我正在尝试为我正在开发的平台游戏中的角色制作文本。下面是我的代码:
create方法中的代码:

this.dialog = this.add.text(880, 810, ' ', { font: '30px Futura', fill: '#FFFFFF' }).setOrigin(0.5);

update方法中的代码:

if ((this.checkCollision(this.p1, this.goodLamb) || this.checkCollision(this.p1, this.stiches)) && (this.has("spool") && this.has("needleOne") && this.has("needleTwo")) && this.keyT.isDown) {
        console.log("spool: " + this.has("spool") + " needleOne: " + this.has("needleOne") + " needleTwo: " + this.has("needleTwo"));
        this.dialog.setText('Oh, thanks Peef! Now we can fix Stiches!');
    }
    else if ((this.checkCollision(this.p1, this.goodLamb) || this.checkCollision(this.p1, this.stiches)) && (!(this.has("spool")) || !(this.has("needleOne")) || !(this.has("needleTwo"))) && this.keyT.isDown){
        console.log("spool: " + this.has("spool") + " needleOne: " + this.has("needleOne") + " needleTwo: " + this.has("needleTwo"));
        this.dialog.setText('Peef! Stiches ripped herself again! Can you get the sewing supplies?');
    }
    else{
        this.dialog.setText('');
    }

请注意,this.p1是播放器,this.goodlamb和this.stiches是字符,字符串spool、needleOne和needleTwo表示投资库中的项目。
目前的代码只在玩家与npc发生冲突并按住T按钮时显示文本,我通常使用T按钮进行交互,但按住T按钮查看文本并不是我想要的。
我的目标是这样的:玩家与npc发生碰撞,按一下按钮,显示一行文字,阅读完后再按一次按钮,当前行消失,出现另一行文字,如此反复,直到没有行文字。
我不知道该怎么做。有什么建议吗?
如果有帮助的话,我在VSCode中使用Phaser 3,使用街机物理。

简单的解决方案是创建为Text - GameObject并在两者之间交替。
只需要一个简单的模运算,就像currentLine % 2 == 0,然后根据结果切换Text - GameObject

    • 下面是一个简短的工作演示,展示了主要思想:**
  • (我在显示文本时添加了一个补间,只是为了一些天赋。也可以添加一个来隐藏文本)*

文字的颜色只是,以显示有2个不同的Text-GameObjects

document.body.style = 'margin:0;';

var config = {

let line0;
let line1;
let tween;
let currentLine = -1;

let messages = [ 
  "this is the first line", 
  "this is the second line", 
  "this is the third line",
  "DONE! Next Click restart"
];

function create () {
    this.add.text(10, 10, 'Click for next message')
        .setScale(1.5)
        .setOrigin(0)
        .setStyle({fontStyle: 'bold', fontFamily: 'Arial'});

    line0 = this.add.text(10, 40)
        .setScale(1.5)
        .setColor('#ff0000')
        .setOrigin(0)

    this.input.on('pointerdown',  _ => {

        if(currentLine >= messages.length-1){
          currentLine = -1;
        }
        
        currentLine++;
        let nextLine = messages[currentLine];

        // stop running tween, just to be on the safe side
        if(tween){
           tween.stop();
        }

        // Hide both
        line0.setAlpha(0);
        line1.setAlpha(0);

        //switch between two text gameobjects
        if( currentLine % 2 == 0){
            line0.setText(nextLine);

            // Just to make the fade-in animation
            tween = this.tweens.add({
                targets: [ line0 ],
                alpha: 1,
                duration: 500

                duration: 500
            });
        }
    });
}
