Minetest mod: boost_cart
=======================
Based on the mod "carts" by PilzAdam
Minetest mod: carts for MFF
===========================
Based on boost_cart and modified to fully *replace* carts (@Coethium)
- desactivate mesecons
- power_rail: accelerate, max_speed set in init.lua
- brake_rail: deccelerate, min_speed set in init.lua (so the cart doesn't stop and runs at very low speed)
- default:rail / rail_cooper : no friction, keep the current speed
- no collision (avoid the "walled_in" bug)
Boost_cart
==========
Based on (and fully compatible with) the mod "carts" by PilzAdam
Target: Run smoothly and do not use too much CPU
