Hello, I started making a Mod that ads a Ladder for every MC Block. I get the testblock I added to work like a Ladder(Hitbox, Climbing, Placement) and get the texture for the Item to work. BUT I don't know how i get the placed Blocktexture correct so I want to ask if somebody can help me. I use the vanilla ladder texture for testing and i copied the content af the ladder class into the class of my block. I tried to copy the content of the minecraft texturebased files too but it don't works. ?
