+		Base class for all actions within a [BehaviorTree]. You can create your own actions by extending the [BTAction] class.
 		Represents a specific behavior or action in a [BehaviorTree] that an agent should execute. Actions are the lowest level of the [BehaviorTree] hierarchy and are responsible for performing the actual work required to achieve a goal. Actions do not have child tasks.
 		A single action can perform a task within one or multiple ticks. If it takes more than one tick to complete the task, the action should return [code]RUNNING[/code] status. When the task is finished, the action returns either [code]SUCCESS[/code] or [code]FAILURE[/code] to indicate the outcome.

+		Base class for all [BehaviorTree] conditions. You can create your own conditions by extending the [BTCondition] class.
 		Condition is a task within a [BehaviorTree] that checks for a specific condition before executing subsequent tasks. It is often used inside composite tasks to control the execution flow. Conditions are used to verify the state of the environment, check for the presence of an enemy, or evaluate the health status of the agent. The use of condition tasks in a [BehaviorTree] can improve system efficiency and prevent unnecessary actions. However, they may not be suitable for complex decision-making processes, and too many condition tasks can make the [BehaviorTree] difficult to read.
 		Conditions typically don't take multiple ticks to finish and return either [code]SUCCESS[/code] or [code]FAILURE[/code] immediately.

 		Base class for all [BehaviorTree] tasks. A task is a basic building block in a [BehaviorTree] that represents a specific behavior or control flow. Tasks are used to create complex behaviors by combining and nesting them in a hierarchy.
 		A task can be one of the following types: action, condition, composite, or decorator. Each type of task has its own corresponding subclass: [BTAction], [BTCondition], [BTDecorator], [BTComposite].
 		Tasks perform their work and return their status using the [method _tick] method. Status values are defined in [enum BT.Status]. Tasks can be initialized using the [method _setup] method. See also [method _enter] & [method _exit].
