the include doesnt load if it isnt in the direction file
you can us path/ for that
and i had a lot of problems in the place it is on

exapmle

#include "Kamera.c"
#include "invgdf.c"//loads global vars,panels,entity,strings,enz.

now the camera doesnt know stuff out of invdfgfd.c

so i needs to be

#include "invgdf.c"
#include "Kamera.c"
