Little help?

Pedigree's method would be a good way to do it. You could actually make it so you could place as many dumbbells in the room as needed.

Here's what I would do:

• First, I would create a "bar" object. This is the object that you'd actually place in the room. It wouldn't have a collision event with the player.
  
• I would also create a "weight" object. This is the object that would actually hurt the player, so you'd need to put something in the relevant collision events.
  
• In the bar object's Create event, you'd create two weights. (This is the GM 8 syntax, but GM Studio 2's is pretty similar):

Code:

leftWeight = instance_create(x-32, y, obj_weight);
rightWeight = instance_create(x+32, y, obj_weight);

In the bar's Step event, you'd make sure that the leftWeight and rightWeight instances move at the same speed as the main object.

Does this make sense?

Course clear! You got a card.
