てきとう。エラー出るはず！

suikomi.cs

Mesh mesh = GetComponent<MeshFilter>().mesh;
Vector3 targetPoint;
Vector3[] vertices = mesh.vertices;
float power; //吸い込まれ力

for(int i = 0; i < vertices.Length; i++){
	//ここら変の計算を変えて、吸い込まれ方を調整
	float d = (vertices[i] - targetPoint).sqrMagnitude;
	vertices[i] += (vertices[i] - targetPoint)*Time.deltaTime*d*power;
}

mesh.vertices = vertices;
mesh.RecalculateNormals();
