3d moving ground

I want to start my first 3d project. I have tried codea for a couple of years, but I really don’t understand how 3d works.

To my project. I want to make a running game, where you run through a forrest or something and have to move left or right to avoid the trees. You run automatically. ( a game like this is in the appstore i think it was into the dead or something )
The main idea I have is, that the ground and the trees are moving in the direction of the player and the player only moves left and right. ( by taping left or right side of the screen ) is this good?
But I don’t know how to make this possible, how to draw this ground textures and the trees ( only 3d rects for the moment ) and make that all moving in 3d.
Has somebody a good tutorial anywhere how to handle with 3d or can explain me if this is a good idea how to make it?
Thank you very much

Are you able to program with Codea for things other than 3D?


@hallomio77 - Yes, Codea can do all that. Something like this (the wraiths disappear when you touch them).


Hopefully this blog will help.


There are many posts on 3D in the blog - look at the index page to find them. I’ve also written an ebook on 3D (look at the top of the index page for a link).


Welcome to 3D! There’s a lot to learn, but it’s amazing fun.

I recommend looking at @Xavier’s 3D tile engine. It’s fairly easy to analyze. For a basic prototype of the game you describe, you could almost use it out-of-the-box:

  • put the camera in the middle of the little rolling box
  • replace the walls with trees
  • replace the floor with ground

…it would be a fast way to get pretty darn close
