You’ll need a touch screen to test this out.\u00a0 Easiest way is to use the Unity Remote 5 app.\u00a0 It allows you to use your Android device as a touch screen input.<\/p>\n

Start by creating a new empty C# script named “TouchScript” and paste in the following code.<\/p>\n

using System.Collections;\r\nusing System.Collections.Generic;\r\nusing UnityEngine;\r\n\r\npublic class TouchScript : MonoBehaviour {\r\n\r\npublic GameObject bullet;\r\n\r\nvoid Start () {\r\n\r\n}\r\n\r\nvoid Update () {\r\nTouch myTouch = Input.GetTouch (0);\r\nfor(int i =0; i < Input.touchCount; i++)\r\nif (myTouch.phase == TouchPhase.Began) {\r\n{\r\nDebug.Log (\"Touch Position\" + myTouch.position);\r\nSpawnBullet (myTouch);\r\n}\r\n}\r\n}\r\n\r\nvoid SpawnBullet(Touch fireTouch) {\r\nVector3 touchPos = Camera.main.ScreenToWorldPoint (fireTouch.position);\r\ntouchPos.z = 1; \/\/ Puts the z coordinates at 1 so it is visible to the camera.\r\nDebug.Log(\"Vector3 Pos\" + touchPos);\r\nInstantiate (bullet, touchPos, Quaternion.identity);\r\n}\r\n}<\/code><\/pre>\n
Now you’ll need to put your script on a game object.\u00a0 You should be able to drag and drop it on any game object, in this case the Main Camera “green”.<\/p>\n
Next drag and drop the game object prefab to the script “red”.\u00a0 This tells the script which game object to spawn or instantiate when you touch the screen.<\/p>\n
\"\"<\/a><\/p>\n
Run the scene.\u00a0 It should now create a game object where you touch on the screen.<\/p>\n
