Starforge: make anything you can picture.

What Starforge is for

Starforge is for making things to put in your world: furniture, vehicles, statues, houses, ships, and anything else you can picture. It works with pictures, not numbers. You choose shapes and ready-made kits, paint them with a tap, and turn, flip, size, copy and mirror whatever is selected. Every number is still there if you want it, behind the Advanced switch.

Opening it and starting a design

Open Starforge from the main menu, or from the pause menu's Starforge button in a world. It opens on what to make: carry on with your last design, start a fresh one of a size you choose, or open one of your own. Every design starts from scratch.

The grid

Everything in Starforge is seen and made on the game's own grid, which is a sixteenth of a block. That is why a Starforge model fits in with the blocks around it. What you see on the screen is what the world draws.

Adding things

The drawers hold what you can add:

• Shapes: cube, soft cube, ball, egg, cylinder, cone, pyramid, ramp, dome, half round, hexagon, roof (a triangle lying down), ring, arch, bar, and pipe.
• Kits: ready-made parts that know what they are. A window cuts its own opening, and a lamp has its bulb. Others include a porthole, an arched door, table legs, a table lamp, eyes, a screen, a big button, a handle and a drawer front.
• Letters: lettering and symbols, in the game's fonts, for signs.
• Blocks: the game's own blocks, to build with, dig and spray.
• Game parts: the game's own ready-made parts.

Anything you drag sits on whatever it is over.

Editing

• Select one piece or several, then use the big buttons to turn, tip, flip, size, copy, twin (mirror) or make hollow.
• Hollow cuts a space out of what came before, so a box can become a room.
• Paint is one tap: pick a colour, a look, glowing or glass. The Paint tab holds the groups of paints.
• Brush touches up single blocks, voxel by voxel, when a shape is not enough.
• Undo and redo let you try things freely.

Starforge works with a mouse, with touch, and with a controller.

Checks while you build

Starforge weighs every change as you make it, and refuses one that would go over the limits. You will see a sentence saying why, such as a design having too many parts. The main limits are:

Rule	Limit
Parts in one design	400
Paints in one design	64
Pieces that must stay joined	One piece: nothing may float

The weight is worked out on what the world actually draws of your model, so a design that is light to look at but heavy to draw is still refused. Starforge also tidies a design as it goes: parts that draw nothing are removed, and paints that are the same become one. Each tidy step is checked, so a tidy never changes how the design looks.

Uploading

When a design is finished, press Upload. Starforge runs a final check, with a word on each rule, and then asks two things:

• Who sees it: private (only you), or public, where other players can find it in the Store.

If the check fails, the words say what to put right, and you can upload again when it passes. Once it is uploaded, your design is listed under your own name in the Store's Players section, if you made it public.

Using what you make

Items from the Store, and designs you have made, are kept in your Owned items. From there the Tools tab of the inventory can make one from what it is built of. See Inventory and belt for the Owned items button.
