我正在使用Phaser 3框架以JavaScript创建滑板游戏。我已经将渐变图像加载到屏幕上,并且当前正在文件中使用“ arcade”物理引擎。我知道我必须使用物质物理学引擎来创建非矩形的Hitbox。如何使用三角形的点击框实现它?
我有该坡道的.png图像文件,以及其命中框的.json文件。
我尝试按照网站上的教程进行操作,该教程介绍如何为物质物理引擎创建新的命中框。一切最终都从屏幕上消失了,我不知道如何使用.json文件进行爬坡。
//Configurations for the physics engine
var physicsConfig = {
default: 'arcade',
arcade : {
debug : true //CHANGE THIS TO TRUE TO SEE LINES
}
}
//Game configurations
var config = {
type: Phaser.AUTO,
width: 1200 ,
height: 600,
physics: physicsConfig,
scene: {
preload: preload,
create: create,
update: update
}
}
//Start the game
var game = new Phaser.Game(config);
function preload() {
//Images
this.load.image('sky', 'archery_assets/images/sky.png');
this.load.image('ground', 'skate_assets/images/ground.png');
this.load.image('up_ramp', 'skate_assets/images/up_ramp.png')
//Spritesheets
this.load.spritesheet('player', 'skate_assets/spritesheets/skater.png', {frameWidth: 160, frameHeight: 160});
}
function create() {
//Background
skyImg = this.add.image(600, 300, 'sky');
//Scale the images
skyImg.setDisplaySize(1200, 600);
groundImg = this.add.image(600, 600, 'ground');
groundImg.setDisplaySize(1200, 250);
//Create the player
this.player = this.physics.add.sprite(100, 410, 'player');
this.player.setCollideWorldBounds(true);
//Rolling animation
this.anims.create({
key: 'move',
frames: this.anims.generateFrameNumbers('player', {start: 0, end: 3}),
frameRate: 16,
repeat: -1 // <-- keeps the rolling animation going
});
//Pushing animation
this.anims.create({
key: 'push',
frames: this.anims.generateFrameNumbers('player', {start: 4, end: 8}),
frameRate: 16
});
//Start and keep the rolling animation going
this.player.anims.play('move', true);
//Up ramp (1st ramp)
this.upRamp = this.physics.add.sprite(700, 330, 'up_ramp');
this.upRamp.setSize(320, 150).setOffset(0, 175);
this.upRamp.enableBody = true;
this.upRamp.setImmovable();
this.upRamp.body.angle = 150;
//Input
this.cursors = this.input.keyboard.createCursorKeys();
//Spacebar
this.spacebar = this.input.keyboard.addKey(Phaser.Input.Keyboard.KeyCodes.SPACE);
this.physics.add.collider(this.player, this.upRamp);
}
function update() {
//Set variable for push speed
var playerPushSpeed = 0;
//If the spacebar is pressed
if (this.spacebar.isDown) {
//Play the push animation
this.player.anims.play('push', true);
//Push speed
playerPushSpeed += 175;
//Move player
this.player.setVelocityX(playerPushSpeed);
}
if (this.upRamp.body.touching.left) {
this.player.setVelocityY(-200);
}
}
我需要知道如何实现坡道的.png图像及其.json Hitbox文件,以便播放器可以正确地“骑乘”坡道。

您必须使用 physics: { default: 'matter' }
来更改 点击框的形状 。将此代码段用作参考:
var config = {
type: Phaser.AUTO,
width: 800,
height: 600,
backgroundColor: '#000000',
parent: 'phaser-example',
physics: {
default: 'matter',
matter: {
gravity: {
y: 0
},
debug: true
}
},
scene: {
create: create
}
};
var game = new Phaser.Game(config);
function create ()
{
this.matter.world.setBounds();
this.matter.add.rectangle(200, 200, 200, 200, {
chamfer: { radius: [230, 0, 200, 0 ] }
});
this.matter.add.mouseSpring();
}
您还可以使用PhysicsEditor,可以 check this tutorial 了解如何实现不同的形状。
编辑:
您可以使用 console.log(this.matter.bodies)
检查要实施的其他可用形状。
