Я нашел решение, хотя я не знаю, хотите ли вы его использовать. Я обнаружил этот плагин , который облегчает управление коллизиями с Phaser .
Выполните следующие действия:
- Сначала , добавьте эту строку
<script src="//cdn.jsdelivr.net/npm/phaser-matter-collision-plugin"></script>
в свой файл game_index.html
, например:
<script src="//cdn.jsdelivr.net/npm/phaser-matter-collision-plugin"></script>
<script src= "skateboarding.js" ></script>
<script src = "archery.js"></script>
<script src = "soccer.js"></script>
Если вы хотите установить его по-другому, прочитайте полное руководство по установке .
- Второе ,в объекте
config
добавьте этот фрагмент кода:
plugins: {
scene: [
{
plugin: PhaserMatterCollisionPlugin, // The plugin class
key: "matterCollision", // Where to store in Scene.Systems, e.g. scene.sys.matterCollision
mapping: "matterCollision" // Where to store in the Scene, e.g. scene.matterCollision
}
]
},
Теперь ваш объект config
должен выглядеть следующим образом:
//Game configurations
var config = {
type: Phaser.AUTO,
width: 1500, //<-- this is the width of what we will see at one time
height: gameHeight,
physics: physicsConfig,
plugins: {
scene: [
{
plugin: PhaserMatterCollisionPlugin, // The plugin class
key: "matterCollision", // Where to store in Scene.Systems, e.g. scene.sys.matterCollision
mapping: "matterCollision" // Where to store in the Scene, e.g. scene.matterCollision
}
]
},
scene: {
preload: preload,
create: create,
update: update
}
}
Третий , удалите этот фрагмент кода:
//Detect the player's collision with the ground
this.matter.world.on('collisionstart', function (onGround, skater, ground) {
//If the player is touching the ground, set this value to true
skaterTouchingGround = true;
});
//Detect collision when we are on the bench, so we can play the grind animation
this.matter.world.on('collisionstart', function (grindNow, skater, bench) {
grind = true;
});
Четвертый , там же, где вы удалили предыдущие фрагменты кода, добавьте этот кодблоки:
//Detect the player's collision with the ground
this.matterCollision.addOnCollideStart({
objectA: skater,
objectB: ground,
callback: () => skaterTouchingGround = true
});
//Detect collision when we are on the bench, so we can play the grind animation
this.matterCollision.addOnCollideStart({
objectA: skater,
objectB: bench,
callback: () => grind = true
});
Теперь вы можете получить значение grind
, напечатанное в console
при касании player
касается bench
.
Для справки здесьэто весь код:
//Define our start button for out index page
var startButton = document.querySelector("#startSkate").addEventListener("click", () => {
//Delay in ms to remove our button
let removeDelay = 1;
//Call function to start the game
this.startSkateGame();
//Call the setTimeout method and define a function
setTimeout(function () {
//Get elements and remove them to clear the page
document.getElementById('startArch').remove();
document.getElementById('startSkate').remove();
document.getElementById('startSoccer').remove();
document.getElementById('logo').remove();
//Pass the delay
}, removeDelay);
});
//Define the function that we call when our start button is clicked
startSkateGame = () => {
//Configurations for the physics engine
var physicsConfig = {
default: 'matter',
matter : {
gravity: {
x: 0,
y: 2.5, // <--This is the only way I could get the skater to roll up the ramp.s
},
debug: true //CHANGE THIS TO TRUE TO SEE LINES
}
}
//Variables for height and width
var gameHeight = 750;
var gameWidth = 5000;
//Game configurations
var config = {
type: Phaser.AUTO,
width: 1500, //<-- this is the width of what we will see at one time
height: gameHeight,
physics: physicsConfig,
plugins: {
scene: [
{
plugin: PhaserMatterCollisionPlugin, // The plugin class
key: "matterCollision", // Where to store in Scene.Systems, e.g. scene.sys.matterCollision
mapping: "matterCollision" // Where to store in the Scene, e.g. scene.matterCollision
}
]
},
scene: {
preload: preload,
create: create,
update: update
}
}
