BT composite that chooses a child task to execute based on attached probabilities. BTProbabilitySelector chooses a child task to execute based on attached probabilities. It is typically used for decision-making purposes. Probability distribution is calculated based on weights assigned to each child task. Returns [code]SUCCESS[/code] when a child task results in [code]SUCCESS[/code]. Returns [code]RUNNING[/code] when a child task results in [code]RUNNING[/code]. The behavior of BTProbabilitySelector when a child task results in [code]FAILURE[/code] depends on the [member abort_on_failure] value: - If [member abort_on_failure] is [code]false[/code], when a child task results in [code]FAILURE[/code], BTProbabilitySelector will normalize the probability distribution over the remaining children and choose a new child task to be executed. If all child tasks fail, the composite will return [code]FAILURE[/code]. - If [member abort_on_failure] is [code]true[/code], when a child task results in [code]FAILURE[/code], BTProbabilitySelector will not choose another child task to be executed and will immediately return [code]FAILURE[/code]. Returns the child task's selection probability. Returns the total weight of all child tasks. Returns the child task's weight within the weighted probability selection algorithm. Returns whether the child task at index [param p_index] participates within the weighted probability selection algorithm and has a probability assigned to it. Returns [code]false[/code] for [BTComment] tasks. Sets the child task's weight calculated based on the desired probability. Sets the child task's weight for the weighted probability selection algorithm. If [code]true[/code], BTProbabilitySelector will not choose another child to execute and will return [code]FAILURE[/code] when a child task results in [code]FAILURE[/code].
