How To Make A Block?

How to make a block in modd.io? i cant make block.i can only make play can walk in it.I cant make block,can someone tell me how?

block,:V,i dont know what is this block

@Eletr0mega I think he means how to make a consumable block that the player can interact with like base builder 3.

Basebuilder,u consumable and make a wall?
Or consumable a item and make a object and u can move?

when consumable make a wall:
Make a consumable item(not important much)
Create a New script>put trigger>when unit uses item>Create script>if / else / then>Item Type Comparison>item type of >entity< = = item type of entity>(entity)>last used item>item type of ( last used item ) = = >item type of entity>Constant>(the consumable item)>then do:>create unit at position>create >unit type< for entity at position facing angle radians>(unit type)>wall(wall of u like create(the wall need kinematic not dynamic in default body types))>for entity=ai(need player(Computer (aleatory number) AI in global variables)>at position=entity position(position of ( last used item ))>facing angle=0 radians

when is object to move,when dynamic,not kinematic.

if u mean make a tileset u can use piskel and to set the block sizes click export and put 64x64 for best results

and if u wanna make a wall then just click walls on left middle side
