How do I Instantiate a prefab in a list?
Hi, i'm a super newbie, I'm trying to piece together a loan amortization calculator, I got the calculator working but now I want to populate the amortization table. I've tried populating a List by instantiating a prefab in a horizontal layout group, but I'm failing to get it to work in the loop. Here is the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine.UI;
using UnityEngine;
using System;
public class CalculatorButtonScript : MonoBehaviour
{
[SerializeField]
private GameObject tableTemplate;
public Button theButton;
public InputField lnamt, intrate, _startDate, reperiod, mnthlypay, _rowNo, _date, _payment, _interest, _totalRepayment, _balancePrincipal, _balanceInterest, _total;
// public Text
private List<GameObject> buttons;
private void Thedate()
{
_startDate.text = DatePickerControl.dateStringFormato;
}
// Use this for initialization
void Start()
{
theButton = GetComponent<Button>();
theButton.onClick.AddListener(doTheMath);
}
void doTheMath()
{
Thedate();
DateTime payDate = DateTime.ParseExact(_startDate.text, "yyyyMMdd", null);
double interestRate = 0;
double monthlyInterest = 0;
double loanAmount;
double amortizationTerm = 0;
double currentBalance;
double cummulativeInterest = 0;
double monthlyPrincipal = 0;
double cummulativePrincipal = 0;
String imonthlyPayment, imonthlyInterest, icurrentBalance, icummulativeInterest;
loanAmount = double.Parse(lnamt.text);
currentBalance = loanAmount;
interestRate = double.Parse(intrate.text) * 0.01;
amortizationTerm = double.Parse(reperiod.text) * 12;
// Calculate the monthly payment and round it to 2 decimal places
var monthlyPayment = ((interestRate / 12) / (1 - (Math.Pow((1 + (interestRate / 12)), -(amortizationTerm))))) * loanAmount;
monthlyPayment = Math.Round(monthlyPayment, 2);
imonthlyPayment = Convert.ToString(monthlyPayment);
imonthlyPayment = String.Format("{0:C}", monthlyPayment);
mnthlypay.text = (imonthlyPayment);
// Storage List
amortPaymentList = new List<GameObject>();
// Loop for amortization term (number of monthly payments)
for (int j = 0; j < amortizationTerm; j++)
{
// Calculate monthly cycle
monthlyInterest = currentBalance * interestRate / 12;
monthlyPrincipal = monthlyPayment - monthlyInterest;
currentBalance = currentBalance - monthlyPrincipal;
if (j == amortizationTerm - 1 && currentBalance != monthlyPayment)
{
// Adjust the last payment to make sure the final balance is 0
monthlyPayment += currentBalance;
currentBalance = 0;
}
// Reset Date
payDate = payDate.AddMonths(1);
// Add to cummulative totals
cummulativeInterest += monthlyInterest;
cummulativePrincipal += monthlyPrincipal;
// This is the part where I'm totally lost
if (amortPaymentList.Count > 0)
{
foreach (GameObject tableTemplate in amortPaymentLists) //< ----- I have a prebab named 'Table' which I dropped in the 'tableTemplate' [SerialiseFiled]
{
amortPaymentList(tableTemplate.gameObject);
}
buttons.Clear();
}
foreach () // < ----- Not sure what to put here
{
GameObject button = Instantiate(tableTamplate) as GameObject;
button.SetActive(true);
button.transform.SetParent(tableTemplate.transform.parent, false);
}
// Add values to Amortization Table
imonthlyInterest = Convert.ToString(monthlyInterest);
imonthlyInterest = String.Format("{0:C}", monthlyInterest);
icurrentBalance = Convert.ToString(currentBalance);
icurrentBalance = String.Format("{0:C}", currentBalance);
icummulativeInterest = Convert.ToString(cummulativeInterest);
icummulativeInterest = String.Format("{0:C}", cummulativeInterest);
_rowNo.text = (j + 1).ToString();
_date.text = payDate.ToString("yyyyMMdd");
_payment.text = (imonthlyPayment);
_interest.text = (imonthlyInterest);
_totalRepayment.text = (imonthlyPayment) + (imonthlyInterest);
_balancePrincipal.text = (icurrentBalance);
_balanceInterest.text = (icummulativeInterest);
_total.text = (icurrentBalance) + (icummulativeInterest);
}
}
}
