Unity automatically clicks the Canvas

foreword

When encountering an item that does not require a mouse, you can use the following methods to directly trigger UI button events

source code

Pressing Qcan trigger the button event at the corresponding position under the UI

Tip: It needs to be mounted on a device with GraphicRaycastercomponentsCanvas

public class TestClickCanvas: MonoBehaviour
{
    
    
    GraphicRaycaster raycaster;
    
    void Start()
    {
    
    
        raycaster = GetComponent<GraphicRaycaster> ();
    }
    
	private void Update()
    {
    
    
        if (Input.GetKeyDown(KeyCode.Q))
        {
    
    
            PointerEventData pointerData = new PointerEventData(EventSystem.current);
            List<RaycastResult> results = new List<RaycastResult>();
            //想要点击的位置
            pointerData.position = new Vector2(0,1080);
            raycaster.Raycast(pointerData, results);
            foreach (RaycastResult result in results)
            {
    
    
                Debug.Log("Hit " + result.gameObject.name);
                if (result.gameObject.GetComponent<Button>()!=null)
                {
    
    
                	//触发事件
                    result.gameObject.GetComponent<Button>().onClick.Invoke();
                }
            }
        }
    }
}
