try to use a pointer instead of a vector
VECTOR* path_nodepos = { x=0;y=0;z=0;}

When i use pointer instead of a vector , I have an other error :

can't initialize global structs in functions .
< VECTOR* path_nodepos = { x=0;y=0;z=0;}>

then you should do this:
VECTOR path_nodepos;
function set_path_nodepos()
{
vec_set(path_nodepos,vector(0,0,0));
}

Look at this :

line 136

cou can't name any variable like a function

i am send code for you with P.M .

You're not actually showing what's on line 136 in the image, though line 115 and 117 will cause a few problems.

You've also only declared VECTOR path_nodepos in set_path_node function and not in the patrol_path action where you're trying to call it, (from what is shown).

what is your Idea for solve this problem ?
