Assigning a Sprite to a Script and creating a Gameobject out of that sprite

Questions & Answers
1

Hey,
I am creating some Scripts to improve the work with unity’s 2D-Tools.
So I created a Script that changes the Scene-view to a tile-Based editor with snap-grid.
And now i have a little thing I want to improve.
Right now I create a Game-Object when leftclicking but in the inspector I have to assign a prefab of a gameobject with a sprite renderer on it to tell the editor what object should be created. And I dont want to create a prefab for every Sprite that is in the game.
And now i would like to know if there is a way to convert a sprite into an gameobject, because i just want to be able to assign a Sprite in the inspector and afterwards when i left click its creates the gameobject out of this sprite.

Maybe someone knows if this works and can tell me how.
If it isnt working that way I am happy if you maybe tell me some other ways to do this. Even if you have a completley different attempt that would work I want to know.

Here my scripts(If you don’t know what a special line of the code does just ask):

using UnityEngine;
using System.Collections;

public class LevelDesigner : MonoBehaviour {
	public GameObject prefab; // I want this to be a Sprite and not a gameobject
	public Vector2 gizmoPosition;

	public float depth =0;

	void OnDrawGizmos(){
		Gizmos.DrawWireCube(new Vector3(gizmoPosition.x,gizmoPosition.y,depth), new Vector3(1,1,1));
	}
}

And the 2nd scripr:

using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomEditor(typeof(LevelDesigner))]
public class LevelDesignerEditor : Editor
{

		LevelDesigner script;
		Vector2 oldTilePos = new Vector2 (); 
		void OnEnable ()
		{
				script = (LevelDesigner)target; 
				if(!Application.isPlaying){
			if(SceneView.lastActiveSceneView != null){

			SceneView.lastActiveSceneView.orthographic = true;
			SceneView.lastActiveSceneView.LookAtDirect(SceneView.lastActiveSceneView.pivot,Quaternion.identity);
			
			}
			}
		}

		public override void OnInspectorGUI ()
		{
				
				script.depth = EditorGUILayout.Slider (script.depth, -5, 5);
			
				EditorGUILayout.BeginHorizontal ();
				EditorGUILayout.PrefixLabel ("Tile(prefab)");
				script.prefab = (GameObject)EditorGUILayout.ObjectField (script.prefab, typeof(GameObject), false);
				EditorGUILayout.EndHorizontal();

		if (GUI.changed)
						EditorUtility.SetDirty (target);
		}

		void OnSceneGUI ()
		{

				
				Ray ray = HandleUtility.GUIPointToWorldRay (Event.current.mousePosition);
				Vector2 tilePos = new Vector2 (); 
				tilePos.x = Mathf.RoundToInt (ray.origin.x); 
				tilePos.y = Mathf.RoundToInt (ray.origin.y); 

				if (tilePos != oldTilePos) { 
						script.gizmoPosition = tilePos;
						SceneView.RepaintAll ();
						oldTilePos = tilePos;
				}
	

		Event current = Event.current;
		if(current.type == EventType.mouseDown)
		{
			string name = string.Format("Tile{0}_{1}_{2}",script.depth,tilePos.y,tilePos.x);
			if(current.button ==0)
			{
				CreateTile(tilePos,name);
			}
			if(current.button ==1) 
			{
				DeleteTile(name);
            }
		}
				if (GUI.changed)
						EditorUtility.SetDirty (target); 
		}

	void CreateTile(Vector2 tilePos, string name)
	{
		 if(!GameObject.Find(name))
		{
			Vector3 pos = new Vector3(tilePos.x, tilePos.y,script.depth);
			GameObject go = (GameObject)Instantiate (script.prefab,pos,Quaternion.identity);
			go.name = name;
		}
	}

	void DeleteTile(string name)
	{
		GameObject go = GameObject.Find(name);

		if(go!=null)
		{
			DestroyImmediate(go);
		}
	}
}

I didn’t read everything, but this is how I would instantiate a GameObject sprite.

public class Test : MonoBehaviour
{
	public Sprite sprite;

	void Start()
	{
		GameObject go = new GameObject("Test");
		SpriteRenderer renderer = go.AddComponent<SpriteRenderer>();
		renderer.sprite = sprite;
	}
}
