Hi,

I'm trying to let an object following a path with an action.
I tryed using the patrol_path() action example.
Problem I'm having is it dosn't recognize _FORCE and _MOVEMODE.
What is the best solution for this when I'm programming in a .c file?
Should I include some header?

Thanks in advance,

// move along a path loop

result = path_scan(me,my.x,my.pan,vector(360,180,1000));
if (result == 0) { return; } // no path found

// find first waypoint
var node = 1; // start at first node
path_nodepos(my,node,my._TARGET_X);

while (my._MOVEMODE)
{
// find direction
result = vec_to_angle(angle,vec_diff(temp,my._TARGET_X,my.x));

// near target? Find next waypoint of the path
if (result < 25) {
node = path_nextnode(my,node,1);
path_nodepos(my,node,my._TARGET_X);
}

// turn and walk towards target
actor_turnto(angle.PAN);
actor_moveahead(MY._FORCE);
wait(1);
}
}

#define skill20 _FORCE
#define skill21 _MOVEMODE

Thanks.... that fixed several bugs

next bugs are a bit harder:

#define skill22 _TARGET_X

vec_to_angle(ang,vec_diff(temp,my._TARGET_X,my.x));

i don't understand.
why do you need to #define the skill20-22 things?

it's just for giving names to skills, makes the code easire to read/write.

and
comments like
//uses:

makes skills show up in the behaviour panel of wed.

}
}

The code does run but as soon as the game starts he says: Error (E1513) crash in patrol_path().

The code is pretty basic and I can't find anything wrong with.
Anyone able to help me?
Thanks in advance!
