FATAL ERROR in

for object obj_enemy1B:

I can't find where is this error.

Basically it means that
Code: 
VelocidadHorizontal
is undefined at that point in the Step Event.
Try declaring with a starting / default value in the Create Event.

Click to expand...

my create event is this

///variables
Camina = false;
Ataca = false;
Dir = -1;
MoveSpeed = 5;
Estado = 0;
VelocidadHorizontal = 0;
VelocidadVertical = 0;
Grav = 0.2;

That looks OK.
What's the full code in the Step Event?

I don't see the problem either, so I'm thinking it's probably not your code. Try clicking the 'clean' icon (next to the 'play' icon... it looks like a broom or dustpan). Or if that doesn't work, restart GameMaker or reboot your computer. Other than that, I have no idea.

I think GM is searching for an object named "VelocidadHorizontal" or an object that contains the variable "VelocidadHorizontal" or something.

I am not certain that brackets can be opened after "repeat". Maybe it's that.
Code: 
 repeat (abs(VelocidadHorizontal))
            {
and you should clean the lines a little bit
Code: 
if ((place_meeting(x + sign(VelocidadHorizontal), y, obj_roca))
    && (place_meeting(x + sign(VelocidadHorizontal), y -1, obj_roca))
    && !(place_meeting(x + sign(VelocidadHorizontal), y -2, obj_roca)))
    {y -= 2;}
And a detail
Code: 
if Estado = 0
 if (Estado == 0)
And easy on the computer reboot; it was never required for me.

Now that I'm trying to understand your code, why are you checking for a collision above at "y -1" and then if there's not at "y -2"....

Code: 
place_meeting(x + sign(VelocidadHorizontal),y, obj_roca) --- checks for a collision in front;
place_meeting(x+ sign(VelocidadHorizontal),y -1, obj_roca) --- checks for a collision in front and above;
!place_meeting(x+ sign(VelocidadHorizontal),y -2, obj_roca) --- checks if there's *none* in front and above;
Everything, all at once; confusing.

Thanks
those checks what they seek is that the enemy object can walk the ramps and slopes in addition to attacking the player depending on the distance in which the player

at the beginning it worked very well until this error appeared that has paralyzed me the project, it is frustrating I have done everything to erase that object and program it again, I am really baffled.

if the object is necessary, you don't have to delete it, just edit its code.
If an event makes it disapear when another object is looking for it, an error can return.
Code: 
if (instance_exists(your_object))
{}
can prevent conflicts.

But if it's bad coding, and you're not certain where the problem is, put everything in between "/* your code */"; select a part in it, place it outside the "/* */", test your code and work your code piece by piece.

Code: 
 repeat (abs(VelocidadHorizontal))
            {
try to remove the brackets { } of your "repeat" as a test and run your game; you'll see if it's related.

Code: 
place_meeting(x + sign(VelocidadHorizontal),y, obj_roca) --- checks for a collision in front;
place_meeting(x+ sign(VelocidadHorizontal),y -1, obj_roca) --- checks for a collision in front and above;
!place_meeting(x+ sign(VelocidadHorizontal),y -2, obj_roca) --- checks if there's *none* in front and above;
Here, you are saying : if my object collides with "roca" (in front and on top), do something.... but only if my
object doesn't collide with "roca" one pixel higher than what I was checking. It's like saying: if my head hits the wall and the ceiling, but doesn't touch anything higher than that, I can walk. You could just write:
Code: 
if ((place_meeting(x, y, obj)) && !(place_meeting(x, y -1, obj)))
{y -= 2;}

Do yourself a favor and cleanup the code as Neonbits suggested. You have to be able to read the code yourself before trying to debug anything. In the first group of ifs, you're enclosing only the first condition in parentheses, the others are not enclosed and the whole thing isn't enclosed either. In the second group of ifs, you follow a different scheme.
Other than that I can't spot anything obvious. I'm sure the more experienced users will be able to help you out. But first please help them help you by doing some housekeeping.
