...has anyone determined the most efficent way of achieving content launching for causing terminal perforations on invaders...?
This -
"New stuff
Minecarts can be used to haul things around on carved/constructed tracks/bridges ('h'auling to set up routes)
Dwarves can be set to guide, push off, or ride carts that are ready to move to the next stop
Track stops used to slow/stop cart and/or dump the contents on vehicle entry, can be disengaged with lever/plate
Pressure plates can be triggered by carts
Rollers can be used to push cart along when powered
Minecarts limited to one per tile in general, various collisions can occur
Wheelbarrows can be linked to stockpiles in order to move heavy objects (it'll auto-request one for stone stockpiles)
Falling objects can collide with critters
Camera can be attached to unit or item, can be linked to hotkeys from the unit/item screens"
Nothing about content physics.
I think there is only way to "launch" minecart content is to assign it to stop & unload it. But thing is there is no way to launch this content how it Girlinhat did. It was his joke. The minecart is unload all content at directed tile & move out without stop. This content doesn't have kinetic power of minecart when it unloaded.
There is no other way to "launch" content.
