A good way to make a locust game in Roblox is to build it like an insect survival or swarm game: create a locust NPC, make it move with pathfinding, add spawning waves, and give players a simple goal like survive, collect, or grow. Roblox’s PathfindingService is the core tool for moving NPCs around obstacles, and Roblox Studio tutorials on enemy spawners and wave systems fit this style well.

Core idea

Start by deciding what “locust game” means in your game. Two common versions are:

  • A survival game where locusts attack players in waves.
  • A growth game where players become locusts, eat things, and get stronger.

The first version is easier to build because it mostly uses NPC spawning, pathfinding, and damage logic. Roblox Creator Hub’s pathfinding docs explain that pathfinding moves a character logically around obstacles to reach a destination.

Simple build plan

  1. Create a locust model in Roblox Studio.
  2. Put it in ReplicatedStorage.
  3. Add a spawner part in the map.
  4. Script the spawner to clone locusts at intervals.
  5. Use PathfindingService so locusts chase players or move to targets.
  6. Add health, damage, and win/lose conditions.

Enemy spawner tutorials commonly use a pattern where the script clones a model from ReplicatedStorage and places it at a spawn part, which is a clean starting point for a locust swarm game.

Basic swarm behavior

For a swarm feel, make locusts:

  • Spawn in groups instead of one at a time.
  • Target the nearest player.
  • Deal small damage repeatedly.
  • Move with slight randomness so they do not look robotic.

A pathfinding NPC tutorial shows the standard setup of building an NPC, defining waypoints or targets, and using PathfindingService to move around obstacles. That same structure works well for locusts if you want them to chase players.

Example script idea

Here is the basic logic you would combine:

  • A spawner script that clones locusts from ReplicatedStorage.
  • A chase script inside the locust that finds the nearest player.
  • Pathfinding to reach that player.
  • A damage check when the locust gets close.

Conceptually, your loop looks like this:

  1. Spawn locust.
  2. Find nearest player.
  3. Compute path.
  4. Move along path.
  5. Damage on contact.
  6. Repeat.

Design choices

You can make the game feel more fun by choosing one of these styles:

  • Survival: players hold out against endless locust waves.
  • Defense: players protect crops, a base, or a village.
  • Collection: players gather food while locusts chase them.
  • Transformation: players start as humans and turn into locusts.

A wave system is a strong match if you want escalating difficulty, since wave spawner tutorials are built around spawning enemies in increasing rounds.

Safer direction

If by “locust game” you mean a horror or bug-themed Roblox game, keep it focused on game mechanics rather than exploiting or script abuse. The Roblox scripting results I found about “locust scripts” are exploit-related, which is not the right direction for building a real game.

Practical starter setup

Use this order:

  • Make one locust model first.
  • Test movement.
  • Add chasing.
  • Add spawner waves.
  • Add UI and scoring last.

That keeps the project manageable and lets you test one mechanic at a time. A simple spawner plus pathfinding NPC is enough for a first playable prototype.

TL;DR

Build the game as a locust swarm survival prototype: spawn locust NPCs, make them chase players with PathfindingService, and add wave-based difficulty. The cleanest Roblox setup is model in ReplicatedStorage, spawn part in the world, and a server script that clones enemies and controls movement.
