Phaser timer activated events. How?
问题
我正在尝试制作一个游戏，其中某些事情是基于不断增加的计时器而发生的。例如，在特定屏幕上经过一定时间后，某些文本、图像或可点击按钮才会出现。或者当计时器等于某些数字时，可能会在屏幕上短暂地闪现一张图片。
不幸的是，我不知道如何实现这个功能。有人可以给我展示一个解决方案吗？最好有示例。
如果有帮助的话，我正在使用VSCode中的Phaser 3。
英文:
I'm trying to make a game where certain things happen based on a timer that keeps going up. For example, certain text, images, or clickable buttons only appear after a certain amount of time has passed on a specific screen. Or maybe an image briefly flashes onto the screen when the timer equals certain numbers.
Unfortunately, I have got no clue how to make this happen. Can anyone show me a solution? Examples are perfered.
If it helps, I'm using Phaser 3 in VSCode.

我建议查看时间文档或官方主页上的时间示例。
基本上，你只需要使用this.time.addEvent( ... );。
更新：这里是一个简短的演示：
document.body.style = 'margin:0;';
var config = {
type: Phaser.AUTO,
width: 536,
height: 183,
scene: {
create,
update
}
};
function create() {
this.label1 = this.add.text(50, 50, '计时器: 0')
.setScale(2.5)
.setOrigin(0)
.setStyle({ fontStyle: 'bold', fontFamily: 'Arial' });
this.label2 = this.add.text(50, 100, '更新计时器: 0')
.setScale(2.5)
.setOrigin(0)
.setStyle({ fontStyle: 'bold', fontFamily: 'Arial' });
this.currentAppTime = 0;
let counter = 1;
this.time.addEvent({
delay: 1500,
callback: () => this.label1.setText(`计时器: ${counter++}`),
callbackScope: this,
loop: true
});
}
function update(time, delta) {
let helperTime = Math.floor(time / 1000);
if (helperTime > this.currentAppTime) {
this.currentAppTime = helperTime;
this.label2.setText(`更新计时器: ${this.currentAppTime}`)
}
}
new Phaser.Game(config);
英文:
I sugest checking out the time documentation, or the time examples on the official homepage.
Basically you just need to use this.time.addEvent( ... );
UPDATED Herer a short demo:
<!-- begin snippet: js hide: false console: false babel: false -->
<!-- language: lang-js -->
document.body.style = 'margin:0;';
var config = {
type: Phaser.AUTO,
width: 536,
height: 183,
scene: {
create,
update
}
};
function create () {
this.label1 = this.add.text(50, 50, 'Timer: 0')
.setScale(2.5)
.setOrigin(0)
.setStyle({fontStyle: 'bold', fontFamily: 'Arial'});
this.label2 = this.add.text(50, 100, 'Update Timer: 0')
.setScale(2.5)
.setOrigin(0)
.setStyle({fontStyle: 'bold', fontFamily: 'Arial'});
this.currentAppTime = 0;
let counter = 1;
this.time.addEvent({
delay: 1500,
callback: () => this.label1.setText(`Timer: ${counter++}` ),
callbackScope: this,
loop: true
});
}
function update(time, delta){
let helperTime = Math.floor(time / 1000);
if(helperTime > this.currentAppTime){
this.currentAppTime = helperTime;
this.label2.setText(`Update Timer: ${this.currentAppTime}` )
}
}
new Phaser.Game(config);
