# Enhanced Input
### AddInputMappingContexts
Apply multiple Input Mapping Contexts.
```cpp theme={null}
AController* PlayerController = GetPlayerController();
TArray Contexts; // Fill with the desired contexts
bool bClearPrevious = false;
EUDSuccessStatus ReturnValue = UUDCoreInputFunctionLibrary::AddInputMappingContexts(PlayerController, Contexts, bClearPrevious);
```
**Inputs**
The player controller to add the contexts to. Will attempt to get the LocalPlayer from the controller.
The contexts to apply.
Whether to clear all previous contexts before applying the new ones.
**Outputs**
Returns Success if the contexts were successfully applied.
### RemoveInputMappingContexts
Remove multiple Input Mapping Contexts.
```cpp theme={null}
AController* PlayerController = GetPlayerController();
TArray> Contexts; // Fill with the desired contexts
EUDSuccessStatus ReturnValue = UUDCoreInputFunctionLibrary::RemoveInputMappingContexts(PlayerController, Contexts);
```
**Inputs**
The player controller to remove the contexts from. Will attempt to get the LocalPlayer from the controller.
The contexts to remove.
**Outputs**
Returns Success if the contexts were successfully removed.
### SwapInputMappingContexts
Swap a designated Input Mapping Context with a new one.
```cpp theme={null}
AController* PlayerController = GetPlayerController();
TSoftObjectPtr PreviousContext; // The context to swap out
TSoftObjectPtr NewContext; // The context to swap in
int32 Priority = 0;
bool bUsePreviousPriority = false;
EUDSuccessStatus ReturnValue = UUDCoreInputFunctionLibrary::SwapInputMappingContexts(PlayerController, PreviousContext, NewContext, Priority, bUsePreviousPriority);
```
**Inputs**
The player controller to swap the contexts on. Will attempt to get the LocalPlayer from the controller.
The context to swap out.
The context to swap in.
The priority to set the new context to.
Whether to use the previous context's priority when adding the new context.
**Outputs**
Returns Success if the contexts were successfully swapped.
