Use of the Item.Flag enum in a plugin
Posted 2 years ago
#1

The "Item" class which represents items such as those in the player's inventory has this enum defined in it:

    [Flags]
    public enum Flag
    {
        None = 0,
        Placeholder = 1,
        IsOn = 2,
        OnFire = 4,
        IsLocked = 8,
        Cooking = 16
    }​

It's used for this field in the class:

public Item.Flag flags;

When I try to use the constant Item.Flag.IsOn in a plugin, I get the following error:

Error while compiling SimpleRepro: 'Item' does not contain a definition for 'Flag' and no accessible extension method 'Flag' accepting a first argument of type 'Item' could be found (are you missing a using directive or an assembly reference?) | Line: 9, Pos: 23

Here's the plugin to repro the error:

namespace Oxide.Plugins
{
	[Info("SimpleRepro", "nex", "0.0.0")]
	class SimpleRepro : RustPlugin
	{
		void Init() {
			Puts("Init");
			Item.Flag f = Item.Flag.IsOn;
		}
	}
}
​

Note: There are no "using" statements in this repro.

I even used reflection to see that there is something called "Flag" under "Item", but the compiler error is unexpected. Is it something obvious I'm missing?

Thanks!

Ya should finish looking threw the item code also you need the item you want to set the flag on you cant just use  Item.Flag.IsOn

 public bool HasFlag(Item.Flag f) => (this.flags & f) == f;

  public void SetFlag(Item.Flag f, bool b)
  {
    if (b)
      this.flags |= f;
    else
      this.flags &= ~f;
  }

  public bool IsOn() => this.HasFlag(Item.Flag.IsOn);

  public bool IsOnFire() => this.HasFlag(Item.Flag.OnFire);

  public bool IsCooking() => this.HasFlag(Item.Flag.Cooking);

  public bool IsLocked()
  {
    if (this.HasFlag(Item.Flag.IsLocked))​

So even in the code you pasted, you see it using `Item.Flag.IsOn`. This statement alone is failing to compile for me, with the error I mentioned in the original post. It's almost as if `Item` refers to a different class for me than what we're looking at in the decompiler, but my repro has no "using" statements. This is still a mystery.

Update: I googled around and found some people using `global::Item` instead of `Item`, and this works. Is there some namespace collision on `Item`? What is it colliding with?
