Returns the Itemobject of a given CollectibleID.

???- example "Example Code" This Code gets the highest possible collectibleid including modded items. It uses the Binary Search algorithm to do it. Using GetCollectible(): (**recommended!**)

```lua
    function GetMaxCollectibleID()
    local id = CollectibleType.NUM_COLLECTIBLES-1
    local step = 16
    while step > 0 do
    if Isaac.GetItemConfig():GetCollectible(id+step) ~= nil then
    id = id + step
    else
    step = step // 2
    end
    end

    return id
    end
```

````
Using GetCollectibles(): (**Crashes on Mac OS)**
```lua 
function GetMaxCollectibleID()
return Isaac.GetItemConfig():GetCollectibles().Size -1
end

```

### GetCollectibles () {: aria-label='Functions' }

[ ](/ab_p/beta/docs/itemconfig_config.md){: .abp .tooltip .badge }

#### ItemList GetCollectibles ( ) {: .copyable aria-label='Functions' }

Returns the List of all Collectibles.

???- example "Example Code" This Code gets the highest possible collectibleid including modded items.

```lua
    function GetMaxCollectibleID()

    end
```
