3D games

A 3D game is built from a library of ready-made 3D models: people who walk, run and fight, cars, spaceships, buildings, trees, weapons and props, all free to use in what you publish. Setherion picks the ones your game needs, places them and lights the scene, with physics where the game needs things to fall, collide and bounce.

Change the models

Open Game art with the button over the preview. On a 3D game it lists every model the game uses, with its picture, in tabs by kind: Characters, Vehicles, Weapons, Pickups, Scenery and Level pieces.

1. Press Change model on one. The library opens with the models that suit it first, and a search box.
2. Pick a model and press Use this model. It is free, and the game shows it at once.
3. Not what you wanted? Undo is in the note at the top of the panel.

A model only replaces one that can do what the game asks of it. If the fighter in your game punches, a model with no punch says Has no Punch, which the game plays and cannot be picked.

• Missing from the library, at the top, is a model the game asks for that does not exist, so the scene shows nothing in its place. Pick a model puts a real one there.
• Changed through the chat is a model whose address the game builds from parts. Pick its replacement and Put in chat writes the request in the chat box for you to check and send.
• Add a model brings a new one into the game. Pick it, say where it goes, for example "a tree at each corner of the track", and Put in chat writes the request.

You can also start from the scene: select an object with Edit on, and the Model row in the panel beside the preview has Change, which opens Game art on that model.

A 3D game has Sounds, Settings and Scores in Game art too. See Game art.

Change the scene yourself

Press Edit above the preview on a 3D game and the game holds still. Click anything in the scene to select it, and a panel opens beside the preview.

The top of the panel says what you selected, as a path you can climb: Fighter › group › model is the fighter, the body inside it and its 3D model. Click a step to select that part instead. Under it are the file and the line of the game's code the object comes from. ×2 means that line draws two objects, here both fighters, and a change applies to both.

• Move it by dragging the arrows on it, one per direction, or set its Position.
• Turn it a quarter or a half turn with the buttons, or set its Rotation.
• Make it bigger or smaller with − and +, or set its Size. The sides stay in proportion, or the chain button lets you change each one on its own.
• Colour and glow, for the parts that have them.
• Animations, for a model that moves: play each one here to see it. Use writes the request in the chat, for you to say when the game should play it and send.
• Ask AI to change this one object, when what you want is not on the panel.

Every number can be typed, or changed by dragging its X, Y or Z. Hold Shift for fine steps.

The most used of them also float in a dark bar just above what you selected, so you can turn it, resize it, colour it or ask AI without leaving the scene.

When the game itself places and moves something as it plays, like a fighter during a round, its position and turn show a lock. Ask AI to change how the game moves it, or select a part inside it to place that part.

Press Save under the preview to write the changes into the game's code. It counts them as you go, Save (2) after two. Undo and Redo are at the foot of the panel, and Reset puts an object back the way the code had it.

Look around

Edit has a camera of its own, so you can look at the scene from any side without moving the player's. Drag to look around, drag with the right button or with Shift to slide, and use the wheel to come closer. Focus, a double-click on an object, or F frames what you selected. Game view returns to what the player sees. On a phone, one finger turns the view and two slide and zoom.
