Spawn meshes to scene via dropdown UI button
Hello. I am a new programmer and i want your help. I am working a project where i try to select and spawn a primitive mesh in scene via a dropdown button. I never use something like that so if anyone can help me. I have made an array wich i include my primitives meshes and i want to select them when i select the dropdown options. Here is my code:
using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;
public class ChangeMeshFilter : MonoBehaviour { public Mesh[] myMesh= new Mesh[5]; private int a = 0; private GameObject gObject; public Dropdown MeshSelector;
void Start ()
{
CreateObject();
}
void CreateObject() {
gObject = new GameObject();
gObject.AddComponent<MeshFilter>().mesh = myMesh[0] ;
gObject.AddComponent<MeshRenderer>();
gObject.GetComponent<MeshRenderer>().material.color = Color.green;
}
public void Changer()
{
if (a < 4)
{
a = a + 1;
}
else
{
a = 0;
}
gObject.GetComponent<MeshFilter>().mesh = myMesh[a];
}
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class ChangeMeshFilter : MonoBehaviour
{
public Mesh[] myMesh= new Mesh[5];
private GameObject gObject;
public Dropdown MeshSelector;
void Start ()
{
CreateObject();
MeshSelector.onValueChanged.AddListener(SelectMesh);
}
void CreateObject() {
gObject = new GameObject();
gObject.AddComponent<MeshFilter>().mesh = myMesh[0] ;
gObject.AddComponent<MeshRenderer>();
gObject.GetComponent<MeshRenderer>().material.color = Color.green;
}
private void SelectMesh(int index)
{
gObject.GetComponent<MeshFilter>().mesh = myMesh[index];
}
Hi and thanks for you time. So if i understand right i must use this script to my script? Or i must you 2 different scripts
The script I've provided is meant to replace yours.
You are the best my friend. Really thanks you. A last question. If i want to select the type of the mesh with the dropdown button, but i want to span this mesh on screen with an other one? is it possible?
Thanks for your time again
Hi,
Could you please clarify if you want to have an inspector attribute with a dropdown via which you select the type of mesh you want to spawn in your scene or you wan this function to be during run-time in UI?
if you want to make this in the inspector then do this
enum DDLEnum
{
Item1,
Item2,
Item3
};
var dropDown = DDLEnum.Item1;
Hello and thanks for your time. I would like to make it work in runtime
