Getting an error when trying to use a string with meshes in unity:

Cannot implicitly convert type 'UnityEngine.Mesh' to 'UnityEngine.Mesh[]'

CodePudding user response：

I don't know which line is causing the exception, it's not clear how the modelYouWantToUse array is being populated, and I don't know Unity at all, but here's how I would do it:

public class HatSwitch : MonoBehaviour
{
    [SerializeField] private MeshFilter modelToChange;
    [SerializeField] private Mesh[] meshItems;

    private int currentMeshIndex = 0;

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space)) ChangeMesh();
    }

    public void ChangeMesh()
    {
        // Update the mesh
        modelToChange.mesh = meshItems[currentMeshIndex];

        // Increment our index
        currentMeshIndex  ;

        // Validate index is in range
        if (currentMeshIndex >= meshItems.Length) currentMeshIndex = 0;
    }

    public void ChangeMeshBack()
    {
        // Update the mesh
        modelToChange.mesh = meshItems[currentMeshIndex];

        // Decrement our index
        currentMeshIndex--;

        // Validate index is in range
        if (currentMeshIndex < 0) currentMeshIndex = meshItems.Length - 1;
    }
}
