lindexof in gs2?

[JkWhoSaysNi]

Hello, does lindexof work in GS2? (or have a GS2 equivilent?)

Heres what i'm trying to do:

NPC Code:

---

this.index = lindexof(params[0],this.list);

---

This works:

NPC Code:

---

this.index = lindexof(#v(params[0]),this.list);

---

and so does this:

NPC Code:

---

this.index = lindexof(#p(0),this.list);

---

is there a way to use lindexof using only gscript2?

Thanks.
