⚔️ Need help with enemy damage system

Hey everyone! I’m working on a combat game and I need help with two main things:

  • How to make enemies take damage when attacked
  • How to make enemies deal damage to the player

I’m pretty new to combat mechanics and would really appreciate some guidance! 😊

Great question @TheDuke_Gamer! Combat systems are really fun to build. Here’s a comprehensive guide to help you create both enemy and player damage systems:

🏥 Step 1: Create Health Variables

First, create health variables for both player and enemies:

    when flag clicked
set [Player Health v] to [100]
set [Enemy Health v] to [50]

⚔️ Step 2: Enemy Takes Damage System

For enemies to take damage from player attacks:

    // In Enemy sprite
when flag clicked
forever
if <touching [Player v]?> then
if <(costume name) of [Player v] = [attacking]> then
change [Enemy Health v] by [-10]
play sound [enemy hurt v]
set [ghost v] effect to [50]
wait [0.2] seconds
set [ghost v] effect to [0]
if <(Enemy Health) < [1]> then
broadcast [enemy defeated v]
hide
stop [this script v]
end
end
end
// Check for projectile damage
if <touching [Bullet v]?> then
change [Enemy Health v] by [-15]
play sound [enemy hurt v]
broadcast [bullet hit v]
if <(Enemy Health) < [1]> then
broadcast [enemy defeated v]
hide
stop [this script v]
end
end
end

💔 Step 3: Player Takes Damage System

For the player to take damage from enemies:

    // In Player sprite
when flag clicked
forever
if <touching [Enemy v]?> then
if <(costume name) of [Enemy v] = [attacking]> then
change [Player Health v] by [-20]
play sound [player hurt v]
set [ghost v] effect to [50]
wait [0.3] seconds
set [ghost v] effect to [0]
if <(Player Health) < [1]> then
broadcast [game over v]
stop [all v]
end
end
end
// Check for enemy projectiles
if <touching [Enemy Bullet v]?> then
change [Player Health v] by [-10]
play sound [player hurt v]
broadcast [enemy bullet hit v]
if <(Player Health) < [1]> then
broadcast [game over v]
stop [all v]
end
end
end

🎯 Step 4: Advanced Combat Features

Here are some cool additions to make your combat system even better:

Damage Immunity (Prevents spam damage):

    // Add this to prevent continuous damage
when flag clicked
set [damage immunity v] to [0]
forever
if <(damage immunity) > [0]> then
change [damage immunity v] by [-1]
end
end

// In damage detection
if <touching [Enemy v]?> then
if <(damage immunity) = [0]> then
change [Player Health v] by [-20]
set [damage immunity v] to [60] // 1 second at 60 FPS
play sound [player hurt v]
end
end

Health Bar Display:

    // Create a health bar sprite
when flag clicked
forever
set size to ((Player Health) / [100] * [100]) %
if <(Player Health) > [60]> then
set [color v] effect to [0] // Green
else
if <(Player Health) > [30]> then
set [color v] effect to [25] // Yellow
else
set [color v] effect to [0] // Red
set [brightness v] effect to [-50]
end
end
end

Critical Hit System:

    // Add random critical hits
define deal damage (base damage)
set [damage v] to (base damage)
if <(pick random [1] to [100]) < [15]> then // 15% crit chance
set [damage v] to ((damage) * [2])
say [CRITICAL HIT!] for [1] seconds
play sound [critical hit v]
end
change [Enemy Health v] by ((-1) * (damage))

Hope this helps you build an awesome combat system! Let me know if you need help with any specific part! 🎮

@CombatMaster_Pro This is exactly what I needed! Thank you so much! 🎉

The damage immunity system is really clever - I was wondering how to prevent spam damage. Going to implement this right away!

Great solution @CombatMaster_Pro! Here are a few additional tips for @TheDuke_Gamer:

  • Sound Effects: Different sounds for different damage types make combat feel more impactful
  • Visual Feedback: Screen shake, particle effects, or color changes help players understand what’s happening
  • Damage Numbers: Show floating damage numbers above enemies when they take damage
  • Status Effects: Consider adding poison, burn, or freeze effects for more complex gameplay

Keep experimenting and your combat system will feel amazing! 🎮
