I need to instantiate a prefab inside canvas, already tried several solutions but none worked. Can you help? But did not worked either. The prefab instance initiates outside canvas.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. My scene has basic game objects camera, canvas with two child image and button.
I make a prefab of a button, now the prefab is on the project view, I want to instantiate this prefab button from within the script, and I want it to be drawn inside the canvas. For that, I make a script file, attach it to the canvas as a script component.
Here is my script implementation:.Affidabilita dei sistemi stocastici (semplici)
Of course, the suggestionBtn is the prefab, that's why I make a reference of it to the script variable drag the prefab from the project view to the script component.
Now when I run the game, I noticed the clone of the prefab is added above all game objects in the hierarchy view I am expecting to get it added inside the canvas :. And also it has wrong dimension very very small, it is barely visiblehere how it looks after I zoom it in. So my question is how can I instantiate the prefab correctly with its normal size and position it correctly relatively to the canvas child of the canvas?
You can correctly initialize the transform under correct game object hierarchy by assigning the instance to a variable and then changing its parent.
You can change the localScale from the assigned clone variable after instantiation. From your screenshot of the hierarchy view at runtime, your instantiated button is not nested under the Canvas, therefore it will not be rendered by the Canvas Renderer. When you instantiate it, you need to set the transform. Learn more. Instantiate method doesn't draw the prefab button inside the canvas and doesn't draw it with correct prefab dimensions Ask Question.

Prefabs come in very handy when you want to instantiate complicated GameObjects at runtime.
The alternative to instantiating Prefabs is to create GameObjects from scratch using code. Instantiating Prefabs has many advantages over the alternative approach:. If you execute that code, you will see an entire brick wall is created when you enter Play mode.
There are two lines relevant to the functionality of each individual brick: the CreatePrimitive line, and the AddComponent line. Not so bad right now, but each of our bricks is un-textured.
Every additional action to want to perform on the brick, like changing the texture, the friction, or the Rigidbody massis an extra line.Wksr news pulaski tn menu
If you create a Prefab and perform all your setup before-hand, you use one line of code to perform the creation and setup of each brick. This relieves you from maintaining and changing a lot of code when you decide you want to make changes.
With a Prefab, you just make your changes and Play. No code alterations required. This is not only very clean but also very reusable. There is nothing saying we are instantiating a cube or that it must contain a rigidbody. All of this is defined in the Prefab and can be quickly created in the Editor. When you select the empty GameObject that contains the script, the Brick variable will be visible in the inspector.
This is a workflow pattern that can be used over and over again in Unity. In the beginning you might wonder why this is so much better, because the script creating the cube from code is only 2 lines longer.
But because you are using a Prefab now, you can adjust the Prefab in seconds. Want to change the mass of all those instances? Adjust the Rigidbody in the Prefab only once. Want to use a different Material for all the instances? Drag the Material onto the Prefab only once. Want to change friction? Want to add a Particle System to all those boxes? Add a child to the Prefab only once.Thank you for helping us improve the quality of Unity Documentation.

If you are cloning a GameObject you can specify its position and rotation these default to the original GameObject's position and rotation otherwise. If you are cloning a Component the GameObject it is attached to is also cloned, again with an optional position and rotation.
Instantiate a prefab in canvas
When you clone a GameObject or Componentall child objects and components are also cloned with their properties set like those of the original object. By default the parent of the new object is null; it is not a "sibling" of the original.
However, you can still set the parent using the overloaded methods. If a parent is specified and no position and rotation are specified, the original object's position and rotation are used for the cloned object's local position and rotation, or its world position and rotation if the instantiateInWorldSpace parameter is true.
If the position and rotation are specified, they are used as the object's position and rotation in world space.
The active status of a GameObject at the time of cloning is maintained, so if the original is inactive the clone is created in an inactive state too. Additionally for the object and all child objects in the hierarchy, each of their Monobehaviours and Components will have their Awake and OnEnable methods called only if they are active in the hierarchy at the time of this method call.
These methods do not create a prefab connection to the new instantiated object. Creating objects with a prefab connection can be achieved using PrefabUtility. Instantiate can be used to create new objects at runtime. Examples include objects used for projectiles, or particle systems for explosion effects. Instantiate can also clone script instances directly. The entire game object hierarchy will be cloned and the cloned script instance will be returned.
After cloning an object you can also use GetComponent to set properties on a specific component attached to the cloned object. You can also use Generics to instantiate objects.
See the Generic Functions page for more details. Is something described here not working as you expect it to? It might be a Known Issue. Please check with the Issue Tracker at issuetracker.

Creating equivalent GameObjects from scratch requires many more lines of code.

Note : You can download a Unity Project containing all the examples on this page, here:.
To instantiate a Prefab at run time, your code needs a reference to that Prefab. You can make this reference by creating a public variable in your code to hold the Prefab reference. The public variable in your code appears as an assignable field in the Inspector.
You can then assign the actual Prefab you want to use in the Inspector. It creates an instance of that Prefab in the Start method. Create any Prefaband drag it from the Project window into the My Prefab field in the script component. When you start Play Mode, you should see your Prefab instantiate at position 0, 0, 0 in the Scene A Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces.
You can drag a different Prefab into the My Prefab field in the Inspector to change which Prefab is instantiated, without having to change the script. Because this first example is very simple, it may not seem to provide any advantage over just placing a Prefab into the Scene yourself.
However, being able to instantiate Prefabs using code provides you with powerful abilities to dynamically create complex configurations of GameObjects while your game or app is running, as shown in the following examples. To illustrate the strength of instantiating Prefabs at run time, here are some basic situations where they are useful:. Building a structure out of a single Prefab by replicating it multiple times in different positions, for example in a grid or circle formation.

The heartcontainter should be added to the healthbar, the heart is a child of the heartcontainer and is set to stretch it should be the same size as its parent.
You fix this by pass false to the second parameter of the SetParent function. By doing this, you will make the Transform keep its local orientation rather than its global orientation. You can also set the parent Object and make the instantiated Object's Transform keep its local orientation in the Instantiate function. The only disadvantage of this is that you now have to set the position of object in another line of code instead of the Instantiate function like before.

No worries. I won't downvote you or anything, just thought you'd be better off on a more specific forum. Good luck! This question is valid here. What is the problem and what is the question?

Simply replace : newHealthContainerTransform. SetParent healthBar, false You can also set the parent Object and make the instantiated Object's Transform keep its local orientation in the Instantiate function.
Programmer Programmer 91k 14 14 gold badges silver badges bronze badges.The Boss prefab is instantiated from another script; in its start method, it instantiates the BossHealth prefab a UI Text element. I know that the BossHealth prefab being a UI element should be instantiated as a child of a canvas and I attempt to make that happen in BossHealth's start method. I have a canvas in the scene named Canvas.
In the Inspector, I've set the public GameObject references they're notated here in my code for clarity.
Instantiating prefab with canvas
For what it's worth, the canvas itself was not modified in any way from its default, except that I added three UI prefab children to it but not the BossHealth prefab, as I want that to be instantiated from a script. It has to be a game object already existing in your scene maybe an instantiation of your prefab canvas. Find to search for the instantiated canvas once it exists. Or, as a canvas takes little resources on its own, just leave the canvas in the scene so you can still use your public statement.
