Speed Rails... Fix?

Anomaloavis

This is nothing major, I just modified the super fast minecart commands I mentioned earlier to work with powered rails rather than redstone and made it slope-tolerant.

It still only accelerates in the direction the rider looks in though. I tried to make it direction-constant, but after 4 hours of experimentation, I've decided that there is no way currently in the game to detect the movement of minecarts. Unless you use detector rails before every tunnel, of course, but that would kill Andy. 

Simply put these in four separate repeating, always on command blocks.

/execute @a[rym=135,ry=-135] ~ ~ ~ detect ~ ~1 ~-4 minecraft:golden_rail -1 /tp @e[type=MinecartRideable,r=1] ~ ~ ~-3

/execute @a[rym=-134,ry=-45] ~ ~ ~ detect ~4 ~1 ~ minecraft:golden_rail -1 /tp @e[type=MinecartRideable,r=1] ~3 ~ ~

/execute @a[rym=-44,ry=45] ~ ~ ~ detect ~ ~1 ~4 minecraft:golden_rail -1 /tp @e[type=MinecartRideable,r=1] ~ ~ ~3

/execute @a[rym=46,ry=134] ~ ~ ~ detect ~-4 ~1 ~ minecraft:golden_rail -1 /tp @e[type=MinecartRideable,r=1] ~-3 ~ ~
