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:



                                                                                    Game Development in Sprite Lab  143
