Inventory Items and Gameplay Flags
|

==================================

|
# How do I manage inventory items and gameplay flags?
|
||
|
|
|
||
|
|
1. Use the [SetValue](@ref Fungus.GameController.SetValue) command to record a collected inventory item or gameplay flag.
|
||
|
|
2. Use the [GetValue](@ref Fungus.GameController.GetValue) command to check how many items of that type have been set.
|
||
|
|
3. Use the [HasValue](@ref Fungus.GameController.HasValue) command to check if any items of that type have been set.
|
||
|
|
4. Use the [ClearValue](@ref Fungus.GameController.HasValue) command to reset item count to 0.
