At the end of this tutorial series we'll have a level that looks like this one here:

But not until later will it be actually playable!

Right down here I've made a little tutorial on how to make the block properties or you can watch the more in depth video here:

If you've watched that you really don't need this but here it is anyway:

The main goal of the block properties editor is to create tiles or "blocks"for use within the main map geometry. To start select block prop 1. I wouldn't use block prop 0, since usually thats used as an "air" block because maps are automatically cleared with block type 0 when making a new map. When making a block you can edit multiple things.

                   Transparency (0 is opaque, 7 is fully transparent).

                    Damage Types:

                                        None: Will never damage the player

                                         Lava: Acts like water giving the player inifinte jumps, and making the player move more slow.

                                         Spikes: Just damages the player.

                     Damage: how many hit points this block deals to the player per frame.

                     Solid: Whether or not the block can be stood on by players and enemies.

                     Collision Type:

                                         Hitbox: The solid part of the block is defined by a box that can be changed when you enter into the collision data sub-menu.

                                          Heightmap: The solid parts of the block snap players and entities up above that part so it looks like they are walking on it. The solid parts of the block are made up of a line for every pixel column of the block so 32.

                       Animation speed: The number of frames that each frame in the animation has.

                       Number of frames: The number of frames in the animation

                        Find Bitmap: You may search through the graphics of the game for a block in-game.

When you're done MAKE SURE TO SAVE IT AS *.CNMB!!!
