我一直在尝试使用 JavaScript 从网页向 Unity 函数发送消息，但在调用该函数时我仍然收到未找到的值。 关联的对象是 Canvas 的子对象，所以我不确定这是否是一个问题。我尝试了多种方法的组合来实现它
coilScore 是一个 float ，我只是传递数字。
我尝试到达子对象。
gameInstance.SendMessage('CoilValue', 'ReceiveCoilScore', coilScore);[![enter image description here][1]][1]
gameInstance.SendMessage('InGameCanvas/CoilValue', 'ReceiveCoilScore', coilScore);
gameInstance.SendMessage('InGameCanvas', 'ReceiveCoilScore', coilScore);
gameInstance.SendMessage('InGameCanvas.CoilValue', 'ReceiveCoilScore', coilScore);
Error:
SendMessage: object InGameCanvas/CoilValue not found! a4527c6b-a81a-4c23-8861-f3553ac675c8:8:48803
Type: number Total coilScore: 0.000001401 meta_monetization_handler.js:34:10
编辑
为了清楚起见，我在此行下方添加了其他信息。
index.html 正在调用 .js 文件。在该 .js 文件中，我正在解析多个参数，但我想做的一项是将消息从 .js 文件发送到 Unity。
index.html

console.log('document.monetization not found :(');
} else {

var latest_json_el = document.getElementById('latestJson');
document.monetization.addEventListener('monetizationstart', function(event) {
info_div.style.backgroundColor = "rgba(63, 65, 68, 0.4)";
ilp_element.innerHTML = "Interledger Enabled! (Meta-Tag)<br><br>:) Thank You!<br>";
ilp_raw_init_el.innerHTML = JSON.stringify(event.detail, null, 2).replace('{','').replace('}','');
});
document.monetization.addEventListener('monetizationprogress', function(event) {
if (typeof this.runningTotal == "undefined") {
this.runningTotal = 0;
}
var monetizationAmount = parseFloat(calcValue(event.detail));
this.runningTotal += monetizationAmount;
document.monetization.lastEventPayload = event.detail;
cur_pay_el.innerHTML = "Latest ILP Payment: $" + monetizationAmount;
total_estimate_el.innerHTML = "Estimated ILP Total: $" + this.runningTotal.toPrecision(4);
latest_json_el.innerHTML = "Latest ILP Payment Response: " + JSON.stringify(event.detail);
coilScore = this.runningTotal.toPrecision(4);
console.log("Type: " + typeof coilScore + " Total coilScore: " + coilScore );
gameInstance.SendMessage('CoilValueTextObject', 'ReceiveCoilScore', coilScore);
});
}
最佳答案
我更改了 Canvas 以匹配相机 View 。很久以后我还注意到 javascript 使用了 toPrecision(4) 并且我有一个接受 float 的函数。 toPrecision 正在将 float 转换为字符串，并使用字符串作为参数，因此它失败了。
解决方案:确保我发送的是一个字符串，并且接收端的函数接受一个字符串。
public void ReceiveCoilScore(float newValue)
{
//gameSession.coilScore = newValue;
//coilScoreText.text = string.Format("{0:N9}", gameSession.GetCoilScore());
coilScore = newValue;
coilScoreText.text = string.Format("{0:N9}", coilScore);
}
将 float 转换为字符串
coilScore = this.runningTotal.toPrecision(4);
console.log("Type: " + typeof coilScore + " Total coilScore: " + coilScore );
gameInstance.SendMessage('CoilValueTextObject', 'ReceiveCoilScore', coilScore);
