Can anyone tell me how to detect which blocks are which and how placing block's would work.

I think what most people use is an array of the blocks...or a list that can be displayed in two dimensions.  This can be done using either letters or a little math.  Then, depending on your block size, wherever your player is, divide both the x and the y by the block dimensions and round it...you might also have to offset it by a number so that it gets the right placement for the blocks...hope that at least helps some...if not, let me know.

what about how to detect which blocks are which

The list. You create a list as the world generates (yours does right?) and use the grid snap thing to determine which list item to use to determine what block it is, and it's midnight time and whatnot

That doesn't make sense to me.

well, as a world is generated add the block yo a lis (air counts yo). Use the mouse coordinates on the grid to find which item youd be editing.

That doesn't make sense.

That doesn't make sense.

1. Use a variable list to label block IDs.
2. Use your imagination to cycle through blocks
3. Click on air (0 ID)
4. ???
5. Profit

You store the world as a long list of numbers.  Each blocktype is a different number.  For example, air might be 0, mud might be 1, stone might be 2.  When the mouse is clicked, you use a grid snap to determine which square it is touching.  Then, you use some math to locate the item in the list that corresponds to that location onscreen.  You check the value of that item to determine what the value of the block is.

Hope that helps.

EDIT:  I just remembered that I made a long post about something like this awhile ago.  Here's the link to the the post.

That doesn't make any sense to me at all.

@DonutCannon that doesn't make sense either.

I'll try to explain again.  You store the data for the world in a list.  Each item of the list stores a number that represents a block.  The value of each item is the type of the block.  You can imagine it this way: if the world grid was 15 x 20 blocks, you would label each block with a number, going from top left to bottom right.  That number would be the item number of the list that corresponded with the appropriate block on the screen. 

Code:

Numbers represent the location of each tile type in the LevelData list.  
For example, "127" means that item 127 of list LevelData would occupy the spot at the 9th column and 7th row.

EDIT: Here' s a project Hardmath123, applejack, and I made where the level is stored in a list.  All the physics/sensing is done with math, by checking the player's position and the values of the items in the list (no color/sprite "touching" blocks were used).  Hope that helps.  http://scratch.mit.edu/projects/amcerbu/2437350

Yeah.... I don't get that at all..........

What parts don't make sense to you?  That might help us explain.
