Lesson 3 of 7
Game Mechanics
Master the rules, physics, and systems that dictate how players interact with the game world.
Learn it
Mechanics are the rules and actions that define what you can actually do in a game. Jumping, running, firing lasers, and gathering coins are all examples of mechanics.
When you combine simple mechanics, magical things happen. For example, jumping onto a bouncy mushroom to reach a high cliff combines jumping with world physics.
Good mechanics feel responsive. When you press a key, your character should react without delay so that moving around feels fun and natural.
Key terms
- Game Mechanic
- A specific rule or system that dictates how a player interacts with the game.
- Emergent Gameplay
- Complex situations that arise naturally from the interaction of simple mechanics.
- Velocity
- The speed and direction of an object moving through the game space.
- Cooldown
- A mandatory delay before an action or ability can be used again.
Tuning Platformer Physics
Discover how changing variable values drastically changes how a game feels.
- 1Adjust Gravity: Increase gravity to create a heavy, snappy fall, or lower it for a floaty space effect.
- 2Set Jump Impulse: Configure the initial upward velocity applied when the jump button is pressed.
- 3Apply Friction: Add horizontal deceleration so characters stop cleanly instead of sliding on ice.
- 4Add a Cooldown: Limit weapon firing rates to prevent players from overwhelming the screen with projectiles.
Simple Jump Physics Logic
python# Simulating vertical movement under gravity
gravity = 9.8
vy = 0
def press_jump():
global vy
vy = -20 # Impulse upward
def update_physics():
global vy
vy += gravity * 0.1 # Pull downward over time
print('Current vertical velocity:', round(vy, 2))
press_jump()
update_physics()Pressing jump sets a negative vertical velocity (upward), while gravity steadily increases velocity downward each tick.

Try it
Arrange the steps of a shooting mechanic in the correct chronological order.
- 1System checks if the weapon cooldown has expired
- 2Projectile velocity is set forward
- 3New projectile sprite spawns at player coordinates
- 4Cooldown timer resets to block rapid firing
- 5Player presses the fire button
