setScale() doesn't work either.
I was going to flip the camera for when something interesting happens, but I don't how how.
You could flip the camera (and apply other interesting effects) with shaders!
FlxCamera has a function called setFilters() that allows you to add a list of bitmap filters to an active camera.
Here's a simple filter I wrote that flips all textures horizontally:
import openfl.filters.ShaderFilter;
var filters:Array<BitmapFilter> = [];
// Add a filter that flips everything horizontally
var filter = new ShaderFilter(new FlipXAxis());
filters.push(filter);
// Apply filters to camera
FlxG.camera.setFilters(filters);
And in a separate class called FlipXAxis:
import flixel.system.FlxAssets.FlxShader;
class FlipXAxis extends FlxShader
{
#:glFragmentSource('
#pragma header
void main()
{
vec2 uv = vec2(1.0 - openfl_TextureCoordv.x, openfl_TextureCoordv.y);
gl_FragColor = texture2D(bitmap, uv);
}')
public function new()
{
super();
}
}

I'm trying to write a plugin to brand cattle and thought it would be pretty easy, but I'm stuck looking for the information that would help me do this.
Where can I find information that will help me map a texture (from a png, for example) onto an Entity. While there's information about built-in textures for Players etc, I haven't found a resource that would help me understand how I could get something to render on the side of an Entity.
I'm guessing that I'd use something like the following calls...
Minecraft.getMinecraft().renderEngine.bindTexture(new ResourceLocation("tc:textures/gui/my-icon.png"));
Minecraft.getMinecraft().ingameGUI.drawTexturedModalRect(etc);
Not certain how I'd enforce them into the drawing of a cow or a horse.
This isn't possible while using Bukkit, since Bukkit is server-side and can't change textures. There's one exception, though: Servers can send players resource packs. However, there does not appear to be a way to create a unique texture based off of any data, so you'd have to make all cows look the same. It wouldn't really do what you want. (Players are another exception, but protocol-wise, their skins are arbitrary anyways).
However, if you want to use Minecraft Forge, this is far more manageable. You can subclass the entity and change some of the rendering code. Perhaps you can also have an item of some sort (a branding iron, maybe) to convert existing cows into branded cows (they would still spawn as normal cows). I'm not too much of a Forge dev, but something like this should work (though I haven't tested it). This is more of an outline; things like converting the entity and creating an item I'll leave to you.
Here's a basic outline for an entitiy that tracks a texture between the server and the client:
import net.minecraft.entity.passive.EntityCow;
import net.minecraft.util.ResourceLocation;
public class EntityBrandedCow extends EntityCow {
#Override
protected void entityInit() {
super.entityInit();
// Data watcher lets you track data between the server and client
// without handling packets yourself
// http://wiki.vg/Entities
this.dataWatcher.addObject(14, "minecraft:textures/entity/cow/cow.png");
}
public void setTexture(ResourceLocation texture) {
this.dataWatcher.updateObject(14, texture.toString());
}
public ResourceLocation getTexture() {
return new ResourceLocation(this.dataWatcher.getWatchableObjectString(14));
}
}
You'll need to register a custom renderer for your new entity. This would go in the client proxy.
RenderingRegistry.registerEntityRenderingHandler(EntityBrandedCow.class, new RenderBrandedCow(Minecraft.getRenderManager(), new ModelCow(), .7f));
And here's such a render you can use:
import net.minecraft.util.ResourceLocation;
import net.minecraft.client.model.ModelBase;
import net.minecraft.entity.Entity;
import net.minecraft.client.model.ModelBase;
import net.minecraft.client.renderer.entity.RenderLiving;
import net.minecraft.client.renderer.entity.RenderManager;
public class RenderBrandedCow extends RenderLiving {
public RenderBrandedCow(RenderManager manager, ModelBase model, float shadowSize) {
super(manager, model, shadowSize);
}
#Override
protected ResourceLocation getEntityTexture(Entity entity) {
return ((EntityBrandedCow)entity).getTexture();
}
}
That renderer only changes the texture, and doesn't actually overlay anything. This, among other things, means that texture packs won't change branded cows without creating additional textures. An alternative would be to create a second layer. (This is based off of the way sheep wool works - see net.minecraft.client.renderer.entity.layers.LayerSheepWool and net.minecraft.client.renderer.RenderSheep). You can change the renderer to this:
import net.minecraft.client.model.ModelBase;
import net.minecraft.client.renderer.entity.RenderLiving;
import net.minecraft.client.renderer.entity.RenderManager;
public class RenderBrandedCow extends RenderCow {
public RenderBrandedCow(RenderManager manager, ModelBase model, float shadowSize) {
super(manager, model, shadowSize);
this.addLayer(new LayerCowBrand(this));
}
}
And here's the start of some kind of layer rendering code. This won't work on its own; you'll need to write a ModelBrand (see ModelSheep1 for the basis of that).
public class LayerCowBrand implements LayerRenderer {
private final BrandedCowRenderer renderer;
private final ModelBrand model = new ModelBrand();
public LayerCowBrand(BrandedCowRenderer renderer) {
this.renderer = renderer;
}
public void doRenderLayer(EntityBrandedCow entity, float p_177162_2_, float p_177162_3_, float p_177162_4_, float p_177162_5_, float p_177162_6_, float p_177162_7_, float p_177162_8_) {
// It's common to write a second method with the right parameters...
// I don't know off my hand what the parameters here are.
this.renderer.bindTexture(entity.getTexture());
this.model.setModelAttributes(this.sheepRenderer.getMainModel());
this.model.setLivingAnimations(p_177162_1_, p_177162_2_, p_177162_3_, p_177162_4_);
this.model.render(p_177162_1_, p_177162_2_, p_177162_3_, p_177162_5_, p_177162_6_, p_177162_7_, p_177162_8_);
}
public boolean shouldCombineTextures() {
// I don't know
return true;
}
public void doRenderLayer(EntityLivingBase p_177141_1_, float p_177141_2_, float p_177141_3_, float p_177141_4_, float p_177141_5_, float p_177141_6_, float p_177141_7_, float p_177141_8_) {
// This is the actual render method that implements the interface.
this.doRenderLayer((EntityBrandedCow)p_177141_1_, p_177141_2_, p_177141_3_, p_177141_4_, p_177141_5_, p_177141_6_, p_177141_7_, p_177141_8_);
}
}
Hopefully this at least lets you get started. As I said, I'm not a forge dev, but this should be the basics. If you want to ask more questions about forge, post here on Stack Overflow using minecraft-forge (Gaming Stack Exchange also has a minecraft-forge tag but that's for mod usage, not development).
Could you please advise how i would go about using the input touch function in Unity to make an object changes its x direction every time the user tap on the screen. For example, for 2d setting game, an object is moving forward (to the right) in the x position, if the user tap then the object would move backward in the x position (to the left). Sorry no code is produced.
It's simple as your name "tony" :)
What you can do is to make a simple script which'd move your object to left and right. And on screen touch you can easily change its direction by just -1 multiplication.
Simple script that you can attach to your object.
using UnityEngine;
using System.Collections;
public class MoveObject : MonoBehaviour
{
float _limit = 5;
// 1 for right and -1 for left.
float _direction = 1;
// You can call it as speed
float _speed = 0.01f;
void Start ()
{
}
void Update ()
{
transform.position = Vector3.MoveTowards (transform.position, new Vector3 (transform.position.x + _direction, transform.position.y, transform.position.z), _speed);
if (Input.GetMouseButtonDown (0))
_direction *= -1;
}
}
Hope this helps :)
I am having a class inherited from QGraphicsScene. I have a mouseMoveEvent in this class. Based on the mouse move I am sending the co ordinates via signal to the main window. I have multiple GraphicViews in main window. Based on the scene from which the signal is received I am display the scene co ordinates using QGraphicsTextItem.
The problem is when I move out of the scene area I am unable to hide the QGraphicsTextItem.
Can someone give me a work around for this?
Class Scene::QGraphicsScene
{
void MouseMoveEvent(QGraphicsSceneMouseEvent *Event)
{
int XPos = event.x();
int YPos = event.y();
emit SignalPos(XPos,YPos);
}
}
//In Main Window
connect(scene1,SignalPos(int,int),this,SlotPos1(int,int);
//Similarly for scene2,scene3,scene4
void MainWindow::SlotPos(int X, int Y)
{
m_qgtxtItemX.setText(QString::x);
//I want to hide this once I am out of scene.It is a member variable. I tried
//taking local variable but it didn't work.
//Similarly for y and other slots
}
Install an event filter on the scene.
scene1->installEventFilter(this);
then implement the method in the class that is referenced by "this":
bool eventFilter(QObject *watched, QEvent *event) {
if (event->type() == QEvent::Leave)
{
qDebug() << "Mouse left the scene";
}
return false;
}
Just tried it and it worked! If you are installing the event filter on more than one object, please use "watched" to differentiate between them.
Best,
I just started to learn Javafx, and I really like it so far. However in my current project I would need to use text as the tick labels for the javafx slider. I googled it a lot, but couldn't find any help. So for example I would like a slider with 4-5 positions, and them being "bad", "good", etc. instead of 1,2,3,...
I know I could build a custom UI manually with labels placed at the correct places, but I need to generate the sliders with custom text, and diofferent length every time, so it wouldn't work. In swing it is possible to change the labels with a hashtable for example, so my question is, is it possible to do it in Javafx?
Here is a sample using slider.setLabelFormatter.
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Slider;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
import javafx.util.StringConverter;
public class SlidingScale extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
Slider slider = new Slider(0, 3, 0);
slider.setMin(0);
slider.setMax(3);
slider.setValue(1);
slider.setMinorTickCount(0);
slider.setMajorTickUnit(1);
slider.setSnapToTicks(true);
slider.setShowTickMarks(true);
slider.setShowTickLabels(true);
slider.setLabelFormatter(new StringConverter<Double>() {
#Override
public String toString(Double n) {
if (n < 0.5) return "Novice";
if (n < 1.5) return "Intermediate";
if (n < 2.5) return "Advanced";
return "Expert";
}
#Override
public Double fromString(String s) {
switch (s) {
case "Novice":
return 0d;
case "Intermediate":
return 1d;
case "Advanced":
return 2d;
case "Expert":
return 3d;
default:
return 3d;
}
}
});
slider.setMinWidth(380);
HBox layout = new HBox(slider);
layout.setPadding(new Insets(30));
primaryStage.setScene(new Scene(layout));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
The sample above only works in Java 8 due to a bug in JavaFX 2.2.
Some of the labels disappear as you make the the slider smaller, so I set a min width on the slider so that the labels remain (an alternate solution, might be to set a new label formatter with abbreviated labels used if the slider is sized small).
You might also be interested in voting for or commenting on the following feature request: RT-27863 A LabelFormatter isn't enough to customize Slider ticks.
I'm at a loss here. I've got a simple terrain generation algorithm working, and I've got some simple keyboard navigation working by extending ViewPlatformAWTBehavior and handling my own events. That's all well and good, and I can follow terrain. Hooray!
What I'd like to do is get some simple "mouse look" working. MouseRotate is close, but I'm looking for something more like an FPS ... where you aren't going to roll the camera, you're limited to 90 degrees vertical (up or down), and the mouse cursor is captured by the JFrame (with an escape).
I just can't seem to get it to work. I can capture the mouse event just fine, and mouseMoved works. I could probably just use an invisible cursor, and that would get me a large part of the way there (maybe), but I'd be stuck when trying to keep the mouse in the screen ... as soon as you're out of the frame, the mouse would be visible and stop rotating the view.
I keep thinking I must be going about this wrong, because this has to be a fairly common implementation, but I can't find anything on it.
Does anyone have some pointers or references?
If you want this is the code to make a full screen window which will help you with mouse problems
package fullscreen;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class FullScreen extends JFrame{
private JPanel contentPane = new JPanel();
private JButton fullscreenButton = new JButton("Fullscreen Mode");
private boolean Am_I_In_FullScreen = false;
private int PrevX,PrevY,PrevWidth,PrevHeight;
public static void main(String[] args) {
FullScreen frame = new FullScreen();
frame.setSize(600,500);
frame.setVisible(true);
}
public FullScreen(){
super("My FullscreenJFrame");
setContentPane(contentPane);
//From Here starts the trick
FullScreenEffect effect = new FullScreenEffect();
fullscreenButton.addActionListener(effect);
contentPane.add(fullscreenButton);
fullscreenButton.setVisible(true);
}
private class FullScreenEffect implements ActionListener{
#Override
public void actionPerformed(ActionEvent arg0) {
if(Am_I_In_FullScreen == false){
PrevX = getX();
PrevY = getY();
PrevWidth = getWidth();
PrevHeight = getHeight();
dispose(); //Destroys the whole JFrame but keeps organized every Component
//Needed if you want to use Undecorated JFrame
//dispose() is the reason that this trick doesn't work with videos
setUndecorated(true);
setBounds(-10,-100,getToolkit().getScreenSize().width+30,getToolkit()
.getScreenSize().height+110);
setVisible(true);
Am_I_In_FullScreen = true;
}
else{
setVisible(true);
setBounds(PrevX, PrevY, PrevWidth, PrevHeight);
dispose();
setUndecorated(false);
setVisible(true);
Am_I_In_FullScreen = false;
}
}
}
}
