Task 3 - CS2 Bot behavior trees

Task assignment

Implement a custom bot behavior using KeyValues3 (KV3), and the behavior must contain the following requirements:

• look at the enemy player if nearby
• run to the enemy player's position right after spawn

This behavior should prevent the enemy T team from going to plant the bomb.

Steps to setup

1. Read the documentation of Bot Behavior Trees
2. Scripts has to be placed in steamapps/common/Counter-Strike Global Offensive/game/csgo
3. Create a folder structure if does not exists scripts/ai/task3
4. In task3 folder create a KV3 file named follow.kv3 and add all of the logic here
5. To run the file use a CS2 console with following commands:

1. run map - game_alias custom; game_mode 0; game_type 3;

map de_dust2; mp_roundtime 60; mp_round_restart_delay 0; mp_freezetime 0; mp_team_intro_time 0; mp_warmuptime 0; bot_join_team T;

2. clear cache - mp_bot_ai_bt_clear_cache
3. apply the script - mp_bot_ai_bt "scripts/ai/task3/follow.kv3"
4. kill all bots to apply the AI script - bot_kill

• mp_respawn_on_death_t 1 - respawn T players on death
• mp_respawn_on_death_ct 1 - respawn CT players on death
