Have you ever had a vehicle or another object that you wanted to travel at a certain speed but didn't know how to work it out? Maybe this thread can help!

This first thing we need to figure out is how tall Sackboy is. How tall Sackboy is will affect all our other calculations.

The smaller you decide Sackboy is the faster Sackboy will need to travel, because an object viewed from a smaller scale will need to traverse more space in order to match the speed of a object viewed at a larger scale.

Let's make Sackboy 150cm tall, so Sackboy matches real-world proportions and we have an easy number to work with. This means that when Sackboy is driving a car at 100mph, it'll look like 100mph as we recognise it.

To work out the speed of an object you'll need to make a track of a certain length, place your object at one end of it and then time how long it takes for your object to make it to the other end. You can use a stopwatch or the in-game race gates to time how long it takes.

If Sackboy is 150cm tall then a level is around 600m (1/3 of a mile) across.

A track 500m long will fit nicely in a level. To make a track this length first make a 4x4 block in small grid mode, make 10 of these and glue them together. You should now have a long rectangular object made of 10 blocks. This object is 15m long (1.5m x 10 = 15m).

You will need to repeat this 15m long object 33 times (15m x 33 = 495m), it might be easier to copy your 15m object 11 times and then copy that twice more to get to 33.

To make up the extra 5m missing from your 495m track make 3 more 4x4 blocks (1.5m x 3 = 4.5m), this will make an object approximately 5m long.

Now that you have a track that is 500m long all you need to do now is place your object at one end and time how long it takes to make it to the other.

35 sec = 50km/h = 30mph

18 sec = 100km/h = 60mph

11 sec = 160km/h = 100mph

1.5 sec = 1200km/h = 750mph (approx. speed of sound)

Using the above table if your object takes 35 seconds to make it to the end of the track then it was travelling at 50 kilometres per hour/30 miles per hour.

Rewind, adjust and repeat as many times as necessary until you get the time/speed you want.

The objects you make for Sackboy to travel in need to be to scale for the sensation of speed to be correct. All numbers in this post are rounded up or down to make them easier to work with.
