As you can see, I'm using the following commands, but the gameplay is unsatisfactory and I'm encountering some issues that affect my experience.

Bots will get stuck in the process. Of course, I can enable sm_cvar sb_unstick, but when waiting for the elevator or automatic door, the Bots will be teleported away first. I'm hoping to find a way for Bots to not get stuck on obstacles.
Bots cannot avoid the fire and Spitter's acid until they fall. How should I make them avoid the fire and acid?

I really hope that Bots can play as well as real players, or even better than real players. If there is a more practical method, please tell me!
