Create Unity UI Panel via Script
I want to create a relatively simple UI via C# script only and it should have a simple background rectangle.
For that I created a canvas via C# and want to place some other elements in it.
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class Test : MonoBehaviour
{
private void Awake()
{
GameObject obj = new GameObject();
Canvas canvas = obj.AddComponent<Canvas>();
canvas.renderMode = RenderMode.ScreenSpaceOverlay;
canvas.pixelPerfect = true;
}
}
There isn't any class named Panel but instead UnityEngine.UI.Image is used however it cannot be instantiated (protected constructor, WTH?)
What's the best way to create a simple, colored bg rect via script for the Unity UI system?
void Start () {
GameObject newCanvas = new GameObject("Canvas");
Canvas c = newCanvas.AddComponent<Canvas>();
c.renderMode = RenderMode.ScreenSpaceOverlay;
newCanvas.AddComponent<CanvasScaler>();
newCanvas.AddComponent<GraphicRaycaster>();
GameObject panel = new GameObject("Panel");
panel.AddComponent<CanvasRenderer>();
Image i = panel.AddComponent<Image>();
i.color = Color.red;
panel.transform.SetParent(newCanvas.transform, false);
}
this gave me a small red square. How do I get it to cover the screen?
