I have a question, is the wall collision fix in the raycast.lua file?

Of course

 

[Jwiz33]

Of course

Alright, good to hear. I wanted to make sure that index.lua was just a demo of the features, and that I didn't have to use it as a base, I could start from scratch.

Yeah, the entire engine is in raycast3d.lua

Did you include demos in the latest release?

You can find a complete tech demo in the release which shows some features like textured walls, noclip mode, camera rotations, player movement and so on.

The demo is included.
EDIT: Ninja'd

So, I was trying to draw a 'hand' to the screen, which worked, but it makes the screen flicker.
I didn't draw it as a graphic, should I do that?

It depends on your code anyway using GPU for rendering is always the best thing to do

 

[Rinnegatamante]

Today changes:

- Added strafing support for player (movePlayer with LEFT/RIGHT dir)
- Added possibility to change colors for player in minimap, non textured walls, floor, sky
- Improved a bit texture rendering
- Added 3D support (renderLeftScene / renderRightScene) [N3DS untested, O3DS needs accuracy >= 5 for a good framerate in fullscreen mode]

I'm going to check some things before pushing a new commit in the repository. (Atm some of these features area already pulled pn GitHub).

 

[Rinnegatamante]

Fixxed a couple of bugs (player collision not properly working on some cases and angles rendering not properly working in some cases) and made a bit faster the renderer.

I've also found a bug in texture rendering (it seems horizontal offset of the texture is not properly calculated.

Anyway, pushed new version on GitHub if someone wants to use it.

 

[Rinnegatamante]

I've also added some screenshots in the OP.

Is it possible to do this without knowing how to code?

What do you mean?
Engine is pretty simple to use but you'll need Lua knowledge to use it.

Ok. Sorry. I just wanted to make my own labyrinth. I can't code

 

[Rinnegatamante]

Added a basic bullet physic (it means you can now know were the player is watching. I'll probably update the tech demo to showcast this feature.

 

[Jacklack3]

All we need now is a program to visually make 3d levels!

 

[Rinnegatamante]

And shading support added too! (Needs some improvements but it's a first step).
It will be useful for some effects like fog, night, underwater and similars.
In the screenshot is also viewable the new bullet physic (the red cell in the minimap is the one currently "shooted" by player)
