i pasted this code into update function
code

 while (b.method("MoveNext").invoke()) {
                let pos: Il2Cpp.Object = b.method("get_Current").invoke().method("get_MechHeadTransform").invoke().method("get_position").invoke(); //

                let screenpoint = this.field("gunCamera").value.method("WorldToScreenPoint", 1).overload("UnityEngine.Vector3").invoke(pos);
                //jlog(asc.class("SupportAimController").method("get_CenterOfScreen").invoke().type)
