What did I do wrong? The behavior tree does not repeat execution. about limboai

Unless update_mode is set to manual, BT is executed every frame. Judging by your screenshots, the PlayerInRange fails, however the MoveToPlayer for some reason is not executed? Could you provide a screenshot for it?

This is MoveToPlayer.

This task will do nothing, because it sets the velocity, then returns SUCCESS, which would be followed by _exit method. And _exit resets the velocity to ZERO.

Exit is always called after the task returns a SUCCESS or FAILURE.

But there is a print() in my tick function, and my Godot doesn't print anything.

Then it's hard to say what is going on. The code looks fine to me, besides the issue I pointed out earlier. Would you like to create a small reproduction project?

Your _tick method is missing delta parameter in the MoveToPlayer task. That's why it's not showing a proper status in the debugger. Not sure why it's not printing an error when the method is called, though. Should be fixed in Godot 4.3 when proper virtual methods are implemented. Currently, GDExtension in the version 4.2 doesn't support marking methods as virtual for Godot API, so we're employing a workaround. That is why the script editor doesn't complain when you define _tick() method without a delta argument. Good news is that it will change with Godot 4.3.

To avoid such issues, I recommend using a script template: you can add it to your project with "Misc->Create script template".

🤣Thx.
