Every single var is said to be "Undefined". But I've defined them all right here! What is going on and how do I fix it?

usr refers to /mob not /mob/trainer. Define variables under /mob or use :

Or don't use :, like, ever. Proper type casting is your friend. Just use var/mob/trainer/T = usr, then reference T instead of usr.

There is a time and place for it, but that time never comes for beginners. Defining the vars under /mob is a good option; type-casting works too. However in any case the code won't operate because he used if(src==/mob/trainer) which is always false--since src is a mob and not a type path--whereas he should have used if(istype(src,/mob/trainer)) instead. | |
okay, i removed /mob/trainer and just used mob, but after compiling, the src. variables are STILL undefined.
I obviously defined them, does anyone know what's wrong? | |
The aforementioned typecasting is still necessary in the case of src because src could be any type of atom, not just /mob. The compiler doesn't take the fact that it can't possibly NOT be a mob due to the conditions of getting there into account, so you still have to specifically tell it what src is.

Actually, src will always be type-casted to the same type as the source object. I'm not sure what the OP did, but I'm guessing he just changed if(src==/mob/trainer) to if(src==/mob)... @OP: If you change your code, and your problem isn't solved, it's helpful to show us the updated code so we can see what you tried. Also, your arguments for walk_to() are incorrect. It's not a mob process, it's a global one, so you need to pass it the atom/movable you actually want to move. See the linked-to reference entry for the arguments. | |
