Protect, pause, undo, and trust only what you know

Click-by-click video tutorial, 1:48. GameStudio 0.1.0, Blender 5.2.2 or newer.

## 00:03 Step 1: Claude saves a checkpoint first

Claude Code is building in Gem Island. Before a big change like this ring of gems, it saves a checkpoint: a copy of the scene to go back to.

## 00:11 Step 2: Click Claude in the top bar

Say you don't like the ring. Click Claude in the top bar.

## 00:15 Step 3: Click create_from_kit

Its recent actions are listed here. Click the one that made the gems.

## 00:20 Step 4: Click Undo to Here

Blender selects them. Click Undo to Here.

## 00:23 Step 5: Click Undo to confirm

It also undoes everything after that action, so it asks first. Click Undo.

## 00:29 Step 6: Press Esc to close it

The ring is gone. Press Escape to close the panel.

## 00:32 Step 7: Click a gem

Now say this gem is exactly where you want it. Click it,

## 00:36 Step 8: Click Claude again

open the Claude panel again,

## 00:39 Step 9: Click Protect

and click Protect: Claude may not change it now.

## 00:43 Step 10: Click Pause

Ask Claude to move the gems closer, and the call is refused: one of them is protected. To stop every change, click Pause.

## 00:51 Step 11: Click Resume

Now even the other gems are refused, and Claude is told you paused it. Click Resume.

## 00:57 Step 12: Press Esc to close it

Tell it to go on, and it moves the two gems it may change, and saves. Press Escape.

## 01:03 Step 13: Open the GameStudio menu

Last, a project someone sent you, saved in Downloads. Open the GameStudio menu,

## 01:08 Step 14: Choose Open Project...

choose Open Project,

## 01:11 Step 15: Go to Downloads

go to Downloads,

## 01:14 Step 16: Select Coin Hop

select the project's folder,

## 01:17 Step 17: Press Enter to open it

press Enter to open it,

## 01:19 Step 18: Click Open Game Project

and click Open Game Project.

## 01:22 Step 19: Read it, then click Trust

The level opens, but GameStudio asks before it runs any of the project's code: its scripts, its packages and the game's dev server. Trust only projects from people you trust. Click Trust.

## 01:35 Done: Trusted, and set up

GameStudio remembers your answer and sets the project up. Protect, Pause, checkpoints, Undo to Here and Trust keep you in control.
