Go to your game's files and find a folder called 'js'.



Now locate a file called 'rpg_core.js' and open it with a text editor.

Press Ctrl + F and search '38', it'll take you to the key mapper lines.



Every key on your keyboard is assigned to a value, if you want to know them all just search for 'Javascript Character Codes' or 'Javascript Key Codes'.

Here's all of them, if you're curious:



If you want your basic movement keys to be WASD, change them to these:

• W is 87
  
• A is 65
  
• S is 83
  
• D is 68

Just like in this picture:

If you want to make your character move with the WASD keys, you'll notice that the W value is already being used for 'pagedown' by default.

You can change 'pagedown' to another value or just simply remove it.



In my case I just removed it.

You can make your character move with both WASD and the arrow keys if you want, you just need to have them both on 'rpg_core.js' just like in this picture below:



And that's it, thanks for reading!
