Playing

• player controls turns on W A S D, space and the mouse (click the stage; Esc releases).
• The target points at the block in the center: use is a block targeted?, crack, break and place in front of the target.
• show hotbar / hearts / crosshair / hand builds the game screen; 1 to 9 and the wheel choose the item.
• Sprites get a 3D body (zombie, pig, sheep…) and move with walk towards the player, run away and wander. Sprites without a 3D body appear on top, like a HUD.

See the example Craft 3D: mine and build.

New 3D examples

• 3D coin hunt (easy): the simplest one to start with. Open
• 3D parkour with characters (medium): platforms over lava, checkpoints and animated 3D characters. Open
• 3D Dungeon: retro shooter (hard): an original first-person shooter in 90s style, with a brick maze, 3D robots and aliens, ammo and health kits. Open

Several 3D backdrops (one world per backdrop)

• Each backdrop of the stage can have its own 3D world, so a game can have several 3D levels.
• In the Backdrops tab (with the Stage selected), the "3D World" button creates a 3D backdrop; 3D backdrops get the 3D badge and an "Edit in the 3D world editor" button.
• Switching backdrop (the "switch backdrop to ..." block) loads that backdrop's 3D world. A 2D backdrop hides the 3D one.

A menu button that starts the game (no flag)

• Clicking a sprite that has "when this sprite clicked" already starts the game — no green flag needed. Make a Menu backdrop (2D) with a "Play" button that uses "switch backdrop to" to go to the 3D level.

Macro editor (generate scenery by repetition)

• In the 3D world editor, the "Macros (blocks)" tab is a block editor to build scenery with repetition: "fill", "filled/hollow box", "sphere", "column", "repeat N times", "for i from … to …", values and "world size". Click "Run macro" to generate (undoable).

3D characters from a file (.glb) in the game

• A sprite with a 3D character (modelo3d, from the generator OR a .glb file) shows in 3D in the world. In "player appearance" and the 3D World menus it is marked with (3D).
• See the "3D Hero Adventure" example (menu + 3D backdrop + file character). Open
