You're right, Chris. I finally managed to make it work by following this tutorial https://adventurecreator.org/tutorials/creating-inventory-bar-unity-ui. First time making Unity UI so I still don't know how things work. Thanks for the support!
Change the Walk speed scale seems a better choice in my case. Also great to know other options. They would fit into different situations.
Thanks a lot, Chris!
It's like an interaction to push back the NPC so I can't use Keep out of Player's way.
Btw, the engine is awesome for an artist with no knowledge of coding like me. Really appreciate you creating it.
