Pseudo 3d?

Like Wolfenstein 3d or the original DooM? It was raycasting back in those days. I was wondering if theres any way we could do that with c2? I know Yann did somethin like that in his maze but I dunno how lol =D

In my maze there was no ray casting, it's only front plane and side plane sprites, rotated and scaled to create the scene.

That's why it's always a strict frontal perspective with the POV exactly in the middle of the front plane.

Making a wolfenstein-like... hmmm dunno, I saw a 3D plugin for C2 a while ago here...

Im fine with the 90 degree only turns infact its exactly what I want what I was wonderin tho is how you did it lol

Anyone else have any input on how this could be done in c2?

This page describes how to do ray casting:

Here's a crude implantation:

I have a slow computer so I made the example with a small display.

wow my mind is blown lol. Now to try to figure out how that example works

That's very clever. Well done!

R0J0hound, your "crude" examples always amaze me. Very nice job!

Wastrel Thanks.

Here is an improved example with:

* textured walls

* more precise wall/ray intersections

* angled walls

OK, how in the world is this done? We don't have sprite distortions like that!

thats an amazing effect, works really well

we need a more in depth tutorial to understand this...... pretty please?

Hers a pretty cool example I came across-

The code is not mine, I only made the textures!

Thanks again R0J0hound! I figured out that 2nd example and updated my demo in the creations folder. I like the 2nd example a lot. Using lines to create the walls was a great idea

The first post I made in this topic has a link that explains it somewhat.

Basically what I did is make a top view game. Then I made a sprite for each vertical line across the screen. Then the player on the top view shoots a spread of bullets, one for each vertical line. When a bullet hits a wall then the corresponding vertical slice is made visible and it's height is set to 100*1/distance(bullet, player).

For the 2nd example I used the math here to find more precise wall intersections.

For the texture I first split it into a frame per vertical slice. Then when the bullet(or ray) hits a wall I calc what texture slice to use by where on the line is hit.

New version with more fixes:

* multiple textures

* commented

* changed walls from lines to polygons.

oh nice that version is well done too! amazing!
