Cant set my prefab position with Instanciate(Prefab)

I'm trying to create a list of Prefab for my uGUI but when i try to position the prefab it doesnt move to the position at all... if i check in the scene it's at an other place completly... -561, 167, 0 ... how do i move my prefab??

he's a child of the current monobehaviour script.

Code (CSharp):

1.  
2. for (var i = 0; i < SaveGames.Count; i++)
3. {
4.                 var savedGame = Instantiate(SavedGamePanelPrefab);
5.                 savedGame.SetInfos(SaveGames[i]);
6.                 savedGame.transform.parent = _loadMenuPanel.transform;
7.                 var rectTransform = (RectTransform) savedGame.transform;
8.                 rectTransform.localScale = Vector3.one;
9.                 rectTransform.sizeDelta = Vector2.zero;
10.                 rectTransform.anchoredPosition = Vector2.zero;
11.                 rectTransform.position = new Vector3(14, 131 * 75, 0);
12.                 savedGame.gameObject.SetActive(true);
13. }

 

var rectTransform = savedGame.GetComponent<RectTransform>();

The recttransform is not inherently built into "transform", you'll have to manually access it as a component.

 

Nonsense. RectTransform inherits from Transform. So you can access the RectTransform with .transform

To the OP: Setting positions manually for UI elements gets a bit weird. Try setting the position first, before parenting. Then parent with Transform.SetParent and set the second argument to false.

 

Apologies , I have some vague memory of not being able to do that when I first tried the 4.6 gui. Guess I'll be rewriting some of my code.

Also, you might try localPosition with local vectors *after* parenting as well. Both should work.

 

still doesnt work with

Code (CSharp):

1. for (var i = 0; i < SaveGames.Count; i++)
2. {
3.     var savedGame = Instantiate(SavedGamePanelPrefab);
4.     savedGame.SetInfos(SaveGames[i]);
5.  
6.     var rectTransform = (RectTransform)savedGame.transform;
7.     rectTransform.localScale = Vector3.one;
8.     rectTransform.sizeDelta = Vector2.zero;
9.     rectTransform.anchoredPosition = Vector2.zero;
10.     rectTransform.position = new Vector3(14, 131 + (75 * i), 0);
11.     savedGame.transform.SetParent(_loadMenuPanel.transform);
12.     savedGame.gameObject.SetActive(true);
13. }

the position i get is : -563, 9527, 0

prefab default : 0, 0, 0
parent : 227.5, 110.5, 0

EDIT

if i add

rectTransform.localPosition = Vector3.one;

the position i get is : -562, -167

 

See if using .SetParent(_loadMenuPanel.transform, false) helps. The second parameter will make it keep its local position (which you set in the line above it) - the default is to keep the world position instead.

 

Also, in this case, you may sidestep the issue entirely by using a Vertical Layout group on the parent, instead of setting each position by hand. This is what it was made for.

 

i forgot about the false parameter it was written up...

thx a lot to tell it back! it work as expected now.

I will for sure take a look at Vertical Layout for my parent. its surely the UI thing i was looking for!
