Ok I thought, instead of complaining about this new block creator I might as well do something to fight it. I have decided to make a list of techniques I use when I create blocks.
1) Take advantage of the undo button. The undo button can save you a lot of time and is a whole lot easier than going back and trying to fix the block yourself.
2) Draw pixel by pixel. Set your brush size to one and zoom all the way in. If you want most of your block to be one color, before you start, make the entire block one color. Drawing one pixel at a time is a way to easily add detail.
3) Use the alpha option. This can tint your blocks to make them look better, or when you're erasing, you can make your blocks appear ghost-like.
4) Blocks don't have to be complex to look good. My blocks are all really simple, but I can still make them look good.
5) Shade and fade. Shading and fading are great ways to add effects to your blocks. Use dark colors for a shade and light colors for a fade.
6) Add onto your existing blocks. This is really helpful for me. I can just take my old blocks and edit them to make new blocks.
7) Along with shading and fading, use different shades of the same colors to do shading and fading.
8) Use the shift button. If you click then press and hold the shift button, you can make straight lines. If you need to make diagonal lines, click in a spot, then move your mouse to another spot and press and hold shift, then click.
9) As if it wasn't obvious enough, use all these techniques together.
10) DO NOT USE THE NEW BLOCK CREATOR PROGRAM!!!
I am hoping this will help at least a few people with making blocks. If you are already good at making blocks, you don't need this. I would also appreciate it if you would add some of your own block making techniques to help fight against this new program.
