Step 2 Define their movement patterns to challenge the player.
Use the set speed block to make cars move at a constant speed.
This makes the enemy car move linearly.
DESIGNING LOGIC FOR GAMEPLAY MECHANICS
Creating a fun and interactive game requires well-structured logic for movement, scoring,
collisions, and game progression. Here’s how you can design gameplay mechanics for
your car racing game in Code.org’s Sprite Lab.
IMPLEMENTING EVENT HANDLING
Event handling enables the game to respond to player inputs.
It is used to detect player actions (like key presses) and trigger
responses in the game. In your car racing game, you can use
event handling to move the car left and right when the player
presses the arrow keys.
Example:
Use when up arrow pressed à Change y by -5
Use when left arrow pressed à Change x by -5
Use when right arrow pressed à Change x by 5
ADDING COLLISION DETECTION
Collision detection is essential to check if the player’s car crashes into an obstacle. This
helps trigger events like game over or score increase. This can be implemented using
conditional statements:
