Here is the code for movement toward enemy

//ENEMY
function ENT:ChaseEnemy( pos, options )

	local enemy = self:GetEnemy()
	local options = options or {}
	local path = Path( "Follow" )
	path:SetMinLookAheadDistance( options.lookahead or 300 )
	path:SetGoalTolerance( options.tolerance or 20 )
	path:Compute( self, pos )

	if !enemy:IsValid() then return end
	if enemy:Health() < 0 then return end

	path:Compute( self, pos )

	if ( !path:IsValid() ) then return "failed" end

	while ( path:IsValid() ) do
		path:Update( self )
		path:Draw()


		if enemy and enemy:IsValid() and enemy:Health() > 0 then
			if !self.IsAttacking then
				if self:GetRangeTo( enemy ) < 600 then
					if math.random( 1,500 ) == 5 then
						self:IdleSounds()
					end
				end
			end
		end
		
		if ( self.loco:IsStuck() ) then
			self:HandleStuck()
			return "stuck"
		end
		
		if self:GetVelocity():Length() <= 0 then
			timer.Simple( 2, function()
			path:Compute( self, pos )
			end)
		end
		
			if enemy and enemy:IsValid() and enemy:Health() > 0 then
				if self:GetRangeTo( enemy ) < 25 or self:AttackObject() then
				elseif self:GetRangeTo( enemy ) < 25 or self:AttackDoor() then
				end
			end
		if ( options.maxage ) then
			if ( path:GetAge() > options.maxage ) then return "timeout" end
		end

		if ( options.repath ) then
			if ( path:GetAge() > options.repath ) then path:Compute( self, pos ) end
		end
		coroutine.yield()
	end
	return "ok"
end


function ENT:GetEnemy()
	return self.Enemy
end


function ENT:SearchForEnemy( ents )
	for k,v in pairs( ents ) do
	local enemy = math.random(1,2)
		if enemy == 1 then
			if v:IsPlayer() and v:Alive() then
				self:SetEnemy( v )
				return true
			end
		end
	end
	self:SetEnemy( nil )
	return false
end


function ENT:FindEnemy()
	self:SearchForEnemy( ents.FindByClass( "player_default" ) )
	local players = player.GetAll()
	local entities = {}
	if players != nil then
		table.Add( entities, players )
	end
	self:SearchForEnemy( entities )
end


function ENT:HaveEnemy()

	local enemy = self:GetEnemy()

	if ( enemy and IsValid( enemy ) ) then
		if ( enemy:IsPlayer() and !enemy:Alive() ) then
			return self:FindEnemy()
		elseif ( enemy:IsNPC() and enemy:Health() < 0 ) then
			return self:FindEnemy()
	end
		return true
	else
		return self:FindEnemy()
	end
end


function ENT:SetEnemy( ent )
	self.Enemy = ent
	if ent != nil then
		if !ent:IsValid() then return end
		if ent:Health() < 0 then return end
	end
end

Here is the code for movement

//MOVEMENT
function ENT:RunBehaviour()
	while ( true ) do
	if self:HaveEnemy() then

		local enemy = self:GetEnemy()
		pos = enemy:GetPos()
		if ( pos ) then
			if enemy:Health() > 0 and enemy:IsValid() then
				self.HasNoEnemy = false

				if self:CheckStatus() then
					self:MovementFunctions( self.MoveType, self.WalkAnim, self.Speed, self.WalkSpeedAnimation )
				end
				if ( self.loco:IsStuck() ) then
					self:HandleStuck()
					return "stuck"
				end

				local opts = {	lookahead = 300,
					tolerance = 20,
					draw = false,
					maxage = 1,
					repath = 1	}
				self:ChaseEnemy( pos, opts )
			end
		end
	else
		self.HasNoEnemy = true
		self:IdleFunction()
	end
		coroutine.yield()
	end
end

Does anyone have any idea how to fix this? Its really annoying and I can't find out what is wrong. If I did not provide enough code then I will send the rest its just really large.. The zombie navigates fine but it occasionally gets stuck.

There's a few things you can try.
Basically you'll need to do additional pathing code to get a decent path around corners.

In particular, i used [URL]http://wiki.garrysmod.com/page/CNavArea/GetCenter[/URL] along with a few other bits and pieces to create prediction points that curve around the goal path so it's closer to the center of the nav area it's passing through, but not directly in the center.
Should prevent the bots walking into walls like that.

Thank you! This helps a ton! :)
