Key Press Event for I-key Key:
set variable invincible to true

Key Press Event for Q-key Key:

  image_blend = random(round(999999));
}

Key Press Event for R-key Key:

with(all)

  image_angle += 1;
}

Key Press Event for T-key Key:

Key Press Event for W-key Key:
execute code:

if (instance_number(point) > 1)
{
  Carla = random(point.id+1);
  x = (Carla).x;
  y = (Carla).y;
}

I want variable Carla to equal to a random point.id
and then for Explorer to go to the x and y position of whatever variable Carla is equal to.



Here is the error

___________________________________________
ERROR in
action number 1
of Key Press Event for W-key Key
for object explorer:

Error in code at line 4:
     x = (Carla).x;

at position 16: Unknown variable x

I Jason am using Game Maker 7.0 Pro Edition which I had for a super long time.

You'll want to replace that Carla line with:

Carla = instance_find(point.object_index, irandom(instance_number(point.object_index)));
