The problem triggers here,
File "prueba6.py", line 51, in on_key_release
self.sprite.do(SetImage(spritetoleft))
Action's parameters must be deepcopiable.
A comon workaround is to
- store the no deepcopiable params in the node, like
node.my_param = ...
- In the action .start method use target.my_param to acces the desired
param
