How do I unload current prefabs

Hi,

I have written the following;

Code (CSharp):

1. public void LoadBuildingCards()
2. {
3. List<BuildingTypeData> types = BuildingManager.GetInstance().GetAllBuildingTypes().ToList();
4. buildingSelectPanels = new List<UIBuildingSelectView>();
5. foreach (BuildingTypeData type in types)
6. {
7. if (type.BuildingCategory == SelectedCategory)
8. {
9. AddBuildingPanel(type);
10. }  
11. }

Code (CSharp):

1.         private void AddBuildingPanel(BuildingTypeData type)
2.         {
3.             GameObject panelGo = (GameObject)Instantiate(buildingPanelPrefab);
4.             UIBuildingSelectView panel = panelGo.GetComponent<UIBuildingSelectView>();
5.             panelGo.transform.SetParent(buildingScrollPanel.transform);
6.             panelGo.transform.localScale = Vector3.one;
7.             panel.InitialiseWithBuildingType(type);
8.             buildingSelectPanels.Add(panel);
9.         }

The code is working exactly how I want it to, as my interface uses tabs which set the building category (SelectedCategory) and load the prefabs with the buildings required.

My question is that when I click a tab to show military buildings for instance, i need it to remove all the current prefabs that are being shown and then do this code. How do I achieve this?

 

Best pratice is to pre-populate the UI, and then simply gameObject.SetActive(true/false) them when it's needed.

If you're 100% want to unload, use Destroy(*prefab_gameObject*) to do that.

 

The prefab that i use is called UIBuildingSelectPanel, but when I call Destroy(UIBuildingSelectPanel) I get the following error;

CS0118: is a 'type' but a 'variable' was expected.
CS0119: Expression denotes a 'type', where a 'variable', 'value' or 'method group' was expected.

 

You need to specify an actual that prefab's instance gameObject, in order to destroy it. Not a name of it.

Code (CSharp):

1. GameObject someInstance = Instantiate(SomePrefab);
2.  
3. // To destroy, you have to do Destroy on the
4. Destroy(someInstance);

So, in order to do that, you should keep the reference after the instantiation.
