Real-Time Mesh Deforming problem

[system]

Hey everyone. I want to know if it’s possible to make such a Real-time mesh Deformation System like I am thinking to do. My way to do this would be a OnCollisionEnter in the Mesh to get the Contact Point with the collisor and pass this Vector3 to a function wich is a for loop that check de Distance of each vertice to the contact Point and if it’s less than like 20.0F the vertice go down in the y axis with the strength of CollisorMass/DistanceToContactPoint.
I apply this way of think in a script but the deformation is not occurring in the Contact Point and sometimes the mesh not even deform. Here are the two necessary voids:

void Deform(Vector3 colPos, float colMass) {
	
	Vector3 newColPos = new Vector3(colPos.x, 0, colPos.z);
	 Mesh mesh = GetComponent<MeshFilter>().sharedMesh;
		Vector3[] vertices = mesh.vertices;
	for(int i = 0; i < mesh.vertexCount; i++) {
		float distance = Vector3.Distance(vertices*, newColPos);*

•   if(distance < 20.0F) {*
  

vertices = new Vector3(vertices.x, vertices_.y, vertices*.z - (colMass/distance));*_

* }*
* }*
mesh.vertices = vertices;
* mesh.RecalculateBounds();*

* }*

* void OnCollisionEnter(Collision collider) {*

* Vector3 colPosition = collider.contacts[0].point;*
* Deform(colPosition, collider.gameObject.GetComponent().mass);*
* }*
Hope you guys can help me with this!

You must convert the contact point to object space, since the mesh.vertices is in object space.

Just substitute the following line in OnCollisionEnter:
Vector3 colPosition = renderer.worldToLocalMatrix * collider.contacts[0].point;

Now, for this to work as intended, avoid changing the gameObject’s scale. Otherwise you’ll have to change how you measure distance in object space.
