Terrain edit problem

so i have a terrain editing script, with the intention to target part of the ground near the player, raise it and if it's close enough to the player, lift him with it aswell i also have a script that spawns rock onto the edited terrain, for a better effect my only problem is that rather than lifting the player, he falls through the terrain when he collides with nearby edited terrain any idea how i can fix this? i was thinking of giving the rocks some script to teleport the player up when he collides, but when i tried it didn't work here's the main terrain editing script im using

using UnityEngine; using System.Collections;

public class TerrainEdit : MonoBehaviour { public Terrain myTerrain; int xResolution; int zResolution; float[,] heights;

 void Start()
 {
     xResolution = myTerrain.terrainData.heightmapWidth;
     zResolution = myTerrain.terrainData.heightmapHeight;
     heights = myTerrain.terrainData.GetHeights(0,0,xResolution,zResolution);
 }
 
 void Update()
 {

     if(Input.GetMouseButton(1))
     {
         RaycastHit hit;
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         if(Physics.Raycast(ray, out hit))
         {
             raiseTerrain(hit.point);
         }
     }
 }

 private void raiseTerrain(Vector3 point)
 {
     int terX =(int)((point.x / myTerrain.terrainData.size.x) * xResolution);
     int terZ =(int)((point.z / myTerrain.terrainData.size.z) * zResolution);
     float y = heights[terX,terZ];
     y += 0.001f;
     float[,] height = new float[1,1];
     height[0,0] = y;
     heights[terX,terZ] = y;
     myTerrain.terrainData.SetHeights(terX, terZ, height);
 }

}

note: i lowered the ammount of terrain that gets lifted up, and my original idea to lift the player works as long as he's moving backwards
