Question about the timing of binding the BTCallMethod parameter

[youer0219]

Does BTCallMethod fix the parameter values at initialization, rather than dynamically retrieving them each time it is executed?

The lateral_direction in the diagram is fixed at the initial value in the blackboard when the BTCallMethod parameter is passed, even if the lateral_direction was modified in the previous node.

By the way, perhaps we should add a "AI" tag so that this result can come out prioritized when we search for "Godot AI". Maybe very few people will type out the full name of "AI" when they are looking for the AI behavior tree plugin.

Parameters are evaluated on _tick(). So something else might be going wrong here. Try debugging with a custom task:

extends BTAction
func _tick(delta):
    blackboard.print_state()
    return SUCCESS

Insert it before CallMethod under a Sequence composite.

Thanks for your reply!
Through your method, I found out that I set the wrong variable name, it creates a new blackboard variable and modifies it normally. This caused that variable I was referencing on the BTCallMethod node not to get modified correctly.
This is not an issue with BTCallMethod.
