I am new to JavaFx and i am making a simple drawing program where i draw shapes. The problem i am having now is that i dont know how to make the circle appear on the screen when i click on the screen. So first I want to press a button that says "Circle" and then when i click on the canvas i want it to spawn. (I am switching between scenebuilder and intellij btw).
This is some of my program:
Classes:
public abstract class Shape {
double x;
double y;
double width;
double height;
public Color color = Color.WHITE;
public void creatingShapes(double x, double y, int width, int height) {
this.x = x;
this.y = y;
this.width = width;
this.height = height;
}
public void setColor(Color color) {
this.color = color;
}
public double getX() {
return x;
}
public void setX(double x) {
this.x = x;
}
public double getY() {
return y;
}
public void setY(double y) {
this.y = y;
}
public double getWidth() {
return width;
}
public void setWidth(double width) {
this.width = width;
}
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
public Color getColor() {
return color;
}
public abstract void draw(GraphicsContext g);
}
public class Circle extends Shape {
#Override
public void draw(GraphicsContext g) {
g.setFill(color);
g.fillOval(200,200,200,200);
g.fillRect(getX(),getY(),getWidth(),getHeight());
g.setStroke(Color.BLACK);
g.strokeOval(getX(),getY(),getWidth(),getHeight());
====================================================
Controller class:
public class HelloController {
#FXML
private Button logoutButton;
#FXML
private BorderPane scenePane;
Stage stage;
#FXML
private ColorPicker myColorPicker;
#FXML
private ChoiceBox<String> myChoiceBox;
#FXML
private Button circle;
#FXML
private GraphicsContext g;
private final Shape[] shapes = new Shape[500];
Canvas canvas = new Canvas(310,333);
boolean drawShape = true;
int count = 0;
private final Color currentColor = Color.BLUE;
private final String[] menuAlternatives = {"Sparning", "Testing?", "Exit?"};
public void onCircleClicked() {
circle.setOnAction((event) -> addShape(new Circle()));
}
//skapa shapes
public void addShape(Shape shape) {
shape.setColor(currentColor);
shape.creatingShapes(10,10,150,100);
shapes[count] = shape;
count++;
paintCanvas();
}
public void changeColor(ActionEvent event) {
Color myColor = myColorPicker.getValue();
scenePane.setBackground(new Background(new BackgroundFill(myColor, null, null)));
}
public void initialize() {
g = canvas.getGraphicsContext2D();
}
public void paintCanvas() {
g.setFill(Color.WHITE);
g.fillRect(0,0,400,400);
Arrays.stream(shapes, 0, count).forEach(s -> s.draw(g));
}
Placing a circle on canvas with mouse event
From Doc
public void fillOval(double x,
double y,
double w,
double h)
Fills an oval using the current fill paint.
This method will be affected by any of the global common or fill attributes
as specified in the Rendering Attributes Table.
Parameters:
x - the X coordinate of the upper left bound of the oval.
y - the Y coordinate of the upper left bound of the oval.
w - the width at the center of the oval.
h - the height at the center of the oval.
As we can see x and y params from fillOval() will put the circle at the left upper corner of its bound . to spawn at its very center , we need to subtract half widht and half height to x and y coordinates given by mouseclick event.
this is a single class javafx app you can try
App.java
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.canvas.Canvas;
import javafx.scene.canvas.GraphicsContext;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class App extends Application {
#Override
public void start(Stage stage) {
Canvas canvas = new Canvas(640, 480);
GraphicsContext context = canvas.getGraphicsContext2D();
canvas.setOnMouseClicked(e -> {
double x = e.getX();
double y = e.getY();
context.setFill(Color.AQUAMARINE);
context.setStroke(Color.BLACK);
context.fillOval(x - 20, y - 20, 40, 40);
context.strokeOval(x - 20, y - 20, 40, 40);
});
var scene = new Scene(new Group(canvas), 640, 480);
stage.setScene(scene);
stage.setTitle("spawn with mouse click");
stage.show();
}
public static void main(String[] args) {
launch();
}
}
I am new to Unity, but not to C#, so I would love to avoid using Bolt. I don't mind spending the extra time making sure that my animations are correct.
I am trying to get a gun to shoot (the animation part [aka recoil])
As you probably can see that there are no parameters (in the first image). In the parameter box (where it says list is empty in the animator window), I clicked on the '+' to create a new parameter trigger (called it "M1911SHOOT")
However it does resolve the Parameter does not exist error message but nothing happens afterwards
Here is my code
M1911.cs
public class M1911 : Weapons
{
private const string IDLE = "M1911IDLE";
private const string BASIC = "M1911SHOOT";
// Start is called before the first frame update
void Start()
{
IDLEANIM = IDLE;
BASICATKANIM = BASIC;
weaponName = "Weapon";
damage = 15;
heavyDamage = 35;
weight = 5;
staminaCost = 5;
range = 3.5f;
atkDelay = .7f;
type = WEAPONTYPE.MELEE;
Init();
}
}
Weapons.cs
public class Weapons : MonoBehaviour
{
protected enum WEAPONTYPE
{
NONE,
RANGED,
MELEE
}
protected string weaponName;
protected int damage;
protected int heavyDamage;
protected int weight;
protected int staminaCost;
protected float range;
protected WEAPONTYPE type;
protected bool isAtking;
protected float atkDelay;
protected string BASICATKANIM;
protected string HEAVYATKANIM;
protected string IDLEANIM;
protected string CURRENTANIMATION;
private Animator _animator;
protected void Init()
{
CURRENTANIMATION = IDLEANIM;
_animator = GetComponent<Animator>();
isAtking = false;
}
public int Attack()
{
if (!isAtking)
{
isAtking = true;
ChangeAnimation(BASICATKANIM);
return damage;
}
return 0;
}
void AttackComplete()
{
isAtking = false;
}
public void ChangeAnimation(string newAnimationState)
{
if(newAnimationState == CURRENTANIMATION)
return;
if (isAtking)
{
CURRENTANIMATION = newAnimationState;
Invoke("AttackComplete", atkDelay);
}
_animator.SetBool(BASICATKANIM, true);
_animator.SetBool(IDLEANIM, false);
CURRENTANIMATION = newAnimationState;
}
}
Player.cs
public class Player : CharacterAttributes
{
public Weapons weapon;
// Start is called before the first frame update
void Start()
{
Init();
}
// Update is called once per frame
void Update()
{
Move();
if (Input.GetMouseButtonDown(0))
Attack();
}
void Move()
{
//Movement stuff
}
void Attack()
{
weapon.Attack();
}
}
Wrong method in Weapon.cs
Needed
_animator.Play(BASICATKANIM);
instead of
_animator.SetBool(IDLEANIM, false);
I wanted to play an animation, not play around with the parameters for the animator
I have a problem again with the JavaFX Chart : D
Context :
I had Popup/Label on my chart to display the value on hover : JavaFX LineChart Hover Values (Jewelsea answer)
Problem :
But when the point are near the edges of chart, the popup is hidden by them.
The chart with problem, I highlighted the edges of chart.
This is a problem, because my popup is bigger and display more informations (x value, y value and the data serie)
Possible solutions :
May I can check where the edges are, and if the popup is hide. In this case, I should shift the popup. But when I look doc, I didn't found the right method :
XYChart
XYChart.Data#nodeProperty
May I can put the popup above the chart. Like z-index in CSS.

Thank you in advance ! And my apologies about my english, still learning !
I have been looking on the JavaFX CSS reference guide and I could'nt find anything to simply solve your problem.
A possible solution is to translate your symbol depending on how near it is to the max or min value.
I wrote something like this, based on your code :

Basically, I am just saying that all values <= min+5 and >= max-5 must be translated.
The +/- 5 is arbitrary and should be calculated from the ticks gap and plot scale to have a perfect repositioning. Anyway, without performing any maths, it is still quite satisfying.
Based on Mr Kwoinkwoin solution, I wrote my own.
Im not sure if its possible to optimize it or improve it. But seems to be working for me so far.
