Building the world
LESSON 05 1:45
Props from kits
Add game-ready props, change them, colour and place them
Ask Claude Code for props GameStudio's kits make game-ready props: rocks, crates, barrels, trees, fences and more. They're not in Blender's Add menu: you ask for them in Claude Code. Here: a crate, a barrel, a mossy rock and a pine tree.
The props appear in Blender Claude checks the kits and builds all four in your level. Each one is a finished model, standing on the lawn.
Click the rock To change one, select it first. Click the rock.
Ask for a bigger rock Then say what to change. Claude sees what you selected. Make this rock bigger, with a different shape.
The rock rebuilds in place It rebuilds the rock from its kit with a new size and a new seed. The seed picks the shape, and the same seed always gives the same rock.
Click the barrel Next, click the barrel.
Ask for a palette colour Now a colour. The kits share one material palette: stone, woods, metals, brick and more. Paint this barrel brick red.
The barrel turns red Claude gives the barrel's wood the palette's brick red. The iron hoops and the lid stay as they were.
Open the Material tab In the Properties, open the Material tab. There it is: G S Brick, the palette's shared brick material. Change it here, and every prop that uses it follows.
Ask to stack it Claude places props, too. Say: now put it on top of the crate.
It snaps onto the crate It moves the barrel over the crate and snaps it onto the first surface below, so nothing floats or sinks. The same snap sets props on hills and slopes.
Turn on Game in the header For a last look, turn on Game in the 3D View's header, to see the props the way the game draws them.
Props from kits That's it: ask for props from the kits, change their size, seed or colour, and place them. Every change Claude makes can be undone.
LESSON 06 1:28
A procedural world in two minutes
Forests, paths, rivers and cliffs that stay editable
Describe the world you want Claude Code is open in a new starter project. In its terminal, describe the world you want, in plain words.
Claude lays the ground Claude looks at the scene first, then swaps the flat lawn for a terrain seventy metres across.
A path along a curve Next, a dirt path along a curve. It's a geometry nodes road: it follows the ground and levels a bed into it.
A river and a bridge The river carves its own channel into the ground. Claude measures both banks and lays a wooden bridge across, with rails.
Cliffs ring the level Then cliffs, all the way round, along the terrain's edge.
Cottages from modular parts Two cottages go up beside the path, each one built from wall, window and door modules.
Trees with keep-out zones Last, the forest. Trees are scattered over the ground, but they keep clear of the path, the river, the houses and the player.
Open the Modifiers tab And it all stays editable. The whole forest is one object, still selected. In the Properties, open the Modifiers tab, the wrench.
Set Density to 0.08 These are the scatter's inputs. Set Density to zero point zero eight.
Turn on Game in the header Blender fills in more trees at once, still clear of the path and the river. Now turn on Game in the 3D View's header.
Scroll to zoom in This is the Scene view: the game's own renderer, drawing your world while you build it. Scroll to get closer.
Your world, as the game draws it Every part stays a live recipe. Change it by hand or ask Claude, then press F5 to play.
LESSON 07 1:59
Asset libraries and prefabs
Make props once, place copies, edit them all at once
Open Game Assets Here's Gem Island, with a crate and a barrel made from GameStudio's kits, both selected. To reuse them, open Game Assets in the 3D View's header.
Click Add Selected to Library... There are no asset libraries yet. Click Add Selected to Library.
Tick One Asset per Object The library is called props: it's saved in your project's assets folder, as props dot blend. Tick One Asset per Object, so the crate and the barrel become two assets.
Tick Replace with Instance Tick Replace with Instance, so the ones in the level become copies of the library too.
Click OK Prefab stays on: library assets are prefabs, so your game's code can spawn them too. Click OK.
Click Place for the barrel Game Assets now lists the props library: the barrel and the crate. Place puts a copy at the 3D cursor, on the right. Place a barrel.
Click Replace for the crate Changed your mind? Replace swaps the selected copy for another asset, in the same spot. Make it a crate.
Press Ctrl+S to save Every copy only links to the library. Save the level with Control S.
Press Ctrl+O to open a file Now change the original. It's in the library file, so press Control O to open it.
Go up to the project folder You're in the project's scenes folder. Go up one folder.
Click the assets folder Click the assets folder, where the libraries live,
Click Open and click Open to go in.
Click props.blend Click props dot blend, the library file,

Press S, type 1.5, Enter Make it bigger: press S, type one point five, and press Enter.
Press Ctrl+S to save it Save the library with Control S.
Press Shift+Ctrl+O Now back to the level. Shift Control O lists the files you opened recently.
Choose main.blend Choose main dot blend.
Every copy follows the library Back in the level, both crates are bigger, the one you placed and the original. The barrel didn't change. Edit an asset once, and every copy follows, in every level.
Open the Add menu Here's Gem Island, the starter game. Let's make it pretty, without any code. First, a sea: in the 3D View's header, open the Add menu.
Choose Mesh Choose Mesh,
Choose Plane then Plane.
Open the Add Plane panel A small plane appears. Open the Add Plane panel at the bottom left: it adjusts what you just added.
Set Size to 200 m Set its Size to two hundred metres: water all around the island.
Set Z to -0.3 m And set its Z to minus zero point three, so the water sits just below the lawn.
Turn on Game in the header Now turn on Game in the header. The Scene view draws the level with the game's own renderer, as players will see it.
Ask Claude for a sunset The sky and sun come from GameStudio's sky kit, which has no panel, so ask Claude Code: a warm sunset with light fog. It switches the sky to its sunset preset with a lower sun, and turns on the world's mist, which the game draws as fog.
Open the Material tab There's the sunset, fading into the haze. Now turn the plane into water. In the Properties, open the Material tab
Click New and click New.
Scroll down to Game Scroll down to the Game panel.
Open the Game Shader menu It picks the game shader that draws this material in the game. Open the Game Shader menu.
Open Water The library's thirty-three shaders come in groups. Open Water

Scroll down to Wave Length Scroll down to its settings.
Set Wave Length to 15 m The defaults already look good. For an open sea, set Wave Length to fifteen metres.
Press F5 to play Now press F5 to play.
Click Play in the game Click Play on the title screen.
Gem Island at sunset There it is in the game: warm sunset light, haze in the distance, and waves rolling in around the island, all without code. Press F8 to stop.
Open the GameStudio menu Let's give a gem some new behaviour, written in TypeScript. Open the GameStudio menu.
Choose New Component... Choose New Component. A component is data you attach to objects.
Name it Bob Name it Bob.
Click Create Click Create. GameStudio writes src/components/bob.ts from a template, and opens it in your code editor.
Give it two fields Swap the example field for two of your own: how far it bobs, and how fast. Then save the file.
Open the GameStudio menu again Bob holds the data. The behaviour goes in a system. Open the GameStudio menu again,
Choose New System... and choose New System.
Name it Bob Name it Bob as well. GameStudio calls it Bob System.
Open the Query list Query picks the objects the system works on. Open the list,
Choose Bob and choose Bob: every object with a Bob component.
Click Create Click Create. The new system's update runs every frame, for each of those objects.
Make it bob Swap the example for a few lines. wave gives the height at any moment, and each frame the object moves by how much the wave changed. Save it.
Click a gem Back in Blender, click a gem to select it.
Click Add Component In the Properties, click Add Component.
Choose Bob Bob is in the list now, under Gameplay. Choose it.
Scroll down to Bob Scroll down. There's Bob, with the description from its file, and your two fields.
Set Height to 0.5 Set its Height to half a metre.
Press F5 to play Press F5 to play.
Click Play in the game Click Play on the title screen.
Watch the gem bob And the gem bobs up and down. Change the system and save it while the game runs: it hot-reloads, and you see the change right away.
Your first component and system That's the pattern: a component holds the data, a system holds the behaviour, and you tune the fields in Blender.
Ask Claude for a rigged character Here's Gem Island, with Claude Code running in the project, as in lesson four. GameStudio's rigged character comes from a kit that Claude builds, so ask Claude to swap the player for one.
Watch Claude build the character Claude deletes the old player, builds a rigged character from the kit, and gives it the player's components and the camera. It's an armature called Player, with a skinned mesh.
Open the Editor Type menu Its animations are Blender actions. To see them, turn the Console into the Nonlinear Animation editor: click its Editor Type button.
Drag its top border up Drag its top border up to make room for every track.
See one track per clip Here are the character's clips: Idle, Walk, Run, Jump, Fall and a few more. Each one is a Blender action on its own track, and the game plays them by name.
Click Add Component Now wire them up, with no code. The armature is still selected, and its Game panel in the Properties lists the components Claude gave it. Click Add Component.
Scroll the menu up The list is long, so scroll it up to Animation.
Choose Locomotion Choose Locomotion, under Animation.
Scroll down to Locomotion Scroll down to its settings.
See a clip for each gait Locomotion names a clip for each gait: Idle, Walk, Run, Jump and Fall, the kit's own names. It picks one from how the character moves.
Press F5 to play Press F5 to play.
Click Play in the game Click Play on the title screen. That also hands your keyboard to the game.
Hold W to run Hold W, and it runs: Locomotion plays the Run clip as soon as it's fast enough.
Turn with D, jump with Space Turn with D and press Space, and it jumps: Locomotion plays the Jump clip on the way up, and Fall on the way down.
Press Shift+Esc Shift Escape gives you the mouse back,
Press F8 to stop and F8 stops the game.
A character that walks and jumps That's an animated player, with no code. For moves of your own, like a landing or an attack, ask Claude for an animation graph.
Ask Claude Code for an enemy Gem Island is open, with Claude Code running in the project. First, an enemy. Ask Claude for a red one at the far end of the lawn, behind a low stone wall.
Click the Enemy Claude builds both from GameStudio's kits. The enemy already has a kinematic RigidBody and a capsule Collider, which it needs to walk. Click it to select it.
Click Add Component In the Properties, the Object tab's Game panel lists its components. Click Add Component.
Choose NavAgent Choose NavAgent, under Navigation. It walks the enemy to a target along the navigation mesh, around anything solid.
Click the lawn, the Ground Now the navigation mesh itself. Click the lawn to select the Ground.
Click Add Component Click Add Component again,
Choose NavMesh and choose NavMesh. When the level loads, the game builds the walkable floor from every solid collider, and keeps paths an Agent Radius away from walls. The defaults suit a person-sized enemy.
Open the GameStudio menu The enemy still needs somewhere to go. That's a job for a system. Open the GameStudio menu
Choose New System... and choose New System.
Name it Chase Name it Chase. The dialog shows the file it makes, in the systems folder.
Click Create Click Create. The new file opens in your code editor.
Point the enemies at the player Replace the example with this. Every frame, an enemy within fifteen metres takes the player as its target, and its NavAgent plans a path around anything in the way. Farther off, nav dot stop keeps it waiting. Save the file.
Press F5 to play Press F5 to play.
Click Play in the game Click Play on the title screen.
The enemy goes around the wall The enemy can't walk through the wall,
It heads for the wall's end so it heads for the end,
It comes around the wall comes around it, and walks straight to you. Its NavAgent plans a new path twice a second, so wherever you go, it follows.
An enemy that chases you That's an enemy that chases you: a NavMesh on the ground, a NavAgent on the enemy, and a few lines of code that point it at the player.

LESSON 15 2:00
From one line to a playable game
Claude Code builds a game in Blender from one brief
Describe your game in one line Here's a new Starter project, Sky Gems, with Claude Code open in its folder. Describe your game in one line: collect all the gems on a floating island before the timer runs out.
Claude checks Blender and plans Claude Code checks that Blender is connected, then writes a one-page plan: an island, six gems and a one-minute timer.
Watch the island appear Then it builds with GameStudio's kits: a floating island from the terrain kit replaces the lawn, with the player on it.
Gems become collectibles Six gems follow, each just above the ground, with the Collectible component, so the player can pick them up.
Scroll out to see it float While Claude works, scroll out in the 3D Viewport to see the whole island floating.
Claude writes the timer code The timer is new code: a small TypeScript system that counts down from sixty seconds, and shows Time's up at zero, or if you fall off.
Open the scene list Menus and the HUD are made in Blender too, so Claude opens the screens file. To watch, open the scene list in the top bar.
Type HUD and press Enter Type HUD and press Enter: the HUD is the screen that stays up while you play.
A timer joins the HUD Claude adds a timer to the HUD, across from the score, and saves.
Claude playtests the game Back in the level, Claude playtests in a hidden browser: it presses Play and runs into the first gem. The gem counts, the clock runs, and there are no errors.
Press F5 to play Claude says the game is ready. Press F5 to play it yourself.
Click Play in the game Click Play on the title screen. That also gives the game your mouse and keyboard.
Hold W to grab a gem The clock starts at one minute. Hold W to run to the gem ahead.
One line, one playable game One gem down, and the clock is ticking. From one line, Claude Code built a game you can play, and every part of it is yours to change in Blender.
LESSON 16 1:32
Playtest and fix
Claude Code plays your level, finds what's wrong and fixes it
A gem on a high ledge Here's Gem Island with one change: a stone ledge, two metres high, with the third gem on top. Can the player get it? Let's ask Claude Code to find out.
Open the GameStudio menu Open the GameStudio menu,
Choose Open in Claude Code and choose Open in Claude Code.
Claude Code starts: click Done Claude Code starts in a terminal, in your project folder. Click Done.
Ask for a playtest In the terminal, ask in plain words: can the player collect every gem? Fix anything that's wrong.
Claude reads the level Claude Code connects to Blender and reads the level first: where the player starts, where the gems are, and the new ledge.
It playtests the level Then it playtests. GameStudio plays the game in a hidden browser with scripted keys, and sends back screenshots, the game's state and its logs. Two gems out of three.
It finds the cause The third gem was never picked up: it's two metres up, and the player's jump peaks under one metre. So Claude adds stairs.
Stairs appear in Blender The stairs appear in Blender, up against the ledge.
It adds a Collider It gives them a mesh Collider, shaped like the steps, so the player can walk up them.
The same playtest passes Then it runs the very same playtest again. This time the player climbs the stairs and takes all three gems, and the win screen opens.
Claude saves and reports Claude saves the level, and tells you what was wrong, what it changed, and the proof: the playtest that now passes.
Playtest, fix, playtest again That's the loop: ask Claude Code to playtest, let it fix what fails, and check that the same test passes.
LESSON 17 1:48
