FPS project crashing when launched

[alexpalms]

Description: The FPS game is not able to run, it crashes at this line: https://github.com/edbeeching/godot_rl_agents_examples/blob/5e064c9b7ca619fdee3e69daa16b8c5b31760bb2/examples/FPS/main.gd#L21

with the following output messages:

Expected behavior: Launch the selected game

Steps to reproduce:

• Download this repo
• Launch Godot
• Import FPS godot project file
• Click run button (or F5)

Environment info:

• Windows 10
• Godot 4.0.1
• Using miniconda virtual env system

Additional info:

• Also tried to first run gdrl before launching the game
• Also looked for docs, especially as the introductory tutorial on the RingPong game (https://huggingface.co/learn/deep-rl-course/unitbonus3/godotrl?fw=pt) mentiones it saying:

"This can be a great benefit on more complex environments, like the multi-player FPS we will learn about in the next chapter."

but was not able to find the mentioned chapter.

In addition, I also tried what is described here: https://github.com/edbeeching/godot_rl_agents#quickstart-guide

and more precisely:

• I downloaded the game from hf: gdrl.env_from_hub.exe -r edbeeching/godot_rl_FPS
• Imported the game project file in godot
• run it

But it crashes too, with a different error, as shown by the next image:

Hi thanks for reporting this issue. It appears that some of the IK nodes were changed between Godot 4 beta 14 and Godot 4 stable. I just updated the example, there is still something funky going on with the animations, but it should run now. Let me know of any further issues.

Pulling solved the issue, thanks.
