Part 1 — An empty project and a character that moves

This is the first of five parts. By the end of all five you will have a complete platformer — art, level, score, enemies, sound and a published link — built from an empty project without writing code.

By the end of this part you will have a character that runs and jumps.

Create the project

1. From the dashboard choose New project.
2. Pick Blank 2D. It has one scene, three layers and nothing else.
3. Name it My Platformer and create it.

The editor opens on an empty stage. The left panel has three sections — Scenes, Hierarchy and Assets. The right panel is the Inspector, which always shows whatever is selected.

Generate the art

A blank project has no assets. You do not need to draw or download anything — the editor can generate sprites from a handful of numbers.

1. In the Assets panel, press the ✨ button.
2. Leave Kind on Image.
3. Set Generator to character. A preview appears.
4. Name it hero.
5. In Options, try changing "palette" to "goblin" or "canary" and watch the preview update.
6. Press Add to project.

Now do it again for the ground:

1. Press ✨ again.
2. Generator roundedBar, name ground.
3. Set the options to { "width": 1280, "height": 48, "color": "#4ade80" }.
4. Press Add to project.

Put them in the scene

Double-click an asset tile to drop it into the middle of the stage, or drag the tile onto the canvas to place it where you want.

1. Double-click ground. It appears in the Hierarchy.
2. With it selected, set Y to 660 in the Inspector so it sits near the bottom.
3. Rename it to Ground — the field at the top of the Inspector.
4. Double-click hero. Set X to 200 and Y to 500.
5. Rename it to Player.

Give them physics

Nothing falls or collides until it has a body. Two kinds matter here:

1. Select Ground. In the Inspector find Physics and turn it on. Set Body to static.
2. Select Player. Turn physics on, set Body to dynamic, and tick Collide world bounds so it cannot leave the screen.

You also need gravity, which is a project setting rather than a per-entity one. Click empty canvas to deselect, and the Inspector shows the project. Under Physics, set gravity Y to 980.

Make it controllable

1. Select Player.
2. Scroll to Behaviours in the Inspector.
3. From the dropdown, choose platformerController.

The behaviour appears with its settings. Reasonable starting values:

speed          220     sideways movement
jumpVelocity   520     how hard the jump pushes
coyoteMs       90      grace after walking off an edge
jumpBufferMs   120     grace for pressing jump just before landing

Play it

Press Play in the top bar. Move with the arrow keys or A and D, and jump with Space or W.

You should have a character that falls onto the ground, runs, and jumps. Press Escape to close the player.

If it did not work

• The character falls forever — the ground has no static body, or its physics is switched off.
• Nothing moves — the behaviour is on the wrong entity, or the player has no dynamic body.
• Nothing is visible — check the entity's Layer is Main, and that X and Y are inside the 1280×720 stage.
• It falls through the ground — the ground is on a layer, not a body. Layers control drawing order only; collision needs physics.

Next: turn a single ground bar into a level worth exploring.
