Collider does not contain enabled?

Unity Engine
1

I get this message:

Type UnityEngine.Collider' does not contain a definition for enabled’ and no extension method enabled' of type UnityEngine.Collider’ could be found (are you missing a using directive or an assembly reference?)

But I see “enabled” here:

What am I missing? Shouldn’t I be able to set it? The link here: Unity - Scripting API: Collider.enabled even shows me how to do it, but it won’t let me…

CODE

public void OnTriggerEnter(Collider other)
{
// Do no collide with yourself
if (other.name == transform.parent.name)
return;
// Snap to the X of this box
Vector3 tmpPos = other.transform.position;
tmpPos.x = transform.position.x;
tmpPos.x = 0; print(tmpPos + " " + other.transform.position);
other.enabled = false;
other.transform.position = tmpPos;
print(other.name);
}

Any help you can give would be great. Thanks in advance.

Are you sure you using Unity 3.4 or higher? This was only introduced in Unity 3.4

I’m using 3.3… that would explain it.

Thank you!
