Subsequently, create a separate script for each button and attach it to the corresponding button.\n\nWithin the script, leverage the Unity event system to handle the button click events. In each script, add a public function to process the button's click event and utilize Unity's event system to associate this function with the button's click event.\n\nFor instance, if you have two buttons named "Button1" and "Button2", follow these steps:\n\n1. Create a new script named "Button1Script" and attach it to "Button1". In the script, add a public function named "Button1Click" to handle "Button1"'s click event.\n\ncsharp\nusing UnityEngine;\nusing UnityEngine.UI;\n\npublic class Button1Script : MonoBehaviour\n{\n public Button button1;\n\n void Start()\n {\n button1.onClick.AddListener(Button1Click);\n } \n\n public void Button1Click()\n {\n Debug.Log("Button1 clicked");\n // Add logic for Button1 click event here\n }\n}\n\n\n2. Create a new script named "Button2Script" and attach it to "Button2". In the script, add a public function named "Button2Click" to handle "Button2"'s click event.\n\ncsharp\nusing UnityEngine;\nusing UnityEngine.UI;\n\npublic class Button2Script : MonoBehaviour\n{\n public Button button2;\n\n void Start()\n {\n button2.onClick.AddListener(Button2Click);\n } \n\n public void Button2Click()\n {\n Debug.Log("Button2 clicked");\n // Add logic for Button2 click event here\n }\n}\n\n\n3. Now, regardless of whether you click "Button1" or "Button2", their click events will be triggered simultaneously.\n\nNote: To ensure both buttons can receive click events when overlapping, you may need to adjust their rendering order (by modifying their order in the hierarchy panel) or use the Raycast Target property to control whether they can receive click events.\n
