Problems with Trigonometry and LERPing
Hello everyone!
I have recently gotten back to Unity after a long hiatus of sorts. To try some stuff out, I made a simple test program.
The program was supposed to move a box through the trajectory of a cosine function, going down and then going up in the same position 5 units later. The code works, and the function is fine. However, the LERP function I used to modify the x value of the function, for some reason, accelerated on the start and slowed down by the end. While it did look nice, I wanted a simple, linear movement with no variation to speed.
I tried a lot of different solutions online, but none of them worked!
Here is the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TestTrig : MonoBehaviour {
public float multiplier;
float TrigFunc(float axisX)
{
float axisY = Mathf.Cos(2f * Mathf.PI * axisX);
return axisY;
}
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
float x = Mathf.Lerp(transform.position.x, 5f, Time.deltaTime * 2f);
float y = TrigFunc(x);
transform.position = new Vector3(x, y, 0);
}
}
