Most optimum way to use ice on long corridors?

I've been working on a survival map for a while, and right yesterday got my ice farm.

So the fact is that I want to use this ice to move faster between portals in nether, but also at some places in overworld.

My corridors are 2*2, but I have to hold me to use everything as packed ice because it will take for ages for me to fill those corridors, even if I do it in 1 side of the 2 they have.

So how do I have to difference between packed ice and normal ice at nether and overworld? Do trap doors help when holding light away from ice blocks?

Solution 1:

Ice is usually not used for iceways as it melts, you should try other non-melting variants like blue or packed ice.

If you are in late game and still want to use ice(for looks?) you could have perpetually bouncing armor stands with frost walker along the ice to turn it into ice again and again(but this is not efficient) for the overworld. No easy solution for the nether though.

Maybe you should just find the variants if you do not want to keep the iceway pitch black. Find a biome here chunkbase.com/

As for the trapdoors, they are used for better jump sprinting in corridor, as they break your jump faster than only full blocks, whereas a half slab does not let you jump(I suppose thats why you mention trapdoors-from tutorials).

Good luck on your adventures in survival!
