Maybe you can add the which we can put on the border for safety (i added the picture). Its not hard thing but i can help the for modelling something. i wanna improve this game. i wanna wok with you survivors!
I think you could make a similar wall out of corrugated metal plates and poles. Each plate block would be 1,000 hit points. You won't have that exact texture available.
There are some bandit blocks that are bigger than 1x1 that (IIRC) look similar. I don't recall how durable they are. Given that one of those blocks can be 2x3x1 with only one pool of hit points, I doubt it will be as durable as using the plate blocks.
Ah, I see. They've been up against a texture limit for the paintable textures, but when it comes to blocks they can put textures on them. You might look for those bandit blocks. I don't recall their block names, but I could look them up for you. I doubt there's a recipe to make them in game, but that's an easy mod to make.
