How can I remap keyboard controls from arrow keys to WASD for player movement in GameMaker?

Remapping Keyboard Controls in GameMaker from Arrow Keys to WASD

To configure player movement in GameMaker from the default arrow keys to the WASD keys, follow these steps to ensure smooth and responsive control mapping:

Step 1: Identifying Key Mappings

• Arrow Keys: Traditionally mapped for player movement. up, down, left, and right.
• WASD Keys: Substitute keys where W maps to up, A to left, S to down, and D to right.

Step 2: Implementing Code in GameMaker

Add the following code in your GameMaker project, typically within the object responsible for handling player movement.

Play, have fun, and win!

if (keyboard_check(ord('W')) or keyboard_check(vk_up)) {
    y -= speed;
}
if (keyboard_check(ord('S')) or keyboard_check(vk_down)) {
    y += speed;
}
if (keyboard_check(ord('A')) or keyboard_check(vk_left)) {
    x -= speed;
}
if (keyboard_check(ord('D')) or keyboard_check(vk_right)) {
    x += speed;
}

This script utilizes the keyboard_check function to listen for specific key inputs. ord('W') checks for the ‘W’ key, while vk_up is used for the up arrow. This dual check ensures that both WASD and arrow keys are recognized.

Step 3: Testing and Adjustments

• Run your game: Ensure both WASD and arrow keys move the player character as intended.
• Tweak speed: Adjust the speed variable to match your gameplay needs for a smooth experience.
• Debugging: Use GameMaker’s debug tools to verify key presses and movement in real-time.
