I need help on how to show a scoreboard under players name that shows their health. The problem is that I can't see it. Here is the code:
#EventHandler
public void PlayerJoin(PlayerJoinEvent e) {
final Player p = e.getPlayer();
ScoreboardManager manager = Bukkit.getScoreboardManager();
final Scoreboard board = manager.getNewScoreboard();
final Objective objective = board.registerNewObjective("showhealth", Criterias.HEALTH);
objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
objective.setDisplayName(ChatColor.RED + "❤");
p.setScoreboard(board);
p.setHealth(p.getHealth());
}
Can someone help me? Thanks in advance.
Remember to register the event.
Use Bukkit.getServer().getPluginManager().registerEvents(listener,plugin); at onEnable()
#Override
public void onEnable() {
Bukkit.getServer().getPluginManager().registerEvents(new Listener(),this);
}
Instead of new Listener() could also be this if your EventHandler is also at the main class
I also recommend you to use a later BukkiRunnable onPlayerJoin to leave the system register correctly the player.

im pretty new to the mirror package and im trying to build a simple multiplayer game thats basically played using UI elements only (buttons). A big part of the game is announcements that show up like - "Player X's Turn" for example.
At the moment the announcement only shows up in the host game, if the announcement came from the Networkbehaviour class that belongs to the player it would be easy to solve with a simple ClientRPC function but i want the UI functions to run from a different class that handles the UI elements.
what is the correct way to implement this? does the UIHandler need to be inhereting from any network class? would love some tips regarding this subject.
thanks in advance,
Amit Wolf.
A common strategy is to build a singleton networked event manager that triggers the RPC as an event.
public class EventManager: NetworkBehaviour
{
public static EventManager Instance;
void Awake()
{
if(Instance == null)
Instance = this;
else
Destroy(this);
}
public event Action<int> OnPlayerTurnChanged;
[ClientRpc]
public void ChangeTurn(int playerId)
{
OnPlayerTurnChanged?.Invoke(playerId);
}
}
Then you can subscribe to the event in any other script and perform logic:
public class UIScript: NetworkBehaviour
{
void Awake()
{
EventManager.Instance.OnPlayerTurnChanged+= UpdateUI;
timer = 0f;
}
void UpdateUI(int playerId)
{
//UI Logic to set the UI for the proper player
}
}
How to change Vuforia the AnchorInputListenerBehaviour, the original setting is clicked on the screen, I want to change it to judge the Micro Switch high or low signal?
You don't need the Vuforia code at all!
You seem to rather just want to have your own custom UnityEvent in the Inspector you can invoke whenever you want to ;)
If you need it you can even extend this and add some parameters as described here using UnityEvent<T> e.g. something like
[Serializable]
public class CustomEvent : UnityEvent<bool> { }
public class Example : MonoBehaviour
{
public CustomEvent _onButtonStateChanged;
private bool lastState;
// Now however you check your button states and get your pin data
// on whatever condition you can simply invoke your event
private void Update()
{
//TODO
var currentState = GetYourButtonStateByMagic();
if(currentState != lastState)
{
_onButtonStateChanged.Invoke(currentState);
lastState = currentState;
}
}
}
In the new Unity3D UI (Unity > 4.6), I'm trying to create a simple script I can attach to a UI component (Image, Text, etc) that will allow me to wedge in a custom tooltip handler. So what I need is to capture a PointerEnter and PointerExit on my component. So far I'm doing the following with no success. I'm seeing the EVentTrigger component show up but can't get my delegates to fire to save my life.
Any ideas?
public class TooltipTrigger : MonoBehaviour {
public string value;
void Start() {
EventTrigger et = this.gameObject.GetComponent<EventTrigger>();
if (et == null)
et = this.gameObject.AddComponent<EventTrigger>();
EventTrigger.Entry entry;
UnityAction<BaseEventData> call;
entry = new EventTrigger.Entry();
entry.eventID = EventTriggerType.PointerEnter;
call = new UnityAction<BaseEventData>(pointerEnter);
entry.callback = new EventTrigger.TriggerEvent();
entry.callback.AddListener(call);
et.delegates.Add(entry);
entry = new EventTrigger.Entry();
entry.eventID = EventTriggerType.PointerExit;
call = new UnityAction<BaseEventData>(pointerExit);
entry.callback = new EventTrigger.TriggerEvent();
entry.callback.AddListener(call);
et.delegates.Add(entry);
}
private void pointerEnter(BaseEventData eventData) {
print("pointer enter");
}
private void pointerExit(BaseEventData eventData) {
print("pointer exit");
}
}
Also... the other method I can find when poking around the forums and documentations is to add event handlers via interface implementations such as:
public class TooltipTrigger : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler {
public string value;
public void OnPointerEnter(PointerEventData data) {
Debug.Log("Enter!");
}
public void OnPointerExit(PointerEventData data) {
Debug.Log("Exit!");
}
}
Neither of these methods seems to be working for me.
Second method (implementation of IPointerEnterHandler and IPointerExitHandler interfaces) is what you're looking for. But to trigger OnPointerEnter and OnPointerExit methods your scene must contain GameObject named "EventSystem" with EventSystem-component (this GameObject created automatically when you add any UI-element to the scene, and if its not here - create it by yourself) and components for different input methods (such as StandaloneInputModule and TouchInputModule).
Also Canvas (your button's root object with Canvas component) must have GraphicRaycaster component to be able to detect UI-elements by raycasting into them.
I just tested code from your post and its works just fine.
after hours of searching and trying, I decided to ask here.
JqmHeader.java
public class JqmHeader extends ComplexPanel {
public JqmHeader() {
setElement(DOM.createDiv());
getElement().setAttribute("data-role", "header");
}
public void add(Widget widget) {
super.add(widget, getElement());
}
}
JqmPage.java
public class JqmPage extends ComplexPanel {
...
public JqmPage(String id) {
setElement(Document.get().createDivElement());
getElement().setAttribute("data-role", "page");
getElement().setAttribute("data-url", id);
RootPanel.get().add(page);
render(page.getId());
}
private native void render(String id) /*-{
$wnd.$("#" + id).page();
}-*/;
...
}
MyPage.java extends JqmPage.java
...
JqmHeader header = new JqmHeader();
Button b = new Button("TestButton");
b.addClickHandler(new ClickHandler() {
#Override
public void onClick(ClickEvent event) {
Window.alert("TestButton clicked");
}
});
header.add(b);
this.add(header);
...
My Problem
So, my Problem is, that the ClickHandler from the Button in the header bar doesn't fire. If I add the Button not to the header, but to the "RootPage", like
this.add(b)
, everything works.
I think it must lie at the jquery-mobile header implementation. Are there any workarounds /ideas?
Thanks from Berlin,
Alex
JQuery Mobile swallows the events on headers so they are not propagated to GWT. What I did in solving this for jqm4gwt (https://github.com/sksamuel/jqm4gwt) was to have a general listener on the page level and then compare event source. If it was a button in the header then I fire that event on the button manually.
Take a look at bindHeaderEvents in https://github.com/sksamuel/jqm4gwt/blob/master/src/main/java/com/sksamuel/jqm4gwt/JQMPage.java
Also, the jqm4gwt project might be a good solution for you to save you having to invent all these widgets yourself.
If you want to take a look at a pure GWT solution for building mobile apps you could take a look at http://www.m-gwt.com
I am currently developing a paint-like application for GWT. I would like to add a mouse handler that runs when the user drags the mouse across the canvas(like making a square,etc;), the problem is that I'm not surewhat handler to use. Looking through the handlers implemented in canvas has lead me to some hints, but the documentation as to what event the apply to is scant.
Does anyone know how I should implement it? Thanks.
There is no "dragging" handler. You imlement "dragging" with MouseDown, MouseMove and MouseUp events.
class YourWidget extends Composite
{
#UiField
Canvas yourCanvas;
private boolean dragging;
private HandlerRegistration mouseMove;
#UiHandler("yourCanvas")
void onMouseDown(MouseDownEvent e) {
dragging = true;
// do other stuff related to starting of "dragging"
mouseMove = yourCanvas.addMouseMoveHandler(new MouseMoveHandler(){
public void onMouseMove(MouseMoveEvent e) {
// ...do stuff that you need when "dragging"
}
});
}
#UiHandler("yourCanvas")
void onMouseUp(MouseUpEvent e) {
if (dragging){
// do other stuff related to stopping of "dragging"
dragging = false;
mouseMove.remove(); // in earlier versions of GWT
//mouseMove.removeHandler(); //in later versions of GWT
}
}
}
I've messed around with this as well and produced this little thing awhile ago:
http://alpha2.colorboxthing.appspot.com/#/
I basically wrapped whatever I needed with a FocusPanel. In my case it was a FlowPanel.
From that program in my UiBinder:
<g:FocusPanel ui:field="boxFocus" styleName="{style.boxFocus}">
<g:FlowPanel ui:field="boxPanel" styleName="{style.boxFocus}"></g:FlowPanel>
</g:FocusPanel>
How I use the focus panel (display.getBoxFocus() seen below just gets the FocusPanel above):
display.getBoxFocus().addClickHandler(new ClickHandler() {
#Override
public void onClick(ClickEvent event) {
}
});
display.getBoxFocus().addMouseDownHandler(new MouseDownHandler() {
#Override
public void onMouseDown(MouseDownEvent event) {
}
});
display.getBoxFocus().addMouseMoveHandler(new MouseMoveHandler() {
#Override
public void onMouseMove(MouseMoveEvent event) {
}
});
display.getBoxFocus().addMouseUpHandler(new MouseUpHandler() {
#Override
public void onMouseUp(MouseUpEvent event) {
}
});
// etc!
To answer your question about what handler to use for "dragging" I haven't found a single handler to do that for me. Instead I used a MouseDownHandler, MouseMoveHandler, and a MouseUpHandler.
Use the MouseDownHandler to set a flag that determines when the users mouse is down. I do this so that when MouseMoveHandler is called it knows if it should do anything or not. Finally use MouseUpHandler to toggle that flag if the user has the mouse down or not.
There have been some flaws with this method (if the user drags their mouse off of the FocusPanel), but because my application was just a fun side project I haven't concerned myself with it too much. Add in other handlers to fix that if it becomes a big issue.
