-		BT composite that executes child tasks from first to last until any child returns [code]SUCCESS[/code]. BTDynamicSelector will execute tasks from the beginning each tick, reevaluating their statuses.
+		BTDynamicSelector executes its child tasks sequentially, from first to last, until any child returns [code]SUCCESS[/code]. Unlike [BTSelector], it will execute tasks from the beginning every tick, reevaluating their statuses. It is quite useful when you want to retry higher-priority behaviors in every tick.
-		Returns [code]RUNNING[/code] if a task returns [code]RUNNING[/code], and remembers last [code]RUNNING[/code] child. In contrast to normal selector, on the next execution tick it will reexecute preceeding tasks and reevaluate their return statuses. If any of the preceeding tasks does not return [code]FAILURE[/code], it will cancel execution of the remembered [code]RUNNING[/code] task.
+		Returns [code]RUNNING[/code] if a child task results in [code]RUNNING[/code]. BTDynamicSelector will remember the last [code]RUNNING[/code] child, but, unlike [BTSequence], on the next execution tick, it will reexecute preceding tasks and reevaluate their return statuses. If any of the preceding tasks doesn't result in [code]FAILURE[/code], it will abort the remembered [code]RUNNING[/code] task.
-		Returns [code]FAILURE[/code] if all tasks return [code]FAILURE[/code].
+		Returns [code]FAILURE[/code] if all child tasks result in [code]FAILURE[/code].
-		Returns [code]SUCCESS[/code] if any task returns [code]SUCCESS[/code].
+		Returns [code]SUCCESS[/code] if a child task results in [code]SUCCESS[/code].

Unlike [BTSequence], it will execute tasks from the beginning every tick, reevaluating their statuses.
