My NPC keeps missing the projectile shot because of a player's quick turns and moving on curve circle path

Hello dear Developers! I am here with an issue about my projectile.

My issue is that the NPC, misses the shot at the player, when the player does a quick turn before the NPC throws the ball, and it usually throws the ball on future position of a player, but it becomes inaccurate shot when the player does a quick turn back. NPC, also can miss the shot, when player just moves on a curved circle path on same position, forcing the projectile to go left/right direction which is the “future position of a player”.

I’ve tried to research about how can I make NPC’s reaction time better or how to make NPC check if player will do a quick turn.

Here is my script, how it works.

local npc = script.Parent
local animator = npc.Humanoid.Animator
local animation = animator.BALLTHROW
local loadAnim = animator:LoadAnimation(animation)
local isAnimPlay = false
local npcHum = npc:WaitForChild("Humanoid")

function EnemyNear()
	local nearestPlr = nil
	local shortestDistance = 125

	for _, plr in pairs(game.Players:GetPlayers()) do
		if plr.Character and plr.Character:FindFirstChild("HumanoidRootPart") then
			local distance = (npc.HumanoidRootPart.Position - plr.Character.HumanoidRootPart.Position).magnitude

			if distance <= shortestDistance then
				nearestPlr = plr

				shortestDistance = distance
			end
		end
	end

	return nearestPlr
end

function throw()

	local EnemyPos = EnemyNear()

	if EnemyPos then

		local StartPos = npc.Torso.BallSpawn.Position
		local Root = EnemyPos.Character.HumanoidRootPart

		local t = 1.65
		local EnemyPosNoY = Vector3.new(Root.Position.X, Root.Position.Y, Root.Position.Z)
		local EnemyVelNoY = Vector3.new(Root.AssemblyLinearVelocity.X, 0, Root.AssemblyLinearVelocity.Z)
		local HeightDiff = Root.Position.Y - StartPos.Y
		local HeightFac = 1 + math.max(0, HeightDiff * 0.05)


		local Thrown = EnemyPosNoY + (EnemyVelNoY / t) - StartPos
		local BaseDuration = math.log(1.001 + Thrown.Magnitude * 0.006)
		local Duration = BaseDuration * HeightFac

		StartPos = npc.Torso.BallSpawn.Position + npc.Torso.BallSpawn.AssemblyLinearVelocity * Duration
		Thrown = EnemyPosNoY + (EnemyVelNoY / t) - StartPos

		local Multiplier = 1
		local SuperBallclone = game.ServerStorage["BALL!"]:Clone()
		local Force = Thrown / Duration + Vector3.new(0, workspace.Gravity * Duration * 0.5, 0)
		SuperBallclone.Parent = workspace
		SuperBallclone.Position = StartPos
		SuperBallclone:ApplyImpulse(Force * SuperBallclone.AssemblyMass)
		SuperBallclone:SetNetworkOwner(nil)
		
		local onceHit = false
		
		SuperBallclone.Touched:Connect(function(hit, hum)
			local hitHum = hit.Parent:FindFirstChild("Humanoid")
			
			if hitHum and hitHum ~= npcHum and not onceHit then
				hitHum:TakeDamage(11.00707)
				onceHit = true
				task.wait(1)
				onceHit = false
			end
			
		end)

	end
end

while true do
	
	
	if EnemyNear() then
		loadAnim:Play()
	end
	
	wait(0.4700707)
	throw()
	
	wait(1)
end

Please do not touch the numbers inside of task.wait(), task.wait(0.4700707) is a reference number.
I recommend only checking the throw() function, as it is the function is responsible for projectile’s throw.

Note that I am not a good scripter, and sometimes I cannot some scripts that developers recommend me.

Overall I would like to see not that much of a complicated solution to this issue but rather a slightly understandable solution.

do you want the ball to always hit?

I was about to ask the same thing. OP has encountered an age old problem for all developers. How to make the game difficult enough without cheating. Unfortunately, the only solution is to “cheat” a little. If the NPC is suppose to be “easy”, then there is nothing to change. A quick player can avoid long range shots. But if the NPC is suppose to be “boss” like, then OP is going to need to “cheat” the shots to make them hit more often if the player is not moving around, trying to dodge, etc.

Yes would like to, I would like to make the ball hit the target when they do quick turns.

Hey, me here again! I finally found solution to this problem from my previous forum post!
