so i was thinking of make a clone to minecraft so i made a block and drew a grass texture. when i placed the tex on the block it was like up right for one side but was rotated for other sites, what should i do?
You are using a standard Unity cube, which will display textures in the way that you describe. You need to use a cube from a 3D package such as Blender with the cube unwrapped it a way that displays your texture in the way that you desire.
I’ve made this quickly for you to see how(it is only rough!) :
