# Note for the reader:

|
|
# This demo conveniently uses the same names for actions and for the container nodes
|
|
# that hold each remapping button. This allow to get back to the button based simply
|
|
# on the name of the corresponding action, but it might not be so simple in your project.
|
|
#
|
|
# A better approach for large-scale input remapping might be to do the connections between
|
|
# buttons and wait_for_input through the code, passing as arguments both the name of the
|
|
# action and the node, e.g.:
|
|
# button.connect("pressed", self, "wait_for_input", [ button, action ])
