# Artificial Intelligence
In Common GAS, you can choose the standard `AIModule` when it comes to build an AI system. I already provided you with some helpful `Decorators`and `Tasks` if you using the standard AIModule
In this example, im going to show you the basic setup to get you going.
### Setup
* By Default, CommonGAS already enabled `AIModule`
* 
* For any AI-controlled characters, they need to inherit from `GCCModularPawn`
* Next, you need to make an `AIController` inherit from `GCCModularAIController` to control the AI.
* In the blueprint graph, on `BeginPlay` we simply call the `Run Behaviour Tree` and apply your behaviour tree asset.
* 
* Lastly, in your `pawn` class class default, find `Pawn->Ai Controller Class` and set your AIController to the one we created.
Now, thats the basic setup that should get you going. Have fun building your AIs!
### Tasks
In Common GAS, i have provided you with some useful `Tasks` you can use with GAS to build your gameplay logic:
## BTTask\_ActivateAbilityByClass

## BTTask\_AddLooseGameplayTag
## BTTask\_AddLooseGameplayTags
## BTTask\_ApplyGameplayEffectToSelf
## BTTask\_ApplyGameplayEffectToTarget
## BTTask\_RemoveLoooseGameplayTags
## BTTask\_RemoveLooseGameplayTag
## BTTask\_SendGameplayEvent
### Decorators
In Common GAS, i have provided you with some useful `Decorators` you can use with GAS to build your gameplay logic:
## BTDecorator\_HasAllGameplayTags
## BTDecorator\_HasAnyMatchingGameplayTags
## BTDecorator\_HasMatchingGameplayTag
## BTDecorator\_IsAbilitySystemComponentValid
