:) yo arrow keys to drive This is Super Scratch Kart Engine(no pun intended) Everyone's here! If this doesn't load, click copy link, copy the project link from there, not from the top bar, and open the link. It's an odd bug but its fixed in 1.2. 1.3 is at https://scratch.mit.edu/projects/396332174/
How to Add Drivers: Create a new costume in the character icons sprite. Add our character icon to the costume, and name it after your character. Now in the 'Player' sprite add a costume for your player with exactly the same name. Actually very simple. How to Add Places: Duplicate one of the (track name) Icon sprites. Change the sprite name, and go into the code. Look for the 'set variable Track: to ( )' block, and enter the course name there. Remember the exact typing or copy it. Now create a new costume in the 'Road' sprite, put your course there, and name it with your course name, exactly the same way as you did in the variable. Simpler than it sounds! To add music, just put your sound file into the road sprite, and name it the same thing as the costume you want it to play for.
