PICO-8 Wiki
run [str]

( [str] )
Runs the current cartridge from the start of the program.
A "breadcrumb" string, as if passed by a calling cartridge.

When run as a system command at the PICO-8 prompt, this starts the program. If the program was running previously, run resets the game state and starts from the beginning.

When run() is called as a function, the runtime environment resets and the program executes from the beginning.

A string may be passed as a "breadcrumb" that the cartridge can find in stat(6). Breadcrumbs are usually used when one cartridge loads another and wishes to tell the other where it came from. This is a way to simulate that, or to retain the existing breadcrumb if the cartridge chooses to re-run itself.


At the PICO-8 prompt:

> run

> run this is my breadcrumb

> run "this is my breadcrumb"

Note that quotes are optional and both of the latter examples produce the same result.

In source code:

-- reset the program

-- reset the program with a breadcrumb
run("this is my breadcrumb")

-- reset the program and preserve the current breadcrumb
