Build a Multiplayer Radar with Player Marker Devices

Imagine you are playing a treasure hunt game. You have a map, but it is blank! You need to see where your friends are hiding. In Fortnite Creative, we can fix this. We will build a radar system. This system will show your friends' positions on the screen. It will even show their health bars. This makes team play much easier.

You do not need to write code for this. We use devices. Devices are like smart tools in your toolbox. They do the work for you. You just connect them. Let’s build a multiplayer radar together.

What You'll Learn

• What a Player Marker device is.
• How to show player health on the screen.
• How to change the look of the marker icon.
• How to test your radar with friends.

How It Works

Think of a Player Marker device as a spy camera. It watches a player. Then, it sends that information to the screen. The screen is called the HUD (Heads-Up Display). The HUD is the part of the screen with your health bar and minimap.

The device has two main jobs. First, it marks the player. This puts a dot on the minimap. Second, it shows extra info. You can choose what extra info to show. You can show health. You can show shield. You can show the distance to that player.

You can also change the look. You can pick a color. You can pick an icon. Maybe you want a red star for enemies. Maybe you want a blue heart for friends. The device lets you customize this.

Let's Build It

We will build a simple team radar. We will mark a "Teammate." We will make their marker green. We will show their health.

Step 1: Place the Device

Open your island in UEFN. Go to the Devices panel. Look for Player Marker. Drag it into your island. Place it near your spawn area.

Step 2: Connect the Player

You need to tell the device which player to watch. Click the device. Look at the properties panel. Find the Target Player setting. Set it to Team 1. This means it will watch any player on Team 1.

Step 3: Choose What to Show

Now, let’s make the marker useful. In the properties panel, find Show Health. Turn this on. Now, when Team 1 players move, you will see their health bar above their head. This is very helpful in fights!

Find Show Shield. Turn this on too. Now you see both health and shield.

Find Show Distance. Turn this on. A number will appear. It tells you how far away the player is. This is great for long-range battles.

Step 4: Customize the Look

Let’s make it look cool. Find Marker Color. Pick Green. This means Team 1 looks friendly. Find Icon. Pick a Heart. Now, a green heart will appear on the minimap for Team 1 players.

Step 5: Test It

Play your island. Join as a Team 1 player. Look at your screen. Do you see the green heart? Do you see the health bar? If yes, you did it! You built a radar.

Here is a visual guide to the settings you will change. This is not code. It is just the settings you click in the editor.

// This is a visual guide for the Player Marker settings.
// You change these in the Properties Panel, not in code.

Device: Player Marker
Settings:
  - Target Team: Team 1
  - Show Health: True
  - Show Shield: True
  - Show Distance: True
  - Marker Color: Green
  - Icon: Heart
  - Show on Minimap: True

Try It Yourself

Now it is your turn to be creative. Change the settings for a different team.

Challenge: Make a marker for Team 2. Make it Red. Make it show only the distance. Do not show health.

Hint: Copy your Player Marker device. Paste it next to the first one. Then change the settings for the new one. Change the Target Team to Team 2. Change the Color to Red. Turn off Health and Shield.

Recap

Player Marker devices are powerful tools. They help players see each other. You can show health, shield, and distance. You can change colors and icons. This makes your island easier to play. Try different settings. Have fun building!
