To use the executions timers (to show the elapsed time between a start and a stop node) and to be able to disable all prints (except Errors prints), you need to use the provided BP_LDebugGameInstance, you can either use it as base GameInstance, or reparent it to your own GameInstance. Then define your desired GameInstance in Projet Settings.
By default all levels can be printed, if you want to be able to limit the levels a specific Blueprint can print, you need to implement the interface BPI_LDebug
- Go into your blueprint asset
- Click on Class Settings
- Seek the Interface / Implemented interfaces part on the Details tab, and add the BPI_LDebug
- A new function will be added to your blueprint: GetDebugMask
- You need to create a node Make Bitmask and set the type of enum to ELDebugLevel on the Details tab
- You can click on no flags and check every levels that you want your blueprint to print
