Unable to set localPosition coins on top of Superspline

Questions & Answers

Hello,

I am unable to set the localPosition of coins Instantiated on of a Supersline.

On Y-Axis View

=================

0 0 0 0 0 0 ---X-AXIS-->

=================

When I set the position of each coin to (1f, 0f, 0f), I get:

=================

  0 0 0 0 0 0 ---X-AXIS-->

=================

Notice the all coins are shifted to the left. (Shifted using the World positioning)
The desired result would be something like:

=================

              ---X-AXIS-->
0 0 0 0 0 0 
=================

Where the coins are shifted to their Left/Right.
The script below, I attach it to my “Superspline”.

using UnityEngine;
using System;
using System.Collections;
using System.Collections.Generic;

//This class computes a point on a spline that is as close as possible to a given gameobject
public class CoinPlacement : MonoBehaviour
{
    public Spline spline;
    
    public GameObject prefabCoin;
    public GameObject prefabCoinBig;
    
    public int coinCount = 100;
    public int coinsInEachGroup = 5;        
    
    void Start( )
    {
        int coinGroupCount = (coinCount / coinsInEachGroup)+coinsInEachGroup;
            
        GameObject[] prefabs = new GameObject[2] {prefabCoin, prefabCoinBig};
        
        System.Random rnd = new System.Random();
        
        //Create an array with intervals we wan.
        //EG: starting points every 5 "steps"
        int[] coinStartPoints = new int[coinGroupCount];
        for (int i = 0; i < coinGroupCount; i++) {
            coinStartPoints _= (i+(i+coinsInEachGroup))*coinsInEachGroup;_

}

for (int i = 0; i < coinCount; i++) {
//put coins in succession. EG in 12345 in a straight line
for(int x=0; x<coinStartPoints.Length; x++) {
if(i == coinStartPoints[x]) {
for(int k=0; k<coinsInEachGroup; k++) {
cloneCoin(i+k, prefabs);
}
i = i + coinsInEachGroup;
}
}
}
}

private void cloneCoin(int i, GameObject[] prefabs) {
GameObject clone;

clone = Instantiate(
prefabs[0],
Vector3.Lerp (
spline.GetPositionOnSpline(0),
spline.GetPositionOnSpline(i / (float)coinCount),
1
) + new Vector3(0f,coinYOffset,0f),
spline.GetOrientationOnSpline(i)
) as GameObject;

Debug.Log(clone.transform.position);

clone.transform.parent = transform;
clone.transform.localPosition = new Vector3(1f, 0f, 0f);

Debug.Log("after: "+clone.transform.position);

}

void Update() {

}

}
Thanks!

Got it working!

	private void cloneCoin(int i, GameObject[] prefabs) {
		GameObject clone;
		GameObject clone1;
		
		Debug.Log(spline.GetClosestPoint(spline.GetPositionOnSpline(i / (float)coinCount), i ));
		
		var lerpTo = i / (float)coinCount;
		clone = Instantiate(
			prefabs[0], 
			Vector3.Lerp (
				spline.GetPositionOnSpline(0), 
			 	spline.GetPositionOnSpline(lerpTo),
				1
			) + new Vector3(0f,coinYOffset,0f), 
			spline.GetOrientationOnSpline(i)
		) as GameObject;
		
		clone.transform.rotation = spline.GetOrientationOnSpline(lerpTo);
		clone.transform.Translate(new Vector3(-1f, 0f, 0f), Space.Self);
	}
