = GetComponent.<Rigidbody> ();

…and save myself some messy code?

Yes, though personally I’d further shorten it to

var thisRigidbody = GetComponent.<Rigidbody>();

Yeah, I was just compressing that down for readability. Usually I’d be defining a private var or something that’s been declared outside of the function that the GetComponent’s in.

Thanks, dude, that’s cleared this up for me a lot :slight_smile:

Bumping this for more #pragma strict help.

When writing a custom inspector for my script, it’s throwing errors at me along the lines of;

The code looks like this;

@CustomEditor (worldObject)
class worldObjectEditor extends Editor {
	function OnInspectorGUI () {
		target.objectName = EditorGUILayout.TextField("Object name: ", target.objectName);
	}
}

The script with worldObject.js on it simply has this in it;

var objectName : String = "Default object";

Since the editor assigns the target variable itself… I’m not sure what I can do about it.

Any ways around this?

Huh, it works if I do;

@CustomEditor (worldObject)
class worldObjectEditor extends Editor {
	var targetWO : worldObject;
	function OnInspectorGUI () {
		targetWO = GameObject.Find( target.name ).GetComponent.< worldObject > ();
		targetWO.objectName = EditorGUILayout.TextField("Object name: ", targetWO.objectName);
	}
}

but that seems awkward and hacky to me. I’m not sure it’s the correct way to go about it.

edit;

Think I’ve got it. Seems the easy way to do it is;

@CustomEditor (worldObject)
class worldObjectEditor extends Editor {
	var targetWO : worldObject;
	function OnInspectorGUI () {
		targetWO = target;
		targetWO.objectName = EditorGUILayout.TextField("Object name: ", targetWO.objectName);
	}
}

it’s not complaining at least.

You would cast Object to the appropriate type…instead of “target.objectName”, use “(target as WorldObject).objectName”.

Ah, cheers again, dude :slight_smile:
