I don't know if this is possible, I am pulling the names for TitleWindows from my database as strings.
Then from my main application I have to launch the TitleWindow. So in my function I need to convert the name of the TitleWindow which is a String to a Class, because the PopUpManager accepts a Class. Below is my code.
When launching my application and trying to launch the TitleWindow I am getting the error:
Implicit coercion of a value of type String to an unrelated type Class.
I don't want to hard code the name of my popUp in the PopUpManager, that is why I am doing it like this. Any way to work around this?
public function getScreen(screenName:String):void
{
var screen_Name:Class = new Class();
screen_Name = screenName;
var popUpWindow:TitleWindow = PopUpManager.createPopUp(this, screen_Name, false) as TitleWindow;
PopUpManager.centerPopUp(popUpWindow);
}
I have had to do something very similar recently. Here is the function I wrote to do it:
//You have to provice the package signature
private var viewPackage:String = "org.bishop";
//In my case, event.type is the name of a class
var className: String = viewPackage + "." + event.type;
try{
var classRef:Class = getDefinitionByName(className) as Class;
viewNavigator.pushView(classRef);
}
catch(e:ViewError){
trace(e.message);
logger.debug(e.message);
}
Note: for the class to be created correctly, you will need to include both an import statement:
import org.bishop.Login;
and also declare a variable of the class in the code as follows:
Login;
otherwise the classes will not be available to be created.

So this is my code. Im trying to make it so the coins collected add to the score in the UI.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class ScoreTextScript : MonoBehaviour
{
Text.Text
coinAmount;
//Use this for initialization
void Start ()
{
text = GetComponent<Text>();
}
//Update is called once per frame
void Update ()
{
text.Text = coinAmount;
}
}
The Text is the error but I don't know how to fix it.
I need help immediately
I think you don't understand how variables work in unity.
First you are declaring a Text.text called coinAmount
In Unity when you are declaring a variable you first have to set the access modifier.
The 2 main are: private and public.
private means your variable will only be accessible in the class you declared it.
public means you can access it from any other class if you make a reference to that script.
Then you need to put the type of your variable.
Here you used Text.text and that's not a type for a variable.
You can set to int, string, etc... If you want to use a Text component in unity do like this:
private Text coinAmount;
Since it's a private variable you can't drag it in the editor. If you want to be able to place a Text component by hand in the editor you can either do:
public Text coinAmount;
//or
[SerializeField] private Text coinAmount; //I'll let you search about SerializeField
In your Start method you are assigning text variable to the Text component this object hold. But text does not exist. If you declare a variable in a method it will only be accessible in this method.
So, what you want is:
private void Start(){
coinAmount = GetComponent<Text>();
}
And lastly i see you want to assign your text to the variable we created earlier. That's useless. You need to create a new variable of type int and assign it to the text value of coinAmount.
To do so:
We will create a new variable right under coinAmount.
public int coinNumber;
And in update we can use it:
private void Update(){
coinAmount.text = coinNumber.ToString(); //.ToString() is used when you want to convert something to a string (which is a type of variable).
}
And there we go everything should work correctly !
The whole code:
private Text coinAmount;
public int coinNumber;
private void Start(){
coinAmount = GetComponent<Text>();
}
private void Update(){
coinAmount.text = coinNumber.ToString(); //.ToString() is used when you want to convert something to a string (which is a type of variable).
}
Hope it helped ! Have a nice day !
I have a method called changePlaceName and i know it is working but after i call getPlaces to see the changes, i don't see the new place name instead i see the name when i created a new place.
this is changePlaceName
export function changePlaceName(placeId: u32, placeName: PlaceName): void {
assert(placeId >= 0, 'Place ID must be >= 0');
const place = Place.find(placeId);
logging.log(place.name); //gives "Galata Tower"
place.name = placeName;
logging.log(place.name); // gives "New Galata Tower"
}
I need to save it somehow but I don't know how to do it.
I also tried this way;
export function changePlaceName(placeId: u32, placeName: string): void {
assert(placeId >= 0, 'Place ID must be >= 0');
const place = Place.find(placeId);
logging.log(place.name);
place.name = placeName;
let newPlace = storage.get<string>(placeName, 'new galata tower');
storage.set<string>(placeName, newPlace);
logging.log('New place is now: ' + newPlace);
}
Now my visual code is complaining about the newPlace inside the storage.set
How do I fix it?
What is the code of Place.find? I assume you are using a persistent map under the hood.
Is there a Place.set? You need to store the Place back to the same key used to find it.
because you're using some kind of class to manage the concept of "Place", why not add an instance method to that class to save() the place once you've changed it's name?
would help if you also posted your code for Place here, by the way
my guess is that it looks something like this?
!note: this is untested code
#nearBindgen
class Place {
private id: number | null
private name: string
static find (placeId: number): Place {
// todo: add some validation for placeId here
const place = places[placeId]
place.id = placeId
return place
}
// here is the instance method that can save this class
save(): bool {
places[this.id] = this
}
}
// a collection of places where placeId is the index
const places = new PersistentVector<Place>("p")
I have followed the pattern from examples on GitHub. When I call store on the model object, passing an instance of the entity, I get a compile error indicating one of the implicit parameters is missing as shown below.
could not find implicit value for parameter sg: com.outworkers.phantom.macros.SingleGeneric.Aux[com.ss.wuhu.settlement.entity.Settlement,Repr,HL,Out]
I guess I am missing something obvious. Could someone please point out how to bring the implicit into scope?

This is the code snippet where I am storing the data.
import akka.Done
import com.outworkers.phantom.dsl._
import com.outworkers.phantom.connectors.{CassandraConnection, ContactPoints}
import com.ss.wuhu.settlement.entity.Settlement
import com.ss.wuhu.settlement.entity.mapping.{SettlementForCourierModel, SettlementForVendorModel}
object Connector {
private val hosts = Seq("127.0.0.1") // TODO from environment
lazy val connector: CassandraConnection = ContactPoints(hosts).keySpace("wuhu_order")
}
class SettlementDatabase(override val connector: CassandraConnection) extends Database[SettlementDatabase](connector) {
object SettlementForCourierModel extends SettlementForCourierModel with connector.Connector
object SettlementForVendorModel extends SettlementForVendorModel with connector.Connector
def truncateAll() = {
Database.truncate()
}
def store(set: Settlement) = {
for {
v <- Database.SettlementForVendorModel.store(set)
d <- Database.SettlementForCourierModel.store(set)
} yield (Done)
}
}
object Database extends SettlementDatabase(Connector.connector)
This is a known bug with an open issue: https://github.com/outworkers/phantom/issues/774
I suggest either using the workaround as described in the link above, or my workaround which was creating my own .store() using .insert().
example:
def myStore(person: Person) : Future[ResultSet] =
insert
.value(_.name, person.name)
.value(_.age, person.age)
.value(_.timeCreate, person.timeCreate)
.future()
I have a simple Scala class called Case
case class Case(
#(Id#field) var id: String,
var state: CaseState = new OpenCaseState,
var notes: List[CaseNote] = new ArrayList(),
var assignedGroups:Set[String] = new HashSet(),
var aclTemplateIds: Set[String] = new HashSet()
) extends Serializable { }
I created an instance of this class called a_case, setting id as 123. I am trying to get the value of the id attribute. I tried this
var parser: ExpressionParser = new SpelExpressionParser
var context: EvaluationContext = new StandardEvaluationContext(a_case)
var extractedId = parser.parseExpression("'id'").getValue(context).asInstanceOf[String]
All I get is "id" in my extractedId variable. When I try to parse "id" without the single quotes, I get an exception saying the property id is not found in Case. Am I missing something here or is this a Scala issue?
SpEL can do that for you if your id has getter.
I'm not well with Scala, but:
BeanProperty
You can annotate vals and vars with the #BeanProperty annotation. This generates getters/setters that look like POJO getter/setter definitions. If you want the isFoo variant, use the BooleanBeanProperty annotation. The ugly foo$_eq becomes
setFoo("newfoo");
getFoo();

In my PHP Extension (Written in C) I have a string with the class name. To be more precise, I have the namespace + class name. For example: Dumb\Factory
This class implements an interface defined in my extension which has a class entry
zend_class_entry *garlic_servicemanager_factoryinterface_ce;
and implements a public method named createService
Inside another class I have a method named get and I check to see if the parameter is a string. When it is a String I would like to instantiate the class and call that method, however I don't know how to instantiate the PHP class from within my C code.
How may I instantiate a class from a string so I can call the method defined by the interface?
You have to find the class_entry from the string and you can do it like below...
zend_class_entry *ce = NULL;
char *className = "Dumb\Factory";
zend_class_entry **pce;
if (zend_lookup_class(className, strlen(className ), &pce TSRMLS_CC) == FAILURE) {
zend_throw_exception_ex(NULL, 0 TSRMLS_CC, "Class %s does not exist", className);
return;
}
ce = *pce;
// Now you have got "zend_class_entry" and
// now you can create N number of objects out of it.
// Check the Reflection API for more info.
