Trace Generation When Using Basket as Goal

[Ayush8120]

Hi,

Thank you for open sourcing this awesome work! I've been playing around with the environment code recently. I wanted to generate trace trajectories when I use a basket ball instead of a red ball as target and basket instead of green star as goal.

However, upon adding these parameters in the custom_level.json file I get the error that "pygame.Surface objects cannot be pickled".

Furthermore, If I run the levels that have basket or basket ball as goal/target then also I am unable to create traces (same error). They run fine without creating traces.

Please let me know if there's any way to get traces while using basket/basetball as goal/target. Any help to understand the underlying issue would be much appreciated :-)

Thanks in Advance!
