OnMouseEnter and OnMouseExit for multiple materials
Hey guys! I am writing a script to highlight the object in the scene. The object has 3 materials. So, using the example from the documentation for OnMouseOver ( https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnMouseOver.html ) I wrote the script, which has the following idea:
MeshRenderer gets all materials from the object and puts in a list. Then in the for-loop the color of each material is added to the list of the initial materials' colors. In OnMouseEnter method each initial material is assigned a new color. And in the OnMouseExit (i haven't completed it yet) the initial materials are to be assigned to the object. Here is the script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Linq;
public class Selection : MonoBehaviour
{
public List<Material> bldg_mats_init;
public List<Color> mat_color_init;
private Material mat;
Color colorSelection = Color.red;
MeshRenderer m_Renderer;
void Start()
{
m_Renderer = GetComponent<MeshRenderer>();
List<Material> bldg_mats_init = m_Renderer.materials.ToList();
Debug.Log("Numer of bldg_mats_init:" + bldg_mats_init.Count);
for (int i = 0; i < bldg_mats_init.Count; i++)
{
mat = bldg_mats_init[i];
mat_color_init.Add(mat.color);
Debug.Log("Stored colors:" + mat_color_init.Count);
}
Debug.Log("Number of init mat colors:" + mat_color_init.Count);
}
private void OnMouseEnter()
{
Debug.Log("Number of init materials (OME):" + bldg_mats_init.Count);
Debug.Log("Number of init colors (OME):" + mat_color_init);
for (int i=0; i < bldg_mats_init.Count; i++)
{
material_bldg = bldg_mats_init[i];
m_Renderer.material.color = colorSelection;
}
}
private void OnMouseExit()
{
for (int i = 0; i < bldg_mats_init.Count; i++)
{
}
}
}
And it doesn't work. So the Debug.Log in the OnMouseOver method doesn't return the right number of materials obtained in Start. What could be the problem?
Thank you in advance!
