functions

functions	parameter	describe
transform:GetText(string)	Name of child to be found. return: UnityEngine.UI.Text	Get the UnityEngine.UI.Text of the child object through the path
transform:SetTxt(string,string)	1.Name of child to be found. 2.value	Get the UnityEngine.UI.Text of the child object through the path, and then set the string value, if the found object does not have this component, the setting will fail
transform:SetTxt(GameObject,string)	1. UnityEngine.UI.Text 2.value	Setup will fail if GameObject does not contain UnityEngine.UI.Text
transform:GetImage(string)	1.Name of child to be found. return: UnityEngine.UI.Image	Get the UnityEngine.UI.Text of the child object through the path
transform:SetImage(string,sprite)	1.Name of child to be found. 2.UnityEngine.Sprite
transform:SetImage(Image,sprite)	1.UnityEngine.UI.Image 2.UnityEngine.Sprite
transform:SetImage(GameObject,sprite)	1.UnityEngine.GameObject 2.UnityEngine.Sprite	Setup will fail if GameObject does not contain UnityEngine.UI.Image
transform:UIroot()	return：UnityEngine.Transform	ui root node. it's a canvas
