Worked in an 8-people team at Lilith Games from Mars 2021 to July 2021.

Behavior Tree for animal AI

· Behavior Tree contains Sequence, Selector, Condition, Decoration.

· Designer designed animals' behavior. I broke the behavior mode into behavior tree diagram.

Other programmer can create behavior nodes by my codes.

function BTMgr.CreateSequence(_name,_owner)
	local newNode = CreateNewNode()
	newNode:Init(_name, newNode.Type.Sequence,_owner)
	return newNode
end

function BTMgr.CreateSelector(_name,_owner)
	local newNode = CreateNewNode()
	newNode:Init(_name, newNode.Type.Selector,_owner)
	return newNode
end

function BTMgr.CreateAction(_name,_action,_owner,...)
	local args = {...}
	local newNode = CreateNewNode()
	newNode:Init(_name, newNode.Type.Action,_owner,args)
	newNode:SetAction(_action)
	return newNode
end

Different types of anmial FSM inherited from base FSM.

· The game has many types of animals: bird, herbivore, carnivore, etc. So I made modules for different types of animal FSM, which improves code efficiency and work efficieny.

Cooperated with other programmers to build path finding system.

· Understood the basic tool of pathfinding produced by the engine and taught other programmers.

· Wrote interfaces of pathfinding in different situations for animal ai, such as animal being chased. ## Contributed Design to camera system and photo editing system. Built these two systems and made them very customizable for designers.

· The customizable camera and photo system includes filter, sticker, selfi gesture, etc.
