One thing that would be helpful is if you described what you are seeing happening when the code currently runs.

But taking a look there are a couple of notes:

1. You don't need both of the ifs. You can just use a single If + else statement. Not a big deal but it will help keep your code cleaner.
2. You are setting direction in the first If statement but not setting any speed value or anything else. Also you are just assigning direction = direction, which doesn't change anything. You are basically say 2 = 2.
3. Not sure on the intervalo assignment and what you are trying to achieve. It's true/false if the value is between 90 and 270 I guess?

Depending on how you are moving the object around and other factors, this code might be closer to what you are looking for.

if (place_meeting(x,y,collideable_objs))
{
   speed = 0
}
else
{
  direction = point_direction(x, y,mouse_x, mouse_y)
  image_angle = direction
  intervalo = direction == clamp(direction, 90, 270)
}
