# Post Build Events

Post Build Events\` are executed on a buildable once it has been placed. This allows you to implement any additional logic that should occur after a buildable is created. If you need to add extra functionality to the creation process, this is where you should do it.

To create your own post-build event logic, subclass the `UBF_BuildableCondition` class. Then, in the graph, right-click to find the `Execute Event` node, and add the logic you want to execute upon buildable placement
