How Can I Make My Gun Aim

[Reset4319806 (Triangle)]

I am trying to make a gun framework and cannot work out how to make the gun aim if the player holds right click. i know i need to use UIS/Mouse which i have done but i cant get it to smoothly animate to the aim pos, or even aim at all.

my gun is in

workspace.CurrentCamera

so i am using RenderStepped

How would i do this? i am trying to make the aiming similar to the ones in phantom forces

Aiming down sights

To get our weapon to aim down the sights we will add a small invisible part to our weapon called Aim . We will use this part as a reference to where the weapon should be attached to the head when the player is aiming. Again, we’ll make sure the front face is facing forward and the up face is facing up.

Since we adjusted the C0 value earlier we will make this adjustment in it’s entirety with C1 to avoid overlap.

To start we use the basic equality of joints we can figure out how to pick C1 given that weapon.Handle = joint.Part1 and we’re setting joint.Part1.CFrame = camera.CFrame .

joint.Part0.CFrame * joint.C0 == joint.Part1.CFrame * joint.C1
joint.C1 = joint.Part1.CFrame:inverse() * joint.Part0.CFrame * joint.C0
-- recall though that joint.Part0.CFrame == camera.CFrame, thus:
joint.C1 = joint.C0

Of course we want to further adjust this so the camera focuses on the Aim part, not Handle . So using inverses we can find the offset that would be needed to move from the Handle.CFrame to the Aim.CFrame .

Handle.CFrame * offset = Aim.CFrame
offset = Handle.CFrame:inverse() * Aim.CFrame;

Putting this all together we get:

local aimCount = 0;
local offset = weapon.Handle.CFrame:inverse() * weapon.Aim.CFrame;

local function aimDownSights(aiming)
	local start = joint.C1;
	local goal = aiming and joint.C0 * offset or CFrame.new();
	
	aimCount = aimCount + 1;
	local current = aimCount;
	for t = 0, 101, 10 do
		if (current ~= aimCount) then break; end
		game:GetService("RunService").RenderStepped:Wait();
		joint.C1 = start:Lerp(goal, t/100);
	end
end

local function onInputBegan(input, process)
	if (process) then return; end
	if (input.UserInputType == Enum.UserInputType.MouseButton2) then
		aimDownSights(true);
	end
end

local function onInputEnded(input, process)
	if (process) then return; end
	if (input.UserInputType == Enum.UserInputType.MouseButton2) then
		aimDownSights(false);
	end
end

game:GetService("UserInputService").InputBegan:Connect(onInputBegan);
game:GetService("UserInputService").InputEnded:Connect(onInputEnded);

hmm, time to get to rewriting almost my entire system

[mobyboyy]

Just use the math as a reference for the aiming, not rewrite the entire thing. I quoted the main section you will wanna use.

[mobyboyy]

You can just use this function.

@EgoMoose

local aimCount = 0; 
local offset = weapon.Handle.CFrame:inverse() * weapon.Aim.CFrame; 
local function aimDownSights(aiming)
	local start = joint.C1; local goal = aiming and joint.C0 * offset or CFrame.new(); 
	aimCount = aimCount + 1; 
	local current = aimCount; for t = 0, 101, 10 do
	if (current ~= aimCount) then break; end 							
		game:GetService("RunService").RenderStepped:Wait(); 
		joint.C1 = start:Lerp(goal, t/100);
	end
end

ok, thank you. i will see if it works

[Swatdude22]

whats the joint part supposed to mean, I dont understand.

You can use a ModuleScript and state the AimSpeed, then in a localscript in StarterPlayer you can do:

local aimCF = CFrame.new()
if isAiming and framework.viewmodel ~= nil and framework.module.canAim then
		local offset = framework.viewmodel.AimPart.CFrame:ToObjectSpace(framework.viewmodel.PrimaryPart.CFrame)
		aimCF = aimCF:Lerp(offset, framework.module.aimSpeed)
end
