How to simulate vehicle acceleration ?
Hello! I have a problem trying to simulate vehicle acceleration, I tried doing for i loops
1 | Seat.Changed:Connect(function() |
2 | for currentspeed, 100 do |
3 | wait(1) |
4 | Speed = Speed + 1 |
5 | end |
6 | end) |
or using repeat loop
1 | Seat.Changed:Connect(function(pro) |
2 | local input = Seat.Throttle |
3 | repeat |
4 | wait(.5) |
5 | Speed = Speed + 1 |
6 | until seat.Throttle ~= input |
7 | end) |
Hope you can help! (And thanks for reading :D )

Upvoted, no idea about vehicles lol. Else i'd help I_Nev 200 — 4y

Can you provide a bit more context. What are you doing with the variable 'Speed' other than changing it's value? Are you applying it to the vehicle somehow? Kibloxen 1 — 4y

Yes. I want to make it simple and clear, Speed is just the Vehicle Speed, I will apply it to the vehicle after. Nguyenlegiahung 1091 — 4y

There's a lot of ways you can do this. Easiest way is to simulate a throttle and turn that into RPM. Then you can grab a gear ratio to simulate transmission and turn that into speed. Here's a little script I wrote.
01 | local Throttle = 0 |
02 | local RPM = 0 |
03 | local MaxRPM = 5000 |
04 |
05 | local Speed = 0 |
06 |
07 | local GearRatio = 1/4 --4:1, for every rotation of the wheel, four rotations of the engine were accomplished. don't worry about that too much as we aren't simulating it. |
08 |
09 | for i = 0,1,0.02 do --increase throttle, and calculate speed. |
10 | Throttle = i |
11 |
12 | RPM = MaxRPM*Throttle |
13 | Speed = RPM*GearRatio |
14 |
15 | print(Speed) |
16 | end |
You can simulate fully the real interactions that occur between the throttle (and throttle valve) and the engine, alongside an actual transmission and clutch, and properly turn this all into a rotation velocity, but that's a huge amount of physics (and calculus) and not necessary, I assume.

Oh ok, but how should I apply this to a vehicle ? Nguyenlegiahung 1091 — 4y
