【L4D2】How to improve the wisdom of Survivor Bots?
 

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.

sm_cvar sb_l4d1_survivor_behavior 1
sm_cvar sb_allow_leading 1
sm_cvar sb_max_team_melee_weapons 4
sm_cvar sb_all_bot_game 1
sm_cvar allow_all_bot_survivor_team 1
sm_cvar sb_stop 0
sm_cvar sb_escort 0
sm_cvar sb_unstick 0
sm_cvar sb_allow_shoot_through_survivors 0
sm_cvar sb_battlestation_human_hold_time 2
sm_cvar sb_sidestep_for_horde 1
sm_cvar sb_toughness_buffer 40
sm_cvar sb_temp_health_consider_factor 0.75
sm_cvar sb_friend_immobilized_reaction_time_normal 0.001
sm_cvar sb_friend_immobilized_reaction_time_hard 0.001
sm_cvar sb_friend_immobilized_reaction_time_expert 0.001
sm_cvar sb_friend_immobilized_reaction_time_vs 0.001
sm_cvar sb_separation_range 150
sm_cvar sb_separation_danger_min_range 150
sm_cvar sb_separation_danger_max_range 600
sm_cvar sb_transition 0
sm_cvar sb_close_checkpoint_door_interval 0.25
sm_cvar sb_max_battlestation_range_from_human 200
sm_cvar sb_battlestation_give_up_range_from_human 500
sm_cvar sb_close_threat_range 250
sm_cvar sb_threat_close_range 250
sm_cvar sb_threat_very_close_range 250
sm_cvar sb_threat_medium_range 500
sm_cvar sb_threat_far_range 1000
sm_cvar sb_threat_very_far_range 2000
sm_cvar sb_neighbor_range 200
sm_cvar sb_follow_stress_factor 100
sm_cvar sb_locomotion_wait_threshold 2
sm_cvar sb_path_lookahead_range 1000
sm_cvar sb_near_hearing_range 1000
sm_cvar sb_far_hearing_range 2000
sm_cvar sb_combat_saccade_speed 2000
sm_cvar sb_max_scavenge_separation 1500

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!

There's no other (properly working) way other than making changes to the behaviors in their behavior tree. I have some plugins on my GitHub that address some issues, even an extension that improved their overall behavior but it's abandoned. Nonetheless, it's still a great source for fixing some of their most annoying issues.

Hey, what do your plugins do? Can you share it?
