1) Tall grass can block the enemy's sight,
2) It can be used as a prop and thrown to different places,
3) It can be obtained by gathering or purchasing in the store,
Some players suggested the way of sneaking and attacking in the grass. The developers also want to make the game more interesting, so they add some function development, hoping to make it more fun.
I use behavior trees to make enemy AI. The behavior tree method is more organized and has good effects. Now I need to modify the see node or add some nodes.
