* This allows [custom behaviors](http://wiki.compilgames.net/doku.php/gdevelop5/behaviors/events-based-behaviors), that you can create in your project or get from extensions, to require the presence of one or multiple other behaviors on an object. * This is an advanced feature that is helpful to create behaviors that are based on other. For example, a behavior "Platformer enemy" using the "Platformer object" behavior and adding specific actions, conditions and logic to make an enemy chase the player. * If you create a behavior and want to use this, just go to the properties of this behavior and add a new property. Choose the type "Required Behavior" for this property. You can then use this new behavior in the events of the behavior you just edited. * To use a behavior based on another, you don't need to do anything special! Just add it to your object as usual: any missing behavior will be added to your object, so you can start using it immediately.
