I have been trying to mess with one of my teammates who hates putting Scotty (that is just what our team calls the vex iq Sammy) on our robot so I tried to add him to the brain with .draw functions. it just sends vex memory permission error 038015fc, I don’t know if there is just not enough storage in the brain to use the images or if it has a different problem, here is my code:

#include "vex.h"

Doesn’t crash for me, but that code has plenty of other problems.
At what stage does it throw the memory error ?
Is the brain firmware up to data ?

Don’t worry about my driver control, I was just waiting to make that for a time I can test it

it shows on the error on the brain screen instead of printing to it

Are you using VEXcode or (remember obsolete) VEXcode Pro ?
If pro, it it probably these lines.

int fb = Controller1.Axis3.position();
int lr = Controller1.Axis4.position();
int turn = Controller1.Axis1.position();

which make no sense anyway, if the plan was to shortcut using the controller axis, it doesn’t work that way.

also this line

Motor1 = true;

is useless if Motor1 is an instance of a motor.

edit: and the explanation
Pro creates the motors etc. in a file called robot-config.cpp, this code that generates the motors, and controller, will run after the global code in main.cpp, that means that when you tried to do

int lr = Controller1.Axis4.position();

The Controller1 instance did not exist, hence the crash.

you need to assign controller axis to lr etc. at the top of you while loop in usercontrol.

ok, I trimmed the unnecessary code other than the other variables and it prints now, I got the coordinates wrong so it looks bad but I can fix that, thanks
