How to Make a Manual Transmission Car in Roblox

Introduction

Manual transmission cars are a great way to add realism and complexity to your Roblox games. They allow players to control the car’s speed and torque more precisely, which can lead to more challenging and rewarding driving experiences.

In this tutorial, we’ll show you how to create a manual transmission car in Roblox using Lua scripting. We’ll cover everything from setting up the gears to handling player input.

Setting Up the Gears

The first step is to set up the gears for your car. We’ll be using a simple 5-speed manual transmission, but you can adjust the number of gears to fit your needs.

To create a gear, you’ll need to use the CreateGear() function. This function takes two arguments: the gear ratio and the maximum torque. The gear ratio is the ratio of the output speed to the input speed. The maximum torque is the maximum amount of torque that the gear can handle.

lua
local gear1 = CreateGear(3.5, 500)
local gear2 = CreateGear(2.5, 750)
local gear3 = CreateGear(1.75, 1000)
local gear4 = CreateGear(1.25, 1250)
local gear5 = CreateGear(1.0, 1500)

Handling Player Input

Once you’ve set up your gears, you’ll need to handle player input to shift gears. You can use the KeyDown() and KeyUp() functions to detect when the player presses or releases a key.

Here’s an example of how to handle player input for shifting gears:

lua
KeyDown(“W”, function()
if gear < 5 then gear = gear + 1 end end) KeyUp("W", function() if gear > 1 then
gear = gear – 1
end
end)

Applying Gear Changes

Once you’ve detected player input for shifting gears, you’ll need to apply the gear changes to the car. This can be done by setting the GearRatio property of the car’s transmission.

Here’s an example of how to apply gear changes:

lua
function UpdateCarGear()
car.Transmission.GearRatio = gears[gear]
end

Conclusion

That’s it! You now know how to create a manual transmission car in Roblox. With a little practice, you’ll be able to create realistic and challenging driving experiences for your players.
