Challenge Threadᆦ ᆦ ᆦ

[Apjjm]

It's not quite as difficult as the previous challenge - i couldn't really think of a problem like that so instead opted for a more gameplay oriented challenge:

Counterweight puzzle
A room contains two bridges. One of the bridges must be lifted by weighing down another enough to permit the player to cross the bridge to the edit door. Barrels and the player both act as weights.

Specification

Spoiler below!

1. A counterweight puzzle must be designed (as bridge_1 moves down, bridge_2 moves up by the same amount). The movement of the bridges must be affected by the weight of the objects on the bridges (E.g. having one barrel on each bridge, then adding a second one to a bridge should move the second bridge down).
2. Barrels or the player may be placed on a bridge to weight it down
3. At least 4 barrels must be placed on the bridge_1 before the puzzle can be completed
4. Bridges must move up and down according to the weight difference.
5. The player must "weigh" more than a barrel.
6. It should not be possible to weight down a bridge so much that either clips through walls/floor.
   

Additional notes

Spoiler below!

• You are free to change the bridge entity files
• You are free to add or remove entities/areas/etc from the map
• You may want to download this entity file (it may help depending on your approach).
• Barrels should ideally be touching the bridge entities if they acting as weights.
