hey guys, looking for a way, already using collision lines, to detect collision lines from all possible points in the room and return the closest true point so you can then move there.

how exactly can i do that?

Perhaps I am inexperienced. But I do not know what you are asking. Could you please rephrase that?

instance_nearest()

cool, but in addition i want to calculate all possible collision lines on the room from every point, is there a way to do that?

If I understand correctly, this would be incredibly slow.
Something in the lines of:

dir=0;
len=128;
repeat(360) {
  _x = x+lengthdir_x(len,dir);
  _y = y+lengthdir_y(len,dir);
  collision_line(x,y,_x,_y
  dir++;
}

?

If you want pathfinding, look at mp_ functions

sorry, i don't understand this code or how to use it can you explain?

I'm having a hard time trying to understand what your question is. Could you please rephrase that in detail?

Judging from your "all possible collision lines on the room from every point" comment; if you want to get the distance from each instance, you need a simple with construction.

with (object) {
    ds_list_add(other.my_list, id, point_distance(other.x, other.y, x, y));
}

The above code will populate a list with instance ids at even indexes (n; 0, 2, 4, ...) and their respective distances from the caller of this code at odd indexes (n+1; 1, 3, 5, ...).
