[MilesThatch]

GM Version: GM:S2
Target Platform: Windows
Download: OBJ Importer Project file.
Links: N/A

Summary:
You will learn the structure of an OBJ 3D file.
We will go over each line of code of the included OBJ importer.
We will make a custom 3D model, texture it, convert it using our importer and use it in a blank 3D GM:S2 project.

By the end of this tutorial, You will know how Game Maker Studio 2 handles 3D objects and you will be able to code your own obj importer that can be built straight into your game.

This is great, will definitely finish watching the whole tutorial when I have some spare time. GMS needed a proper tutorial for obj models.
Thanks

This was a very well put together tutorial Thanks for sharing.

Just so you know, string addition in GMS 1.4 is as simple as

str = "Hello";
str += " World";

I doubt it's changed between 1.4 and GMS 2?

EDIT: Typo in the code...

 

[Kenjiro]

Wouldn't that be str += " World"?

 

[Nadder]

Wouldn't that be str += " World"?

Yep, just a typo lol. In the tutorial though he uses string_replace to do addition in strings and states that's just the way you do it in GMS.

 

[Kenjiro]

Yeah, no. Your example is definitely the way to go!

real(value) fails because value is a string of ""
