Carts (formerly boost_cart)
|
||||
==========================
|
||||
|
||||
Cleaned up for merge based almost entirely on SmallJoker's boost_cart
|
||||
mod (github.com/smalljoker/boost_cart).
|
||||
|
||||
That in turn was based on (and fully compatible with) the mod "carts"
|
||||
by PilzAdam
|
||||
|
||||
The model was redone, but based on github.com/stujones11/railcart, CC-0
|
||||
|
||||
Cart Textures are based on original work from PixelBOX (WTFPL).
|
||||
|
||||
|
||||
Features
|
||||
----------
|
||||
- A fast cart for your railway or roller coaster (up to 7 m/s!)
|
||||
- Boost and brake rails
|
||||
- Rail junction switching with the 'right-left' walking keys
|
||||
- Handbrake with the 'back' key
|
||||
|
||||
|
||||
Additions by TenPlus1
|
||||
-----------------------
|
||||
- Mesecon detector rail added
|
||||
- 10 second cart drop when player or item not inside
|
||||
- Alias' set to replace older boost_cart mod
