Prefab Instantiation around the main Game Object in Unity. The main issue is that I am creating a prefab (TextPrefab) that only contains a TextMeshPro - Text (UI). In my spawning script, when my controller component calls to Instantiate the prefab, I'm getting the following console error: NullReferenceException: Object reference not set to . To solve this issue, we can specify a parent simply by passing in the transform of the object we want to be the parent. Instantiating Linked Prefabs in the Unity Editor.

In terms of workflow, you just made a clone. Unity ID. . Notice the Canvas_child Prefab instance scale is now 0,0,0 6. We do not support spawning nested NetworkObjects at runtime. The string names are the prefab names. GameObject enemy = Instantiate (enemyPrefab, new Vector3 (0, 0, 0), Quaternion.identity) as GameObject; enemy.transform.SetParent (GameObject.FindGameObjectWithTag ("Canvas").transform, false); Setting parent is done with transforms of two objects. We can simplify the code to this: In this tutorial we are creating a simple shooting game with bullet as prefab which is instantiated when spacebar is hit, and by default it travels towards right direction at a set speed.

Other simple way to solve this issue without creating empty parent game object: GameObject pc = (GameObject) Instantiate (Prefab, position, rotation, transform); pc.transform.Rotate (new Vector3(rotationWished.x,rotationWished.y,rotationWished.z)); Where you choose in Vector3 rotationWished which . So if you need prefabs, or any kind of objects we want to add to our game run time at a certain time this is the method for you. Thank you!
