Just as a preface, I am very new to programming in JavaFX. (We had an introduction to JavaFX in one of my classes last semester, and for the last month or so I've been working on making a simple game in JavaFX.)
An issue I've run into is trying to detect the collision of a Pane within one StackPane with the Pane inside another StackPane. Specifically, I have a "Player" node in the Game class ("Player" extends abstract "Sprite" which extends StackPane) along with some "Asset" nodes ("Asset" being an abstract parent class that like "Sprite" also extends StackPane). Both "Player" and every "Asset" node are comprised of an ImageView and Pane objects that are to be the "boundaries" of the node.
Here's how I'm attempting to track collisions in the Game class, but it's not working:
protected void update() {
// Call playerBoundsHandler in update cycle
for (Asset asset : this.gameArea.getAssets()) {
playerBoundsHandler(asset);
} // for
} // update
private void playerBoundsHandler(Asset asset) {
for (Pane boundary : asset.getAssetBoundaries()) {
if (player.getPlayerStandingAreaBox()
.getBoundsInParent()
.intersects(boundary.getBoundsInParent())) {
// do stuff here
} // if
} // for
} // playerBoundsHandler
I'm guessing there's something wrong with using getBoundsInParent() here since I'm trying to track the intersection of child nodes within two separate nodes, but I have no idea what the solution is. Is there something I need to do with getBoundsInLocal or some other method?
Here's the relevant part of the Player class for clarification's sake:
/**
* Player class constructor.
* Player class extends "Sprite" (abstract class)
* which extends StackPane.
*/
public Player(double xSpawn, double ySpawn) {
// Add Player Standing Box (a Pane situated at the feet of the Player sprite)
this.playerStandingAreaBox = new Pane();
// width, height, etc. set here
this.getChildren().add(playerStandingAreaBox);
this.setAlignment(playerStandingAreaBox, Pos.BOTTOM_CENTER);
} // Player constructor
public Pane getPlayerStandingAreaBox() {
return this.playerStandingAreaBox;
} // getPlayerStandingAreaBox
The Asset child classes follow a design almost identical to the Player class here. In case it's also needed for clarification, here's the "Highway" class:
public class Highway extends Asset {
public Highway(double translateX, double translateY) {
// call super here
setAssetBoundaries();
} // Highway constructor
@Override
setAssetBoundaries() {
Pane boundaryOne = new Pane();
// set boundaryOne settings
this.getChildren().add(boundaryOne);
this.assetBoundaries.add(boundaryOne);
Pane boundaryTwo = new Pane();
// set boundaryTwo settings
this.getChildren().add(boundaryTwo);
this.assetBoundaries.add(boundaryTwo);
} // setAssetBoundaries
/**
* assetBoundaries is an ArrayList<Asset> object also inherited.
* getAssetBoundaries() is inherited from the "Asset" class
* which returns assetBoundaries.
*/
The screenshot below shows my Player sprite (don't judge the awful pixel art! I already know the guy's right arm looks janky and the rifle looks ridiculous!) with his standing box highlighted in red, and the boundaries of a "Highway" Asset highlighted in yellow at both the very top and very bottom. I want to register when the Player's box intersects one of the boxes of the Highway.
