Slow Down the Speedsters: RR EMP Volumes

Do you want to make your Rocket Racing track tricky? You can slow down fast cars with special zones. These zones are called EMP Volumes. They act like invisible speed bumps. Your players will feel the difference when they drive through them. Let’s build a simple race track with these zones.

What You'll Learn

• What an RR EMP Volume is.
• How to place it on your track.
• How to change its shape.
• Why it makes racing more fun.

How It Works

Imagine you are driving a super-fast car. Suddenly, you hit a patch of thick mud. You slow down a lot. The RR EMP Volume does this in the game. It is a special zone for Rocket Racing. When a car drives over it, the car loses speed. This happens automatically. You do not need to write code for this. It is built-in.

This device is only for Rocket Racing islands. It will not work in other game modes. The speed loss is fixed. You cannot change how much speed is lost. This keeps the game fair for everyone. But you can change the shape of the zone. You can make it long and thin. Or you can make it wide and round. This lets you control where the slowdown happens.

Think of it like a "slow zone" sign in a school zone. Cars must go slower there. Your job is to place these zones to make the race exciting. You can put them before sharp turns. Or you can put them in the middle of a straightaway. This challenges your players.

Let's Build It

We will place one EMP Volume on a simple track. This will slow down cars passing through it. Follow these steps in UEFN.

1. Open your Rocket Racing island template.
2. Find the Devices tab in the left panel.
3. Look for the Rocket Racing category.
4. Search for RR EMP Volume.
5. Drag it into your level.
6. Place it on your race track.
7. Use the transform tools to resize it.

Here is a visual guide to what you are doing.

// This is not code, but a visual guide!
// 1. Place the device on the track.
// 2. Make sure the car path goes through it.
// 3. Resize the volume to fit the lane.

// Example of what the device does:
// Car enters zone -> Speed drops -> Car exits zone -> Speed returns

Walkthrough

First, you need the right island. Start with a Rocket Racing template. This gives you the right tools. Next, find the device. It is under Rocket Racing devices. Drag it onto your map. Now, position it carefully. The car must drive through the center of the volume. If the car misses it, nothing happens. Finally, resize the volume. Make it wide enough for the car. But not too wide. You want a precise slowdown.

Try It Yourself

Now it is your turn to experiment. Try placing two EMP Volumes close together. What happens when a car drives through both? Does it stop completely? Or does it just get really slow? Try changing the shape to a long strip. Place it across the whole track. See how this changes the race.

Hint: Think about where you would put a speed bump in real life. You put it where you want drivers to be careful.

Recap

RR EMP Volumes are special zones for Rocket Racing. They slow down cars automatically. You cannot change the speed loss amount. But you can change the shape and placement. Use them to make your track more challenging. Have fun building your race!
