It is possible to draw directly in Custom using the built in Graphics Editor, or you may find it easier to draw your art using other software and then importing graphics into the OHR. You can also skip drawing your own graphics by using ready-made graphics freely available from the Resources page.
You don't need to draw everything right away, you can swap out and add more as you go along, but you will need at least some images to represent map tiles and walkabouts to begin with.
Piece together tiles from a tileset to assemble maps, and later fill maps with walkabouts/NPCs.
Main Menu > Edit Graphics > Edit Tilesets
Each tile is 20*20 pixels and a tile set is a collection of 160 tiles, that you will later piece together like a mosaic to create your maps. Upto 16 tilesets can go into one map (see Using Map Layers).
The screen is divided up into 160 tiles. The first one (top left) is the tile that will fill every map by default. You will want this one to be grass, water, void, whatever your map will be full of before you edit it.

- Arrow keys move your cursor
- SPACEBAR places a pixel, fills a area, or starts/finishes a line or box
- Hold ALT + arrow keys to change your current drawing color
- period and comma also change drawing color
- ENTER or Right-Click matches the current drawing color with the pixel under the cursor

While in the tile browser you can copy tiles with CTRL+C and paste them opaquely with CTRL+V and transparently with CTRL+T.
Wall Tiles and Obstacles
The Hero will encounter many obstacles in their path, and none is more primary than the humble wall.
From the Tileset Menu, select Set Default Passability.
As you press SPACE you will place walls on the map. You can also set passable/impassible for each side of a tile individually, either with a left mouse click or hold Ctrl +Arrow-keys for the desired direction(s). A flashing box around the tile represents impassability.
One-Way walls can be made by pressing W over a tile first to convert it to One-Way, then specifying direction(s) for the walls, now indicated by arrows.
Walls can be further tweaked again in the Map Editor, so keep it simple at this stage.
Roaming NPCs will obey these Passability rules unless specified in the NPC Editor > Ignore Passmap: YES.
All the colors in your game are sourced from the master palette, limited to 256 colors.
Note that the OHRRPGCE defaults the top-left colour of a master palette to the transparency colour, which by default is black, but that this can be changed in the various editors submenus or by changing it permanently on the master palette. For Tilesets, this option is under View with background: color. Pick a color you wont use elsewhere, which is much easier to draw against and allows you to see when drawing with the color black.
To change master palette, from the main menu, select, Edit General Game Settings > Graphics > Master palettes..., then press right arrow key on <- Master Palette 0 ->. But the default is fine and there's no need to change the master palette just yet.
