Slider rails
There are now some new parts in the game, and a new attachment type. Slider rails can attach to blocks either with a rigid or with a slider attachment (you can cycle between these). The slider attachment allows relative linear motion between two parts in one direction only. This allows you to create sliding platforms, lifts, extending crane booms, and all sorts of other things!
Construction mechanic
I have also made some improvements to the construction game mechanic to make things work a bit better:-
- The construction you have currently selected no longer collides with other constructions. This prevents you from accidentally knocking other stuff around due to physics collisions with the selected construction.
- After cloning a construction, it becomes currently selected. It used to be that the construction would collide with its clone, causing stuff to fly around uncontrollably; this no longer happens.
- You can now only detach parts from frozen constructions. Given that you can only attach parts to frozen constructions, I think this behaviour is more consistent.
