1
00:00:03,400 --> 00:00:05,165
GameStudio works with Claude Code

2
00:00:05,165 --> 00:00:07,783
or with Codex, OpenAI's coding agent.

3
00:00:07,870 --> 00:00:10,616
To build with Codex, open the Edit menu,

4
00:00:11,167 --> 00:00:12,903
and choose Preferences.

5
00:00:14,300 --> 00:00:15,572
Go to Add-ons.

6
00:00:17,000 --> 00:00:20,129
Click the arrow next to GameStudio to show its settings.

7
00:00:20,700 --> 00:00:22,970
Under Coding agent, choose Codex.

8
00:00:23,057 --> 00:00:25,286
From now on, the launcher, the welcome and

9
00:00:25,286 --> 00:00:28,288
the agent button in the top bar open Codex.

10
00:00:28,867 --> 00:00:29,900
That's all it takes.

11
00:00:29,900 --> 00:00:31,393
Close the Preferences.

12
00:00:32,167 --> 00:00:35,169
The agent button in the top bar now says Codex.

13
00:00:35,209 --> 00:00:37,943
To start Codex, open the GameStudio menu,

14
00:00:38,500 --> 00:00:40,468
and choose Open in Codex.

15
00:00:41,667 --> 00:00:44,616
If Codex isn't installed yet, GameStudio offers

16
00:00:44,616 --> 00:00:47,594
to install it, with OpenAI's official installer.

17
00:00:47,681 --> 00:00:49,573
It needs no administrator rights,

18
00:00:49,573 --> 00:00:52,645
and Codex opens in your project when it's ready.

19
00:00:53,200 --> 00:00:56,729
The first time, GameStudio connects Codex to your project:

20
00:00:56,729 --> 00:01:00,068
it adds Codex's copy of the skills and the link to Blender.

21
00:01:00,340 --> 00:01:01,531
Click Open.

22
00:01:02,267 --> 00:01:05,013
Codex starts in a terminal, in your project folder.

23
00:01:05,158 --> 00:01:07,236
The first time, it asks you to sign in,

24
00:01:07,236 --> 00:01:08,601
and to trust the folder.

25
00:01:08,641 --> 00:01:09,855
Click Done.

26
00:01:10,600 --> 00:01:11,761
Now, in the terminal,

27
00:01:11,761 --> 00:01:14,013
tell Codex what you want in plain words.

28
00:01:14,013 --> 00:01:14,571
Here:

29
00:01:14,571 --> 00:01:16,068
put five mossy rocks of

30
00:01:16,068 --> 00:01:18,141
different sizes around the lawn.

31
00:01:18,700 --> 00:01:21,469
Codex looks at the scene first, then builds.

32
00:01:21,614 --> 00:01:23,774
The rocks appear in Blender as it works,

33
00:01:23,774 --> 00:01:26,705
and the status bar shows what Codex is doing.

34
00:01:27,267 --> 00:01:28,370
Codex is done.

35
00:01:28,370 --> 00:01:29,972
When you close it, the agent button

36
00:01:29,972 --> 00:01:32,039
in the top bar still says Codex.

37
00:01:32,039 --> 00:01:33,043
Click it.

38
00:01:33,600 --> 00:01:35,446
It lists everything Codex did,

39
00:01:35,446 --> 00:01:37,368
and each step can be undone.

40
00:01:37,640 --> 00:01:40,171
Next time, click Open in Codex right here,

41
00:01:40,171 --> 00:01:42,581
and Codex starts in your project again.

42
00:01:43,133 --> 00:01:45,786
That's how to use Codex instead of Claude Code:

43
00:01:45,873 --> 00:01:47,429
choose it once in the preferences,

44
00:01:47,429 --> 00:01:49,652
and everything else works the same way.
