Im trying to make a tool that faces a cylinder in the direction the mouse faces. Problem is the aim is messed up depending on where its fired. Instead of being directly on the mouse its sorta just going in the direction.
Code:
RunServ.Heartbeat:Connect(function()
if firing and hitbox then
hitbox.CFrame = CFrame.new(char.HumanoidRootPart.CFrame.Position, mouse.Hit.Position) * CFrame.new(0,0, - hitbox.Size.X/2) * CFrame.Angles(0,math.rad(90),0)
end
end)
It looks like the cylinder is small. The distance from your character to Mouse.Hit is much larger than the length of your cylinder, giving the illusion that Mouse.Hit is inaccurate.
Yep it’s an illusion, here is the problem mathematically.
This is the perceived inaccuracy.
This is the trigonometric diagram
It’s caused because the cylinder hitbox is too short it’s not able to reach the mouse hit position as @Brickman808 said. The multiple options, one is to decrease the mouse.Hit default length of 1000 studs by creating a custom mouse function like the below
local userInput = game:GetService("UserInputService")
local Mouse = {}
local RAY_DISTANCE = 1000 -- default ray distance like mouse.Hit
local cam = workspace.CurrentCamera
function Mouse.HitPosition(raycastParams, distance)
local mousePos = userInput:GetMouseLocation()
local viewportMouseRay = cam:ViewportPointToRay(mousePos.X, mousePos.Y)
local rayCastResult = workspace:Raycast(viewportMouseRay.Origin, viewportMouseRay.Direction * (distance or RAY_DISTANCE), raycastParams)
local hitPosition
if rayCastResult then
hitPosition = rayCastResult.Position
else
hitPosition = viewportMouseRay.Origin+viewportMouseRay.Direction * (distance or RAY_DISTANCE)
end
return hitPosition
end
return Mouse
second option is to rotate it further, and the third is to increase the length of the cylinder hitbox.
I believe the first option is the easiest one just adjust the length until it looks good.
