# CustomDestroy

### Introduction

CustomDestroy is a method that is called once on every Screen/Entity instance when it is no longer needed. Any objects that are created in custom code (as opposed to objects added through Glue) need to be removed/destroyed in CustomDestroy.

### Example Usage

Objects which are created in CustomInitialize or CustomActivity must be properly destroyed in CustomDestroy. There are two categories of objects which must be destroyed:

1. Entities must have their Destroy method
2. Objects added to the engine (like Sprites) must be removed from the engine

The following example shows a Sprite created in CustomInitialize, then later destroyed in CustomDestroy:

```
// At class scope:
Sprite mSprite;
void CustomInitialize()
{
   mSprite = SpriteManager.AddSprite("redball.bmp", ContentManagerName);
}
// ...
void CustomDestroy()
{
   SpriteManager.RemoveSprite(mSprite);
}
```
